Three years after relaunching its Sensex derivatives platform with revised product specifications, BSE is seeing broader participation across retail and institutional investors, signalling growing acceptance of the product in India’s highly competitive equity derivatives market.

BSE had relaunched Sensex derivatives in May 2023 with a lower lot size and revised expiry structure aimed at improving accessibility and liquidity. Since then, the exchange has witnessed steady improvement in turnover, open interest and participant activity, according to exchange official.

“The growth in Sensex derivatives has been broad-based, with strong participation from all stakeholders including retail and institutional investors,” a BSE official said. Individual investors now contribute roughly 30 per cent of the total trading volumes in Sensex derivative contracts, reflecting rising retail engagement in the segment.

The exchange said institutional participation has also steadily improved over the past three years, helping deepen liquidity alongside improvements in technology infrastructure and product depth.

The relaunch came at a time when the derivatives market was witnessing rapid expansion, dominated largely by index options trading. BSE attempted to differentiate its product offering through changes in lot size and expiry-day structure.

“Product design plays a critical role and voice of customer is the most important in this regard,” the official said. BSE initially introduced Friday expiry contracts, later shifted to Tuesday under SEBI’s single-expiry framework and eventually moved expiry to Thursday to align with market preferences.

According to the exchange, Thursday expiries have historically seen stronger participation trends and fit well within its broader derivatives strategy while also allowing differentiated expiry cycles across exchanges.

The dataset viewed by businessline showed that the sharpest growth has been in options turnover. Sensex options notional average daily turnover (ADTV) surged from just ₹0.016 lakh crore in May 2023 to ₹268.3 lakh crore by April 2026. Premium turnover also expanded sharply from just ₹2.1 crore to more than ₹33,000 crore during the same period. Trading activity accelerated rapidly after the initial relaunch phase.

Market participants say the redesign improved accessibility for smaller traders by lowering capital requirements while helping market makers provide tighter spreads and better liquidity.

The exchange also downplayed concerns around the impact of tighter regulatory norms in the derivatives market, saying investor protection and market development should be viewed as complementary objectives.

“As a market infrastructure institution, BSE’s role extends beyond facilitating efficient trading to fostering responsible participation and informed investing,” the official said.

The exchange added that it continues to work closely with market regulator SEBI on investor awareness, risk disclosures and market education initiatives aimed at promoting sustainable participation in derivatives trading.

India’s derivatives market has remained under regulatory focus amid rising retail participation and concerns around speculative activity. However, exchanges believe that informed investors and stronger risk frameworks will support long-term market growth.
