What changed

The National Stock Exchange of India Limited identifies specific securities for inclusion under the Long Term Additional Surveillance Measure. These securities meet the criteria for surveillance. The exchange mandates a 100 percent margin rate for all open positions as of August 19, 2026, and for new positions created from August 20, 2026. Furthermore, the exchange shifts securities that qualify under criteria VII from the Rolling Settlement segment to the Trade-for-Trade segment effective August 20, 2026. This measure operates alongside other existing surveillance actions. The inclusion of a security under this framework results from market surveillance and does not represent an adverse action against the entity.
