BSE’s Claim of Overtaking NSE in F&O Turnover: Unraveling the Misleading Math Behind the Numbers.
Recent reports of the Bombay Stock Exchange (BSE) overtaking the National Stock Exchange (NSE) in the derivatives segment during April have caught the attention of market participants. Notably, BSE’s notional derivatives turnover surged to approximately Rs 5,377 lakh crore, marking a month-on-month increase of nearly 26%. Conversely, NSE experienced a downturn, with its turnover falling to around Rs 4,338 lakh crore, reflecting a decline of 21.6%. This significant disparity created a perception that BSE had triumphed in India’s primary trading segment for the first time; however, a deeper analysis of the data suggests that this shift might be more technical than indicative of a substantive change in market dynamics.
Analysts caution that relying on notional turnover to gauge market activity can be misleading, as it tends to exaggerate volumes based on higher index values. Such calculations could distort comparative measures by as much as 19 percentage points, giving a skewed view of market participation. A more accurate metric of activity is the premium turnover — the actual funds flowing into options contracts — which is preferred by regulatory bodies like Sebi and institutional investors. According to this measure, NSE continues to dominate the derivatives market, securing 86.8% of overall futures and options (F&O) premium turnover and 62.9% of index options in April, even amidst what was described as a “holiday-distorted” month affecting volume metrics.
Furthermore, the intricacies of expiry structures in the derivatives market have played a significant role in these figures. NSE’s key Nifty contracts expire on Tuesdays, and April saw the loss of two critical weekly expiry sessions due to holidays, directly impacting their volume. In contrast, BSE’s Thursday expiries remained unaffected, contributing to a temporary increase in BSE’s activity. Brokerage house ICICI Securities highlighted that NSE’s average daily options premium turnover plummeted by over 31% relative to March, whereas BSE maintained stable figures, showcasing minimal growth. Despite these fluctuations in individual exchange performance, total system-wide derivatives activity actually declined, indicating a generalized cooling in the market rather than a significant exchange leadership shift. Overall, while BSE’s gains in options contracts are noteworthy, they do not indicate a fundamental change in market hierarchy.
