CFA Franc Reform and the ECO Currency: West and Central African Monetary Architecture Through 2026

The 2019 Macron-Ouattara accord rebranded the West African CFA but kept the EUR peg at 655.957. The ECOWAS ECO project missed its 2020 and 2027 anchor dates and now eyes 2027. The Sahel exits, the Faye-Sonko government in Senegal, the BEAC FX shortage, and the diverging Eurozone inflation differential are reshaping a monetary zone that covers 14 countries, roughly 200 million people, and around USD 250 billion in combined GDP.

The CFA franc, in circulation since 1945, anchors two distinct monetary unions. The West African CFA (XOF) is issued by the Banque Centrale des Etats de l'Afrique de l'Ouest (BCEAO) for the eight WAEMU members. The Central African CFA (XAF) is issued by the Banque des Etats de l'Afrique Centrale (BEAC) for the six CEMAC members. Both pegs were fixed at 1 EUR equal to 655.957 in January 1999 after the 1994 50 percent devaluation. In December 2019 Presidents Macron and Ouattara announced the WAEMU side reform: rename to the ECO, close the operations account at the French Treasury, end the requirement to deposit 50 percent of foreign reserves at the Banque de France, and remove French representatives from the BCEAO board and audit committee. France retains the convertibility guarantee. The reform was passed by France in May 2020 (Loi 2020-1474), ratified by WAEMU members through 2024, and implemented operationally on the BCEAO side. The CEMAC zone has not opted for the same reform package and continues with the historical operations account framework, although the 50 percent reserves rule was technically modernized in 2014 BEAC statutes. Separately, the wider ECOWAS bloc has pursued a 15 country single currency since 2000, also called the ECO, which has missed launch dates in 2003, 2005, 2009, 2015, and 2020. At the December 2024 Abuja summit ECOWAS reaffirmed a 2027 launch target. In January 2025 Mali, Burkina Faso, and Niger formally completed withdrawal from ECOWAS as the Alliance of Sahel States (AES), removing roughly 76 million people from the projected ECO area and proposing a Sahel currency. This brief evaluates the architecture, the macro indicators, the political economy, and the implications for sovereigns, banks, fintechs, and bilateral creditors through 2026.

Two zones, one peg, fourteen sovereigns #

Since the 1960s the West African branch reads as Communaute Financiere Africaine (XOF) and the Central African branch as Cooperation Financiere en Afrique Centrale (XAF). The two currencies are not interchangeable. Both are pegged to the euro at 1 EUR for 655.957 CFA, set when the euro replaced the French franc on January 1, 1999, and unchanged since the January 12, 1994 devaluation that halved the parity relative to the French franc.

WAEMU (UEMOA) was established by the Dakar Treaty of January 10, 1994 and gathers eight members: Benin, Burkina Faso, Cote d'Ivoire, Guinea-Bissau, Mali, Niger, Senegal, Togo. Combined population reached approximately 145 million in 2024 on World Bank WDI, combined GDP at current prices was roughly USD 200 billion on IMF WEO October 2024, and Cote d'Ivoire alone accounts for around 36 percent of bloc output. CEMAC was established in 1994 and gathers six members: Cameroon, Central African Republic, Chad, Republic of Congo, Equatorial Guinea, Gabon. Combined population was approximately 60 million, combined GDP near USD 95 billion, with Cameroon at around 45 percent of total and oil exporters dominating external dynamics.

Both blocs operate fixed exchange rate regimes with capital account convertibility into the euro, and inflation has tracked closer to the eurozone than to neighboring African economies. WAEMU headline inflation peaked at 7.4 percent in 2022, fell to 3.7 percent in 2023, and stood at 2.6 percent in 2024 on BCEAO bulletins. CEMAC inflation peaked at 5.6 percent in 2022 and was 4.0 percent in 2024 on BEAC reports. Both compare favorably with Ghana's cedi era inflation of 54 percent in December 2022 and Nigeria's naira inflation of 33 percent in mid 2024. WAEMU growth slowed to 5.3 percent in 2023 from 5.7 percent in 2022 because monetary policy could not loosen to offset the post-Russia commodity shock.

WAEMU (XOF)	Benin, Burkina Faso, Cote d'Ivoire, Guinea-Bissau, Mali, Niger, Senegal, Togo	145	200	2.6	BCEAO, headquartered in Dakar

The 2019 Macron-Ouattara reform: what changed and what did not #

On December 21, 2019 in Abidjan, French President Macron and Ivorian President Ouattara jointly announced four changes to the WAEMU side. First, the currency would be renamed from West African CFA to ECO. Second, the operations account at the French Treasury (Tresor), through which the BCEAO had pooled foreign reserves and accessed the convertibility guarantee, would be closed. Third, the obligation to deposit 50 percent of WAEMU foreign reserves at the Banque de France would end. Fourth, French representatives would be removed from the BCEAO board, the monetary policy committee, and the WAEMU Banking Commission audit functions. France retained the convertibility guarantee at the fixed parity of 655.957.

France converted the announcement into law through Loi 2020-1474 of December 3, 2020. The eight WAEMU governments completed ratification through 2024. BCEAO operationalized closure of the operations account by repatriating reserves to BIS deposits, ECB sovereign repo facilities, and a diversified custodian network, on BCEAO 2021 and 2023 annual reports. By April 2026 the rename to ECO had not formally taken effect because the broader ECOWAS ECO project created naming overlap, and successive ECOWAS Convergence Council communiques have asked WAEMU to delay the rename.

The reform did not address the underlying peg, the convertibility guarantee, or harmonization with CEMAC. Critics including Senegalese economist Ndongo Samba Sylla, French economist Kako Nubukpo (now WAEMU Commissioner), and Lionel Zinsou argue the operational changes leave intact the structural euro overvaluation problem. Defenders including Ouattara and successive BCEAO governors point to inflation anchoring and capital account convertibility as proven goods that more flexible regimes have not delivered.

ECO and the ECOWAS single currency, missed dates and the 2027 horizon #

The ECOWAS single currency project dates to the 1983 Lagos Treaty and the 2000 Accra Declaration. The bloc set up a West African Monetary Zone (WAMZ) in 2000 covering the non WAEMU members Ghana, Nigeria, Sierra Leone, Liberia, Gambia, Guinea, originally aiming for a sub-bloc currency by 2003 that would later merge with the WAEMU CFA. Launch dates were set, missed, and reset in 2003, 2005, 2009, 2015, and 2020. The convergence criteria require single digit inflation, fiscal deficits below 3 percent of GDP, public debt below 70 percent of GDP, and central bank financing of fiscal deficits below 10 percent of previous year tax revenue. Across 2023 Nigeria, Ghana, and Sierra Leone failed multiple criteria simultaneously, on the West African Monetary Agency 2023 macro convergence report.

At the 66th Ordinary Session in Abuja on December 15, 2024 the bloc reaffirmed a 2027 launch target and adopted a phased approach where countries meeting convergence criteria would adopt first. The communique placed Cote d'Ivoire, Senegal, and Togo from WAEMU plus Cabo Verde as initial compliant candidates. Nigeria, holding around 60 percent of projected ECO area GDP, would be a critical entrant but its naira regime, post the June 2023 Tinubu liberalization that took the official rate from around 460 to over 1,500 per USD by April 2024, complicates fixed parity entry on any near term horizon.

The naming dispute matters more than it appears. WAEMU members preserve the option to rebrand the existing CFA as ECO under a Phase 1 single currency model, effectively asking non WAEMU members to peg into the BCEAO regime. Anglophone members including Nigeria and Ghana have rejected this since 2020 as a backdoor extension of the euro peg. The 2024 communique left the architecture deliberately ambiguous.

Sahel exits, Senegal pivot, CEMAC FX shortage #

On January 28, 2024 the military governments of Burkina Faso, Mali, and Niger announced withdrawal from ECOWAS. Article 91 requires a one year notice, so formal exit took effect on January 29, 2025 after the AES Confederation Charter was signed in Niamey on July 6, 2024. The three remain WAEMU members and CFA users as of April 2026, although AES communiques from December 2024 and February 2025 announced intent to study a Sahel currency. Combined population of approximately 76 million is about 23 percent of the projected ECO area. WAEMU exit, if pursued, would require Treaty amendment or unilateral exit with reserve settlement and bond restructuring implications across BCEAO sovereign holdings.

Senegal's March 24, 2024 election brought Bassirou Diomaye Faye to the presidency with Ousmane Sonko as Prime Minister on a platform that included exit from CFA narrative as a campaign theme. In office, the Faye-Sonko government has prioritized fiscal audits over monetary regime change. The September 2024 audit by the Cour des Comptes documented previously unreported liabilities that pushed disclosed debt to GDP from 73.7 percent at end 2023 to roughly 99 percent on audit basis. The IMF EFF and ECF program approved in June 2023 was suspended pending reconciliation. As of April 2026 program negotiations remain open and CFA exit has not progressed beyond rhetorical positioning.

CEMAC faces a different stress. BEAC FX reserves stood at approximately EUR 7.5 billion at end 2024, around 4.5 months of import cover, on BEAC December 2024 minutes. The 2019 BEAC FX repatriation regulation requiring oil and mining exporters to repatriate at least 35 percent of export earnings within 150 days has been progressively tightened, reaching 70 percent under the 2024 regulation for new extraction concessions. Brent oil at USD 65 to 75 across 2025 and Q1 2026 has compressed Equatorial Guinea, Gabon, and Congo fiscal positions. Cameroon, the non oil anchor, ran a current account deficit of around 4.0 percent of GDP in 2024 on IMF Article IV. The fixed peg has not adjusted.

Country	Bloc	GDP 2024 USD billions	Public debt percent of GDP 2024	Current account percent of GDP 2024	IMF program status April 2026
Cote d'Ivoire	WAEMU	86	57	minus 4.6	EFF and ECF, on track

Implications for sovereigns, banks, fintechs, and bilateral creditors #

WAEMU sovereign issuance benefits from peg credibility. Cote d'Ivoire's January 2024 USD 2.6 billion dual tranche Eurobond cleared at 7.625 and 8.25 percent for 9 and 13 year tenors, the first Sub Saharan Africa Eurobond since the rate cycle. Senegal spreads widened after the September 2024 audit, with the 2033 USD bond moving from approximately 470 basis points over US Treasuries pre disclosure to over 750 basis points by end 2024. The bid for WAEMU paper rests partly on the implicit French convertibility backstop.

French exposure runs through several channels. The convertibility guarantee creates contingent liability on the French Treasury, although it has not been drawn upon since the 1994 devaluation period. French defense expenditure under Operation Barkhane, peaking at approximately EUR 900 million annually, has been redirected following the 2022 to 2024 expulsions from Mali, Burkina Faso, and Niger. AFD commits EUR 4 to 5 billion annually to Africa, of which a meaningful fraction flows to CFA zone sovereigns. The Wagner-then-Africa Corps Russian presence in Mali, Burkina Faso, CAR, and Niger, alongside intensified Chinese lending, reshapes the political backdrop without yet displacing the euro peg architecture.

Banking and fintech regulation converges only partially. WAEMU mobile money transactions reached approximately USD 480 billion in 2023 on GSMA Mobile Money State of the Industry 2024, with Orange Money, Wave, and MTN MoMo dominant. Wave, a Senegal headquartered fintech valued near USD 1.7 billion on its 2021 Series A and serving over 20 million customers, pushed BCEAO to issue the 2022 e-money regulation. The CEMAC equivalent remains less developed. A unified ECO area would have to harmonize e-money licensing, AML frameworks, and FX surrender rules across regimes ranging from highly liberalized (Cote d'Ivoire, Senegal) to tightly controlled (Equatorial Guinea, Chad).

Recommendations through end 2026 #

For francophone sovereigns, three actions matter. First, WAEMU members compliant with ECOWAS convergence criteria (Cote d'Ivoire, Senegal on program reset, Togo) should publicly accept Phase 1 ECO entry on fixed parity, preserving the euro peg through a transitional regime to 2030. Second, AES members should formalize WAEMU continuation publicly to avoid spreading uncertainty across BCEAO sovereign holdings, even if AES political coordination continues outside ECOWAS. Third, CEMAC governments should commission an open Article IV consistent peg review by end 2026 rather than wait for an oil shock to force the discussion.

For French policy makers, the convertibility guarantee should be maintained without expansion. The Treasury and AFD should publish annual contingent liability disclosure on guarantee exposure. Defense and development budget consolidation following the Sahel withdrawals should be presented as stable commitment to avoid reinforcing exit narratives.

For private creditors and multilateral lenders, WAEMU sovereign Eurobonds remain a relative value trade at 200 to 350 basis points over French OATs, with Cote d'Ivoire as the natural anchor. CEMAC issuers should be priced 150 to 250 basis points wider than WAEMU equivalents. Pan African banking franchises should hedge ECO transition risk through 2027 with the working assumption that any rebrand preserves rather than breaks the peg. The single biggest tail risk, a CEMAC peg break following sustained oil weakness, deserves explicit option pricing over the 18 to 24 month horizon.
