Foreign exchange swap
(FX swap).
A composite over the counter (OTC) transaction which involves:
(A) An exchange of two different currencies
- on a specific 'near leg' date
- at a fixed foreign exchange rate which is pre-agreed at the outset of the contract; and
(B) A reverse exchange of the same two currencies
- on a later pre-specified 'far leg' date
- at a fixed exchange rate which is usually different and which is also pre-agreed at the outset of the contract.
The uses of FX swaps include the transformation of short term borrowings or deposits from one currency into another.
The amounts of currency in the far leg re-exchange are generally greater than those in the near leg, by the amount of interest payable or receivable in the currency which the customer is swapping into.
For example, when hedging a deposit with a swap, the far leg amount will usually be greater than the amount in the near leg, by the amount of interest receivable on the swapped deposit.
Similarly, when hedging a borrowing using a swap, the far leg amount will normally be greater, by the interest payable on the swapped borrowing.
As the FX swap is an OTC contract, the provider and the customer are free to tailor the amounts of currency to be exchanged in this way, to meet the customer's individual hedging requirements.
The composite pricing of the FX swap is favourable for the price-taker, compared with the pricing of two related outright contracts, for example for spot exchange and forward re-exchange of the same currency pair.
FX swaps should not be confused with interest rate swaps, nor cross-currency interest rate swaps, which are different.
