Mumbai : The National Stock Exchange of India (NSE) has reaffirmed its leadership in the equity derivatives segment. NSE’s leadership performance is evaluated on premium turnover, the industry-standard metric that reflects actual economic activity.

The exchange demonstrated a clear upward trajectory in the first quarter of 2026. Its index options market share rose steadily from 66.7% in January to 72.1% in March—an increase of 540 basis points which underscores the strong underlying growth momentum. Even in April’s holiday-distorted month, NSE retained a dominant 62.9% share in index options and 86.8% in overall F&O premium turnover, underscoring its continued market leadership.

Two key weekly expiry sessions which are critical drivers of trading volumes, were lost due to holidays falling on Tuesdays, when NSE’s flagship Nifty contracts expire. In contrast, rival contracts expiring on Thursdays were unaffected, creating a temporary imbalance in reported activity. The broader trend signals recovery and strengthening market position.

Notional calculations artificially inflate competitor share due to higher index price levels, producing distortions of up to 19 percentage points. Premium turnover, by contrast, aligns with global best practices and is used by regulators such as SEBI and institutional investors.

NSE’s leadership stance stays clear and its market position remains robust, growth trajectory intact, and the volatility largely technical. The exchange continues to dominate India’s derivatives landscape, supported by deep liquidity, institutional trust, and structurally sound metrics.
