Indian derivatives expiry settlements will return to a pricing method based on the final 30 minutes of continuous trading from December 7, 2026, under a Securities and Exchange Board of India decision announced on October 15. Brokers expect the reversal to make settlement prices more predictable after a closing-auction system introduced in August disrupted trading strategies, although a recovery in volumes remains uncertain.
Key Takeaways
- SEBI will restore continuous-trading VWAP as the basis for expiry-day derivatives settlement from December 7.
- Derivatives activity weakened sharply in August before a slight recovery in September.
- Brokers expect clearer settlement pricing to help traders manage expiry risk, but higher volumes are not assured.

What changes for Indian derivatives settlement
SEBI's October 15 circular revises the settlement methodology for expiring derivatives contracts. Stock derivatives will use the underlying share's volume-weighted average price, or VWAP, during the final 30 minutes of continuous trading. Index derivatives will use an index value calculated from constituent stocks' VWAPs.
The decision reverses a key settlement feature of the closing auction session introduced on August 3. It is a change to how expiry settlement prices are calculated, rather than an abandonment of SEBI's broader effort to curb speculative trading.
For traders holding positions into expiry, the practical distinction is the pricing window: settlement will again reflect transactions across the final half-hour of continuous trading rather than depend on the closing auction.

Trading activity has only begun to recover
In August, average daily equity-derivatives turnover on the National Stock Exchange of India fell to an 18-month low. Turnover on the smaller BSE declined by one-third, before activity rebounded slightly in September.
Dhiraj Relli, managing director of HDFC Securities, said greater clarity around expiry settlement prices should help restore confidence and could bring volumes closer to levels seen before the closing auction system over time. That is an expectation, not a confirmed result of a rule change that has yet to take effect.
Why brokers and trading desks are watching
Eshaan Lazarus, founder and chief executive of 021 Trade, said lower liquidity in the closing auction had allowed participants with relatively small books to influence closing prices, particularly in thinly traded instruments. He expects a return to VWAP to reduce the scope for those swings.
More predictable settlement pricing could make expiry-risk management and cash-versus-derivatives arbitrage easier to execute. Jefferies analysts also said the change could benefit brokers whose order volumes remain below pre-auction levels. Any resulting increase in transaction revenue for brokers and exchanges would depend on traders actually returning.
Conclusion
The next confirmed milestone is implementation on December 7. The subsequent test will be whether more predictable expiry pricing translates into a sustained recovery in trading activity.
