The CFA franc combines two questions that do not always sit comfortably together: how countries can share a stable currency, and how much monetary independence they should surrender to do so. Its history runs from French colonial administration to African regional central banks, a major devaluation and an enduring link to Europe’s currency.
Within the broader development of foreign exchange trading in Africa, the CFA system represents a different approach from national floating currencies. Member countries pool monetary responsibilities rather than maintain separate exchange rates. The benefits and costs become clearer once the two CFA currencies are distinguished.
Two CFA Francs, Not One Currency
“CFA franc” refers to two separate currencies serving 14 countries. The West African CFA franc carries the currency code XOF; the Central African CFA franc carries XAF. They have separate issuers and monetary institutions, despite sharing a name and the same official euro conversion rate.
| Feature | West African CFA franc | Central African CFA franc |
|---|---|---|
| Currency code | XOF | XAF |
| Central bank | Central Bank of West African States, or BCEAO | Bank of Central African States, or BEAC |
| Economic and monetary grouping | West African Economic and Monetary Union, or WAEMU/UEMOA | Central African Economic and Monetary Community, or CEMAC |
| Member countries | Benin, Burkina Faso, Côte d’Ivoire, Guinea-Bissau, Mali, Niger, Senegal and Togo | Cameroon, Central African Republic, Chad, Republic of the Congo, Equatorial Guinea and Gabon |
| Official euro parity | €1 = CFA 655.957 | €1 = CFA 655.957 |
The matching rate should not be mistaken for a single banking area. When assessing a payment, currency balance or proposed reform, identifying whether it concerns XOF or XAF is the first step. An announcement about the BCEAO does not automatically change arrangements at the BEAC.
From Colonial Currency to Monetary Union
The CFA franc was created on December 26, 1945. Its original name, franc des Colonies Françaises d’Afrique, explicitly identified it as a currency of France’s African colonies. Later names replaced that colonial wording with references to African financial community and cooperation. The BCEAO’s historical record also documents the subsequent changes in parity and the restrictions introduced in 1993 on redeeming banknotes across the two currency areas.
That origin matters because the currency did not begin as an agreement negotiated among independent African states. Its later survival, however, involved new treaties, regional institutions and decisions by sovereign governments. Treating the present system as unchanged since 1945 misses those developments; treating its colonial origins as irrelevant misses why monetary reform carries political weight.
The wider history of colonial currency systems and their legacy provides the background. The narrower CFA question is how an inherited monetary arrangement became a framework for cooperation between independent countries.
Membership and Institutions Changed After Independence
The West African Monetary Union, or UMOA, was established by a treaty signed on May 12, 1962, with a replacement treaty signed in November 1973. Membership was not fixed permanently: Mali introduced its own currency in 1962 and rejoined the union in 1984; Mauritania withdrew in 1973; Guinea-Bissau joined in 1997. These changes appear in the BCEAO’s institutional chronology.
These departures and accessions are worth separating from changes to the currency’s value. Leaving a monetary union changes the institutions responsible for money. Devaluing a shared currency changes its external price. Neither necessarily requires the other.
In Central Africa, the BEAC was created on November 22, 1972. Its responsibilities extend beyond issuing banknotes to monetary policy, foreign exchange reserves, payments and financial stability. The BEAC’s institutional history records later developments including the creation of the regional banking commission in 1990 and the launch of a money market in 1994.
The practical result was a broader form of cooperation than a shared banknote design. Regional institutions acquired responsibilities that would otherwise belong to national central banks and supervisors.
The 1994 Devaluation: Stability Had a Breaking Point
On January 12, 1994, the CFA franc’s value against the French franc was cut by half. The rate moved from 50 CFA francs per French franc to 100. The devaluation followed years of economic strain and was intended to restore competitiveness. Recovery involved more than the exchange rate alone, including adjustment programmes and changing commodity prices, as documented in the IMF’s assessment of the devaluation’s aftermath.
The arithmetic can cause confusion. The CFA price of one French franc doubled, but the French franc value of one CFA franc halved. Those are two descriptions of the same movement, not competing estimates.
Consider a simplified importer with a bill for 10,000 French francs. Before the change, the currency conversion required 500,000 CFA francs. Afterwards, it required 1 million, before fees or any renegotiation. An exporter receiving the same foreign currency amount would obtain twice as many CFA francs, although imported materials could also become more expensive.
This example illustrates the distributional problem. Devaluation can help some producers while squeezing importers and households whose spending depends on foreign goods. It does not create an equal gain or loss for everyone.
The episode also provides a warning about vocabulary: a fixed exchange rate is not an unchangeable exchange rate. A peg removes routine market fluctuations against its anchor while leaving open the possibility of an official adjustment.
From the French Franc to the Euro
On January 1, 1999, the euro replaced the French franc as the CFA currencies’ anchor. The resulting parity was €1 to CFA 655.957. This was a conversion of the existing relationship, not another devaluation. Both currencies retain a French Treasury convertibility guarantee under the official monetary cooperation framework.
For a hypothetical €10,000 invoice, the parity gives a conversion amount of CFA 6,559,570. That calculation describes the exchange rate component, not a promise that every payment service will charge exactly that amount. A business should distinguish the currency conversion from any transfer charges.
The euro link also does not freeze the CFA franc against every other currency. The relationship with the US dollar changes as the euro moves against the dollar.
Take two illustrative exchange rates, not current quotations. If €1 buys $1.20, a $12,000 invoice equals €10,000, or CFA 6,559,570. If €1 buys only $1, the same invoice equals €12,000, or CFA 7,871,484. The dollar bill has become more expensive in CFA francs even though the euro peg has not moved.
For a company earning CFA francs and buying goods priced in dollars, that distinction matters more than the label “stable currency”. Stable against which currency is the useful question.
What Regional Monetary Cooperation Can Achieve
A shared currency removes the need to exchange national currencies for transactions within its monetary area. It also makes prices easier to compare. Those advantages come with a cost: members surrender the exchange rate between them as an adjustment tool. The French Senate’s examination of monetary integration addresses both sides, including the difficulty of responding to shocks that affect member countries differently.
Consider a hypothetical Senegalese wholesaler purchasing goods from Côte d’Ivoire in XOF. There is no separate Senegalese currency to convert into an Ivorian currency. That removes one source of uncertainty from the contract. It does not remove freight charges, late deliveries, credit risk or disagreement over the quality of the goods.
The same distinction applies to investment. A common currency can simplify comparisons between projects, but it cannot make two borrowers equally creditworthy. Currency unity should not be confused with uniform commercial conditions.
Sharing Monetary Policy Means Sharing Constraints
Suppose one member economy suffers a poor harvest while another experiences an investment boom. The first might benefit from easier financing; the second might need restraint to prevent excessive borrowing. A regional central bank must weigh both conditions rather than set a separate policy for each country.
This is the central bargain of monetary union. Governments gain a shared monetary framework but lose an instrument they could otherwise adjust nationally. Fiscal policy, productivity, wages and the movement of workers and capital must carry more of the adjustment.
Neither side of that bargain should be exaggerated. A national currency would offer more discretion, not guaranteed prosperity. A common currency offers consistency, not immunity from recession.
The Sovereignty Question Is More Than a Currency Name
Monetary sovereignty has several parts: who appoints decision makers, who sets policy, who manages reserves and who decides the exchange rate regime. Changing one part does not automatically change the others.
For that reason, a useful assessment of CFA reform should separate three questions. Should neighbouring countries share a currency? Should that currency remain fixed to the euro? Should France continue providing a financial guarantee? A country can favour regional cooperation while wanting a different answer to either of the other questions.
This distinction also helps avoid an unhelpful choice between defending every existing arrangement and rejecting all monetary cooperation. Regional ownership and regional coordination are compatible goals. The harder task is agreeing on how policy decisions and the costs of a crisis would be shared.
What the West African Reforms Changed
The cooperation agreement signed on December 21, 2019 changed the West African arrangement. The BCEAO’s operations account at the French Treasury was closed, and France ceased appointing its ordinary representatives to the central bank’s governing bodies. Safeguards associated with potentially calling on the guarantee remained. The Banque de France’s account of the revised institutions distinguishes this framework from Central Africa, where French representation continues.
The removal of the BCEAO’s obligation to place part of its reserves at the French Treasury did not mean abandoning regional reserve management. Nor did it mean ending the euro peg or the convertibility guarantee.
These distinctions correct two opposite mistakes. It is inaccurate to describe the West African arrangements as wholly unchanged. It is also inaccurate to treat the reforms as the abolition of every monetary connection with France.
Institutional reform should therefore be judged by the powers transferred and obligations removed, not solely by the announcement of a new currency name.
The Eco and the Next Test of Cooperation
The proposed Eco currency belongs to the wider debate about West African monetary integration. A proposed name, a political agreement and an operating currency union are different stages. The IMF’s 2026 assessment of WAEMU common policies continued to treat a broader ECOWAS currency union as a prospective project requiring economic convergence and attention to risks, rather than a completed replacement.
Any successor arrangement would need more than new notes. Governments would have to agree on central bank governance, reserve management, fiscal discipline, banking supervision and support during crises. They would also need a workable transition for deposits, debts and commercial contracts.
The CFA experience makes the central lesson plain: a common currency can survive for decades, but its durability does not settle every argument about its design. Cooperation must remain credible to the governments, businesses and households using the money.
For comparison, the history of monetary independence and the creation of national currencies examines the alternative route. The choice is not simply between independence and dependence. It is between different ways of allocating monetary authority, managing external risk and bearing the cost when economic conditions change.
