This move is part of a broader effort to streamline expiry days across exchanges and reduce volatility. The new expiry schedule will come into effect from September 1, 2025.

The Bombay Stock Exchange (BSE) has also been given the go-ahead to continue with Thursday as its expiry day from Tuesday.

The exchange had proposed Thursday as its preferred settlement day, and SEBI has accepted the suggestion.

Both exchanges shared official circulars outlining the changes following SEBI's directive issued in May.

According to the circular issued by NSE, all existing contracts will continue to have Thursday as the expiry day, except for long-dated index options, which may be realigned in line with previous practices.

For new contracts, those expiring on or before August 31, 2025, will also follow the current Thursday expiry.

From September 1, 2025, however, expiry will shift to Tuesday, with monthly contracts expiring on the last Tuesday of each month.

Meanwhile, BSE’s circular mirrors a similar structure. All existing contracts will maintain their current expiry schedule, with long-term index options adjusted where necessary.

New contracts expiring on or before August 31, 2025, will keep the Tuesday expiry. From September 1, 2025, BSE’s expiry day will officially move to Thursday.

The exchange also announced that it will stop introducing fresh weekly index futures contracts starting July 1.

These decisions were taken after detailed discussions in SEBI’s Secondary Market Advisory Committee (SMAC) to bring consistency in expiry days and ensure smooth transitions between the exchanges.

The change is also expected to reduce excessive speculation and help exchanges focus on building sustainable trading patterns.

With this development, NSE aims to regain some market share in derivatives trading, where BSE had made notable progress after launching contracts with a different expiry day.

Derivatives contribute significantly to revenue for both exchanges, and a clear distinction in expiry schedules could play a crucial role in shaping future volumes.

Finally some clarity in expiry days! This will help reduce confusion for retail traders like me who trade on both exchanges. Though 2025 seems too far - why not implement it sooner? 🤔

Good move by SEBI to standardize expiry days. But I hope brokers update their systems properly - last time there was a change, my trading platform showed wrong expiry dates for weeks!

As someone who trades F&O regularly, I'm concerned about the long transition period. Market participants need time to adjust, but 15 months seems excessive. Could create unnecessary confusion in the interim.

Interesting to see NSE choosing Tuesday while BSE sticks with Thursday. This differentiation might actually help both exchanges carve their own niches in derivatives trading. Smart competitive strategy!

Reducing volatility is good, but will this really work? Our markets are influenced more by global factors than expiry days. Still, any step towards stability is welcome 👍

Hope SEBI monitors the implementation closely. In past, such changes have led to technical glitches and settlement issues. Retail investors often bear the brunt of these transition problems.
