Did BSE actually overtake NSE in F&O turnover? This is why the maths could also be deceptive
At first look, BSE’s notional derivatives turnover jumped to about Rs 5,377 lakh crore in April, up almost 26% month-on-month, whereas NSE’s turnover dropped to round Rs 4,338 lakh crore, a 21.6% decline. This created the impression that BSE had briefly taken the lead in India’s largest buying and selling phase.
Nevertheless, analysts say this comparability is deceptive. The first situation lies in how by-product exercise is measured.
Notional turnover, which multiplies contract worth by underlying index ranges, can exaggerate volumes when index costs are larger. Analysts level out that such calculations can distort comparisons by as a lot as 19 share factors, making one alternate seem bigger even when precise buying and selling exercise is just not proportionally larger.
As a substitute, premium turnover — the precise cash paid for choices contracts — is taken into account a extra dependable measure and is extensively utilized by regulators like Sebi and institutional buyers. On this foundation, NSE continues to dominate.
In April, NSE retained 86.8% share in total F&O premium turnover and 62.9% share in index choices, even in what was described as a “holiday-distorted” month.
The distortion got here from the construction of expiry days, that are vital drivers of derivatives volumes.NSE’s flagship Nifty contracts expire on Tuesdays. In April, two key weekly expiry periods had been misplaced on account of holidays, instantly hitting volumes on the alternate. In distinction, competing contracts with Thursday expiries for BSE had been unaffected, quickly boosting exercise elsewhere.
Brokerage ICICI Securities highlighted an identical development in its be aware. NSE’s choices premium common each day turnover fell to Rs 64,500 crore in April, down greater than 31% from March, largely on account of fewer expiry days. In distinction, BSE’s premium turnover remained largely steady at Rs 33100 crore, displaying solely marginal progress.
The identical sample was seen in contract volumes. NSE’s common each day choices contracts dropped to 142 million in April, down almost 26% month-on-month, whereas BSE’s rose to 176 million, up about 20%.
Even then, mixed system-wide exercise really declined. Complete (NSE+BSE) choices premium turnover fell to Rs 97600 crore in April, down 23% from March, suggesting the general market cooled slightly than shifted meaningfully between exchanges.
The broader takeaway is that whereas BSE has been steadily gaining traction — particularly in choices contracts — the April crossover in notional turnover doesn’t mirror a structural change in market management.
