What changed
BSE has updated the list of securities under the Enhanced Surveillance Measure (ESM) framework. Certain securities have been added to the framework, requiring a minimum 100% margin on open and new positions effective August 5, 2026, and a shift to the Trade-for-Trade settlement segment. Other securities are moving to lower stages or exiting the framework effective August 4, 2026. Securities shifting to Stage II are subject to a 2% price band and periodic call auctions starting August 4, 2026. These measures are part of ongoing market surveillance and do not constitute adverse actions against the entities. The framework operates alongside other existing surveillance measures, and price bands for exiting securities will be reinstated to their pre-shortlisting levels.
What you must do
- Maintain a minimum 100% margin on all open positions as of August 4, 2026, and on new positions created from August 5, 2026, for securities qualifying under the ESM.
