The National Stock Exchange (NSE) has received capital market regulator Sebi’s nod for Tuesday as its expiry day, according to a company filing on June 16, 2025 while BSE has confirmed that its expiry day proposal for Thursday has been accepted.
The communication from the regulator has been conveyed to both the exchanges.
The shift of NSE’s expiry day from Thursday to Tuesday is expected to help the exchange regain market share from rival BSE. Derivatives trading makes up a large part of the revenue for both stock exchanges. NSE handles the highest number of derivatives contracts globally, and was reportedly seeking to change its expiry date to Tuesday from Thursday, in an effort to reclaim market share from BSE at a time when the regulator has been nudging both exchanges to curb excessive trading.
