On March 28, 2025, BSE shares leaped approximately 18% after the Securities and Exchange Board of India (SEBI) proposed limiting equity derivatives expiries to either Tuesday or Thursday. The move is designed to protect BSE’s market share by retaining Tuesday as its benchmark expiry day, especially as NSE holds Thursday.
Analysts have noted that this strategy could help BSE boost its options trading market share to over 25-30% by the second quarter of FY2026, compared to its current 18-19% share. Additionally, the proposal led NSE to abandon its plan to shift its expiry day to Monday, underlining the potential for increased trading activity and revenue for BSE in the evolving market landscape.
