Executive Summary
In the wake of the 2009 financial crisis, regulatory bodies around the world realized the need to make financial institutions undergo
supervised rigorous tests to ascertain their robustness. Although financial institutions were subject to such conditional testing earlier, the
continued impact of the crisis on markets led regulatory bodies to devise advance methods and risk framework to plug gaps.
Stress testing of financial institutions involves simulation techniques to gauge the impact of certain shocks and stressed macroeconomic
variables on the performance and stability of the institutions and eventually the markets. It includes the use of computer-based
quantitative methodologies (models, techniques, etc.) to assess the financial capacity of these institutions under hypothetical and,
sometimes, highly customized scenarios. These scenarios – hypothetical potential crisis events – are developed by regulatory bodies and
are generally based on the current economic situation as the base case. Further, these scenarios are developed or created as shock events
with prolonged effects solely for the purpose of conducting the tests. Financial institutions also need to develop their own scenarios
specific to their firm under a scenario-expansion exercise. All institutions submit detailed reports to regulatory bodies for their review,
suggestions, and approval. Following their review, regulators release a consolidated report on the tests.
Stress testing also allows regulators to assess banks’ resilience to a range of macroeconomic shocks and ensures banks have sufficient
capital to withstand these shocks. In addition, these tests evaluate the capital planning, as well as risk assessment, and modeling
capabilities of banks. These hypothetical adverse scenarios are accompanied by a baseline scenario to evaluate the relative loss of a bank
under normal macroeconomic conditions.
Although the rules and acts are similar across the globe, various authorities worldwide have their own sets of rules and acts, which define
their requirements for effective risk management. In reality, they follow the requirements of the Basel Accords.
»	 This paper dwells on the qualitative aspects of stress testing, including the need and requirements, origination and evolution over the
years, and the different stress-testing methods employed by major regulatory bodies: the European Banking Association (EBA), the
Federal Reserve (Fed), and the Prudential Regulatory Authority (PRA)

Evolution of Stress Testing
Stress testing is not a new concept. It has been in existence for a long time, but in various other forms and not as part of any mandatory
regulatory exercise. Banks and financial institutions have been using stress-testing techniques, such as the Black Scholes model and the
Monte Carlo method, since 1970s. These exercises, usually run by consultants for internal assessment and risk management only, were
completely unsupervised and based on an institution’s perspective of
economic conditions.
As the markets became more vulnerable to risky business activities and suffered from shocks around the world, financial regulatory
authorities (especially central banks) and the governments of countries woke up to the importance of supervised risk management
exercises. Consequently, since mid-1990s, regulators have stepped up efforts, enacting various acts that created committees and bodies
and spelling out rules institutions had to comply with.
A part of Bank of International Settlements (BIS) based in Basel, the Basel Committee on Banking Supervision (BCBS) issues banking
supervision regulations. BCBS – a committee of banking supervisory authorities – was established to provide a forum for regular
cooperation in banking supervisory matters increase the understanding of key supervisory issues and enhance banking-supervision quality
worldwide. The committee frames standards and best practices guidelines and in capital adequacy, effective and cross-border banking
supervision, efficient market and operational risk management, etc.
BCBS was also formed to frame a set of broad supervisory guidelines and standards for voluntary implementation by the authorities of
member nations across their own national systems. These guidelines, seek to closely monitor financial risks faced by banks and financial
institutions and safeguard them from such risks by establishing supervisory controls on these risks. On the basis of the recommendations
and the guidelines, the various member nations form their own acts and committees, eventually frame stress-testing activities.
Key takeaways:
The major changes in the regulatory stress-testing framework were made after the 2009 financial crisis, as regulatory bodies around
the world realized the deficiencies in risk measurements of banks to cope with adverse economic scenarios and the ripple effect of the
crisis on other economies. Since then, all major economies have developed sophisticated methods for stress testing banks to ensure
that same crisis is not repeated.
What is Regulatory Stress Testing
Stress testing involves scenario testing and a review of the capital adequacy ratios of financial institutions under hypothetical financial
crisis events, which help determine the steps that need to be taken to help these institutions withstand such crises. The capital adequacy
ratios provide an idea of the level of liquidity in each bank and ensure they do not end up insolvent. By preventing financial institutions
from going bust, stress testing ensures the stability of financial markets, especially global systemically important banks (G-SIBs), which are
considered “too big to fail” and whose collapse would impact economies around
the world.
This mandatory regulatory exercise is carried out by analyzing the models used by the institutions to predict their capital positions
(profits, cash flow positions, etc.). Quantitative methods (Monte Carlo, etc.) are used for the simulation of the models to arrive at capital
positions and compare with the regulatory-requirement levels. Unless the required levels are met, the regulatory body does not allow the
institutions to continue with their existing models and plans. The institutions are required to incorporate the suggestions and changes and
comply with the requirements to get certified by the regulatory body as “having passed” the stress test.
G-SIBs generally undergo multiple stress-testing exercises, most of which are mandatorily carried out by regulatory bodies, and a few
are performed by these banks themselves, the results of which need to be reported to their respective regulatory body. In both cases,
models pertaining to the predictions of balance sheet items, risk-weighted assets (RWAs), net income, etc. are simulated on the basis
of macroeconomic scenarios assumed over a “planning horizon” to arrive at post-stress-level values. This “planning horizon” and the
macroeconomic scenarios are determined as per the capital action plans of the regulatory body and the financial institution in question.

behind conducting such tests is common across regulators: evaluation of the resilience of banks in an adverse economic situation. All
stress tests are forward-looking quantitative and qualitative assessments of banks.

Stress Testing Across the World
DFAST/CCAR
Dodd-Frank Act supervisory stress testing (DFAST), along with comprehensive capital analysis and review (CCAR), are forward-looking
supervisory stress tests conducted by the Fed to identify whether the largest banks in the US have sufficient capital to negate the impact
of stressful economic and financial market conditions. Banks with consolidated assets of $50bn or more are evaluated to ensure they have
robust forward-looking capital planning processes to mitigate their unique risks.
DFAST (complementary to CCAR) shows how bank holding company (BHC) capital ratios can change under a hypothetical set of
economic conditions and macroeconomic scenarios developed by the Fed. It serves as a raw material for quantitative assessment in CCAR
after a bank has incorporated its capital planning process and planned capital distributions. Other than carrying out supervisory tests,
BHCs in the US have to conduct annual company-run stress tests for the same supervisory scenarios, planning horizon, and capital actions
assumed in DFAST. They also have to perform a midcycle stress test under company
developed scenarios.
Shocks are calibrated under three macroeconomic scenarios (baseline, adverse, and severely adverse) to estimate a BHC’s projected
losses, pre provision net revenue, and capital adequacy. Both DFAST and CCAR assume the same set of stress scenarios and
macroeconomic shocks to project net income, total assets and RWAs. The difference lies in capital action assumptions. DFAST employs
a standardized set of capital action assumptions to project post-stress capital ratios, whereas CCAR uses a BHC’s planned capital actions
to determine a bank’s resilience in stressful scenarios. Results of DFAST and CCAR differ significantly because of the difference in capital
action assumptions. If the Fed believes a bank’s capital action is not robust to withstand stressful economic scenarios on quantitative
and qualitative grounds in a CCAR assessment, bank may not be able to engage in planned capital distribution and may have to resubmit
capital plans to the Fed.
Evolution of Regulations
After the 2009 financial crisis, regulatory bodies in the US realized existing regulations and stress-testing techniques were inefficient in
measuring a bank’s risk profile and resilience in sustaining itself during an economic crisis, which could strain its capital adequacy and
ability
to survive.
To make the supervisory process more robust, the Fed carried out an assessment of capital in 2009, called the SCAP (supervisory capital
assessment program), on the 19 largest US BHCs, which had weakened amid the financial and economic downturn.
The SCAP assessed whether the 19 BHCs had sufficient capital to absorb losses under a scenario more severe than the one in 2009. The
SCAP used two scenarios: baseline and more severe scenarios. Ten of the 19 BHCs failed the SCAP, as their capital was below the required
ratio. They were asked to prepare a new capital plan and raise the necessary capital to meet the target. SCAP test results reinstated
confidence in the public by reducing uncertainty about the health of BHCs, which helped stabilize the US financial system.
The results and analysis of SCAP helped the Fed initiate CCAR and DFAST in 2010 to ascertain the capital adequacy and capital planning
of large BHCs. BHCs with total consolidated assets of more than $50bn have to participate in the regulatory stress tests (CCAR and
DFAST). Banks with total consolidated assets of more than $10bn have to conduct their company-run stress tests under the same
supervisory scenarios, planning horizon, and capital actions assumed in DFAST.
8	 CCAR Results – 2016
Process
CCAR and DFAST both assume the same set of scenarios (baseline, adverse, and severely adverse), macroeconomic shocks, and planning
horizon to evaluate the capital adequacy of a bank. The adverse and severely adverse scenarios are not forecasts, but hypothetical
scenarios developed by the Fed to gauge the impact of macroeconomic shocks on the stability of banks. The baseline scenario
assumes a profile similar to that used in the average projection of US real economic activity, inflation, and interest rates. Twenty-eight
macroeconomic variables are calibrated over a nine-quarter planning horizon under these three scenarios to project balance sheets,
RWAs, net income, and post stress capital levels and regulatory capital ratios. Of these 28 variables, 16 capture economic activity, asset
prices, and domestic interest rates in the US economy and real GDP growth, inflation, and US/foreign currency exchange rate in each of
the four countries/country blocs (eurozone, UK, Developing Asia, Japan).
Projections in CCAR and DFSAT vary, as their capital action assumptions are different. DFAST is a forward-looking quantitative assessment
with standardized capital action assumptions to measure stress capital adequacy ratios. All the participating BHCs have to maintain post-
stress capital ratios above the applicable minimum regulatory capital ratios during each quarter of the planning horizon of three years to
pass the stress test.
CCAR is a broader exercise; it covers the quantitative and qualitative assessments of a participating BHC. In the quantitative calculation,
supervisory post-stress capital analysis is based on the projections of net income, total assets, and RWAs. Macroeconomic shocks and
scenarios assumed in DFAST are calibrated by incorporating a BHC’s capital planning and distribution to evaluate the BHC’s capability to
adopt capital measures mentioned in the BHC baseline scenario.
Quantitative-assessment results also include BHC’s internal stress tests under supervisory and the bank’s own scenarios. The Fed can
object to the capital plans of a BHC on quantitative grounds if the BHC is unable to maintain the minimum required capital ratio
throughout the planning horizon in post-stress capital analysis.
The qualitative assessment focuses on key areas, such as a BHC’s risk management framework, control infrastructure, capital planning
and distributions, and internal capital planning process, to determine the sum and composition of capital a bank has to maintain
throughout the period of a severe economic crisis scenario. The supervisory test also evaluates the rationale behind a BHC’s capital plan
and assumptions of the underlying capital plan. It also involves a BHC’s material risk identification process and capital planning process to
evaluate specific risks faced by the bank under stress. Reasons for objections from the Fed on qualitative aspects include the following:
»	 Material supervisory issues still unresolved
»	 Unreasonable or inappropriate assumptions and analyses underlying the capital plan of a BHC
»	 Unreasonable or inappropriate methodologies for reviewing the robustness of capital planning process of a BHC
»	 Belief a BHC’s planning process or capital distribution is unlawful or unsafe practices, which are not permitted by the Fed
Models used to ascertain the impact of stressful scenarios on balance sheets, RWAs, pre-provision net revenue PPNR, and projected losses
are developed or selected by the Fed. The same sets of models and assumptions are applied across all BHCs. The modeling approach is
forward-looking so that it integrates outcomes outside historical experience and is appropriately conservative and consistent with the
intent of the stress-testing exercise. Models used in supervisory stress tests are reviewed by an independent model validation team.
Key takeaways:
Supervisory stress-test models are developed by the Fed and are applicable to all participating BHCs. Banks also have to develop their
own models for company-run stress tests under the guidance of the Fed. Model development and scenario design exercise require
considerable expertise, along with functional knowledge of risk domain. For model development and scenario expansion, banks need
to consider all the granular risk variables and shocks specific to them.

CCAR/DFAST Framework – 2016 vs 2015
Thirty-three large BHCs participated in the 2016 supervisory stress test compared with 31 BHCs in 2015. A detailed comparison of the 2016
and 2015 supervisory stress tests is provided below.
Key Model Changes
» Operational risk: To improve the stability of a model and minimize year-over-year variation in projected losses, changes were made in
the risk projection methodology, with additional modifications in the historical simulation model to project operational risk losses. The
changes resulted in an increase in operational risk losses (as percentage of RWAs), effectively higher losses for firms reporting fewer tail
risks but still vulnerable to losses from such events.
» MRWA Model: To better differentiate the sensitivity of each component to scenario variables and to align estimates more closely
to the market risk rule. The effect of changes could be seen in the positively correlated movement of incremental risk charge and
comprehensive risk measure with projected credit market volatility. The projected MRWA declined moderately in aggregate.
» Supervisory Capital evaluation: Greater precision was incorporated in capital ratio denominator adjustments and in assumptions on
the relationship between mortgage servicing assets and the associated deferred tax liabilities. As a result, capital ratios fell, affecting
items fully deducted from regulatory capital.
DFAST 2016 vs DFAST 2015 Results
»	 In aggregate, banks had a stronger balance sheet in 2016 than in 2015
»	 Capital increased in 2016 with credit-quality improvement in some material loan portfolios
»	 Results also showed reductions in illiquid securitization exposures on the trading books and projected losses due to mortgage-related
litigations and settlements
»	 The 2015 severely adverse scenario consisted of, among others, assumptions of corporate credit quality worse than the severe
recession, which amplified already widening corporate bond spreads, a decline in equity prices, and an increase in equity price volatility.
The severely adverse scenario in 2016 included a severe recession and negative short-term interest rates, limiting the decline in equity
prices and the increase in market volatility
»	 Changes in the scenario were expected to increase projections for net income in the aggregates in 2016. However, the effects were
varied across firms
»	 With lesser stress in equity markets in 2016, firms active in trading and market activities saw smaller losses in net income, while firms
involved in more traditional lending activities were affected more from negative short-term rates and greater stress in the
	 real economy
CCAR 2016 vs CCAR 2015
» 	The Fed has continually raised the bar on process enhancements that it expects BHCs to meet the requirements through stronger
frameworks. The 2016 stress test was more stringent than previous stress tests
» 	Overall, capital adequacy levels of the participating BHCs improved from 2015
» 	 Even though all BHCs (except a couple of them) improved their capital planning compared with 2015, qualitative deficiencies were
observed in their planning process
» 	For the second straight year, Santander and Deutsche Bank received “Objection to Capital Plans” owing to their weak risk management
framework, governance, and oversight
» 	In 2015 Bank of America received “Conditional Non-Objection,” based on its weakness in estimate modeling practices. This year
(2016), Morgan Stanley has been given “Conditional Non-Objection” owing to weaknesses in its scenario design, modeling, and
governance and control practices

Graphical Comparison of Stress Scenario Severity
A simplistic comparison of the severity of the stress scenario between 2015 and 2016 (severely adverse scenario) is provided below. Only
projections have been compared. Q1 2016 to Q4 2018 values in the 2016 stress test are compared with Q1 2015 to Q4 2017 values in
the stress test in 2015. The quarters in 2016 are compared with their respective quarters in the 2015 scenario, for example, Q1 2016 is
compared with Q1 2015 in the 2015 scenario. The comparison leads to the conclusion the 2016 scenario is more severe than the
2015 scenario.

Key takeaways:
Over time, stress tests are not only becoming more sophisticated but also covering a broader range of risk variables at more severity
levels. Banks need to focus strongly on stress-testing exercises every year to ensure the smooth functioning of the business and
financial sta bility.

EBA
Stress testing for banks and financial institutions under the purview of the EU financial market is overseen and supervised by the EBA. The
EBA – an independent EU authority – oversees the EU banking sector to ensure financial stability in the EU and safeguard the integrity,
efficiency, and functioning of the banking sector.
The EBA helps create the European Single Rulebook in banking, which provides a single set of prudential rules consistent for all EU
financial institutions under its purview. The association also promotes convergence in supervisory practices and assesses risks and
vulnerabilities across the institutions in the EU banking sector. This is carried out regularly in the form of stress testing in these institutions,
duly supervised by the EBA.
In what follows, we look at the evolution of the EU regulatory environment and the birth of the current regulations.
Evolution of Regulations
»	 The Council of European Union issued Capital Adequacy Directive (1993) and implemented it in 1995. Targeting banking and
nonbanking firms, the directive was meant for banks to calculate their capital estimate using VaR techniques. It was revised twice, in
1998 and in 2006, with CAD renamed to capital requirement directive (CRD).
»	 The CRD was introduced in 2006 to incorporate Basel II guidelines, which resulted in the introduction of the CRD I package. The CRD
II and CRD III packages were adopted in 2009 and 2011, respectively. 2013 saw the transposition of the CRD IV package with the
incorporation of Basel III guidelines under the name Capital Requirements Regulation (CRR) and Directive (CRD IV).
»	 The Committee of European Banking Supervisors (CEBS), an independent advisory group on banking supervision in the EU, was
established in 2004 under the European Commission, with a revised charter in 2009. The role involved advising the European
Commission on measures on lending activities, contributing toward the implementation of directives and practices, and improving
supervisory cooperation including the exchange of information. Stress tests were started in 2009, and the second edition was
conducted in 2010, after which the CEBS was superseded by the EBA under European Supervisory Authorities (ESA), formed as a part
of the European System of Financial Supervision (ESFS) framework for Financial Supervision (in operation since 2011) and developed
through the Lamfalussy Process after the 2009 financial crisis.
»	 The main role of the EBA comprises the creation of the European Single Rulebook in banking, which provides a set of standard rules for
financial institutions throughout the EU, creating a level-playing field and providing protection to consumers, depositors, and investors.
Other tasks include the promotion of practices toward the application of rules, assessment of risks and vulnerabilities in the banking
sector, and other activities involving the maintenance of the health of the EU banking sector.
Process
The 2016 EU-wide stress testing of banks was the fifth edition of the regulatory exercise. The first test was conducted in 2009. The stress
test is similar to those conducted in other financial systems across the globe, with the tests involving baseline and severe scenarios to
arrive at capital ratios and values, which can be compared with the regulatory required capital adequacy ratios and hurdle rates. The
regulatory authorities recommend, through feedback and suggestions, actions to be taken by the firms that pass or fail these tests.
After the 2009 and 2010 stress tests under CEBS, the EBA came into existence in 2011. The ESFS framework for financial supervision,
implemented in 2011, was proposed by the European Commission after the 2009 financial crisis. It includes ESA, European Systemic Risk
Board (ESRB), Joint Committee of the ESA, and the national supervisory authorities of member states.
The ESFS framework includes microprudential and macroprudential oversights at the EU level. The ESA, the Joint Committee of ESA, and
the competent national supervisory authorities are responsible for microprudential oversight. The ESA comprises European Securities
and Markets Authority (ESMA), European Insurance and Occupational Pensions Authority (EIOPA), and the EBA. The ESRB is responsible
for macroprudential oversight of the ESFS framework and includes representatives from the European Central Bank (ECB), supervisory
authorities in national central banks of EU member states, and the European Commission.
The regulatory process involves the EBA’s devising a methodology applicable to all banks undergoing the tests and checked by the
supervisors. The competent authorities are responsible for quality assurance and supervisory reaction functions. The ESRB designs
common adverse scenarios for stress tests, while the European Commission provides the baseline scenario. The EBA also provides EU
descriptive statistics on risk parameters for consistency checks in addition to acting as a data hub for the final dissemination of the
common exercise to ensure transparency and proper comparison, as well as proper coordination and communication among the various
entities for the exercise.
In the 2011 and 2014 stress tests, the methodology included the assessment of banks involved on the basis of capital shortfalls, labeling
them as “pass” or “fail,” followed by appropriate actions. From 2016, the methodology has changed toward assessing the banks on their
forward-looking capital planning. Even though hurdle rates and capital thresholds have been done away with, the results of the latest tests
would be used as inputs for the supervisory review and evaluation process (SREP), which would help authorities decide on Pillar 2 capital
requirements. Additional risk drivers, especially operational and conduct risks, have been included.

Further, for greater homogeneity and comparability, the sample size has been reduced to 51 banks (representing 70% of banking sector
assets in the eurozone, non-eurozone EU member states, and Norway). Criteria for inclusion in the sample included a minimum total
consolidated asset size of EUR20bn, consistent with the criterion used for inclusion in a sample of banks reporting supervisory data to the
EBA. There was scope for including additional institutions and banks on the request of competent authorities, provided the institutions
held more than EUR100bn in assets and mandatory restructuring plans (agreed by the European Commission).
Key takeaways:
The SREP is a mechanism under Pillar 2 capital requirements that ensures institutions have adequate arrangements, approaches,
procedures, and mechanisms, as well as capital and liquidity, for the sound management and coverage of their own risks to which they
are or might be exposed to, including those revealed by stress testing and risks they may pose to the financial system.
Unlike in the US supervisory stress test, banks have to develop their own models to assess the impact of stressed scenarios on credit,
market, and operational risks. The models are developed under the guidance of regulatory bodies and are subject to a number of
conservative constraints. Banks need to include all material risk factors while developing the models.
EU-wide Stress Test Framework – 2016 vs 2014
In the 2016 stress test, 51 banks were assessed, which represented 70% of the EU banking assets (compared with 123 banks in 2014).
Pass-fail criteria were not included in 2016, whereas the criteria for passing the test in 2014 included capital hurdle rates of 8% common
equity Tier 1 (CET1) in baseline and 5.5% CET1 in adverse scenarios.
2016 saw the inclusion of the impact of risk drivers under credit, market, and operational risks. Common risks included in the 2014 edition
were credit, market, sovereign, securitization, and cost of funding risks while operational and conduct risks were excluded.
The treatment of FX lending has been explicitly added in the scope of the 2016 exercise. Banks that had significant foreign currency
exposure (above the threshold limit) were asked to include the altered creditworthiness of their respective obligors by evaluating
exposures denominated in foreign currency of the borrower at the asset class level for each country of counterparty in the 2016 stress test.
Similar to the 2014 stress test, the assessment of the impact of risk drivers on the solvency of banks has been the primary focus of the
2016 stress test. A static balance sheet has been assumed over the time horizon of three years, with the same business mix and model,
zero growth, and no capital measures in the 2016 EU-wide stress test, similar to the 2014 stress test.
The adverse scenario in the 2016 stress test is stricter than that in the 2014 test, as it includes more risk coverage and conservative
elements. The shocks have been front-loaded, which ensures the adverse impact materializes earlier during the test horizon.
In the 2016 stress test, the ECB perceived the current level of capitalization in the euro banking system to be satisfactory. Therefore, the
intent of the 2016 exercise focused more on assessing the remaining vulnerabilities and the impact of a hypothetical adverse market
scenario on banks. The 2014 stress test consisted of an asset quality review and a supervisory stress test aimed at determining possible
capital shortfalls and ascertaining whether any banks needed immediate recapitalization measures.
Modifications in the Pillar 2 structure, including a breakdown into Pillar 2 requirements and Pillar 2 guidance, imply that results of 2016
EU-wide stress test are not directly comparable with the SREP 2015. Therefore, previous comprehensive assessments are quite different
from those in the 2016 stress test.
Overall, the banks tested in 2016 have been found to be more resilient than those in the 2014 test. Twenty-four of the 123 banks that
participated in the 2014 stress test failed. This year, results exhibit resilience in the EU banking sector as a whole.

Key takeaways:
There are major changes in the 2016 stress test framework compared with the previous stress tests conducted by the EBA. Banks have
a steep learning curve to cope with in the new regulatory regime.

UK PRA
Stress testing for banks and financial institutions under the purview of the UK financial market is overseen and supervised by the Bank of
England (BoE) and the PRA. The Financial Policy Committee (FPC) was established in 1998 primarily to help achieve the BoE’s objective
of financial stability, including in growth and employment levels, in the UK while identifying, monitoring, and taking actions to remove or
reduce the effect of systemic risks, thereby enhancing the robustness of the UK financial system. In 2013, the FPC had asked the BoE and the
PRA to propose steps for stress testing the UK banking system at regular intervals.These tests would help assess the capital adequacy of the
UK financial system. Similar to stress tests elsewhere, these tests provide a quantitative, forward-looking assessment of a financial system.
In what follows, we discuss the evolution of the UK regulatory environment and the birth of the current regulations.
Evolution of Regulations
Under Financial Securities Act 1986, the Securities and Investments Board Ltd (SIB) was incorporated, which oversaw and presided over
various self-regulating organizations (SROs) using a mix of governmental regulations and self-regulations. A series of scandals, especially
culminating in the collapse of Barings Bank, led to the realization for the need to end self-regulation of the financial industry and consolidate
the regulatory responsibilities split across multiple regulators.TheSIB revokedThe Financial Intermediaries, Managers and Brokers Regulatory
Association’s (FIMBRA) status as an SRO in 1994, and members were moved into Personal Investment Authority (PIA).
In 1997, the SIB was renamed Financial Services Authority (FSA), and its powers were expanded through Financial Services and Markets Act
2000. In addition to regulating financial firms, insurance companies, and financial advisors, it started to regulate mortgage businesses from
2004 and general insurance intermediaries from 2005. Following the worldwide regulatory failure of the banks during the 2009 crises, the
UK government decided to restructure the financial regulations and abolish the FSA. It passed the Financial Services Act 2012 through Royal
assent, and it was announced that the responsibilities of FSA would be delegated to a number of new agencies, viz. the Financial Conduct
Authority (FCA), the PRA, and Bank of England.
According to the Financial Services Act 2012, the FCA would monitor the financial activities of the banking system, while the PRA would
regulate financial firms, including banks, investment banks, building societies, and insurance companies. In its current capacity, the FCA
regulates financial firms, focusing on regulating the conduct of wholesale and retail financial services providers, especially those involved
in marketing financial products. It can specify minimum standards, specify requirements of products, and investigate organizations and
individuals, thus maintaining the integrity of the UK financial market. On the other hand, the PRA establishes standards and oversees
financial institutions at an individual level. Its role is primarily defined in terms of three statutory objectives:
»	 Promoting the safety and soundness of firms it regulates,
»	 Supervising insurance firms to safeguard the interest of policyholders,
»	 Facilitating effective competition
Regarding the promotion of safety and soundness, the primary focus is on the harm firms can cause to the integrity and stability of the UK
financial system.
The UK Parliament recently passed the Bank of England and Financial Services Act 2016.The act puts the BoE at the center of UK’s economic
and financial systems by making it better equipped to fulfil the vital role of overseeing monetary policy and financial stability in the UK.
Process
The 2016 stress testing of banks and financial systems under the UK financial system is the third edition of the regulatory exercise, with the
first set of tests performed and results published in 2014.The stress test of UK firms involves an evaluation similar to the assessment of their
US and European counterparts, with the tests around baseline and severe scenarios and testing criteria involving capital adequacy ratios
and hurdle rates. Actions to be taken by the firms that pass or fail the tests are based on qualitative assessments, involving feedback and
suggestions, by the regulatory authorities.
In 2013, the BoE, under the guidance of the FPC and the PRA Board, released a paper “A framework for stress testing the UK banking
system,” to discuss the appropriate design framework for the tests in the medium term. Regarding the frequency and timeliness of tests,
the framework suggests that the regularity of the tests is important since these tests represent an important assessment of the stability of
the financial system. Hence, the frequency of the tests should be annual, as this would encourage the firms and the authorities to invest
continually in stress-testing capabilities. Further, the focus would be on guarding against “risk illusion,” forcing the firms to consider the
types of risks that threaten their stability. Regarding concurrency, it is important to conduct the tests for all firms in parallel, as the resilience
of a system is tested on a whole and allows the authorities to check for any amplification factors to risk and carry out changes and revisions
to the approach, strengthening the exercise on the whole. Stress Test results are published 6-7 months after balance sheet information has
been used as inputs, in line with the practice in the US, as the inputs are relevant and the analysis performed can be rigorous in nature.
16	 CCAR Results – 2016
Regarding the coverage of the tests, banks and firms are included on the basis of three main considerations:
»	 Importance to financial stability in the UK
»	 Legal and regulatory status, which allows the FPC and the PRA to take appropriate actions (depending on the results)
»	 Activities, which should be sufficiently similar so that the framework can be kept simple and no separate analytical toolkits would need to
be developed
Based on the above, the stress-testing exercise would include major UK banks (ranked on the basis of asset size, with a threshold of GBP50bn).
Additionally, the merits of including medium-sized banks have been recognized, with the option of either including them in the framework but
performing only limited scenario tests or not including them, but keeping the framework flexible.
For scenario-building, the framework points out the tests need to be conducted, in general, on:
»	 Common scenarios, applied across all banks undertaking the stress tests, designed by the FPC in consultation with the PRA (This would
include a common baseline scenario and a common stressed scenario.)
»	 Bespoke scenarios designed by the banks and approved by the PRA Board, with severity matching with at least the common scenarios of
the FPC
For modeling the scenarios, the framework suggests the use of a suite of models, calibrating the macroeconomic and market variables to
estimates of banks’ profitability and capital ratios. This makes sense, as it is not easy to realistically capture all risks through a single model,
which may even give rise to “model risk.” Furthermore, different models bring different insights and perspectives and provide an array of
mediums to cross check the results and prevent manipulation. With this objective, the framework suggests using four broad models:
»	 Granular, regulator-developed stress-testing models
»	 Coarser, system-wide stress-testing models
»	 Banks’ own stress-testing models
»	 Other “satellite” models
Key takeaways:
Unlike the US and EBA stress tests, final projections are evaluated using both company-developed models and models developed by
the regulator in the PRA assessment.
Internal models would cover material risks specific to a bank and ensure improvements in its risk management and modeling
capabilities, while regulatory models cross check the results of banks and ensure consistency across banks.

PRA Framework – 2014 and 2015 vs 2016
The results of the 2016 test are yet to be published. 2014 and 2015 had similar features, but the 2016 test has certain key differences from
the previous two years:
»	 Similar to 2015, 2016 covers seven major UK banks (vs eight in 2014).
»	 2014 and 2015 covered baseline and stress scenarios, whereas in 2016, in an updated approach for stress testing, the BoE devised an
“annual cyclical scenario” (ACS) to assess risks associated with conditions in credit, financial, and other asset markets. The ACS covers
both adverse and baseline scenarios. A second type – the exploratory scenario, expected to be used from 2017 – seeks to probe the
resilience of the system to risks emerging as threats to its financial stability.
»	 The 2014 stress test mainly focused on domestics risks related to UK households and unemployment levels as a result of a sharp rise
in interest rates. The 2015 stress test delved more on global risks associated with a pronounced contraction in growth in the euro area,
other emerging market economies, and China. A broader range of domestic and global risks has been incorporated in the 2016 stress
test calibrated under the ACS framework compared with previous stress tests.Some global shocks under the ACS framework are akin to
the 2015 stress test, and some domestic shocks (GDP and unemployment levels) in the 2016 stress test are related to the 2014 stress
test. The scenarios in the 2016 stress test are more severe than those in the 2015 and 2014 stress tests.
»	 Similar to 2015, the time horizon for 2016 is five years (vs three years in 2014).
»	 Another major change was in the hurdle rate framework. In 2015, the threshold for capital requirement for risk-based capital was 4.5%
of RWAs, to be met with CET1 for RWAs, while adequacy for leverage terms, to be met with Tier 1, was 3% of the leverage exposure
measure. In 2016, apart from the 4.5% CET1, which is a Pillar 1 requirement, Pillar 2A capital has been included to mitigate the risk not
covered by Pillar 1. A minimum Tier 1 leverage ratio of 3% in an adverse scenario is required. Additionally, a second inclusion is based
on “Systemic Reference Point,” where G-SIB buffer is included, where capital requirement would increase the hurdle rates in a phased
manner, in increments of 25% each year.
»	 In the 2014 stress test, the PRA Board concluded three (The Cooperative Bank, the Royal Bank of Scotland Group, and Lloyds Banking
Group) of the eight banks needed to improve their capital plan. The Cooperative Bank was asked to resubmit its capital plan. In the
2015 stress test, the PRA Board concluded two of the seven banks had capital inadequacy. But since these banks had already taken
measures to improve their capital position, they were not required to submit a revised capital plan.
Comparison between Baseline Scenario and Stress Scenario
A comparison of the severity of the stress scenario with respect to the baseline scenario is provided below. Both historical data and
projections have been taken into account to analyze the severity of the stressed variables with respect to the baseline scenario as well as
historical numbers. Data from Q1 2000 to Q4 2015 are historical values and data from Q1 2016 to Q4 2020 are projections.

Conclusion
Following the 2009 crisis, stress testing has become one of the most important tasks for banks. To ensure financial stability and
confidence among investors and the general public, banks need to undergo rigorous stress tests, in which their capital adequacy is
evaluated under hypothetical severe scenarios. These scenarios are more severe than the historical crises that shook the world. The
rationale behind these stress tests is to ensure such events do not recur and deteriorate the economy.
Supervisory bodies around the world have adopted sophisticated stress-testing methodologies to evaluate financial-system resilience.
These bodies have developed common risk factors and scenarios applicable to all banks in an economy. In addition, banks need to develop
their own scenarios to evaluate risks specific to them. Not only do supervisory authorities develop models to calculate the impact of risk
factors on the balance sheet and profits, but banks also need to develop their own models to cover firmwide risks under the guidance of
regulators. With changes occurring in the regulatory environment every year, banks need to adapt to the new rules and regulations by
improving their risk framework.
To adapt to the new regulatory regimes, banks have started outsourcing the task of stress testing. Outsourcing firms with expertise in
regulatory environments are able to help banks better understand regulatory requirements. This has helped banks identify all material
risks specific to them and create better risk models and scenarios for better capital planning and control.
Stress testing is not limited to stressing on macroeconomic variables in hypothetical scenarios; it also requires a bank to improve its risk
assessment and modeling capabilities, capital planning, and reporting and accounting standards. Risk assessment exercises performed by
banks cannot be improved drastically overnight; they are enhanced gradually in phases. Banks need to gain insights into their strengths
and weaknesses to improve their risk assessment and modeling practices; this would, in turn, improve the quality of their stress-testing
capabilities.
There are key differences in the risk framework and guidelines of regulatory bodies around the world, but the core activities of banks and
the challenges they face are similar. The primary activities of banks require expertise in scenario development, data management, model
development and governance, revenue and balance sheet modeling, loss forecasting, process reengineering, and documentation. Other
than supervisory scenarios, banks have to design internal scenarios. Scenario expansion requires breaking down macroeconomic variables
into granular risk factors specific to a bank. Revenue and balance sheet modeling requires consistency in assumptions across the balance
sheet and the need to capture contagion effects of modeling. Banks need to adhere to the model risk management guidelines issued by
their regulators; they also need to continually improve their existing models by developing challenger models. In addition, models need to
be comprehensively documented to include descriptive analysis of model methodology, assumptions, requirements, and model validation
results.
From our experience, we can infer stress testing is likely to remain one of the most important tasks for banks and regulatory requirements
would continue to increase over time. Regulators have been closely monitoring banks’ risk assessment capabilities since 2009 crisis,
and passing stress tests has become imperative for the smooth functioning of banks. This is why banks need to ensure stress testing
is one of their primary objectives. The latest results of stress tests show various large banks around the world are resilient to adverse
macroeconomic scenarios, but banks still need to keep pace with increasing regulatory requirements. The road to success lies in improving
their ability to identify and mitigate risks.

  • 3. Moody’s Analytics Knowledge Services 3 Executive Summary In the wake of the 2009 financial crisis, regulatory bodies around the world realized the need to make financial institutions undergo supervised rigorous tests to ascertain their robustness. Although financial institutions were subject to such conditional testing earlier, the continued impact of the crisis on markets led regulatory bodies to devise advance methods and risk framework to plug gaps. Stress testing of financial institutions involves simulation techniques to gauge the impact of certain shocks and stressed macroeconomic variables on the performance and stability of the institutions and eventually the markets. It includes the use of computer-based quantitative methodologies (models, techniques, etc.) to assess the financial capacity of these institutions under hypothetical and, sometimes, highly customized scenarios. These scenarios – hypothetical potential crisis events – are developed by regulatory bodies and are generally based on the current economic situation as the base case. Further, these scenarios are developed or created as shock events with prolonged effects solely for the purpose of conducting the tests. Financial institutions also need to develop their own scenarios specific to their firm under a scenario-expansion exercise. All institutions submit detailed reports to regulatory bodies for their review, suggestions, and approval. Following their review, regulators release a consolidated report on the tests. Stress testing also allows regulators to assess banks’ resilience to a range of macroeconomic shocks and ensures banks have sufficient capital to withstand these shocks. In addition, these tests evaluate the capital planning, as well as risk assessment, and modeling capabilities of banks. These hypothetical adverse scenarios are accompanied by a baseline scenario to evaluate the relative loss of a bank under normal macroeconomic conditions. Although the rules and acts are similar across the globe, various authorities worldwide have their own sets of rules and acts, which define their requirements for effective risk management. In reality, they follow the requirements of the Basel Accords. » This paper dwells on the qualitative aspects of stress testing, including the need and requirements, origination and evolution over the years, and the different stress-testing methods employed by major regulatory bodies: the European Banking Association (EBA), the Federal Reserve (Fed), and the Prudential Regulatory Authority (PRA) » The differences and similarities among Stress Testing exercises across regulators » It also highlights new stress-testing principles adopted by regulators and key differences between the current and previous stress-testing practices
  • 4. 4 CCAR Results – 2016 Evolution of Stress Testing Stress testing is not a new concept. It has been in existence for a long time, but in various other forms and not as part of any mandatory regulatory exercise. Banks and financial institutions have been using stress-testing techniques, such as the Black Scholes model and the Monte Carlo method, since 1970s. These exercises, usually run by consultants for internal assessment and risk management only, were completely unsupervised and based on an institution’s perspective of economic conditions. As the markets became more vulnerable to risky business activities and suffered from shocks around the world, financial regulatory authorities (especially central banks) and the governments of countries woke up to the importance of supervised risk management exercises. Consequently, since mid-1990s, regulators have stepped up efforts, enacting various acts that created committees and bodies and spelling out rules institutions had to comply with. A part of Bank of International Settlements (BIS) based in Basel, the Basel Committee on Banking Supervision (BCBS) issues banking supervision regulations. BCBS – a committee of banking supervisory authorities – was established to provide a forum for regular cooperation in banking supervisory matters increase the understanding of key supervisory issues and enhance banking-supervision quality worldwide. The committee frames standards and best practices guidelines and in capital adequacy, effective and cross-border banking supervision, efficient market and operational risk management, etc. BCBS was also formed to frame a set of broad supervisory guidelines and standards for voluntary implementation by the authorities of member nations across their own national systems. These guidelines, seek to closely monitor financial risks faced by banks and financial institutions and safeguard them from such risks by establishing supervisory controls on these risks. On the basis of the recommendations and the guidelines, the various member nations form their own acts and committees, eventually frame stress-testing activities. Key takeaways: The major changes in the regulatory stress-testing framework were made after the 2009 financial crisis, as regulatory bodies around the world realized the deficiencies in risk measurements of banks to cope with adverse economic scenarios and the ripple effect of the crisis on other economies. Since then, all major economies have developed sophisticated methods for stress testing banks to ensure that same crisis is not repeated. What is Regulatory Stress Testing Stress testing involves scenario testing and a review of the capital adequacy ratios of financial institutions under hypothetical financial crisis events, which help determine the steps that need to be taken to help these institutions withstand such crises. The capital adequacy ratios provide an idea of the level of liquidity in each bank and ensure they do not end up insolvent. By preventing financial institutions from going bust, stress testing ensures the stability of financial markets, especially global systemically important banks (G-SIBs), which are considered “too big to fail” and whose collapse would impact economies around the world. This mandatory regulatory exercise is carried out by analyzing the models used by the institutions to predict their capital positions (profits, cash flow positions, etc.). Quantitative methods (Monte Carlo, etc.) are used for the simulation of the models to arrive at capital positions and compare with the regulatory-requirement levels. Unless the required levels are met, the regulatory body does not allow the institutions to continue with their existing models and plans. The institutions are required to incorporate the suggestions and changes and comply with the requirements to get certified by the regulatory body as “having passed” the stress test. G-SIBs generally undergo multiple stress-testing exercises, most of which are mandatorily carried out by regulatory bodies, and a few are performed by these banks themselves, the results of which need to be reported to their respective regulatory body. In both cases, models pertaining to the predictions of balance sheet items, risk-weighted assets (RWAs), net income, etc. are simulated on the basis of macroeconomic scenarios assumed over a “planning horizon” to arrive at post-stress-level values. This “planning horizon” and the macroeconomic scenarios are determined as per the capital action plans of the regulatory body and the financial institution in question.
  • 5. Moody’s Analytics Knowledge Services 5 CCAR/DFAST EBA PRA Inclusion » BHCs with $50bn or more of consolidated assets have to undergo supervisory stress test (DFAST/ CCAR) » In the 2016 supervisory stress test, 33 BHCs participated in the regulatory stress test » A minimum total consolidated asset size of EUR20bn was necessary for inclusion in the 2016 stress test » The EU-wide stress test is conducted on a sample that forms 70% of banking sector assets in the eurozone, non-eurozone EU member states, and Norway (51 banks in 2016) » Seven banks and building societies, which accounted for 80% of the outstanding stock of PRA-regulated banks, were covered in the 2016 stress test Tests » CCAR is a supervisory annual stress test to evaluate a bank’s capital adequacy, capital planning process, and planned capital distributions in stressful economic scenarios » DFAST is a quantitative assessment of the effects of stressful economic and financial market conditions on a BHC’s capital » Other than the annual supervisory stress tests, conducted by the Fed, all financial companies with total consolidated assets more than $10bn are required to conduct annual company-run stress tests » The EU-wide stress test is an annual supervisory test that provides a common analytical framework to EU banks and the EU banking system to evaluate the resilience of the banks to macroeconomic and microeconomic shocks, as well as the capital position of the banks under an adverse economic scenario » Annual cyclical scenario is a concurrent stress test conducted by the FPC and the PRA to identify resilience of the banks under hypothetical stressful economic scenarios and ensure the banks are sufficiently capitalized » The biennial exploratory scenario stress test evaluates risks not covered under the annual cyclical stress test. It explores the emerging or latent threats to the stability of the economy. Unlike the cyclical stress test, the exploratory stress test may vary in nature for each exercise Scenarios » Three common scenarios are baseline, adverse, and severely adverse scenarios » The baseline scenario follows a profile similar to average projections of US real economic activity, inflation, and interest rates » The adverse scenario covers weak economic activities, deflationary pressures, near-zero short-term interest rates in the US, and tight financial conditions for corporates and households » The severely adverse scenario encompasses severe global recession, heightened corporate financial stress, a sharp drop in asset prices, and negative yields on short- term US Treasury securities » The EBA’s exercise evaluates the performance of the banks under common macroeconomic baseline and adversescenarios » The adverse scenario reflects four systemic risks that currently represent the most material threats to EU banks: • Low liquidity in secondary market • Weak profitability prospects and financial conditions • Increased concerns over debt sustainability • Low nominal growth of economy • Rising shadow banking sector, amplified by spillover and liquidity risk » It is less strict than CCAR » The ACS test a UK bank undergoes is similar to those subjected to their US and European counterparts, with tests around baseline and severe scenarios and testing criteria involving capital adequacy ratios andhurdle rates: • The adverse scenario projects vulnerabilities across financial markets and the domestic economy and a global downturn in output growth. A sharp fall in asset prices, along with volatility in the financial and property markets, is also included » The biennial exploratory scenario explores emerging or latent threats to the stability of the economy » It is less strict than CCAR Comparison Among CCAR/DFAST, EBA, and PRA Stress Tests
  • 6. 6 CCAR Results – 2016 CCAR/DFAST EBA PRA Scenario design » Various methods of scenario development allow flexibility in changing correlations and dependencies among risk factors » The scenario design framework is not limited to historical episodes.

All stress tests are forward-looking quantitative and qualitative assessments of banks.
  • 7. Moody’s Analytics Knowledge Services 7 Stress Testing Across the World DFAST/CCAR Dodd-Frank Act supervisory stress testing (DFAST), along with comprehensive capital analysis and review (CCAR), are forward-looking supervisory stress tests conducted by the Fed to identify whether the largest banks in the US have sufficient capital to negate the impact of stressful economic and financial market conditions. Banks with consolidated assets of $50bn or more are evaluated to ensure they have robust forward-looking capital planning processes to mitigate their unique risks. DFAST (complementary to CCAR) shows how bank holding company (BHC) capital ratios can change under a hypothetical set of economic conditions and macroeconomic scenarios developed by the Fed. It serves as a raw material for quantitative assessment in CCAR after a bank has incorporated its capital planning process and planned capital distributions. Other than carrying out supervisory tests, BHCs in the US have to conduct annual company-run stress tests for the same supervisory scenarios, planning horizon, and capital actions assumed in DFAST. They also have to perform a midcycle stress test under company developed scenarios. Shocks are calibrated under three macroeconomic scenarios (baseline, adverse, and severely adverse) to estimate a BHC’s projected losses, pre provision net revenue, and capital adequacy. Both DFAST and CCAR assume the same set of stress scenarios and macroeconomic shocks to project net income, total assets and RWAs. The difference lies in capital action assumptions. DFAST employs a standardized set of capital action assumptions to project post-stress capital ratios, whereas CCAR uses a BHC’s planned capital actions to determine a bank’s resilience in stressful scenarios. Results of DFAST and CCAR differ significantly because of the difference in capital action assumptions. If the Fed believes a bank’s capital action is not robust to withstand stressful economic scenarios on quantitative and qualitative grounds in a CCAR assessment, bank may not be able to engage in planned capital distribution and may have to resubmit capital plans to the Fed. Evolution of Regulations After the 2009 financial crisis, regulatory bodies in the US realized existing regulations and stress-testing techniques were inefficient in measuring a bank’s risk profile and resilience in sustaining itself during an economic crisis, which could strain its capital adequacy and ability to survive. To make the supervisory process more robust, the Fed carried out an assessment of capital in 2009, called the SCAP (supervisory capital assessment program), on the 19 largest US BHCs, which had weakened amid the financial and economic downturn. The SCAP assessed whether the 19 BHCs had sufficient capital to absorb losses under a scenario more severe than the one in 2009. The SCAP used two scenarios: baseline and more severe scenarios. Ten of the 19 BHCs failed the SCAP, as their capital was below the required ratio. They were asked to prepare a new capital plan and raise the necessary capital to meet the target. SCAP test results reinstated confidence in the public by reducing uncertainty about the health of BHCs, which helped stabilize the US financial system. The results and analysis of SCAP helped the Fed initiate CCAR and DFAST in 2010 to ascertain the capital adequacy and capital planning of large BHCs. BHCs with total consolidated assets of more than $50bn have to participate in the regulatory stress tests (CCAR and DFAST). Banks with total consolidated assets of more than $10bn have to conduct their company-run stress tests under the same supervisory scenarios, planning horizon, and capital actions assumed in DFAST.
  • 8. 8 CCAR Results – 2016 Process CCAR and DFAST both assume the same set of scenarios (baseline, adverse, and severely adverse), macroeconomic shocks, and planning horizon to evaluate the capital adequacy of a bank. The adverse and severely adverse scenarios are not forecasts, but hypothetical scenarios developed by the Fed to gauge the impact of macroeconomic shocks on the stability of banks. The baseline scenario assumes a profile similar to that used in the average projection of US real economic activity, inflation, and interest rates. Twenty-eight macroeconomic variables are calibrated over a nine-quarter planning horizon under these three scenarios to project balance sheets, RWAs, net income, and post stress capital levels and regulatory capital ratios. Of these 28 variables, 16 capture economic activity, asset prices, and domestic interest rates in the US economy and real GDP growth, inflation, and US/foreign currency exchange rate in each of the four countries/country blocs (eurozone, UK, Developing Asia, Japan). Projections in CCAR and DFSAT vary, as their capital action assumptions are different. DFAST is a forward-looking quantitative assessment with standardized capital action assumptions to measure stress capital adequacy ratios. All the participating BHCs have to maintain post- stress capital ratios above the applicable minimum regulatory capital ratios during each quarter of the planning horizon of three years to pass the stress test. CCAR is a broader exercise; it covers the quantitative and qualitative assessments of a participating BHC. In the quantitative calculation, supervisory post-stress capital analysis is based on the projections of net income, total assets, and RWAs. Macroeconomic shocks and scenarios assumed in DFAST are calibrated by incorporating a BHC’s capital planning and distribution to evaluate the BHC’s capability to adopt capital measures mentioned in the BHC baseline scenario. Quantitative-assessment results also include BHC’s internal stress tests under supervisory and the bank’s own scenarios. The Fed can object to the capital plans of a BHC on quantitative grounds if the BHC is unable to maintain the minimum required capital ratio throughout the planning horizon in post-stress capital analysis. The qualitative assessment focuses on key areas, such as a BHC’s risk management framework, control infrastructure, capital planning and distributions, and internal capital planning process, to determine the sum and composition of capital a bank has to maintain throughout the period of a severe economic crisis scenario. The supervisory test also evaluates the rationale behind a BHC’s capital plan and assumptions of the underlying capital plan. It also involves a BHC’s material risk identification process and capital planning process to evaluate specific risks faced by the bank under stress. Reasons for objections from the Fed on qualitative aspects include the following: » Material supervisory issues still unresolved » Unreasonable or inappropriate assumptions and analyses underlying the capital plan of a BHC » Unreasonable or inappropriate methodologies for reviewing the robustness of capital planning process of a BHC » Belief a BHC’s planning process or capital distribution is unlawful or unsafe practices, which are not permitted by the Fed Models used to ascertain the impact of stressful scenarios on balance sheets, RWAs, pre-provision net revenue PPNR, and projected losses are developed or selected by the Fed. The same sets of models and assumptions are applied across all BHCs. The modeling approach is forward-looking so that it integrates outcomes outside historical experience and is appropriately conservative and consistent with the intent of the stress-testing exercise. Models used in supervisory stress tests are reviewed by an independent model validation team. Key takeaways: Supervisory stress-test models are developed by the Fed and are applicable to all participating BHCs. Banks also have to develop their own models for company-run stress tests under the guidance of the Fed. Model development and scenario design exercise require considerable expertise, along with functional knowledge of risk domain. For model development and scenario expansion, banks need to consider all the granular risk variables and shocks specific to them.
  • 9. Moody’s Analytics Knowledge Services 9 CCAR/DFAST Framework – 2016 vs 2015 Thirty-three large BHCs participated in the 2016 supervisory stress test compared with 31 BHCs in 2015. A detailed comparison of the 2016 and 2015 supervisory stress tests is provided below. Key Model Changes » Operational risk: To improve the stability of a model and minimize year-over-year variation in projected losses, changes were made in the risk projection methodology, with additional modifications in the historical simulation model to project operational risk losses. The changes resulted in an increase in operational risk losses (as percentage of RWAs), effectively higher losses for firms reporting fewer tail risks but still vulnerable to losses from such events. » MRWA Model: To better differentiate the sensitivity of each component to scenario variables and to align estimates more closely to the market risk rule. The effect of changes could be seen in the positively correlated movement of incremental risk charge and comprehensive risk measure with projected credit market volatility. The projected MRWA declined moderately in aggregate. » Supervisory Capital evaluation: Greater precision was incorporated in capital ratio denominator adjustments and in assumptions on the relationship between mortgage servicing assets and the associated deferred tax liabilities. As a result, capital ratios fell, affecting items fully deducted from regulatory capital. DFAST 2016 vs DFAST 2015 Results » In aggregate, banks had a stronger balance sheet in 2016 than in 2015 » Capital increased in 2016 with credit-quality improvement in some material loan portfolios » Results also showed reductions in illiquid securitization exposures on the trading books and projected losses due to mortgage-related litigations and settlements » The 2015 severely adverse scenario consisted of, among others, assumptions of corporate credit quality worse than the severe recession, which amplified already widening corporate bond spreads, a decline in equity prices, and an increase in equity price volatility. The severely adverse scenario in 2016 included a severe recession and negative short-term interest rates, limiting the decline in equity prices and the increase in market volatility » Changes in the scenario were expected to increase projections for net income in the aggregates in 2016. However, the effects were varied across firms » With lesser stress in equity markets in 2016, firms active in trading and market activities saw smaller losses in net income, while firms involved in more traditional lending activities were affected more from negative short-term rates and greater stress in the real economy CCAR 2016 vs CCAR 2015 » The Fed has continually raised the bar on process enhancements that it expects BHCs to meet the requirements through stronger frameworks. The 2016 stress test was more stringent than previous stress tests » Overall, capital adequacy levels of the participating BHCs improved from 2015 » Even though all BHCs (except a couple of them) improved their capital planning compared with 2015, qualitative deficiencies were observed in their planning process » For the second straight year, Santander and Deutsche Bank received “Objection to Capital Plans” owing to their weak risk management framework, governance, and oversight » In 2015 Bank of America received “Conditional Non-Objection,” based on its weakness in estimate modeling practices. This year (2016), Morgan Stanley has been given “Conditional Non-Objection” owing to weaknesses in its scenario design, modeling, and governance and control practices

  • 12. 12 CCAR Results – 2016 EBA Stress testing for banks and financial institutions under the purview of the EU financial market is overseen and supervised by the EBA. The EBA – an independent EU authority – oversees the EU banking sector to ensure financial stability in the EU and safeguard the integrity, efficiency, and functioning of the banking sector. The EBA helps create the European Single Rulebook in banking, which provides a single set of prudential rules consistent for all EU financial institutions under its purview. The association also promotes convergence in supervisory practices and assesses risks and vulnerabilities across the institutions in the EU banking sector. This is carried out regularly in the form of stress testing in these institutions, duly supervised by the EBA. In what follows, we look at the evolution of the EU regulatory environment and the birth of the current regulations. Evolution of Regulations » The Council of European Union issued Capital Adequacy Directive (1993) and implemented it in 1995. Targeting banking and nonbanking firms, the directive was meant for banks to calculate their capital estimate using VaR techniques. It was revised twice, in 1998 and in 2006, with CAD renamed to capital requirement directive (CRD). » The CRD was introduced in 2006 to incorporate Basel II guidelines, which resulted in the introduction of the CRD I package. The CRD II and CRD III packages were adopted in 2009 and 2011, respectively. 2013 saw the transposition of the CRD IV package with the incorporation of Basel III guidelines under the name Capital Requirements Regulation (CRR) and Directive (CRD IV). » The Committee of European Banking Supervisors (CEBS), an independent advisory group on banking supervision in the EU, was established in 2004 under the European Commission, with a revised charter in 2009. The role involved advising the European Commission on measures on lending activities, contributing toward the implementation of directives and practices, and improving supervisory cooperation including the exchange of information. Stress tests were started in 2009, and the second edition was conducted in 2010, after which the CEBS was superseded by the EBA under European Supervisory Authorities (ESA), formed as a part of the European System of Financial Supervision (ESFS) framework for Financial Supervision (in operation since 2011) and developed through the Lamfalussy Process after the 2009 financial crisis. » The main role of the EBA comprises the creation of the European Single Rulebook in banking, which provides a set of standard rules for financial institutions throughout the EU, creating a level-playing field and providing protection to consumers, depositors, and investors. Other tasks include the promotion of practices toward the application of rules, assessment of risks and vulnerabilities in the banking sector, and other activities involving the maintenance of the health of the EU banking sector. Process The 2016 EU-wide stress testing of banks was the fifth edition of the regulatory exercise. The first test was conducted in 2009. The stress test is similar to those conducted in other financial systems across the globe, with the tests involving baseline and severe scenarios to arrive at capital ratios and values, which can be compared with the regulatory required capital adequacy ratios and hurdle rates. The regulatory authorities recommend, through feedback and suggestions, actions to be taken by the firms that pass or fail these tests. After the 2009 and 2010 stress tests under CEBS, the EBA came into existence in 2011. The ESFS framework for financial supervision, implemented in 2011, was proposed by the European Commission after the 2009 financial crisis. It includes ESA, European Systemic Risk Board (ESRB), Joint Committee of the ESA, and the national supervisory authorities of member states. The ESFS framework includes microprudential and macroprudential oversights at the EU level. The ESA, the Joint Committee of ESA, and the competent national supervisory authorities are responsible for microprudential oversight. The ESA comprises European Securities and Markets Authority (ESMA), European Insurance and Occupational Pensions Authority (EIOPA), and the EBA. The ESRB is responsible for macroprudential oversight of the ESFS framework and includes representatives from the European Central Bank (ECB), supervisory authorities in national central banks of EU member states, and the European Commission. The regulatory process involves the EBA’s devising a methodology applicable to all banks undergoing the tests and checked by the supervisors. The competent authorities are responsible for quality assurance and supervisory reaction functions. The ESRB designs common adverse scenarios for stress tests, while the European Commission provides the baseline scenario. The EBA also provides EU descriptive statistics on risk parameters for consistency checks in addition to acting as a data hub for the final dissemination of the common exercise to ensure transparency and proper comparison, as well as proper coordination and communication among the various entities for the exercise. In the 2011 and 2014 stress tests, the methodology included the assessment of banks involved on the basis of capital shortfalls, labeling them as “pass” or “fail,” followed by appropriate actions. From 2016, the methodology has changed toward assessing the banks on their forward-looking capital planning. Even though hurdle rates and capital thresholds have been done away with, the results of the latest tests would be used as inputs for the supervisory review and evaluation process (SREP), which would help authorities decide on Pillar 2 capital requirements. Additional risk drivers, especially operational and conduct risks, have been included.
  • 13. Moody’s Analytics Knowledge Services 13 Further, for greater homogeneity and comparability, the sample size has been reduced to 51 banks (representing 70% of banking sector assets in the eurozone, non-eurozone EU member states, and Norway). Criteria for inclusion in the sample included a minimum total consolidated asset size of EUR20bn, consistent with the criterion used for inclusion in a sample of banks reporting supervisory data to the EBA. There was scope for including additional institutions and banks on the request of competent authorities, provided the institutions held more than EUR100bn in assets and mandatory restructuring plans (agreed by the European Commission). Key takeaways: The SREP is a mechanism under Pillar 2 capital requirements that ensures institutions have adequate arrangements, approaches, procedures, and mechanisms, as well as capital and liquidity, for the sound management and coverage of their own risks to which they are or might be exposed to, including those revealed by stress testing and risks they may pose to the financial system. Unlike in the US supervisory stress test, banks have to develop their own models to assess the impact of stressed scenarios on credit, market, and operational risks. The models are developed under the guidance of regulatory bodies and are subject to a number of conservative constraints. Banks need to include all material risk factors while developing the models. EU-wide Stress Test Framework – 2016 vs 2014 In the 2016 stress test, 51 banks were assessed, which represented 70% of the EU banking assets (compared with 123 banks in 2014). Pass-fail criteria were not included in 2016, whereas the criteria for passing the test in 2014 included capital hurdle rates of 8% common equity Tier 1 (CET1) in baseline and 5.5% CET1 in adverse scenarios. 2016 saw the inclusion of the impact of risk drivers under credit, market, and operational risks. Common risks included in the 2014 edition were credit, market, sovereign, securitization, and cost of funding risks while operational and conduct risks were excluded. The treatment of FX lending has been explicitly added in the scope of the 2016 exercise. Banks that had significant foreign currency exposure (above the threshold limit) were asked to include the altered creditworthiness of their respective obligors by evaluating exposures denominated in foreign currency of the borrower at the asset class level for each country of counterparty in the 2016 stress test. Similar to the 2014 stress test, the assessment of the impact of risk drivers on the solvency of banks has been the primary focus of the 2016 stress test. A static balance sheet has been assumed over the time horizon of three years, with the same business mix and model, zero growth, and no capital measures in the 2016 EU-wide stress test, similar to the 2014 stress test. The adverse scenario in the 2016 stress test is stricter than that in the 2014 test, as it includes more risk coverage and conservative elements. The shocks have been front-loaded, which ensures the adverse impact materializes earlier during the test horizon. In the 2016 stress test, the ECB perceived the current level of capitalization in the euro banking system to be satisfactory. Therefore, the intent of the 2016 exercise focused more on assessing the remaining vulnerabilities and the impact of a hypothetical adverse market scenario on banks. The 2014 stress test consisted of an asset quality review and a supervisory stress test aimed at determining possible capital shortfalls and ascertaining whether any banks needed immediate recapitalization measures. Modifications in the Pillar 2 structure, including a breakdown into Pillar 2 requirements and Pillar 2 guidance, imply that results of 2016 EU-wide stress test are not directly comparable with the SREP 2015. Therefore, previous comprehensive assessments are quite different from those in the 2016 stress test. Overall, the banks tested in 2016 have been found to be more resilient than those in the 2014 test. Twenty-four of the 123 banks that participated in the 2014 stress test failed. This year, results exhibit resilience in the EU banking sector as a whole.

  • 15. Moody’s Analytics Knowledge Services 15 UK PRA Stress testing for banks and financial institutions under the purview of the UK financial market is overseen and supervised by the Bank of England (BoE) and the PRA. The Financial Policy Committee (FPC) was established in 1998 primarily to help achieve the BoE’s objective of financial stability, including in growth and employment levels, in the UK while identifying, monitoring, and taking actions to remove or reduce the effect of systemic risks, thereby enhancing the robustness of the UK financial system. In 2013, the FPC had asked the BoE and the PRA to propose steps for stress testing the UK banking system at regular intervals.These tests would help assess the capital adequacy of the UK financial system. Similar to stress tests elsewhere, these tests provide a quantitative, forward-looking assessment of a financial system. In what follows, we discuss the evolution of the UK regulatory environment and the birth of the current regulations. Evolution of Regulations Under Financial Securities Act 1986, the Securities and Investments Board Ltd (SIB) was incorporated, which oversaw and presided over various self-regulating organizations (SROs) using a mix of governmental regulations and self-regulations. A series of scandals, especially culminating in the collapse of Barings Bank, led to the realization for the need to end self-regulation of the financial industry and consolidate the regulatory responsibilities split across multiple regulators.TheSIB revokedThe Financial Intermediaries, Managers and Brokers Regulatory Association’s (FIMBRA) status as an SRO in 1994, and members were moved into Personal Investment Authority (PIA). In 1997, the SIB was renamed Financial Services Authority (FSA), and its powers were expanded through Financial Services and Markets Act 2000. In addition to regulating financial firms, insurance companies, and financial advisors, it started to regulate mortgage businesses from 2004 and general insurance intermediaries from 2005. Following the worldwide regulatory failure of the banks during the 2009 crises, the UK government decided to restructure the financial regulations and abolish the FSA. It passed the Financial Services Act 2012 through Royal assent, and it was announced that the responsibilities of FSA would be delegated to a number of new agencies, viz. the Financial Conduct Authority (FCA), the PRA, and Bank of England. According to the Financial Services Act 2012, the FCA would monitor the financial activities of the banking system, while the PRA would regulate financial firms, including banks, investment banks, building societies, and insurance companies. In its current capacity, the FCA regulates financial firms, focusing on regulating the conduct of wholesale and retail financial services providers, especially those involved in marketing financial products. It can specify minimum standards, specify requirements of products, and investigate organizations and individuals, thus maintaining the integrity of the UK financial market. On the other hand, the PRA establishes standards and oversees financial institutions at an individual level. Its role is primarily defined in terms of three statutory objectives: » Promoting the safety and soundness of firms it regulates, » Supervising insurance firms to safeguard the interest of policyholders, » Facilitating effective competition Regarding the promotion of safety and soundness, the primary focus is on the harm firms can cause to the integrity and stability of the UK financial system. The UK Parliament recently passed the Bank of England and Financial Services Act 2016.The act puts the BoE at the center of UK’s economic and financial systems by making it better equipped to fulfil the vital role of overseeing monetary policy and financial stability in the UK. Process The 2016 stress testing of banks and financial systems under the UK financial system is the third edition of the regulatory exercise, with the first set of tests performed and results published in 2014.The stress test of UK firms involves an evaluation similar to the assessment of their US and European counterparts, with the tests around baseline and severe scenarios and testing criteria involving capital adequacy ratios and hurdle rates. Actions to be taken by the firms that pass or fail the tests are based on qualitative assessments, involving feedback and suggestions, by the regulatory authorities. In 2013, the BoE, under the guidance of the FPC and the PRA Board, released a paper “A framework for stress testing the UK banking system,” to discuss the appropriate design framework for the tests in the medium term. Regarding the frequency and timeliness of tests, the framework suggests that the regularity of the tests is important since these tests represent an important assessment of the stability of the financial system. Hence, the frequency of the tests should be annual, as this would encourage the firms and the authorities to invest continually in stress-testing capabilities. Further, the focus would be on guarding against “risk illusion,” forcing the firms to consider the types of risks that threaten their stability. Regarding concurrency, it is important to conduct the tests for all firms in parallel, as the resilience of a system is tested on a whole and allows the authorities to check for any amplification factors to risk and carry out changes and revisions to the approach, strengthening the exercise on the whole. Stress Test results are published 6-7 months after balance sheet information has been used as inputs, in line with the practice in the US, as the inputs are relevant and the analysis performed can be rigorous in nature.
  • 16. 16 CCAR Results – 2016 Regarding the coverage of the tests, banks and firms are included on the basis of three main considerations: » Importance to financial stability in the UK » Legal and regulatory status, which allows the FPC and the PRA to take appropriate actions (depending on the results) » Activities, which should be sufficiently similar so that the framework can be kept simple and no separate analytical toolkits would need to be developed Based on the above, the stress-testing exercise would include major UK banks (ranked on the basis of asset size, with a threshold of GBP50bn). Additionally, the merits of including medium-sized banks have been recognized, with the option of either including them in the framework but performing only limited scenario tests or not including them, but keeping the framework flexible. For scenario-building, the framework points out the tests need to be conducted, in general, on: » Common scenarios, applied across all banks undertaking the stress tests, designed by the FPC in consultation with the PRA (This would include a common baseline scenario and a common stressed scenario.) » Bespoke scenarios designed by the banks and approved by the PRA Board, with severity matching with at least the common scenarios of the FPC For modeling the scenarios, the framework suggests the use of a suite of models, calibrating the macroeconomic and market variables to estimates of banks’ profitability and capital ratios. This makes sense, as it is not easy to realistically capture all risks through a single model, which may even give rise to “model risk.” Furthermore, different models bring different insights and perspectives and provide an array of mediums to cross check the results and prevent manipulation. With this objective, the framework suggests using four broad models: » Granular, regulator-developed stress-testing models » Coarser, system-wide stress-testing models » Banks’ own stress-testing models » Other “satellite” models Key takeaways: Unlike the US and EBA stress tests, final projections are evaluated using both company-developed models and models developed by the regulator in the PRA assessment. Internal models would cover material risks specific to a bank and ensure improvements in its risk management and modeling capabilities, while regulatory models cross check the results of banks and ensure consistency across banks.
  • 17. Moody’s Analytics Knowledge Services 17 PRA Framework – 2014 and 2015 vs 2016 The results of the 2016 test are yet to be published. 2014 and 2015 had similar features, but the 2016 test has certain key differences from the previous two years: » Similar to 2015, 2016 covers seven major UK banks (vs eight in 2014). » 2014 and 2015 covered baseline and stress scenarios, whereas in 2016, in an updated approach for stress testing, the BoE devised an “annual cyclical scenario” (ACS) to assess risks associated with conditions in credit, financial, and other asset markets. The ACS covers both adverse and baseline scenarios. A second type – the exploratory scenario, expected to be used from 2017 – seeks to probe the resilience of the system to risks emerging as threats to its financial stability. » The 2014 stress test mainly focused on domestics risks related to UK households and unemployment levels as a result of a sharp rise in interest rates. The 2015 stress test delved more on global risks associated with a pronounced contraction in growth in the euro area, other emerging market economies, and China. A broader range of domestic and global risks has been incorporated in the 2016 stress test calibrated under the ACS framework compared with previous stress tests.Some global shocks under the ACS framework are akin to the 2015 stress test, and some domestic shocks (GDP and unemployment levels) in the 2016 stress test are related to the 2014 stress test. The scenarios in the 2016 stress test are more severe than those in the 2015 and 2014 stress tests. » Similar to 2015, the time horizon for 2016 is five years (vs three years in 2014). » Another major change was in the hurdle rate framework. In 2015, the threshold for capital requirement for risk-based capital was 4.5% of RWAs, to be met with CET1 for RWAs, while adequacy for leverage terms, to be met with Tier 1, was 3% of the leverage exposure measure. In 2016, apart from the 4.5% CET1, which is a Pillar 1 requirement, Pillar 2A capital has been included to mitigate the risk not covered by Pillar 1. A minimum Tier 1 leverage ratio of 3% in an adverse scenario is required. Additionally, a second inclusion is based on “Systemic Reference Point,” where G-SIB buffer is included, where capital requirement would increase the hurdle rates in a phased manner, in increments of 25% each year. » In the 2014 stress test, the PRA Board concluded three (The Cooperative Bank, the Royal Bank of Scotland Group, and Lloyds Banking Group) of the eight banks needed to improve their capital plan. The Cooperative Bank was asked to resubmit its capital plan. In the 2015 stress test, the PRA Board concluded two of the seven banks had capital inadequacy. But since these banks had already taken measures to improve their capital position, they were not required to submit a revised capital plan. Comparison between Baseline Scenario and Stress Scenario A comparison of the severity of the stress scenario with respect to the baseline scenario is provided below. Both historical data and projections have been taken into account to analyze the severity of the stressed variables with respect to the baseline scenario as well as historical numbers. Data from Q1 2000 to Q4 2015 are historical values and data from Q1 2016 to Q4 2020 are projections.

All rights reserved. 20161110-001 contact_maks@moodys.com | maknowledgeservices.com Conclusion Following the 2009 crisis, stress testing has become one of the most important tasks for banks. To ensure financial stability and confidence among investors and the general public, banks need to undergo rigorous stress tests, in which their capital adequacy is evaluated under hypothetical severe scenarios. These scenarios are more severe than the historical crises that shook the world. The rationale behind these stress tests is to ensure such events do not recur and deteriorate the economy. Supervisory bodies around the world have adopted sophisticated stress-testing methodologies to evaluate financial-system resilience. These bodies have developed common risk factors and scenarios applicable to all banks in an economy. In addition, banks need to develop their own scenarios to evaluate risks specific to them. Not only do supervisory authorities develop models to calculate the impact of risk factors on the balance sheet and profits, but banks also need to develop their own models to cover firmwide risks under the guidance of regulators. With changes occurring in the regulatory environment every year, banks need to adapt to the new rules and regulations by improving their risk framework. To adapt to the new regulatory regimes, banks have started outsourcing the task of stress testing. Outsourcing firms with expertise in regulatory environments are able to help banks better understand regulatory requirements. This has helped banks identify all material risks specific to them and create better risk models and scenarios for better capital planning and control. Stress testing is not limited to stressing on macroeconomic variables in hypothetical scenarios; it also requires a bank to improve its risk assessment and modeling capabilities, capital planning, and reporting and accounting standards. Risk assessment exercises performed by banks cannot be improved drastically overnight; they are enhanced gradually in phases. Banks need to gain insights into their strengths and weaknesses to improve their risk assessment and modeling practices; this would, in turn, improve the quality of their stress-testing capabilities. There are key differences in the risk framework and guidelines of regulatory bodies around the world, but the core activities of banks and the challenges they face are similar. The primary activities of banks require expertise in scenario development, data management, model development and governance, revenue and balance sheet modeling, loss forecasting, process reengineering, and documentation. Other than supervisory scenarios, banks have to design internal scenarios. Scenario expansion requires breaking down macroeconomic variables into granular risk factors specific to a bank. Revenue and balance sheet modeling requires consistency in assumptions across the balance sheet and the need to capture contagion effects of modeling. Banks need to adhere to the model risk management guidelines issued by their regulators; they also need to continually improve their existing models by developing challenger models. In addition, models need to be comprehensively documented to include descriptive analysis of model methodology, assumptions, requirements, and model validation results. From our experience, we can infer stress testing is likely to remain one of the most important tasks for banks and regulatory requirements would continue to increase over time. Regulators have been closely monitoring banks’ risk assessment capabilities since 2009 crisis, and passing stress tests has become imperative for the smooth functioning of banks. This is why banks need to ensure stress testing is one of their primary objectives. The latest results of stress tests show various large banks around the world are resilient to adverse macroeconomic scenarios, but banks still need to keep pace with increasing regulatory requirements. The road to success lies in improving their ability to identify and mitigate risks.
