SEBI Revises Closing Auction Session, Reverts to VWAP for Derivatives Settlement
The Securities and Exchange Board of India (SEBI) has revised its Closing Auction Session (CAS) framework, effective December 7, 2026, reverting to the volume-weighted average price (VWAP) method for settling derivatives on expiry days. The CAS will run from 3:30 pm to 3:40 pm with updated order-entry rules and trading timings. These changes follow market feedback highlighting volatility and liquidity concerns since CAS's August introduction. Analysts expect reduced expiry-day volatility and potential recovery in derivatives trading volumes, benefiting brokers more than exchanges.
