What changed

The National Stock Exchange of India updates the list of securities under the Enhanced Surveillance Measure framework. Securities in Annexure I attract a 100 percent margin requirement. These securities move from the Rolling Settlement segment to the Trade-for-Trade segment on August 18, 2026. Securities in Annexure II exit the framework. Securities that move to Stage II undergo Trade-for-Trade settlement with a 2 percent price band under Periodic Call Auction starting August 17, 2026. The exchange applies these measures for market surveillance purposes. Market participants must note that these measures exist alongside other prevailing surveillance rules. The exchange reinstates the original price band for securities that exit the framework unless other surveillance measures apply.

Sub: Applicability of Enhanced Surveillance Measure (ESM)

This is with reference to Exchange Circular nos. NSE/SURV/56948, NSE/SURV/57609, NSE/SURV/63361, NSE/SURV/64066, NSE/SURV/64400, and NSE/SURV/69315 dated June 02, 2023, July 18, 2023, August 09, 2024, September 20, 2024, October 04, 2024, and July 25, 2025 respectively in respect of Enhanced Surveillance Measure (ESM).

Members are hereby requested to note the following:

  • The securities as per the attached Annexure I have satisfied the criteria for inclusion under aforesaid measure and shall attract a minimum 100% margin w.e.f. August 18, 2026, on all open positions as on August 17, 2026, and new positions created from August 18, 2026.
  • The securities as given in Annexure II, are eligible to move out from the said framework.
  • A consolidated list of securities under the framework is given in Annexure III.

Securities qualifying under ESM shall be shifted from Rolling Settlement segment (Series: EQ/SM) to Trade-for-Trade segment (Series: BE/ST) w.e.f. August 18, 2026.

Additionally, securities shifting to Stage II shall be under Trade for Trade with price band of 2% under Periodic Call Auction w.e.f. August 17, 2026.

Market participants may note that the ESM framework shall be in conjunction with all other prevailing surveillance measures being imposed by the Exchanges from time to time.

The Price Band of a scrip moving out of the framework shall be reinstated to the Price Band applicable to that scrip before it got shortlisted under the respective framework. This will be subject to the scrip not being shortlisted or part of any other Surveillance measure, in which case, the price band of the relevant surveillance framework will prevail.

Further, it may also be noted that the shortlisting of securities under ESM is purely on account of market surveillance, and it should not be construed as an adverse action against the concerned company / entity.
