• Based on the High–Low price variation formula (High–Low)/Low×100(High–Low) / Low × 100 (High-Low)/Low×100, the E-ASM of 2.5% has been re-triggered and made applicable to all running and yet-to-be-launched contracts in Guar Seed, Guar Gum, and Turmeric.
• This enhanced surveillance measure will remain in force up to January 19, 2026, to manage price volatility in these commodities. The trigger was activated due to significant price movements observed over the specified monitoring periods.
• As per the applicability details, Guar Gum triggered E-ASM under both 5-day (10%) and 10-day (15%) movements on December 29, 2025, Guar Seed under the 10-day movement, and Turmeric under the 5-day movement.
