The National Stock Exchange (NSE) on Tuesday decided to change the expiry of all contracts to Monday from Thursday in its equity derivatives segment from April 4.
In a circular, the premier F&O bourse said, Nifty weekly contracts, Nifty monthly, quarterly and half-yearly contracts, Bank Nifty monthly and quarterly contracts and Fin Nifty, MidCap Nifty and Nifty Next 50 monthly contracts would be expired on Monday. All single stock futures will also expire on Monday, the circular added.
Revised expiry date of all existing derivatives contracts will be available in the contract file generated on April 3 to avoid operational complexities, NSE said.
Settlement schedule
“There is no other change in the contract specifications of index and stock derivatives,” NSE said, The settlement schedule will be intimated separately by Clearing Corporations.
It may be recalled that NSE had revised the expiry dates to Thursday for index derivative contracts, effective January 1, 2025 after the BSE made a similar change to its derivative contracts’ expiry dates to Tuesday from January 1.
According to NSE latest market pulse, the exchange commandes 99.9 per cent market share in equity futures and 85.1 per cent in equity options.
Last week, the SEBI proposed to replace the current notional terms approach for computing open interest (OI) in equity derivatives, with a future-equivalent or delta-based approach — aimed at curbing volatility in the derivatives segment. Earlier, SEBI had asked exchanges to trade only in one index weekly series and increased the contract size to ₹15 lakh from ₹5-10 lakh.
SEBI’s measures were aimed at curbing the exuberance in derivatives trading because of the heavy losses incurred by individual investors.
Already, trading activity across the industry has been subdued both in cash and options volumes due to SEBI measures and steep ongoing correction.
