SEBI Notifies Strict Six-Point Overhaul to Regulate Equity Index Derivatives

The Securities and Exchange Board of India (SEBI) has officially notified a sweeping six-measure regulatory framework designed to curb hyperactive speculative trading in index derivatives. The aggressive intervention addresses escalating concerns over retail wealth destruction, following regulatory studies showing that over 90 percent of individual options traders sustained substantial net losses.

Under the new directives, the minimum trading contract size for equity index derivatives will be raised from the existing range of ₹5 lakh to ₹10 lakh up to ₹15 lakh at inception, with a subsequent band permitting adjustments between ₹15 lakh and ₹20 lakh. This significant capital barrier aims to discourage inexperienced retail participants from excessive leverage.

Regulatory Overhaul Targets Rampant Retail Speculation in Futures and Options

In a decisive structural change, SEBI has also rationalized weekly index derivative contracts. Each stock exchange will be permitted to offer weekly expiry contracts for only one benchmark index rather than multiple sectoral or broad indices, effectively ending the daily cycle of speculative expiries across the National Stock Exchange and BSE.

Brokers will now be strictly required to collect option premiums upfront from retail buyers. Previously, intraday margin flexibilities allowed traders to take outsized positions without committing sufficient cash, leading to sudden collateral shortfalls during volatile market swings.

Higher Capital Thresholds and Margin Upfronting Transform Market Dynamics

The regulator also introduced an additional extreme loss margin of 2 percent on option write positions on expiry day, alongside the removal of calendar spread margin benefits on expiring contracts. These operational constraints will significantly raise the cost of speculative intraday hedging.

The phased implementation of the new rules will commence on November 20, 2024, continuing into February 2025. While domestic retail participation is expected to decline in the near term, institutional analysts believe the framework will foster a healthier and more sustainable capital market ecosystem.
