The Big Jump
On March 28, 2025, shares of Bombay Stock Exchange (BSE) Ltd surged 11%, hitting a high of ₹5,232.80. The rally came after the National Stock Exchange (NSE) decided to postpone its plan to shift the weekly expiry day for derivatives from Thursday to Monday.
This sudden spike gave BSE a temporary advantage in the equity derivatives market, where it has been steadily gaining ground against NSE.

Why Did NSE Delay Its Plan?
The NSE’s decision followed a consultation paper by SEBI, India’s market regulator. SEBI proposed that all exchanges should have uniform expiry days—either Tuesday or Thursday—to reduce market volatility.
Additionally, SEBI suggested that exchanges must now seek approval before changing expiry schedules. This move aims to bring more stability to the derivatives market.
For now, NSE’s delay means BSE can continue competing on a level playing field, at least for the time being.
What’s Next for BSE?
While this is a short-term win, BSE’s long-term growth looks promising. Over the past year, its stock has delivered an 86% return, showing strong investor confidence.
Prominent investors like Mukul Mahavir Agrawal and S Gopalakrishnan continue to hold significant stakes, reinforcing faith in BSE’s potential.
The Bigger Picture
BSE, Asia’s oldest stock exchange, remains a key player in India’s financial markets. With offerings in equities, derivatives, and SME platforms, it plays a crucial role in shaping the country’s capital markets.
For now, traders and investors are watching closely—will NSE’s next move tilt the scales again?
