Stock exchanges needed approval from SEBI before making any changes to expiry days. It will help in creating predictability in the market and reduce constant re-shuffling of expiry days.NSE has received approval from the market reguator SEBI to shift its equity derivatives contract expiries to Tuesdays from Thursdays. Peer Bombay Stock Exchange has also confirmed that it has been assigned Thursday expiry, as sought by the exchange, against Tuesday at present. The Metropolitan Stock Exchange, on the other hand, is said to have received nod for Tuesday as its expiry, whenever it decides to launch its derivative expiry contracts.
In a circular, NSE said SEBI has agreed to the expiry day proposed by NSE i.e. Tuesday. NSE said it would keep the expiry day of derivatives contracts unchanged for already introduced contracts - with the exception of long dated index options contracts for which equity exchanges would suitably realign expiry day. NSE said it would continue with present expiry day (Thursday) for derivative contracts which expire on or before August 31, 2025, but will change the expiry day of the derivatives contracts which expire on or after September 01, 2025 to Tuesday.
