SEBI Revises Closing Auction Rules, Restores VWAP for Derivatives Settlement from December 7
The Securities and Exchange Board of India (SEBI) has revised its closing auction session (CAS) framework, restoring the use of volume-weighted average price (VWAP) for settling expiring derivatives contracts from December 7. The original CAS, introduced in August 2026 to improve closing-price discovery, led to reduced trading volumes and increased volatility due to thin auction participation. SEBI's revision aims to address these issues by reverting to VWAP during the final 30 minutes of trading, with separate calculations for stock and index derivatives, reflecting a pragmatic regulatory adjustment.
