MANAGING FOREIGN EXCHANGE RATE RISK
Banks are exposed to a number of potential foreign exchange risks. Foreign exchange risks may arise as a result of cash exposures or from exposures to instruments denominated in a foreign currency. Risks arise when there is a mismatch between the value of assets it owns denominated in a foreign currency and the value of what it owes in the same currency. A mismatch may also occur as a result of payments it expects to receive, or is committed to make, in a foreign currency at a future time. The former exposures are referred to as spot positions and the latter forward positions:
Long.A bank may have a long spot foreign currency position if it has foreign currency in the form of cash or owns an asset denominated in a foreign currency. It may have a long forward position if it expects to receive a future payment in a foreign currency or expects to receive an asset at a future date that is denominated in a foreign currency. Short. A bank may have a short spot foreign currency position if it owes foreign currency in the form of cash (for example, in the form of a deposit taken by a bank in a foreign currency) or a financial instrument denominated in a foreign currency. It may have a short forward position if it is committed to making a future payment in a foreign currency or to deliver an asset at a future date that is denominated in a foreign currency.
The overall spot and forward position is calculated for each foreign currency by adding up the individual spot and forward positions in that currency. It has a flat position if its assets in one currency are equal to its liabilities in both the spot and forward markets.
A US bank that has a long spot position in euros worth $100m at current exchange rates but also owes yen to the value of $100m does not have a flat position. It has a long euro position and a short yen position. If the bank also owes the equivalent of $100m in euros at current exchange rates for delivery in one month’s time the bank does have a flat euro position overall even though it is long in the spot market and short in the forward.
