When discussing the CFA franc in West Africa, the Central Bank of West African States (BCEAO) is generally the institution that immediately springs to mind. This association is logical. It is the BCEAO that issues the currency, sets key interest rates, supervises the banking system, and steers the common monetary policy of the eight countries of the West African Monetary Union. However, reducing the management of the CFA franc to the BCEAO alone would be an oversimplification. Behind the common currency lies a broader institutional framework that also includes the West African Monetary Union (WAMU), the West African Economic and Monetary Union (WAEMU), and a set of monetary cooperation mechanisms inherited from the region's history.

To understand this organization, it is first necessary to distinguish between the day-to-day management of the currency and the political framework within which this management takes place. The BCEAO is the operational institution. It conducts monetary policy for the eight member countries: Benin, Burkina Faso, Côte d'Ivoire, Guinea-Bissau, Mali, Niger, Senegal, and Togo. When it raises or lowers its key interest rates, injects liquidity into the banking system, or strengthens certain prudential rules, its decisions have direct consequences on credit, savings, investment, and economic activity throughout the Union.

However, the BCEAO does not act entirely autonomously. Its mandate, objectives, and framework for intervention are defined by the texts governing the West African Monetary Union (WAMU). Created in 1962, WAMU is in fact the institutional foundation of the common currency. It organizes the sharing of a single currency among member states and establishes the main principles of regional monetary cooperation.

In practical terms, the BCEAO therefore operates within a framework collectively defined by the member states of the Union. The broad guidelines of monetary policy are not developed in an institutional vacuum. They are embedded in governance mechanisms involving, in particular, the WAEMU Council of Ministers and various decision-making bodies representing the member states.

The West African Economic and Monetary Union (UEMOA) adds a second layer to this architecture. Created in 1994, it does not directly manage the currency, but it seeks to harmonize economic, budgetary, fiscal, and regulatory policies within the regional area. This distinction is important because a common currency functions more effectively when the economies that use it adhere to a certain number of common rules.

The existence of budgetary convergence criteria illustrates this logic. In particular, the WAEMU sets a budget deficit target of 3% of GDP for member states. This rule is not directly related to monetary policy, but it influences the environment in which the BCEAO carries out its missions. A common central bank functions more easily when the public finances of the different states evolve within relatively coherent frameworks.

The issue of the CFA franc's exchange rate also involves broader mechanisms than just the Central Bank of West African States (BCEAO). Since the reform that came into effect in 2020, the CFA franc of the West African Economic and Monetary Union (WAEMU) remains pegged to the euro at a fixed rate of 655.957 CFA francs to one euro. This monetary stability relies on a cooperation agreement between the member states of the Union and France, which continues to guarantee the currency's convertibility.

This guarantee does not mean that Paris decides the monetary policy of the Union. Since the 2020 reform, French representatives no longer sit on the governing bodies of the BCEAO, except in certain specific situations related to the guarantee. Day-to-day monetary policy decisions are made by the West African institutions themselves. Nevertheless, the existence of a fixed exchange rate regime necessarily implies management constraints that extend beyond the central bank alone.

The functioning of monetary policy also depends on the Monetary Policy Committee of the BCEAO, which is now one of the institution's main decision-making bodies. It is within this body that guidelines relating to key interest rates, price stability, and the financing conditions of the economy are debated. Its decisions directly influence the cost of credit in a region that now has more than 150 million inhabitants.

Foreign exchange reserves also play a central role in this balance. At the end of 2024, according to BCEAO data, the Union's reserve levels were sufficient to cover several months of imports of goods and services. This ability to maintain adequate reserves helps to support the credibility of the exchange rate regime and preserve the monetary stability of the zone.

This institutional architecture explains why the management of the CFA franc cannot be reduced to a single institution. The BCEAO is the main player on a daily basis, but it operates within a framework established by the WAEMU, reinforced by the WAEMU's economic integration mechanisms, and governed by monetary agreements that influence the overall functioning of the zone.

This distinction is important for understanding the recurring debates surrounding the common currency. When it comes to changes in the exchange rate regime, reform of the CFA franc, or transformation of regional monetary governance, the decisions do not rest solely with the BCEAO. They also involve member states, the institutions of the Union, and the legal mechanisms that structure the entire monetary system.

Ultimately, the BCEAO constitutes the operational core of the system, but it is not its sole architect. The monetary stability observed in the WAEMU region results from a set of institutions, rules, and agreements that function in a complementary manner. Understanding this organization allows us to better grasp why monetary issues are often also political, institutional, and economic issues.
