There is a separate haircut calculated for each foreign (i. e., non-USD) currency. The first thing we need to do to calculate the haircut on a given currency is to figure out the firm's total exposure to that currency. A negative currency position indicates that the firm is short (or owes) the currency. There are two ways the accompanying spreadsheet will show currency exposure: 1) Actual cash is denoted 'cash' in the Position Symbol column, and can be in a variety of different currencies. You can see the symbol for the currency of the cash in the Currency column (EUR = Euro, GBP = British Pound, BRL = Brazilian Real, USD = US Dollar). The USD value of the cash is shown in the Market Value (USD) column. There may be several cash lines for the same currency due to the positions being in different accounts.
2) We also have forwards. A forward is an agreement to buy a currency in the future. For risk purposes, it is essentially the same as actually owning the currency. So if we show a 'Forward EUR' position with a market value in USD, this is the same (for risk and haircut purposes) as if we had 'cash' with 'EUR' in the Currency column.
Add up the pieces to get to the total exposure for a currency, and apply a haircut to the absolute value of that total exposure. If the firm is long and short the same currency (whether in cash or forwards), the total currency risk is the net position in that currency.
The haircut for GBP and EUR is 6%, while the haircut for ZAR and BRL is 20%. There is no haircut for USD positions.
