Another way of hedging exchange risks is by the use of currency
swaps. You are most likely to see currency swaps either between
banks, or between a member of a large group of companies and a
bank, usually hedging substantial borrowings or lendings.
The basic idea of a swap is explained at
CFM11090, and there is an example of an
interest rate swap at

an interest rate swap, in that the parties exchange interest
obligations for an agreed period. But it has extra complications
because two different currencies are involved. One of those
currencies may be sterling: equally, a UK company may enter into a
swap involving two different non-sterling currencies, for example
the US dollar and the Japanese yen.
All currency swaps have two basic components:
There may also be an initial exchange of currencies, but this is
optional.
You can best see how a currency swap works by looking at an
