SEBI points new guidelines for monitoring intraday spinoff positions

The Securities and Exchange Board of India (SEBI) late on Monday (September 1, 2025) issued contemporary guidelines for monitoring intraday positions in fairness derivatives.

The markets regulator has been reassessing the principles for fairness derivatives after it quickly banned U.S. high-frequency buying and selling agency Jane Street from the Indian markets, saying a few of its buying and selling methods have been manipulative and left retail buyers with losses.

The new framework, which is able to take impact from October 1, units an intraday internet place restrict of ₹5,000 crore per entity in index choices, in contrast with an end-of-day restrict of ₹1,500.

Gross intraday publicity has been capped at ₹10,000 crore, utilized individually to lengthy and brief positions, in keeping with SEBI’s assertion.

Stock exchanges will monitor compliance utilizing at the least 4 random snapshots in the course of the buying and selling day, together with one between 2.45 p.m. and three.30 p.m., when buying and selling exercise usually peaks, it added.

For entities breaching the boundaries, inventory exchanges will study buying and selling patterns and search a proof for such positions.

Breach of the boundaries on the day of contract spinoff expiry will appeal to a penalty, SEBI stated, including that the quantum of penalty will likely be determined by inventory exchanges.
