Forex-swap is a financial term, which refers to "foreign exchange swap transaction", and sometimes it can be written as a swap alone. Swap transaction, also known as "foreign exchange transaction", refers to the foreign exchange transaction in which buyers and sellers exchange a currency with each other at a predetermined exchange rate for a period of time.
