Explanation : A currency swap is the simultaneous purchase
and sale of a given amount of foreign
exchange for two different value dates. Swaps
are transacted between international
businesses and their banks, between banks,
and between governments when it is desirable
to move out of one currency into another for
a limited period without incurring foreign
exchange risk.
Currency swaps between multinationals are
frequently used both as a hedge and as a
means of securing overseas financing. The
swaps may be bilateral or multilateral. They
may be simple or highly complex. As a
relatively simple example, a French company
may have a Brazilian subsidiary that needs
more local currency for expansion. Through
an investment bank or a broker, the French
company locates a British firm whose
Brazilian subsidiary has surplus domestic
currency. The French company makes the
swap by buying the Brazilian cruzados from
the British company and simultaneously
entering into an agreement to reserve the sale
at some future date. Nominal interest rates
are agreed upon at the outset.
The swap is a hedge in the sense that foreign
currency liability is matched by a similar
foreign currency asset. Furthermore, neither
loan requires the approval of any government
agency, and the cost of funds can be cheaper
than funds from alternative sources. Besides,
the swap may be one of the few sources open
to non-resident companies for securing the
use of foreign exchange over a period of time
at a fixed rate.
