Various risks faced by the participants in derivatives
This sub‑topic explores the various risks that participants in equity derivatives face, why understanding them is crucial for the NISM exam, and how they integrate with the broader fundamentals of derivatives. Recognising each risk type helps you answer scenario‑based questions and avoid common pitfalls. The content aligns with SEBI regulations and the NISM Series VIII syllabus.

Classification of Risks in Equity Derivatives
Market risk (also called price or directional risk) arises when the underlying equity price moves adversely to the position held. In futures and options, the magnitude of loss depends on the contract’s delta and the volatility of the underlying security. For the exam, remember that market risk is the most frequently tested risk because it directly influences profit and loss.
Liquidity risk occurs when a participant cannot unwind a position at a reasonable price due to thin trading volumes or wide bid‑ask spreads. In Indian exchanges, the NIFTY and BANKNIFTY contracts are highly liquid, but exotic or less‑traded stocks may exhibit significant liquidity gaps, which can lead to slippage.
Credit (counter‑party) risk is the possibility that the opposite party – typically a broker or clearing member – fails to meet its settlement obligations. SEBI mandates margin requirements and the use of a central clearing house (NSE/ BSE) to mitigate this risk, but residual credit exposure remains, especially in over‑the‑counter (OTC) derivative transactions.
- Exam focus: differentiate between market‑driven losses and losses caused by a counter‑party default.
- Remember: margin is a safeguard, not a guarantee against credit risk.
Students often attribute a loss caused by a counter‑party default to market risk. The correct approach is to label it as credit risk and highlight the role of margin and clearing houses.
Market (Price) Risk
Market risk reflects the sensitivity of a derivative’s value to changes in the underlying equity price. The key metric is the delta, which measures the first‑order price change. A high‑delta position (e.g., an ATM call option) will experience larger profit or loss for a given move in the underlying.
Volatility amplifies market risk. SEBI’s volatility‑based margin system adjusts required margins according to the implied volatility of the contract, ensuring that participants hold sufficient capital during turbulent periods.
Exam relevance: Questions may ask you to identify the primary risk in a scenario where the underlying index drops sharply, or to calculate the impact of a delta change on a position’s profit‑and‑loss.
Liquidity Risk
Liquidity risk emerges when the market depth is insufficient to execute large orders without moving the price. In Indian futures, the contract size (e.g., 75 shares for NIFTY) and the presence of market makers usually reduce this risk, but during earnings announcements or macro events, spreads can widen dramatically.
For options, especially out‑of‑the‑money strikes, low open interest can cause a trader to accept a price far from the theoretical value when exiting. This slippage directly erodes returns and may trigger a margin call.
Exam tip: When a question mentions “wide bid‑ask spread” or “inability to close the position,” the correct answer points to liquidity risk, not market risk.
Credit (Counter‑Party) Risk
Credit risk is the chance that the broker, clearing member, or OTC counterpart fails to fulfil its settlement obligation. SEBI requires all exchange‑traded derivatives to be cleared through a central counter‑party (CCP), which interposes itself between buyer and seller, thereby reducing bilateral exposure.
Despite the CCP, residual credit risk exists in the form of margin defaults. If a participant’s margin balance falls below the maintenance margin, the clearing house may liquidate positions, but extreme market moves can still cause losses that exceed posted margins.
In the exam, you may be asked to identify the regulatory tool that mitigates credit risk – the answer is the mandatory use of a clearing house and daily mark‑to‑market settlement.
Do not confuse the purpose of margin (to cover market risk) with credit risk mitigation (clearing house guarantee). Both are required, but they address different exposures.
Operational Risk
Operational risk stems from failures in processes, systems, or human error. In derivatives, this includes incorrect order entry, settlement mismatches, or technology outages on the exchange platform.
SEBI’s circulars mandate robust back‑office reconciliation and real‑time monitoring to limit such risks. Brokers must maintain audit trails and have disaster‑recovery plans for their trading systems.
Exam focus: A scenario describing a failed trade due to a system glitch will test your knowledge of operational risk and the importance of reconciliation procedures.
Legal & Regulatory Risk
Legal risk involves non‑compliance with SEBI regulations, contract specifications, or tax provisions. For example, violating position limits or failing to disclose large exposures can attract penalties.
Regulatory risk also covers changes in policy, such as adjustments to margin requirements or the introduction of new contract specifications, which can affect profitability.
Exam tip: Questions may ask which authority governs derivatives in India – the answer is SEBI, and they may probe your awareness of key circulars like the “Margin Framework for Futures & Options.”
Systemic Risk
Systemic risk refers to the possibility that a shock in the derivatives market spreads to the broader financial system. The 2008 crisis highlighted how large, leveraged positions can create contagion.
In India, SEBI’s market‑wide circuit breakers and the presence of a single CCP (NSE Clearing Ltd.) are designed to contain systemic fallout. However, extreme volatility can still trigger margin squeezes across many participants.
For the exam, recognise that systemic risk is an overarching concern that influences regulatory safeguards, not a risk specific to an individual trader’s position.
Summary of Major Risks in Equity Derivatives
| Risk Type | Definition | Primary Impact | Common Mitigation |
|---|---|---|---|
| Market Risk | Adverse price movement of underlying | Profit/Loss volatility | Delta hedging, stop‑loss orders |
| Liquidity Risk | Inability to exit position at desired price | Slippage, higher transaction cost | Trade in high‑volume contracts, monitor depth |
| Credit Risk | Counter‑party default on settlement | Potential loss beyond margin | Use of clearing house, daily MTM, adequate margin |
| Operational Risk | Process or system failure | Erroneous trades, settlement delays | Robust back‑office, audit trails |
| Legal/Regulatory Risk | Non‑compliance with SEBI rules | Fines, contract invalidation | Adherence to circulars, position limits |
| Systemic Risk | Market shock affecting whole system | Broad market disruption | Circuit breakers, macro‑monitoring |
Where:
F_{close}= Futures price at the time of closing (₹)F_{entry}= Futures price at entry (₹)Q= Contract size (number of shares per lot)Worked Example
Given F_{entry}=15,000 ₹, F_{close}=15,500 ₹, Q=75 shares: Step 1: MTM = (15,500 - 15,000) × 75 Step 2: MTM = 500 × 75 Step 3: MTM = 37,500 ₹ Verification: (15,500 - 15,000) × 75 = 37,500.
Typical Risk Exposure Distribution for an Indian Derivatives Trader
Scenario
Rohit holds 2 NIFTY futures contracts bought at 15,200 ₹ each (lot size 75). The market falls to 14,800 ₹. His maintenance margin is 5% of the contract value. Calculate the MTM loss and determine if a margin call occurs.
Solution
Initial contract value = 15,200 × 75 = 1,140,000 ₹ per contract. For 2 contracts, total exposure = 2,280,000 ₹. MTM loss per contract = (14,800 - 15,200) × 75 = (-400) × 75 = -30,000 ₹. Total loss = -60,000 ₹. Maintenance margin = 5% × 2,280,000 = 114,000 ₹. Assuming Rohit had posted the initial margin of 150,000 ₹, his remaining margin after loss = 150,000 - 60,000 = 90,000 ₹, which is below the maintenance requirement, so a margin call is triggered.
Conclusion
The scenario illustrates how market risk directly leads to a margin shortfall, emphasizing the need for adequate capital buffers.
Remember Market, Liquidity, Credit, Operational, Legal, Systemic – "MLC OLS" – to quickly list all risk types.
Risk Mitigation Techniques
Effective mitigation begins with proper position sizing and the use of stop‑loss orders to cap market risk. Diversifying across different underlying indices (e.g., NIFTY and BANKNIFTY) reduces concentration.
Utilising the clearing house’s margin system and maintaining a buffer above the maintenance margin safeguards against credit risk. For OTC contracts, bilateral collateral agreements are essential.
Liquidity risk can be managed by trading contracts with high open interest and monitoring the bid‑ask spread before entering large positions. Operational risk is reduced through automated order routing, regular reconciliations, and adherence to SEBI’s audit requirements.
Legal risk is mitigated by staying updated with SEBI circulars, ensuring contract specifications match exchange rules, and maintaining proper documentation for tax reporting.
⭐Exam Takeaways
- Market risk is driven by price movement and delta; it is the most frequently tested risk.
- Liquidity risk arises from thin trading and wide spreads; high open interest contracts help mitigate it.
- Credit risk is counter‑party default; SEBI‑mandated clearing houses and daily MTM reduce exposure.
- Operational risk covers system failures and human errors; robust back‑office controls are essential.
- Legal/regulatory risk involves non‑compliance with SEBI rules; stay current with circulars.
- Systemic risk affects the entire market; circuit breakers and margin frameworks are systemic safeguards.
- Mark‑to‑Market formula calculates daily profit/loss and triggers margin calls when losses exceed posted margin.
- Use the mnemonic “MLC OLS” to recall all six risk categories quickly during the exam.
