NSE announces change in weekly F&O expiry day

The National Stock Exchange (NSE) announced on Tuesday that it will change the expiry date for all Nifty index weekly derivatives contracts. Effective April 4, the expiry day for Nifty weekly Futures & Options (F&O) contracts will move from Thursday to Monday of the expiry week.

This shift will also apply to Nifty monthly, quarterly, and half-yearly F&O contracts, which will now expire on the last Monday of the expiry month instead of the last Thursday.

Additionally, the expiry date for Bank Nifty, FinNifty, Nifty Midcap Select, and Nifty Next50 F&O contracts will also be revised to the last Monday of the expiry month starting April 4.

The change will take effect from April 4, 2025, with all existing contracts being revised to the new expiry day on April 3, 2025 (End of Day). This shift in expiry day aims to standardise and streamline the process for market participants.

In financial markets, derivatives typically include forward contracts, futures, options, or other hybrid contracts that are linked to a real asset or a securities index.

Futures contracts involve a legally binding agreement to buy or sell an underlying security at a predetermined date, while options provide the right (but not the obligation) to buy or sell the asset at a fixed price during a specified period.
