MUMBAI — The Securities and Exchange Board of India (SEBI) has formally operationalized its comprehensive six-point regulatory framework governing equity index derivatives (Futures & Options). The decisive policy intervention follows extensive consultative studies conducted by the capital markets regulator, which demonstrated that explosive growth in speculative short-dated option trading was causing severe financial harm to retail household investors while diverting capital away from productive capital formation.
The revised measures fundamentally alter trading ergonomics across the National Stock Exchange (NSE) and Bombay Stock Exchange (BSE), curbing hyper-speculation on expiry days and reinforcing systemic risk buffers across clearing corporations.
The Six Structural Regulatory Pillars
SEBI’s policy overhaul recalibrates contract architecture, leverage structures, and exchange operational rules across multiple dimensions:
- Upward Revision of Minimum Contract Value: The minimum contract size for index derivatives has been escalated from ₹5 lakh to ₹15 lakh at inception, scaling toward ₹20 lakh based on quarterly index valuations, directly filtering out ultra-small speculative accounts.
- Rationalization of Weekly Index Expiries: Stock exchanges are restricted to providing weekly derivatives contracts for only one benchmark index per exchange (NSE retains Nifty 50; BSE retains Sensex), putting an end to daily expiry gambling cycles.
- Mandatory Upfront Option Premium Collection: Trading members are legally mandated to collect upfront premiums from retail options buyers, preventing brokers from extending unauthorized intraday margins.
- Removal of Calendar Spread Benefit on Expiry Day: Margin offsets on offsetting calendar spread positions are disabled for contracts expiring on the same trading day due to heightened basis risk during final settlement.
- Intraday Position Limit Monitoring: Clearing corporations deploy real-time intraday position limit snapshots to ensure institutional high-frequency trading (HFT) firms do not breach market concentration thresholds during expiry hours.

Empirical Rationale: Protecting Household Balance Sheets
The regulatory intervention was anchored in rigorous data. A landmark analytical report published by SEBI revealed that out of approximately 1 crore individual retail F&O traders active during the preceding three fiscal years, 93% suffered net losses, with the average loss per trader exceeding ₹2 lakh after accounting for transaction fees and brokerage charges.
By dampening speculative frenzy, SEBI aims to redirect domestic household savings toward long-term systematic investment plans (SIPs), sovereign green bonds, and productive equity offerings that support sustainable economic growth.
