BSE Derivatives Segment Sees Unprecedented Growth
The futures and options (F&O) segment of the Bombay Stock Exchange (BSE) has experienced an extraordinary surge, with its average daily premium turnover growing by a remarkable 1,539% over the last two years. This significant expansion has occurred despite a regulatory environment shaped by several restrictive measures from the Securities and Exchange Board of India (Sebi).
Financial Performance and Market Share Gains
BSE's average daily premium turnover stood at ₹15,325 crore as of last Tuesday, marking an impressive 112% increase from the end of 2024. This growth trajectory contrasts sharply with the National Stock Exchange (NSE), whose average daily premium turnover has fallen by 24.3% from its peak. Experts attribute BSE's robust performance primarily to market-share gains and the successful onboarding of new clients, rather than an overall industry volume expansion.
Key Drivers of Growth
Mohit Mangal, vice president of research at Centrum, explained that BSE benefited significantly from the strategic positioning of its Sensex index options. These contracts attracted flows that shifted from other offerings. Simultaneously, the exchange actively onboarded new brokers and trading clients through competitive pricing, incentives, and enhanced liquidity, thereby expanding its active participant base. The recent Sebi norm requiring exchanges to offer only one index with weekly expiry contracts also aided BSE's market share, particularly with the discontinuation of Nifty Bank's weekly contracts.
Notional Turnover Trends
In notional terms, the overall F&O average daily turnover saw a decline of 16% to ₹389.56 lakh crore in 2025, following substantial growth in the preceding two years. While NSE's notional turnover fell by 35.3% this year, BSE's notional turnover surged by 51%. A BSE spokesperson noted that the exchange is a relatively new entrant in the active derivatives space, with Sensex derivatives relaunched less than three years ago, and the current growth is largely a catch-up phase responding to clear market demand.
Revenue and Future Outlook
BSE reported a 40% year-on-year increase in total revenue for the September quarter, reaching ₹1,139 crore. This growth was driven by transaction-related income, particularly from derivatives, listing income supported by strong fundraising, and co-location services. Sundararaman Ramamurthy, MD & CEO of BSE, highlighted increased institutional participation in options as a key driver of derivatives market share growth, with multiple steps taken to onboard more members and Foreign Portfolio Investors (FPIs).
Mangal expects the NSE to bounce back, but anticipates BSE will hold its ground. In the cash market, however, both NSE and BSE saw declines in average daily turnover.
Impact
This news suggests a significant shift in market dynamics within India's derivatives trading landscape. BSE's aggressive growth could lead to increased competition among exchanges, potentially offering investors more choices and influencing overall market liquidity and trading strategies. The success also points towards the potential for higher revenue streams for BSE from its derivatives segment. Market participants will closely watch how NSE responds and if BSE can sustain its momentum.
