The CFA franc is a currency used in several African countries, primarily in West and Central Africa. It is divided into two variants: the West African CFA franc (XOF) and the Central African CFA franc (XAF). Both currencies are guaranteed by the French Treasury and are pegged to the euro, which helps stabilize their value. The CFA franc was introduced in 1945 and has undergone various reforms since then. It is used by 14 countries in the West African Economic and Monetary Union (UEMOA) and 6 countries in the Central African Economic and Monetary Community (CEMAC). The currency facilitates trade and economic cooperation among member states.
