Mr. Mustaq Mulla, SRFGCC, RCU, Belagavi 1 Unit III Risk Management and Surveillance System in Stock Exchanges Risk Management System in BSE and NSE Margins Exposure Limits Surveillance System in BSE and NSE Circuit Breakers Risk Management System in BSE and NSE The overview of the risk management systems employed by the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE), the two primary stock exchanges in India. It explores the various mechanisms and frameworks implemented to mitigate risks associated with trading, clearing, and settlement, ensuring market integrity and investor protection. The document covers aspects such as margin requirements, surveillance mechanisms, clearing and settlement processes, and the role of regulatory bodies in overseeing risk management practices. Introduction A robust risk management system is crucial for the stability and efficiency of any stock exchange. It safeguards the interests of investors, maintains market integrity, and prevents systemic risks that could destabilize the entire financial system. Both BSE and NSE have implemented comprehensive risk management frameworks that are continuously evolving to address emerging challenges and adapt to changing market dynamics. Key Components of Risk Management Systems The risk management systems in BSE and NSE encompass several key components: 1. Margin Requirements Margin requirements are a fundamental aspect of risk management. They act as a buffer against potential losses arising from adverse price movements. Both exchanges employ various types of margins:
Stock Market Operation Master of Commerce, RCUB. Mr. Mustaq Mulla, SRFGCC, RCU, Belagavi 2 • Initial Margin: This is the minimum amount of funds or securities that a trader must deposit with the broker before initiating a trade. It is calculated based on the volatility of the underlying asset and the size of the position. • Mark-to-Market (MTM) Margin: This margin is calculated daily based on the difference between the trade price and the current market price. If the market moves against the trader, they are required to deposit additional funds to cover the losses. • Extreme Loss Margin: This margin is levied to cover potential losses in extreme market conditions. It is calculated based on historical volatility and stress testing scenarios. • Special Margin: This margin is imposed on specific securities or contracts that are deemed to be particularly risky. 2. Surveillance Mechanisms Surveillance mechanisms are designed to detect and prevent market manipulation, insider trading, and other fraudulent activities. Both BSE and NSE have sophisticated surveillance systems that monitor trading activity in real-time. These systems use algorithms and statistical models to identify unusual patterns and potential violations. • Price and Volume Surveillance: This involves monitoring price and volume movements to detect abnormal fluctuations that could indicate manipulation. • Order Book Surveillance: This involves analyzing order book data to identify suspicious order patterns, such as layering and spoofing. • News Analytics: This involves monitoring news feeds and social media to identify potential sources of market rumors and misinformation. • Insider Trading Detection: This involves analyzing trading activity to identify potential instances of insider trading based on access to unpublished price-sensitive information. 3. Clearing and Settlement Clearing and settlement processes are critical for ensuring the timely and efficient transfer of funds and securities between buyers and sellers. Both BSE and NSE have established clearing corporations that act as central counterparties (CCPs) to guarantee the completion of trades.

Mr. Mustaq Mulla, SRFGCC, RCU, Belagavi 3 • Clearing Corporation: The clearing corporation interposes itself between the buyer and seller, becoming the buyer to every seller and the seller to every buyer. This reduces counterparty risk and ensures that trades are settled even if one party defaults. • Settlement Guarantee Fund: The clearing corporation maintains a settlement guarantee fund, which is used to cover losses in the event of a member default. • Risk-Based Margining: The clearing corporation uses risk-based margining to calculate the margin requirements for its members. This ensures that members with higher risk exposures are required to deposit more collateral. • Delivery versus Payment (DvP): The settlement process follows the DvP principle, which means that securities are only transferred to the buyer when payment is received by the seller. This reduces settlement risk. 4. Risk-Based Supervision Both BSE and NSE employ risk-based supervision to monitor the financial health and operational capabilities of their members. This involves assessing the risk profiles of members and conducting regular audits to ensure compliance with regulatory requirements. • Financial Surveillance: This involves monitoring the financial performance of members to identify potential solvency issues. • Operational Surveillance: This involves assessing the operational capabilities of members to ensure that they have adequate systems and controls in place to manage risks. • Compliance Audits: This involves conducting regular audits to ensure that members are complying with regulatory requirements and exchange rules. 5. Technology Risk Management With increasing reliance on technology, exchanges are exposed to various technology-related risks, including cyberattacks, system failures, and data breaches. BSE and NSE have implemented robust technology risk management frameworks to mitigate these risks. • Cybersecurity Measures: This includes implementing firewalls, intrusion detection systems, and other security measures to protect against cyberattacks. • Business Continuity Planning: This involves developing plans to ensure that critical systems can be restored quickly in the event of a disaster.
Stock Market Operation Master of Commerce, RCUB. Mr. Mustaq Mulla, SRFGCC, RCU, Belagavi 4 • Data Backup and Recovery: This involves regularly backing up data and testing recovery procedures to ensure that data can be restored in the event of a data loss. Regulatory Oversight The Securities and Exchange Board of India (SEBI) is the primary regulator of the Indian securities market. SEBI plays a crucial role in overseeing the risk management practices of BSE and NSE. • Setting Regulatory Standards: SEBI sets regulatory standards for risk management, including margin requirements, surveillance mechanisms, and clearing and settlement processes. • Conducting Inspections: SEBI conducts regular inspections of BSE and NSE to ensure compliance with regulatory requirements. • Enforcing Regulations: SEBI has the power to take enforcement actions against exchanges and their members for violations of regulatory requirements. Challenges and Future Directions Despite the robust risk management systems in place, BSE and NSE face several challenges: • Increasing Market Volatility: Global events and economic uncertainties can lead to increased market volatility, which can strain risk management systems. • Emerging Technologies: New technologies, such as algorithmic trading and high- frequency trading, can introduce new risks that need to be addressed. • Cybersecurity Threats: The increasing sophistication of cyberattacks poses a constant threat to the integrity of the market. To address these challenges, BSE and NSE are continuously evolving their risk management systems by: • Enhancing Surveillance Capabilities: Investing in more sophisticated surveillance technologies to detect and prevent market manipulation. • Strengthening Cybersecurity Measures: Implementing stronger cybersecurity measures to protect against cyberattacks. • Improving Risk Modeling: Developing more sophisticated risk models to better assess and manage risks.

Margins Margins are a crucial aspect of risk management in the stock market. They act as a security deposit to cover potential losses that may arise from trading activities. In essence, they are the amount of money or assets that a trader must deposit with their broker to cover the risk of their positions. Purpose of Margins • Protection against Default: Margins protect brokers and the clearinghouse from losses if a trader defaults on their obligations. • Market Stability: By requiring traders to deposit margins, exchanges reduce the likelihood of excessive speculation and market volatility. • Leverage Control: Margins limit the amount of leverage a trader can use, preventing them from taking on excessive risk. • Investor Protection: Margins help protect investors by ensuring that traders have sufficient funds to cover potential losses. Types of Margins Both BSE and NSE use a multi-layered margin system, which includes various types of margins designed to address different aspects of risk. The key types of margins are: • Initial Margin: This is the minimum margin required to open a trading position. It is calculated as a percentage of the value of the trade and is designed to cover potential losses that may occur before the position can be liquidated. • Maintenance Margin: This is the minimum margin level that must be maintained in the trading account. If the account balance falls below the maintenance margin, the trader will receive a margin call and must deposit additional funds to bring the account back up to the initial margin level. • Mark-to-Market (MTM) Margin: This is the daily adjustment of the margin account to reflect the current market value of the positions. If the value of the positions has decreased, the trader will be required to deposit additional funds to cover the losses.

Mr. Mustaq Mulla, SRFGCC, RCU, Belagavi 6 • Extreme Loss Margin: This margin is levied to cover losses that may occur due to extreme market volatility or unexpected events. • Special/Additional Margin: Exchanges may impose special or additional margins on specific securities or contracts if they are deemed to be particularly risky. Margin Calculation The calculation of margins is complex and depends on several factors, including the volatility of the underlying asset, the size of the position, and the trader's risk profile. Exchanges use sophisticated risk management models to determine the appropriate margin levels for different securities and contracts. The NSE CLEARING uses a SPAN (Standard Portfolio Analysis of Risk) based methodology for calculating margin requirements. SPAN considers various risk factors and scenarios to determine the margin needed to cover potential losses. Margin Calls A margin call occurs when the equity in a trader's account falls below the maintenance margin requirement. When a margin call is issued, the trader must deposit additional funds or liquidate positions to bring the account back up to the initial margin level. If the trader fails to meet the margin call, the broker may liquidate the positions to cover the losses. Exposure Limits Exposure limits are another critical component of risk management in the stock market. They are designed to limit the amount of risk that a trader or broker can take on in the market. Purpose of Exposure Limits • Preventing Over-Leverage: Exposure limits prevent traders and brokers from taking on excessive leverage, which can amplify losses and destabilize the market. • Controlling Systemic Risk: By limiting the exposure of individual participants, exchanges can reduce the risk of systemic failures that could impact the entire market. • Ensuring Orderly Trading: Exposure limits help ensure that trading is conducted in an orderly manner and that no single participant can unduly influence market prices. • Protecting Market Integrity: Exposure limits help protect the integrity of the market by preventing manipulative trading practices. Types of Exposure Limits
Stock Market Operation Master of Commerce, RCUB. Mr. Mustaq Mulla, SRFGCC, RCU, Belagavi 7 • Client-Level Exposure Limits: These limits restrict the maximum exposure that a single client can have in the market. • Broker-Level Exposure Limits: These limits restrict the maximum exposure that a broker can have in the market, based on their net worth and risk management capabilities. • Security-Specific Exposure Limits: These limits restrict the maximum exposure that can be taken in a particular security, based on its liquidity and volatility. Calculation of Exposure Limits Exposure limits are typically calculated as a percentage of the trader's or broker's net worth or available capital. The specific percentage varies depending on the type of security, the trader's risk profile, and the exchange's risk management policies. Monitoring and Enforcement Exchanges closely monitor trading activity to ensure that participants comply with exposure limits. Brokers are required to report their clients' positions and exposures to the exchange on a regular basis. If a trader or broker exceeds their exposure limits, the exchange may take disciplinary action, such as imposing fines or suspending trading privileges. Risk Management Framework Both BSE and NSE have comprehensive risk management frameworks that encompass margins, exposure limits, and other risk mitigation measures. These frameworks are regularly reviewed and updated to reflect changes in market conditions and regulatory requirements. Key Components of the Risk Management Framework • Risk Identification: Identifying potential risks that could impact the market, such as market volatility, counterparty risk, and operational risk. • Risk Assessment: Assessing the likelihood and impact of identified risks. • Risk Mitigation: Implementing measures to reduce or eliminate identified risks, such as margins, exposure limits, and circuit breakers. • Risk Monitoring: Continuously monitoring market activity and risk exposures to ensure that risk mitigation measures are effective.
Stock Market Operation Master of Commerce, RCUB. Mr. Mustaq Mulla, SRFGCC, RCU, Belagavi 8 • Risk Reporting: Reporting risk exposures and incidents to relevant stakeholders, such as regulators and clearing members. Surveillance Systems in BSE and NSE The BSE and NSE employ comprehensive surveillance systems to monitor trading activity, detect anomalies, and prevent market manipulation. These systems utilize a combination of real-time monitoring, data analysis, and automated alerts to identify potential violations of exchange rules and regulations. The primary objectives of these surveillance systems are: • Market Integrity: To ensure fair and transparent trading practices. • Investor Protection: To safeguard investors from unfair trading practices and market manipulation. • Price Discovery: To facilitate efficient and accurate price discovery. • Risk Management: To mitigate systemic risk and maintain market stability. The surveillance systems typically monitor various parameters, including: • Price Movements: Tracking unusual or excessive price fluctuations. • Trading Volumes: Monitoring abnormal trading volumes that may indicate manipulative activity. • Order Patterns: Analyzing order placements and cancellations for suspicious patterns. • Client Activity: Monitoring client trading behavior for potential insider trading or front-running. • News and Rumors: Tracking news and rumors that may impact stock prices. When the surveillance system detects an anomaly, it generates an alert, which is then investigated by the exchange's surveillance team. The team may take various actions, including: • Requesting Information: Requesting information from brokers or traders involved in the suspicious activity. • Issuing Warnings: Issuing warnings to brokers or traders to cease the suspicious activity. • Imposing Penalties: Imposing penalties on brokers or traders found to have violated exchange rules. • Suspending Trading: Suspending trading in a particular stock or by a particular broker.

Mr. Mustaq Mulla, SRFGCC, RCU, Belagavi 9 • Referring Cases to Regulators: Referring cases of serious violations to the Securities and Exchange Board of India (SEBI). Circuit Breakers: A Key Component Circuit breakers are an essential component of the surveillance systems in BSE and NSE. They are automated mechanisms that temporarily halt trading on an exchange or in a specific stock to prevent excessive price volatility. The primary purpose of circuit breakers is to provide a cooling-off period during periods of extreme market fluctuations, allowing investors to reassess the situation and prevent panic selling or buying. Types of Circuit Breakers There are primarily two types of circuit breakers: 1. Market-Wide Circuit Breakers: These circuit breakers halt trading on the entire exchange when a specified market index (e.g., Sensex or Nifty 50) falls below a certain percentage threshold from its previous closing value. 2. Individual Stock Circuit Breakers: These circuit breakers halt trading in a specific stock when its price fluctuates beyond a pre-defined percentage limit during a trading day. Market-Wide Circuit Breakers in India The market-wide circuit breaker system in India is triggered based on the movement of the Nifty 50 and Sensex indices. The thresholds are typically set at 10%, 15%, and 20% declines from the previous day's closing value. The trading halt durations vary depending on the time of day the circuit breaker is triggered: • If the 10% or 15% threshold is breached before 1 PM: Trading is halted for 45 minutes. • If the 10% or 15% threshold is breached between 1 PM and 2:30 PM: Trading is halted for 15 minutes. • If the 10% or 15% threshold is breached after 2:30 PM: Trading is halted for the remainder of the day. • If the 20% threshold is breached at any time during the day: Trading is halted for the remainder of the day.
Stock Market Operation Master of Commerce, RCUB. Mr. Mustaq Mulla, SRFGCC, RCU, Belagavi 10 After the trading halt period, trading resumes with a pre-open session, allowing for price discovery before normal trading resumes. Individual Stock Circuit Breakers in India Individual stock circuit breakers are designed to limit the daily price fluctuation of individual stocks. These circuit breakers are typically set at 2%, 5%, 10%, or 20% depending on the stock's characteristics and liquidity. The exchange determines the applicable circuit breaker limit for each stock. When a stock's price hits the upper or lower circuit limit, trading in that stock is halted for the remainder of the trading day. This prevents further price fluctuations and allows investors to reassess the stock's value. Rationale Behind Circuit Breakers The rationale behind implementing circuit breakers is multifaceted: • Preventing Panic: Circuit breakers help prevent panic selling or buying by providing a cooling-off period for investors to reassess the situation. • Maintaining Orderly Markets: They contribute to maintaining orderly markets by preventing excessive price volatility and ensuring fair trading practices. • Protecting Investors: Circuit breakers protect investors from potential losses due to irrational market behavior. • Reducing Systemic Risk: They help reduce systemic risk by preventing a cascading effect of price declines across the market. Criticism of Circuit Breakers While circuit breakers are generally considered beneficial, they have also faced some criticism: • Interference with Price Discovery: Some argue that circuit breakers interfere with the natural price discovery process by artificially halting trading. • Potential for Manipulation: Critics suggest that circuit breakers could be exploited by manipulators who may try to trigger them to create artificial price movements. • Limited Effectiveness: Some studies have questioned the effectiveness of circuit breakers in preventing market crashes.
