Time of India

The National Stock Exchange (NSE) has revised the expiry day for all index and stock derivatives contracts, shifting it from Thursdays to Tuesdays. This change will come into effect from the end of trading day on August 28 as per a circular.
Currently, weekly Nifty and stock derivative contracts expire every Thursday, while monthly, quarterly, and half-yearly contracts expire on the last Thursday of the relevant expiry month. Starting August 29, all new contracts and existing open positions will reflect Tuesday as the new expiry date.
The change applies across a broad spectrum of contracts: Nifty weekly, monthly, quarterly, and half-yearly contracts. Bank Nifty and other indices like Fin Nifty, Midcap Nifty, Nifty Next50 and all single stock derivatives.
For example, a Nifty weekly contract originally expiring on September 4 will now expire on September 9. Similarly, the monthly Nifty contract scheduled to expire on September 25 will move to September 30. The change has been illustrated in an annexure provided by the NSE to reduce operational confusion.
The revised contract files, reflecting the new expiry dates, will be available on the NSE on August 28 after market hours. Members have been advised to use updated versions of contracts.
There are no other changes to the contract specifications beyond the expiry day shift. The clearing corporations will separately communicate any adjustments to the settlement schedules.
The change, which aligns NSE more closely with global practices in some markets, is aimed at operational streamlining and risk reduction—though market participants will need to update trading systems and adjust internal processes accordingly.
