Shares of BSE skyrocketed 15.33% to an intraday high of Rs 5,387 after the National Stock Exchange (NSE) decided to defer its plan to shift the weekly expiry day for

The move, which was earlier scheduled to take effect from April 4, has now been put on hold following a consultation paper released by the Securities and Exchange Board of India (SEBI).

The market regulator has proposed that expiry days for equity derivatives be uniform across exchanges and be limited to either Tuesday or Thursday, aiming to reduce volatility and ensure better predictability for traders.

SEBI has also suggested that exchanges seek prior approval before implementing any such changes in expiry schedules.

This deferment may be seen as a positive development for BSE, which has been steadily increasing its market share in the equity derivatives segment. With NSE’s proposed change now delayed, BSE may benefit from a continued level playing field, at least in the near term, especially as market participants wait for further clarity on SEBI’s final decision.


SEBI's proposal follows NSE's move to shift the F&O expiry day for indices like Nifty, Bank Nifty, FinNifty, Nifty Next50, and Nifty Midcap Select from the current Thursday to Monday. The change was announced in a circular issued on March 4 and was scheduled to take effect from Tuesday, April 4, 2025.

Apart from benchmark index options, all other equity derivative contracts, including benchmark index futures, non-benchmark index futures, and options, as well as all single stock futures and options, will be offered with a minimum tenure of one month. These contracts will expire in the last week of each month on their designated expiry day.
