A swap transaction is the simultaneous purchase/sale and sale/purchase of a currency for different value dates and at prices that reflect the interest differential between the concerned currencies for the stated period.
This product may be used to extend the maturity of an exchange commitment, or to use cash holdings in one currency to raise funds for a limited period in another.

Swaps are available in all currencies where forward exchange is available.

The maximum maturity date will depend on the concerned currency, although for most it is likely to be one year.
