India’s securities regulator is reported to be preparing changes to part of its derivatives settlement framework after market participants raised concerns about volatility linked to a recently introduced closing-auction mechanism.
The Securities and Exchange Board of India introduced a closing auction session for determining closing prices in certain stocks connected to futures and options contracts. Feedback from the market has prompted the regulator to reconsider how the mechanism should apply to derivatives settlement.
Why the rule is being reviewed
Closing auctions are used in several global markets to concentrate liquidity and establish transparent end-of-day prices. In India, however, traders and institutions reported sharp movements around derivatives expiry, raising questions about whether the new system was producing unintended effects.
According to reporting on the review, SEBI received extensive feedback and may temporarily return to a volume-weighted average price methodology for derivatives settlement while retaining auctions in parts of the cash market.
Regulatory balancing act
Market-structure rules require regulators to balance price discovery, liquidity, transparency and protection against manipulation. A mechanism that works in one market may require adaptation to local trading patterns and the size of India’s derivatives segment.
A willingness to revise a new rule after receiving evidence from participants can be part of normal regulatory calibration. At the same time, frequent changes can create operational costs, making clear transition periods important for exchanges, brokers and investors.
What investors should watch
The final circular, implementation date and precise settlement methodology will determine the practical impact. Investors should rely on official SEBI and exchange notifications rather than act on reports of proposed changes.
The review also highlights the growing policy importance of India’s derivatives market. Regulators have increasingly focused on market stability and retail investor protection as trading volumes have expanded.
