Following the scrapping of weekly contracts of Nifty Bank, FinNifty, Nifty Midcap Select and Nifty Next50, the National Stock Exchange (NSE) has changed the monthly expiry days of all the 4 F&O contracts to Thursday with effect from January 1.
Under the current set-up, Nifty Bank monthly and quarterly contracts expire on the last Wednesday of the month while for Fin Nifty it is Tuesday. Nifty Midcap Select contracts expire on Mondays and Nifty Next50 on Fridays.
"There is no change in expiry day for Nifty monthly, weekly, quarterly & half yearly contracts. The circular shall come into effect from EOD of January 01, 2025 i.e. Expiry day for all existing contracts will be revised to “New Expiry Day” on January 01, 2025 (EOD)," NSE said in a circular.
Revised expiry date of all existing index derivatives contracts shall be available in the contract file which shall be generated on January 1, 2025 end of the day which shall be applicable for trading on January 2,2025, the bourse said.
Earlier in the week, BSE shifted the monthly expiries of Sensex, Bankex and Sensex50 to last Tuesday of every month from January 1, 2025. The weekly contracts of Sensex will also expire on Tuesday as against the existing Friday expiry.
With effect from November 20, both BSE and NSE have discontinued weekly options contracts of all index derivative products barring those of Sensex and Nifty.
To solve the problem of excessive trading in index derivatives on expiry day, Sebi asked bourses to choose one index derivative product each for weekly expiry contracts.
