NIFTY50 contracts to expire on Tuesdays; SENSEX contracts will settle on Thursdays: Report

Meanwhile, BSE SENSEX derivative contracts will now get settled on Thursday instead of Tuesday.

The move comes after SEBI’s regulatory overhaul of the equity derivatives segment announced last month. As per the new rules, all exchanges must align weekly index derivatives expiries to either a Tuesday or a Thursday, removing the earlier flexibility where each exchange could set its own expiry day.

The new framework is aimed at reducing concentration risks and minimising volatility due to multiple expiry events occurring across the week, SEBI said last month.

As part of the transition process, SEBI has directed that no fresh weekly index futures contracts should be introduced from July 1, 2025, to ensure a smooth migration to the revised expiry cycle. The regulator also added that any changes in expiry days by exchanges must be pre-approved by SEBI.

The exchanges were asked to submit their preferred expiry day to SEBI by June 15, 2025. NSE opted for Tuesday, while BSE proposed Thursday, both of which have now received SEBI’s go-ahead.

This marks a shift from the previous practice where expiry days were largely exchange-determined. SEBI’s new rules are designed to bring uniformity and stability to the derivatives market, enhance operational efficiency, and protect investor interest by avoiding crowding of expiries on overlapping days, analysts said.

New expiry days will come into effect from September 1.
