📌 Introduction

The Securities and Exchange Board of India (SEBI) has consistently played a pivotal role in ensuring transparency, investor protection, and systemic stability in the Indian  securities market. One of the latest regulatory interventions is the expansion of margin requirements for derivatives, aimed at enhancing market discipline and reducing  systemic risk.

With the rise in speculative trading and leveraged positions in derivative segments, the new margin framework intends to tighten risk management practices among  brokers, traders, and institutions. This article explains the expanded margin framework, its rationale, implications, technical aspects, and stakeholder responses.

📘 What Are Derivatives?

🔄 Definition

A derivative is a financial contract whose value is derived from the performance of an underlying asset such as stocks, commodities, currencies, interest rates, or market indexes.

 Types of Derivatives

• Futures Contracts

• Options Contracts

• Swaps

• Forward Contracts

📈 Purpose of Derivatives

• Hedging risks

• Speculation

• Arbitrage opportunities

• Portfolio diversification

🏦 SEBI’s Role in Derivatives Regulation

SEBI is responsible for regulating the Indian capital markets, which includes ensuring orderly development and maintenance of the derivatives segment. The derivatives market has grown exponentially over the years, both in terms of volumes and number of participants.

• Margining systems

• Position limits

• Risk disclosures

• Market surveillance

📜 Previous Margin Framework

📊 Initial and Maintenance Margins

Before the recent reforms, the margin system for derivatives mainly included:

1. Initial Margin: Required upfront for entering into a trade.

2. Maintenance Margin: Minimum account balance to keep a position open.

3. SPAN Margining: Based on the Standard Portfolio Analysis of Risk model developed by CME.

⚠️ Peak Margin Rules (Phased from 2020)

SEBI had earlier introduced peak margin rules to curb excessive leverage by ensuring collection of intraday margins.

🚨 Why SEBI Expanded Margin Requirements? 

🔎 Key Observations

1. 
   High Volatility: Sharp movements in stock prices and derivatives led to margin shortfalls.

2. Leveraged Trading Risks: Traders were taking large positions with inadequate capital.

3. Brokers' Credit Exposure: Default risk was rising for brokers offering high leverage.

4. Retail Participation Surge: Influx of new, inexperienced retail investors necessitated stronger safeguards.

📢 SEBI's Statement

“To strengthen the risk management framework and align with global best practices, SEBI proposes enhancement of margin requirements in the derivatives segment.”

 Key Components of the Expanded Margin Framework

1️⃣ Portfolio-Based Margining

🔹 Concept: Instead of applying margin on individual positions, a holistic approach is adopted to calculate margin on the entire portfolio of positions considering correlations and offsetting risks.

🔹 Advantage: More accurate risk assessment and optimized margin requirements.

2️⃣ Introduction of Cross-Margining Across Segments

🔸 What Is Cross-Margining?
Allows offsetting of margin requirements between cash and derivatives or across related positions like equity and index futures.

🔸 Benefit:
Reduces the total margin requirement and enhances liquidity without increasing systemic risk.

3️⃣ Enhanced Margin Requirements for Short Options 

🔺 New Rule:
Mandatory higher margin for uncovered (naked) short option positions.

🔺 Example:
Shorting Nifty calls without holding the underlying will now attract additional margin buffers.

4️⃣ Volatility-Based Margin Adjustments

📉 Margins will now be dynamically adjusted based on real-time volatility indices like India VIX.

🔸 In high-volatility periods → Higher margins
🔸 In stable periods → Lower margins

5️⃣ Peak Margin Requirements Retained and Enhanced

📌 Continuation of Intraday Peak Margin Monitoring, now expanded to include more checkpoints.

🕐 Brokers must collect the highest margin obligation intraday and not just the End-of-Day (EOD) margin.

6️⃣ Changes in Margin Collection Compliance

✅ SEBI has mandated 100% upfront margin collection before trade execution.

✅ Penalties for non-compliance will be more stringent, and repeated breaches may result in regulatory action.
