The National Stock Exchange of India has updated the list of securities subject to the Enhanced Surveillance Measure (ESM) framework. Securities listed in Annexure I are now subject to a 100% margin requirement on all open and new positions, effective July 21, 2026. These securities will also shift from the Rolling Settlement segment to the Trade-for-Trade segment on the same date. Additionally, securities moving to Stage II of the framework will be subject to a 2% price band under the Periodic Call Auction mechanism starting July 20, 2026. Securities listed in Annexure II are removed from the framework, with their price bands reinstated to previous levels, provided no other surveillance measures apply. This action is a market surveillance measure and not an adverse action against the entities.
