India’s securities regulator, SEBI, is re-evaluating its recently introduced closing auction system following feedback from market participants, marking a swift move to address potential issues after its debut in August.
India’s securities regulator has moved quickly to reassess its new closing auction system after market participants raised concerns that the mechanism may need adjustment, according to people familiar with the matter. Officials at the Securities and Exchange Board of India have held meetings this week with market makers, domestic mutual fund managers and stockbrokers to gather feedback on the framework, which only began operating on 3 August.
The review comes after SEBI spent nearly a year consulting on the idea of a closing auction session for the cash equity market. In December 2024, the regulator said the proposal was intended to improve the way closing prices are set, reduce tracking errors for passive funds and bring India closer to common global practice. It later extended the comment period into September 2025 to give stakeholders more time to respond.
The growing scrutiny suggests the new system is being tested in real market conditions sooner than regulators may have expected. Closing auctions are designed to concentrate trading at the end of the session and produce a single reference price, but such mechanisms can also draw close attention from high-frequency traders, fund managers and brokers if they affect execution quality or market impact. SEBI has not publicly detailed any proposed changes, and the discussions remain private.
