ECOWAS Takes Phased Route to Eco, Targets 2027 Rollout

ECOWAS has adopted a phased approach to its planned common currency, the eco, with an initial rollout set for 2027 for countries that meet macroeconomic convergence criteria. The decision comes more than four decades after the bloc first moved toward a shared currency.

Plans to introduce the eco in 2003 were repeatedly delayed. Members failed to meet the convergence criteria at the same time and on a consistent basis. The new phased route is meant to keep momentum without weakening macroeconomic discipline.

External shocks keep disrupting convergence

The bloc’s convergence push is exposed to forces beyond national control. A sharp rise in global interest rates raises borrowing costs and debt-service payments across member states, even when governments keep prudent policies. That can create wide divergences inside ECOWAS.

The Nigerian naira, the currency of the bloc’s largest economy, depreciated by more than 50% at the peak of the US Federal Reserve’s post-pandemic tightening cycle. That sharply raised the domestic-currency cost of external debt and imported goods, setting off a negative loop of exchange-rate weakness, inflation and fiscal stress.

Convergence is also dynamic. Meeting the criteria at one point does not guarantee that compliance will last. ECOWAS members differ widely in export diversification, productivity, industrialisation, fiscal capacity and financial-market development. The bloc needs mechanisms that help countries return to convergence after divergence.

Fiscal federalism before a single currency

The stronger argument is for fiscal federalism before monetary integration. A regional fiscal authority could set common rules, coordinate taxation, mobilise regional revenues, finance cross-border infrastructure and run stabilisation mechanisms.

Such risk-sharing would make the eventual loss of independent monetary policy and exchange-rate adjustments less disruptive. It would also help a region where some countries run flexible exchange rates while others use the CFA franc, which is pegged to the euro.

ECOWAS currently lacks a robust mechanism to address asymmetric shocks. A common fiscal capacity could redistribute resources to economies in temporary distress and finance countercyclical investment in productive capacity and cross-border infrastructure.

What it means for Nigeria and regional markets

ECOWAS also faces fragmented domestic capital markets. Small, illiquid sovereign-debt markets leave member states exposed to the original sin of borrowing in foreign currencies and slow the development of reliable yield curves. Fiscal integration could create the scale, liquidity and institutional infrastructure for a deeper regional financial market, with common benchmarks across maturities and more transparent capital costs.

The incremental nature of fiscal integration may also make monetary integration less politically threatening. Monetary integration requires a conspicuous transfer of sovereignty. Fiscal integration can proceed step by step, with benefits accruing gradually. The approach could also advance the African Union’s Agenda 2063, which seeks deeper continental economic integration.

For Nigerian businesses, the immediate signal is that ECOWAS policy work is shifting toward fiscal rules, regional capital-market benchmarks and shared institutions before any single currency. The naira’s role in the bloc and Nigeria’s position as its largest economy will remain central to that debate.
