How SPAN Margin and Multi-Leg Hedging Benefits Work in India

Standard Portfolio Analysis of Risk (SPAN) is the sophisticated risk calculation algorithm developed by the Chicago Mercantile Exchange (CME) and adopted by the National Stock Exchange (NSE) to determine total portfolio margin requirements.

Under SEBI’s cross-margining framework, when an option writer hedges their short position by purchasing an out-of-the-money (OTM) wing option, the exchange recognizes the defined-risk profile and grants an immediate margin discount of up to 70%.

What is SPAN margin in Indian F&O trading?
SPAN margin is the minimum mandatory margin required by the clearing corporation to cover potential portfolio losses across 16 extreme market simulation scenarios.

What is Exposure margin in derivatives?
Exposure margin is an additional buffer collected over and above SPAN margin (typically 2% to 5% of notional contract value) to protect against black swan gap openings.

How does option hedging reduce required margin?
When you buy an OTM option to hedge a short position (e.g. Bull Put Spread), your maximum financial loss is capped. NSE grants an immediate margin credit, reducing required margin by up to 70%.

What is the peak margin rule enforced by SEBI?
SEBI requires brokers to collect 100% upfront margin for all intraday and delivery F&O trades based on minimum 4 intraday snapshot checks.

What is the penalty for margin shortfall on NSE?
Shortfall penalties range from 0.5% to 5.0% per day on the deficit amount, depending on the percentage shortfall and frequency of violations.

Can shares be pledged to meet F&O margin requirements?
Yes. Liquid equity shares and mutual fund units can be pledged for margin collateral, subject to exchange haircut rates (typically 15% to 30%).

What is the 50:50 cash-to-collateral rule?
SEBI regulations require that at least 50% of overnight derivative margin must be maintained in cash or cash-equivalents; non-cash collateral cannot exceed 50%.

Why is margin higher for stock futures than index futures?
Individual stocks exhibit higher idiosyncratic volatility and lower liquidity than diversified indices like Nifty 50, resulting in higher SPAN risk parameters.

How does physical settlement impact stock option margins near expiry?
In the final week before expiry, in-the-money (ITM) stock option margin requirements ramp up drastically to ensure full delivery settlement capacity.

How do crypto margin rules compare to Indian SEBI margins?
Crypto derivative exchanges permit up to 20x to 50x isolated leverage without SPAN architecture. Traders can evaluate leverage risks with the Crypto Margin Trading Calculator on Emintage.
