On August 6, 2025, the Indian financial sector was abuzz with speculation over potential regulatory changes to weekly Futures and Options (F&O) expiries. The Securities and Exchange Board of India (SEBI) decisively addressed the rumors, asserting that reports suggesting an imminent curbing or complete ban of weekly index options expiry were speculative and not rooted in regulatory intent. Despite SEBI's clarification, the broader context reveals ongoing reforms and heightened scrutiny of the hyperactive derivatives market.
Key Developments:
SEBI stated that there is no plan, as of now, to abolish or restrict weekly F&O expiries, directly opposing widespread market rumors.
The regulator admitted it may revisit the expiry structure, but any future decisions would be data-driven and transparently communicated.
Ongoing regulatory review comes after major reforms in 2024 that already consolidated weekly expiries to just one index per exchange, with Nifty 50 retaining weekly contracts.
Recent enforcement against U.S.-based quant firm Jane Street for alleged expiry-day manipulation spotlighted surveillance gaps and sparked renewed debate on derivative speculation.
Following news reports, stocks of capital market intermediaries such as BSE, Angel One, and CDSL dropped by as much as 5.5%, reflecting investor anxiety over potential restrictions on derivatives turnover and volatility-dependent income streams.
Regulatory Stand: Clarity Amidst Speculation
SEBI officials, including Chairperson Tuhin Kanta Pandey, categorically denied that any immediate move to end weekly expiries is underway. While the market regulator has acknowledged industry concerns about excessive speculation by retail investors—reportedly, over 90% incur losses—SEBI stressed that any overhaul of derivatives product design will be thoughtfully executed after analysing fresh market data and consulting all stakeholders. The Jane Street episode, wherein the trading firm was barred and nearly Rs 4,840 crore was impounded, has been labelled primarily a surveillance issue, prompting SEBI to enhance early-warning mechanisms rather than resort to blanket bans.
Recent and Ongoing Reforms
Last November, SEBI restricted exchanges to a single weekly expiry on a benchmark index. Nifty 50 on the NSE and Sensex on the BSE now remain the only contracts with weekly options; other indices shifted to monthly expiries to reduce intraday volatility and speculative churn. In June 2025, prior to this week’s debate, trading schedules were further streamlined, mandating that contracts expire only on Tuesdays or Thursdays, and increasing lot sizes to heighten entry barriers for retail traders. These actions are part of a phased strategy to nudge the market toward more stable and less speculative trading practices.
Current Market Sentiment and Industry Reaction
Although the status quo is momentarily maintained, persistent media reports about possible regulatory tightening have led to acute short-term volatility in stocks linked to the capital market ecosystem. Investors’ response reflects the high dependence of many brokers and exchanges on derivatives turnover for revenue and the anticipated shift in trading strategies if further curbs are introduced. Brokerages warn of reduced liquidity and flexibility for traders going forward, and market analysts expect more consultation papers from SEBI in the coming months.
Looking Ahead: What Can the Market Expect?
While SEBI has not taken any immediate restrictive measures, the regulator remains cautious, signalling it may adjust expiry structures or introduce bi-monthly cycles if recent reforms do not sufficiently temper speculative flows and reduce loss rates among retail participants. Possible additional steps could include higher margins for options trading or increases in Securities Transaction Tax (STT) on derivatives to disincentivize rapid-fire speculation.
Conclusion
SEBI’s management of India’s unique F&O boom continues to walk a fine line between deepening market participation and enforcing robust safeguards. Today’s message: market reforms will be incremental, data-driven, and transparent—no sudden bans, but neither a freewheeling status quo. Investors and industry players should brace for continued evolution in derivatives market regulation, but with clarity that speculation about an immediate weekly expiry ban is unfounded as of now.
