This list is published when a Group 1, 2, or 3 currency’s spot risk margin rate is increased, because the volatility of the currency exceeds the volatility threshold that is set out in Dealer Member Rule 100.2(d)(v)(B)(a)1 [Subsection 5462(2) of the IIROC Rules]. In addition, the list is also published when the increased spot risk margin rate for the currency is reduced, because a minimum of 30 trading days has passed since the currency’s spot risk margin rate increase and the currency’s volatility no longer exceeds the volatility threshold.
Excess volatility in a currency is measured and tracked as an “offside day”. An offside day is triggered when the percentage change in the exchange rate of the currency over five-day intervals, through a period of 60 trading days, exceeds the margin rate for the currency group. When the number of offside base days during the period reaches 4, a margin surcharge is applied.
A Dealer Member must use the spot risk margin rates provided in the attached list, and Dealer Member Rule 100.2(d) [Sections 5461 to 5469 of the IIROC Rules] in margining unhedged foreign exchange customer and Dealer Member (inventory) positions and any other customer and Dealer Member transactions that result in an exposure to foreign exchange risk.
