On 21 December 2019, the French President Emmanuel Macron and the Ivoirian President Alassane Ouattara announced a “reform” of the monetary cooperation relations between France and the West African Economic and Monetary Union (UEMOA). This reform comes with a transformation of the CFA Franc and takes place in the context of a single currency project of the Economic Community of West African States (ECOWAS). The CFA Franc zone currently comprises of 14 sub-Saharan African countries belonging to two currency unions.  Benin, Burkina Faso, Côte d’Ivoire, Guinea-Bissau, Mali, Niger, Senegal and Togo are members of the West African Economic and Monetary Union (UEMOA), established in 1994 on the foundations of the West African Monetary Union, itself created in 1973. The other six countries - Cameroon, the Central African Republic, the Republic of the Congo, Gabon, Equatorial Guinea and Chad - are members of the Economic and Monetary Community of Central Africa (CEMAC). These two unions use the same currency, the CFA Franc, which stands for Communauté Financière Africaine (“African Financial Community”) in UEMOA and Coopération financière en Afrique centrale (“Financial Cooperation in Central Africa”) in CEMAC. Apart from Equatorial Guinea (Spanish) and Guinea Bissau (Portuguese), the other 12 countries have been French colonies (de facto or de jure). The CFA Franc is issued by the Central Bank of West African States (BCEAO) (for West Africa) and the Bank of Central African States (BEAC) (for Central Africa). Each of these currencies is legal tender only within its own region, thus not directly interchangeable.
