The National Stock Exchange of India updates the list of securities under the Enhanced Surveillance Measure (ESM) framework. Securities listed in Annexure I move into the framework and attract a 100 percent margin requirement. These securities shift from the Rolling Settlement segment to the Trade-for-Trade segment effective September 1, 2026. Securities listed in Annexure II exit the framework. Securities that move to Stage II of the framework enter the Trade-for-Trade segment with a 2 percent price band under Periodic Call Auction effective August 31, 2026. The ESM framework operates alongside other existing surveillance measures. This action results from market surveillance and does not represent an adverse action against the affected entities.

- Apply a minimum 100 percent margin on all open positions as of August 31, 2026, and new positions created from September 1, 2026, for securities in Annexure I.
