Wed Mar 05 04:10:00 UTC 2025: ## BSE Shares Plunge After NSE Shifts F&O Expiry Day to Monday

**Mumbai, India** – Shares of the Bombay Stock Exchange (BSE) plummeted over nine percent on Monday after its rival, the National Stock Exchange of India (NSE), announced a shift in the expiry day for all futures and options (F&O) contracts. Effective April 4th, 2025, all Nifty and related index F&O contracts will expire on the last Monday of the month, instead of Thursday.

The NSE cited geopolitical factors and increased efficiency as reasons for the change. A spokesperson stated that the move aims to account for weekend events and provide a better trading environment on Monday. Experts suggest the shift could lead to increased Friday activity as traders square off positions before the weekend. Some analysts also believe this is a strategic move by NSE to regain market share in the options segment.

The BSE, already facing headwinds from potential regulatory changes impacting proprietary traders (Goldman Sachs recently lowered its target price for BSE shares due to this), saw its shares fall to a four-month low following the NSE’s announcement. The NSE’s decision also affects Bank Nifty, FinNifty, Nifty Midcap Select, and Nifty Next50 contracts.

NSE Chief Business Development Officer Sriram Krishnan stated the change is partially intended to curb speculation and improve investor awareness of options trading risks. He suggested a single weekly expiry day for all exchanges could be the ultimate solution. However, the market reacted negatively to the immediate impact on BSE’s trading volume, highlighting the interconnectedness and competition within India’s stock market.
