BSE identifies specific securities for inclusion under Short-Term Additional Surveillance Measure (ST-ASM) Stage I and Stage II. For Stage I securities, the margin rate is 50 percent or the existing margin, whichever is higher, capped at 100 percent. For Stage II securities, the margin rate is 100 percent. These measures apply to all open positions as of June 17, 2026, and all new positions created from June 18, 2026. The ASM framework operates alongside other existing surveillance measures. Inclusion in the framework results from market surveillance and does not constitute adverse action against the entity. Price bands for securities that exit the framework return to their previous levels, unless other surveillance measures apply.
What you must do
- Apply a 50 percent margin rate or existing margin, whichever is higher, for Stage I securities.
- Apply a 100 percent margin rate for Stage II securities.
