SEBI Revises Closing Auction Session Framework and Derivatives Settlement Methodology
The Securities and Exchange Board of India (SEBI) has revised the Closing Auction Session (CAS) framework for the equity cash market, effective December 7, 2026. The changes include a structured 10-minute auction window from 3:30 pm to 3:40 pm, revised order-entry rules, and a return to using the 30-minute volume-weighted average price (VWAP) from continuous trading to determine derivatives settlement prices on expiry days. These revisions follow market feedback and aim to improve price discovery, reduce volatility, and ensure orderly market closure.
