Foreign exchange is a payment voucher expressed in foreign currency for international settlement. The International Monetary Fund's interpretation of foreign exchange is that foreign exchange is a creditor's right held by monetary management authorities (central bank, monetary institutions, foreign exchange stabilization fund and Ministry of Finance) in the form of bank deposits, treasury bonds and long-term and short-term government securities. Can be used when the balance of payments is in deficit.
