The National Commodity & Derivatives Exchange Limited (NCDEX), on June 24, 2026, issued a circular regarding the applicability of the Event-based Additional Surveillance Margin (E-ASM) for select commodity derivatives, in continuation of its earlier surveillance circulars issued in 2019, 2020, and 2021.
Based on the prescribed High-Low price variation formula (High–Low)/Low×100, the Exchange has re-triggered an E-ASM of 2.5% for Coriander contracts following the commodity's 10-day price movement threshold. The additional surveillance margin will apply to all running Coriander contracts as well as contracts yet to be launched and will remain effective until July 16, 2026. The trigger date for the E-ASM was June 24, 2026.
The Exchange clarified that no E-ASM has been triggered for other monitored commodities, including Barley, Castor Seed, Guar Gum, Guar Seed, Jeera (including Jeera Mini), and Turmeric. All other applicable margins will continue to be levied in accordance with the prevailing risk management framework.
