The document discusses how blockchain technology can be used to detect and prevent money laundering through a distributed ledger system with smart contracts and algorithms. A blockchain-based solution would allow financial institutions and regulators to collaboratively monitor transactions across the network in real-time, flagging suspicious activity. The tamper-proof nature of blockchain ledgers could provide immutable records for compliance assessments now and in the future. The document advocates a phased approach for organizations to explore blockchain technology for anti-money laundering through prototypes and partnerships.

2 The global impact of money laundering is staggering; with
related transactions estimated at 2 to 5% of global GDP
36% of
organisations
report being
victimised by
economic crime
Fraudulent
misinvoicing of
trade transactions
is a key component
of illicit fin. flows
Compliance-related
expenditures have
risen by more than
50% over the last
three years
Rising visibility
linking money
laundering to global
terrorism financing,
trafficking, etc
Every year, roughly $1 trillion flows illegally out of developing and emerging economies due to crime, corruption, and tax evasion—
more than these countries receive in foreign direct investment and foreign aid combined
Every year money laundering channels around $2 trillion worth of proceeds from various illicit
activities. Less than 1% of global illicit financial flows are currently seized by authorities

3 Aging AML solutions are inadequate to meet today’s
business challenges and unprepared for tomorrow’s needs
Despite spending billions of dollars on AML solutions, financial institutions and regulators continue to face an uphill battle in the fight
against money laundering
Existing transaction monitoring systems, based on traditional technology, are unable to keep
pace with growing data sources, volume and complexity of transactions
Growing wave of new digital financial services and
cryptocurreies
Silo’d programs with very limited inter-institution
collaboration
Lack of smart automation, analytical capability and
visualization
Absence of integrated planning and data management

While blockchain technology is today predominantly being used within the ‘fintech’ context , organizations - both public and private-
are starting to look at use cases beyond financial services

Key features of Blockchain technology
Blockchain technology, by its very nature, lends itself to integrated
decentralized monitoring efforts of financial transactions
The blockchain, a cryptographic ledger comprising of a digital log of transactions shared across a public or
private network, can address many of the pitfalls of existing transaction monitoring systems

A Blockchain-based system with smart contracts (using in-built
algorithms) can help identify and stop suspicious transactions
The distributed system will allow financial institutions to securely parse data through an AML/TFML
engine on the blockchain; with the automation providing high efficiency and ensuring minimum friction
A Blockchain-based platform will give regulators, auditors and other stakeholders an effective and powerful set of tools to monitor
complex transactions and immutably record the audit trail of suspicious transaction across the system

6 The decentralized system will compliment existing AML
applications adding an extra ring of scrutiny & visibility
The distributed ledger based platform will allow one institutional system to alert another of transactions
that could potentially be fraudulent and require further scrutiny
Being cryptographic-ally secure will ensure credibility while the immutability feature of Blockchains will maintain tamper-proof records
for current assessment as well as future analysis
Key Features *
1. Private Permissioned Blockchain network
2. Distinct roles for banks, regulators, exchanges and
other users
3. Distributed system for confidentiality, resiliency, and
scalability
4. Cryptographically secure – encryption/decryption for
visibility to only entities linked to a transaction and
authorized auditors/regulators
5. Auditing at multiple levels.
6. Logs immutably recorded, providing a single version of
the truth with a complete audit trail of (suspicious)
transaction across the system

Guiding principles:
 Set up a lab-like environment. Start small. Begin with a few select processes that can be showcased to a wider audience to
highlight benefits and prime adoption.
 Secure alignment. Press for cross-industry participation - Central Bank, Regulator, Banks, Intermediaries like clearing houses, etc
 Aconsortia-based approach can accelerate the integration with key existing systems as well as the rollout across participants
