SEBI Revises Closing Auction Session Rules to Address Market Volatility
India's Securities and Exchange Board (SEBI) introduced the Closing Auction Session (CAS) in August 2026 to determine closing prices for stocks and derivatives, aiming to improve price discovery and reduce market manipulation. However, low participation and price volatility during CAS led to significant swings in options premiums and market instability. In response, SEBI decided to revert to continuous cash-market trading for settling expiring equity derivatives from December 7, while retaining a modified auction for official closing prices with a shorter transition period.
