A foreign exchange certificate (FEC) is a tool for foreign exchange control in countries where the national currency is subject to exchange controls or is not convertible.^[1] The arrangements vary significantly case by case.

Some of the main types of FEC are:

• A certificate for purchasing foreign currency at a specified rate, often for a specified purpose, such as financing imports. This type of certificates were required in many European countries after World War II.
• A certificate denominated in local currency, which foreign citizens are required to use for some or all of their purchases. The exchange rate may be more favourable for the visitor than the official commercial rate. The purpose is to channel the foreign exchange to the state coffers instead of the black market. This type of FECs was in use in Germany in 1931–1948 and China in 1980–1994.
• A certificate to which local citizens are required to exchange any foreign currency they receive as part of their salary or as remittances from relatives or friends who live abroad. These certificates may be accepted as payment in specific stores, which otherwise sell goods only to foreign citizens in exchange for foreign currency. This type of FECs was issued in the Soviet Union between 1961 and 1989.
• Certificates for circulation in closed economic zones (for example, the Svalbard ruble for employees of the Arktikugol coal mines). The purpose of such certificates was to prevent a shortage of goods in the event of an uncontrolled influx of money from outside the zone.
