Central Bank of West African States

The Central Bank of West African States (BCEAO, Banque Centrale des États de l'Afrique de l'Ouest) is the supranational central bank of the West African Monetary Union (WAMU/UEMOA), issuing the West African CFA franc (XOF) for eight member states and conducting their common monetary policy under a fixed peg to the euro.¹

Mandate	Price stability is the prime purpose of monetary policy, defined as 2 percent CPI inflation with a margin of +/- 1 percentage point over a 24-month horizon¹^•³
Policy rates (2026)	Minimum bid rate 3.00%, marginal lending facility 5.00%, required reserve coefficient 3.0%⁴
Reserves	US$21.6 billion (4.6 months of imports) at end-2024, US$25.0 billion (5.0 months) in March 2025⁵
2019 reform	Operations account at the French Treasury closed, the 50% reserve deposit requirement ended, and ordinary French representation on BCEAO governing bodies ended; France remains financial guarantor²^•⁶

What the BCEAO is

The BCEAO is an international public institution of the WAMU member states with legal personality and financial autonomy, whose capital is subscribed in equal shares by those states.¹ Its core tasks are to define and implement monetary policy within WAMU, ensure the stability of the financial and banking system, foster the smooth running, supervision, and security of payment systems, implement the union's exchange rate policy, and manage the member states' official foreign reserves.¹

Colonial origins. The currency dates to December 1945, when, alongside the Bretton Woods negotiations, France created a single currency for its African colonies, the franc of the French Colonies of Africa, renamed the franc of the French Community of Africa in 1958. After independence (1958 to 1960), the colonial note-issuing banks were transformed into the present institutions, and the CFA franc was devalued by 50 percent on 11 January 1994, the same period that produced the treaties establishing WAEMU (10 January 1994) and CEMAC (16 March 1994).² The BCEAO's headquarters moved from Paris to Dakar, Senegal, in 1978 under the December 1973 monetary cooperation agreement.²

Legal foundations and governance

The bank operates under its statutes, which assign monetary policy to a Monetary Policy Committee (MPC) whose prime purpose is price stability while supporting WAEMU economic policies.¹ The bank's organs are the Governor, the Monetary Policy Committee, the Board of Directors, the Audit Committee, and National Credit Councils in each member state.¹

Appointments. The Governor is appointed by the Conference of Heads of State and Government of WAEMU for a renewable six-year term; deputy governors are appointed by the WAEMU Council of Ministers for renewable five-year terms.³ The 2010 statutes give the MPC one member nominated by the state responsible for guaranteeing the common currency's convertibility, with Council-appointed members serving five-year terms renewable once.¹ After the 2019 reform France no longer appoints a representative to the bank's governing bodies except when its guarantee might be invoked; the IMF describes the post-reform MPC as including the Governor as chair, the vice-governors, and 13 members appointed by the WAEMU Council of Ministers, among them an expert appointed in concertation with France.²^•³

How the currency peg works

The West African CFA franc is pegged to the euro at 1 euro = 655.957 CFA francs, and the French Treasury offers an unconditional and unlimited guarantee of convertibility, in the form of an advance to the central bank, in the event foreign exchange reserves are depleted.² The euro replaced the French franc as the anchor on 1 January 1999 with no change in parity.²

The operations account. In return for the guarantee, the BCEAO was historically required to deposit at least 50 percent of its foreign currency reserves in a special operations account at the French Treasury, a condition lifted in 2019.⁷ The guarantee was actually drawn, meaning the account ran a debit, only between 1980 and 1993.⁷ The original 1945 agreement had France guaranteeing only 20 percent of the franc zone money supply, whereas African countries now cover nearly all of their own money issuance.⁸ The statutes also build in a safeguard: Article 76 requires the MPC to reassess its policies when foreign exchange reserve coverage of the BCEAO's sight liabilities, essentially base money and government deposits, falls below 20 percent for three months.³

Monetary policy in practice

The BCEAO's inflation target is 2 percent with a +/- 1 percentage point band over a 24-month horizon, set under Article 8 of the statutes.³ Its main instruments are a policy corridor (minimum bid rate and marginal lending facility) and reserve requirements on banks.⁴

The inflation shock response. From mid-2022 the BCEAO raised policy rates by a cumulative 150 basis points between June 2022 and December 2023, first reducing the volume of refinancing supplied to banks by shifting from fixed to variable rates in early 2023, then re-injecting liquidity in the second half of 2023 through secondary-market purchases of sovereign securities and its emergency lending facility.³^•⁵ It purchased CFAF 2,000 billion of government securities in 2023 and then refrained from further purchases.⁵ Policy rates were left unchanged in 2024, with the effective refinancing rate at 5.5 percent, the ceiling of the corridor, and the interbank rate around 6 percent.⁵

Easing. From February 2025 the effective weekly financing rate fell to about 5 percent by end-March 2025.⁵ The Monetary Policy Committee then cut the minimum bid rate from 3.25 percent to 3.00 percent and the marginal lending facility rate from 5.25 percent to 5.00 percent, and set the required reserve coefficient at 3.0 percent to ensure the effectiveness of the policy rate.⁴

By the numbers

Reserves fell by US$8.4 billion over 2022 and 2023, rose by almost US$6 billion in 2024 to US$21.6 billion (4.6 months of imports), and rose a further US$3.4 billion in the first three months of 2025 to US$25.0 billion (5.0 months of imports); the estimated lower bound of reserve adequacy is 4.4 months of imports.⁵ By February 2026 reserves covered 7.8 months of imports, and WAMU recorded 6.6 percent real growth in 2025.⁹

Inflation. Average yearly inflation was 3.5 percent in 2024, ranging from 0.8 percent in Senegal to 9.1 percent in Niger, and stood at 2.1 percent year-on-year in February 2025.⁵

The other CFA zone and the eco

The CFA franc is issued by two separate institutions, the BCEAO and the Bank of Central African States (BEAC), producing two non-interchangeable monetary zones in which a banknote from one zone has no legal tender in the other.⁸ BEAC's headquarters moved to Yaoundé, Cameroon, in 1977, a year before the BCEAO's move to Dakar.²

The eco. ECOWAS leaders envisaged a single West African currency, the Eco, but its launch has been repeatedly postponed, most recently in 2020.⁷ The Convergence Council has stated that a 2027 launch remains achievable and asked the ECOWAS Commission to convene the Presidential Task Force to fast-track the process.¹⁰ A capital requirement of US$187 million for the future Central Bank of West Africa and a US$4.5 billion reserve-pooling mechanism have been approved, and in February 2026 the monetary union agreement and central bank statute were reportedly ready for adoption.⁹ The Eco is expected to operate under a flexible exchange-rate regime with inflation targeting, so WAMU members joining would trade euro-peg stability for greater shock absorption; intra-ECOWAS trade still accounts for less than 15 percent of total trade.⁹ Joining would also mean dismantling an 80-year-old monetary structure and replacing the French Treasury guarantee with new regional arrangements.¹¹

Recent developments

On 21 December 2019 in Abidjan, Presidents Macron and Ouattara announced four changes for the WAEMU side: renaming the West African CFA franc to ECO, closing the operations account at the French Treasury, ending the obligation to deposit 50 percent of foreign reserves with the Banque de France, and ending ordinary French representation on the BCEAO board, monetary policy committee, and Banking Commission audit functions, while France retained the convertibility guarantee at 655.957.⁶ France passed the reform in May 2020 (Loi 2020-1474) and WAEMU members ratified it through 2024; the CEMAC zone has not adopted the same package and continues with the historical operations account framework.⁶ The peg itself remained unchanged.⁹

Exit is hard. UEMOA's eight members deposit their foreign exchange reserves with the Dakar-based BCEAO, where reserves and liabilities are mutualized, which makes determining how much a departing country could walk away with difficult; this matters for the post-coup Sahel governments debating their relationship with the arrangement.¹²
