Can Ecowas Finally Achieve Its Decades-Old Single Currency Dream?

After four decades of delays, West Africa plans to launch a shared currency, the Eco, in 2027. The prize is easier trade; the test is whether economies and politics can finally converge.

Picture a fabric trader in Lomé, Togo, loading bales of cloth onto a bus bound for Lagos, Nigeria, a journey of maybe 400 kilometers. 

Before she even sells a single yard, she has to change her CFA francs into naira. If she sources dye from Accra on the way back, that’s a third currency, the Ghanaian cedi.

Every conversion carries a fee; every exchange-rate swing at every border crossing can erase part of her margin. The same product is priced three ways, while the trader absorbs the uncertainty.

Multiply her small hustle by the millions of traders, transporters, and small business owners who move goods across West Africa’s 15 countries every day.

Then you start to see why Ecowas—the Economic Community of West African States—has spent over four decades chasing a single regional currency.

The idea has kept getting pushed back. 

But this month, the bloc’s leaders meeting in Lungi, Sierra Leone, once again reaffirmed their commitment to launching the Eco in 2027.

And this time there are a few genuinely new details worth understanding, alongside all the old reasons to stay cautious.

A dream decades in making

The Eco’s roots go back to May 1983, when Ecowas heads of state meeting in Conakry, Guinea first ordered studies for a unified West African monetary zone. 

The goal then, as now, was to stitch together a region split by colonial-era currency lines: the French-speaking countries using the euro-pegged CFA franc (managed by shared central bank BCEAO), and English- and Portuguese-speaking countries each running their own national currencies (the naira, the cedi, the leone, and so on).

In 1987, leaders adopted a program aimed at creating a single monetary zone. 

The ambition was written into the 1993 Revised Ecowas Treaty, which called for a regional central bank and a single currency.

A common currency needs common rules first, so in 2000, six countries—Nigeria, Ghana, Guinea, Sierra Leone, Liberia, and The Gambia—signed the Accra Declaration, creating the West African Monetary Zone (WAMZ). 

The plan was for WAMZ to launch its own currency first, then merge it with the CFA franc used by the eight-country West African Economic and Monetary Union (Waemu/Uemoa) bloc. 

That WAMZ currency kept slipping, from 2003 to 2005, then 2010, then 2015, mostly because member countries couldn’t meet the economic targets set for joining.

In 2019, Ecowas finally settled on a name for the whole-region project, targeting a 2020 launch. 

Then things got messy: Ivorian President Alassane Ouattara announced separately that the existing CFA franc would simply be renamed “eco” and reformed, cutting some of France’s remaining oversight while keeping the currency pegged to the euro. 

Nigeria and other WAMZ countries pushed back hard, saying that wasn’t the Ecowas-wide eco they’d agreed to at all—it was a rebrand of the CFA franc under a different name. 

That disagreement, layered on top of Covid-19 and years of missed economic targets, pushed the launch date to 2027, a target reaffirmed in 2021, 2023, and again this year.

Why the dream keeps slipping

To share a currency, countries need reasonably similar economies, a concept called an “optimum currency area.” 

If one country’s economy is booming while another’s is in recession but they can’t each adjust their own exchange rate or interest rate to cope, the currency union creates strain rather than relief (this is roughly the story of some struggles inside Europe’s eurozone).

To share money safely, economies need convergence, meaning key indicators must stay within agreed limits.

Ecowas tried to build in safeguards through convergence criteria, essentially a shared report card all member countries are supposed to pass before adopting the Eco. 

The four main tests are: keeping inflation in single digits, a budget deficit no larger than 4% of GDP, limiting how much a government borrows from its own central bank, and holding enough foreign currency reserves to cover at least three months of imports. 

The rules matter because one country’s indiscipline can become everybody’s problem. 

If a member borrows excessively or allows inflation to surge, investors may question the common currency, raising financing costs across the union.

As of the most recent comprehensive assessment on record, only Ghana had ever managed to hit all four in a single year—and only once. 

The hardest issue is whether West African economies behave similarly enough for one monetary policy. A shared central bank sets one main interest rate.

That rate may suit an economy fighting inflation but hurt another that needs cheaper credit to recover from recession.

A fall in oil prices can damage an oil exporter while helping an importer. 

A drought may strike agricultural economies harder than service-based ones.

Economists call this an asymmetric shock: an event that hits members differently.

Waemu’s CFA franc countries tend to move together economically (unsurprising, since they already share a currency and central bank).

Meanwhile, non-Waemu countries like Nigeria and Ghana respond quite differently to the same economic shocks. This means a shared monetary policy could genuinely hurt some of them.

Nigeria is its own complication. It is Ecowas’ largest economy by far, an oil exporter with a history of higher inflation and a currency that floats more freely than the CFA franc. 

Folding an economy that size into a currency union with much smaller, CFA-pegged neighbors raises hard questions about whose economic conditions the shared central bank would prioritize when setting policy.

More so, creating a currency is not the same as printing banknotes. 

A monetary union also requires countries to surrender part of their economic sovereignty and trust a shared institution.

That means joining countries would give up the ability to set their own interest rates or devalue their currencies. 

Devaluation—allowing a currency to lose value—can make exports cheaper and help an economy adjust after a shock, although it also raises import prices. Inside a monetary union, that tool disappears.

Those do not make a union impossible, but they increase the need for fiscal coordination and a regional stabilization fund able to help a member hit by a shock that others do not share.

So what’s actually different this time?

A few things have shifted the landscape heading into 2027:

A smaller, arguably more workable club. Burkina Faso, Mali, and Niger—the three military-led states that formed the breakaway Alliance of Sahel States—formally left Ecowas in January 2025. That’s a loss for regional unity, but from a pure economics standpoint, their exit could simplify the Eco project by removing countries whose political instability made convergence targets even harder to hit.

A phased rollout, not a big-bang launch. Rather than requiring all remaining member states to qualify at once, Ecowas leaders have now settled on launching with only the countries that already meet the convergence criteria, with the rest joining later once they catch up. This is a meaningful concession to reality. It swaps an all-or-nothing deadline for something closer to how the eurozone itself expanded gradually from 11 countries to 20.

Real legal groundwork. The bloc has registered the “Eco” trademark with the African Intellectual Property Organization, a small but concrete sign that this round of preparation is moving beyond communiqués. A dedicated Presidential Task Force, chaired with input from Côte d’Ivoire’s president, is expected to convene again before Ecowas’ December 2026 summit to iron out remaining sticking points, including how a future West African Central Bank would actually make decisions, and the thorniest question of all: whether Waemu’s CFA franc countries join the eco from day one, or later.

A more favorable economic backdrop. Ecowas leaders noted the region enters 2027 with declining inflation, lower public debt-to-GDP ratios, and a widening current account surplus across many member states, though they flagged that government budget deficits remain a real concern.

What the Eco could change

For businesses, the prize is lower friction. 

A single currency could remove repeated conversion fees, make prices easier to compare and reduce exchange-rate risk. A sudden currency movement would no longer turn a profitable cross-border order into a loss.

For households, transfers could become simpler and more predictable. Students, migrant workers and families could move money without navigating several exchange rates.

For investors, a credible Eco could create a larger financial space. 

Governments and companies might borrow from a broader pool of savings, while common standards could make investments easier to compare. This could deepen capital markets and attract investors who currently see West Africa as fragmented currency zones. 

Regional payment integration and the closer connection of capital markets were already embedded in the ambitions of the Revised Ecowas Treaty.

A shared central bank could strengthen monetary credibility where inflation has been high. An independent regional institution may be better placed to resist political pressure to print money. 

Broadly, the Eco could become an important West African building block for the African Continental Free Trade Area, or AfCFTA, which aims to reduce trade barriers and create a more integrated market covering every African country. 

Even when tariffs fall, businesses can still face costly currency conversions, payment delays and exchange-rate risk. 

A credible common currency would allow companies in participating countries to invoice customers, pay suppliers and compare prices in the same currency, making it easier to build regional supply chains, combine production across borders and achieve the scale needed to compete across Africa.

The Eco could also complement the Pan-African Payment and Settlement System, or PAPSS, which supports cross-border payments in African currencies. 

By reducing the number of currencies used within West Africa, the Eco could make regional transactions simpler and strengthen Ecowas as a commercial bloc within the wider AfCFTA market. 

It would not replace the need for better roads, ports, customs systems, electricity and consistent trade rules, but it could help turn Africa’s continental free-trade ambitions into faster, cheaper and more predictable transactions for businesses and consumers.

The benefits are clear, but success isn’t guaranteed. The gap between Waemu’s low-inflation, France-anchored economies and WAMZ’s larger, more volatile ones hasn’t disappeared just because three Sahel states left.

But for the first time in years, Ecowas is pairing its familiar 2027 pledge with a plan—phased entry, a registered trademark, an active task force—that looks less like déjà vu and more like actual homework being done. 

Whether that’s enough to finally get West Africa’s fabric traders down to one currency instead of three remains, as it has for 44 years, a story still being written.
