NSE’s Biggest Revenue Engine Stutters As India’s Biggest Exchange Heads Towards IPO

Trading on the NSE’s derivatives segment took a hit in August 2026, as volumes and turnover shrunk across all product categories. The slowdown comes at an awkward time for the exchange, which is currently working on its initial public offering (IPO).

The exchange handled 2,501.69 million futures and options (F&O) contracts in August 2026, down 22.60 per cent from 3,232.06 million in July. Total turnover fell 22.39 per cent from Rs 42.66 lakh crore to Rs 33.11 lakh crore. The year-on-year (y-o-y) decline in volumes was much smaller though. NSE handled 2,514.98 million contracts in August 2025, making this year’s volume 0.53 per cent lower. But turnover fell 10.49 per cent from Rs 36.99 lakh crore a year ago.

The numbers suggest that while the number of contracts traded has remained broadly stable over the year, the value of those trades has fallen sharply.

Index options, NSE's single biggest source of transaction revenue, absorbed much of the damage. Contract volumes fell 23.15 per cent to 2,325.37 million from 3,025.82 million in July. 

Elsewhere, premium turnover fell 28.60 per cent to Rs 6.93 lakh crore from Rs 9.71 lakh crore. 

The y-o-y decline in volumes was much smaller though. Index options contracts fell 1.47 per cent from 2,360.04 million in August 2025. However, premium turnover was down 12.21 per cent from Rs 7.89 lakh crore last year.

Volumes have held up, but turnover has fallen, suggesting traders are taking smaller positions.

Stock options were the only segment to post year-on-year growth. Volumes fell 12.59 per cent month-on-month (m-o-m) to 142.87 million contracts, while premium turnover dropped 22.33 per cent to Rs 1.43 lakh crore. But compared to August 2025, volumes rose 20.58 per cent and premium turnover increased 30.06 per cent.

Index futures took the biggest hit in August. Volumes fell 30.84 per cent from July to 1.69 million contracts, while turnover dropped 30.23 per cent to Rs 2.76 lakh crore. Volumes fell 36.66 per cent and turnover dropped 44.71 per cent y-o-y.

Stock futures also fell. Volumes declined 21.29 per cent m-o-m to 31.76 million contracts, while turnover dropped 19.03 per cent to Rs 21.99 lakh crore. Volumes fell 6.04 per cent and turnover declined 4.40 per cent y-o-y.

The slowdown comes after a series of measures to rein in India’s derivatives market, including higher Securities Transaction Tax (STT), fewer weekly expiries, larger contract sizes, and tighter funding rules for proprietary trading desks. Traders are also adapting to NSE’s Closing Auction Session, introduced earlier this month.

The decline is a concern for NSE as options are a major source of its revenue. The exchange earned nearly Rs 10,000 crore in transaction charges from options in the year ended March 2026, accounting for about 60 per cent of its revenue from operations, according to its IPO filing.

The key question is whether the August decline is temporary or here to stay. Traders could adjust to the new rules and bring volumes back in the coming months. But if options activity stays weak, NSE could enter its IPO with a slower-growing business than it has had in recent years.
