A currency swap is a type of derivative consisting of two opposite conversion transactions. Both transactions in a currency swap are concluded for the same amount, but with different execution dates. In this case, the derivative is considered executed only after the second transaction is closed.
If the first transaction in the swap is the purchase of an asset, then the swap is called buy and sell, the reverse is called sell and buy.
This trading method is used to accumulate assets and obligations, increase security by reducing risks, and obtain credit funds secured by their assets.
