What happened

Well supportedReported by 3 independent outlets

SEBI adjusted its rules for the Closing Auction Session (CAS) on October 15, 2026. While keeping the auction mechanism, the regulator removed its link to expiry-day settlement. Moving forward, expiring index contracts will settle based on the volume-weighted average prices (VWAP) of their constituents during the last 30 minutes of trading. The auction price will no longer determine the outcome of expiry contracts.
