This National Commodity & Derivatives Exchange (NCDEX) on August 06, 2026 issued circular about Event-Based Additional Surveillance Margin (EASM) — an extra margin requirement that kicks in automatically when a commodity's price shows unusually high volatility, to curb excessive speculation.
This mechanism was originally introduced via earlier circulars (2019, 2020, 2021) and applies to select agricultural commodities.
The trigger is based on price volatility: [(High−Low)/Low × 100], measured over 5-day and 10-day windows.
For Turmeric, the 10-day price movement crossed the 15% threshold on August 6, 2026, which re-triggered the EASM.
As a result, an additional margin of 2.5% will now apply to all existing and upcoming Turmeric contracts until August 27, 2026.
Other commodities listed (Barley, Castor Seed, Coriander, Guar Gum, Guar Seed, Jeera) are currently not triggered ("NA") — meaning no additional margin applies to them right now.
Turmeric futures on NCDEX have become volatile enough to trigger a temporary extra margin (2.5%) on all trades, effective until August 27, 2026, as a risk-control measure. No other commodity is currently affected.
