The National Stock Exchange has updated the list of securities subject to the Enhanced Surveillance Measure (ESM) framework. Securities identified in Annexure I are now subject to a minimum 100% margin requirement and will be shifted from the Rolling Settlement segment (Series: EQ/SM) to the Trade-for-Trade segment (Series: BE/ST) effective July 27, 2026. Additionally, securities transitioning to Stage II of the framework will be subject to a 2% price band under the Periodic Call Auction mechanism starting July 24, 2026. Securities listed in Annexure II are eligible to exit the framework. These measures operate alongside existing surveillance protocols and are based on market surveillance criteria rather than adverse actions against the entities.
