BSE Shares Fall
BSE Share Price: Shares of BSE tumbled 6.2% to an intraday low of Rs 2,500 on the NSE on Wednesday, June 18, after SEBI approved a key change in the derivatives trading schedule. The market regulator has allowed the National Stock Exchange (NSE) to shift its weekly equity derivatives expiry day from Thursday to Tuesday, effective from September 1, 2025.
To prevent a clash in expiry dates between exchanges, SEBI has simultaneously mandated that the BSE shift its Sensex derivatives expiry from Tuesday to Thursday. The decision was communicated via a circular from SEBI, which aims to reduce market volatility and standardize the scheduling of derivative contract expiries.
The changes follow recommendations from SEBI’s Secondary Market Advisory Committee (SMAC), which had reviewed public feedback from a discussion paper issued in March 2025. As per the SEBI directive, BSE will stop launching new weekly index futures contracts from July 1, 2025. Existing contracts will retain their current schedule until expiry, except for long-dated index options which will be adjusted in line with prior realignment practices.
Contracts expiring on or before August 31, 2025, will remain unaffected, while new ones issued thereafter will follow the new expiry structure. Additionally, for non-benchmark index options, index futures, and single-stock derivatives, the minimum contract tenor will now be one month. These will expire on either the last Tuesday or Thursday of the month, based on the chosen schedule of the respective exchange.
Previously, NSE had considered moving its key contracts — including Nifty, Bank Nifty, FinNifty, Nifty Next50, and Nifty Midcap Select — to Monday expiries. However, that plan was shelved after SEBI’s intervention.
Going forward, each exchange will be permitted to offer only one weekly benchmark index options contract on its chosen expiry day. This aims to simplify the derivatives market and remove confusion caused by multiple expiry days across the week.
The realignment raises concerns about how BSE’s derivatives trading volumes and competitive position might be affected, especially given NSE’s dominant market share.
On Tuesday, BSE shares had closed 1.4% lower at Rs 2,660 on the NSE.
