The National Stock Exchange of India (NSE India) has announced a major change in the expiry cycle of Nifty Bank's F&O contracts. Starting from July 7, 2023, the expiry day for Nifty Bank contracts will be shifted from Thursday to Friday. This adjustment aims to provide traders with more time to analyze market conditions, manage risks effectively, and reduce weekend risks. The first Friday expiry under the new system will occur on July 14, 2023. This change aligns with the recent decision by the Bombay Stock Exchange (BSE) to introduce Friday as the expiry day for weekly options contracts in the Sensex and Bankex contracts.
