West African leaders have recommitted to a shared currency by 2027, but the framework for its launch remains incomplete.
The Economic Community of West African States, or ECOWAS, announced after a summit in Sierra Leone on Sunday that the new currency, called the ECO, would roll out in phases. Only member states that meet strict convergence criteria will qualify for the first wave. Those criteria include caps on inflation, sustainable debt levels and stable exchange rates, an approach that echoes the Maastricht criteria that preceded the euro.
Beyond the phased structure, however, several foundational questions remain unresolved. Among them are the future central bank's mandate, the structure of decision-making and the order of country participation.
On the question of monetary governance, officials have not decided whether the central bank will target inflation, float against major currencies or adopt a hard peg.
Turning to the region's existing currency arrangements, the CFA franc presents another unresolved issue. Members of the West African Economic and Monetary Union, or UEMOA, currently peg their currency to the euro with a guarantee from the French treasury. Transitioning to the ECO would remove that guarantee, and no regional reserve-pooling mechanism or stabilization fund has been proposed to replace it.
The ECO's design also does not include a fiscal transfer mechanism or automatic stabiliser, a feature common in other currency zones.
Compounding these economic uncertainties is the geopolitical landscape. Burkina Faso, Mali and Niger have withdrawn from ECOWAS but remain within the UEMOA monetary union, adding further complexity to the rollout.
On the trade side, intra-regional commerce accounts for roughly twelve percent of total trade. Eliminating currency conversion fees could boost trade, but that depends on operationalizing the central bank's settlement systems, reserve requirements and lender-of-last-resort functions, none of which have been finalized.
A task force is scheduled to meet before the December 2026 summit to address the outstanding issues.
