West African (Economic and) Monetary Union is a currency union whose exchange rate has been fixed to the French franc, with a major devaluation in 1994, and then, from 1999, to the euro. The scope for monetary policy is limited, but its operation has evolved slowly from direct towards indirect monetary instruments, and the union is becoming more integrated on financial and other dimensions.
