NSE and BSE to Realign Derivatives Expiry Days after Sebi's Approval

The National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE) will change their equity derivatives expiry days following approval from the Securities and Exchange Board of India (Sebi). NSE's expiry day will be Tuesday and BSE's will be Thursday, effective for contracts expiring after September 1, 2025.

The National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE) are set to implement new expiry days for equity derivatives, following approval from the Securities and Exchange Board of India (Sebi). Starting September 1, 2025, NSE will conduct expiries on Tuesdays while BSE will conduct them on Thursdays.

This shift marks a deviation from their current schedules, where NSE expiries occur on Thursdays and BSE on Tuesdays. Both exchanges have been granted approval for their respective schedules, aiming to create a uniform gap between expiries and prevent them from falling on the week's first or last day.

Current contracts expiring before the effective date will maintain their original schedules, except for long-dated index options, which will be realigned. The exchanges will issue detailed circulars with guidelines to ensure a seamless transition, as part of Sebi's directives to standardize equity derivatives expiries across all exchanges.
