West Africa completes monetary consolidation and issues sovereign debt on its own terms

Prior state
West African monetary arrangements had been split for over a century between a currency union with an external anchor inherited from colonial arrangements and a set of independently floating national currencies, with a regional single-currency project repeatedly scheduled and repeatedly postponed. Regional sovereigns borrowed in foreign currency at spreads driven by external conditions, and restructurings were negotiated with creditor groups formed elsewhere.
Material change
Consolidation is completed: a single regional currency covering the union states and the large floating economies, an operating regional central bank with genuine reserve capacity, and — more consequentially — a functioning regional market in local-currency sovereign debt held predominantly by regional pension funds, insurers, and banks. Member states borrow long in their own money for the first time, and the region's restructuring practice is set by its own institutions.
Why now
The external anchor loses its remaining rationale once the region's trade is predominantly intra-African and Asian rather than European, a crossing that occurs in the years before this decade. Domestic institutional savings reach the depth required to absorb local-currency issuance, driven by the maturing of pension systems established decades earlier for the region's large working-age cohorts. Successive postponed target dates arrive against a generational turnover in the political and central-banking elite that had defended the inherited arrangement.
Mechanism and resistance
Consolidation proceeds through the existing union's institutions absorbing the larger economies rather than by building anything new, which is why it succeeds where earlier attempts failed. Resistance comes from the anchor's guarantor and from the domestic beneficiaries of the old arrangement; from smaller members fearing Nigerian dominance of a shared monetary policy; from importers and holders of foreign-currency assets; and from the genuine macroeconomic problem of a single policy for economies with very different fiscal positions and oil exposure. Early years include at least one serious convergence crisis and probably a temporary suspension of a member's participation.
Consequences
Borrowing costs fall and maturities lengthen for members that maintain discipline, and the region gains the capacity to finance long-horizon infrastructure without foreign-currency mismatch. Regional banks, insurers, and pension funds become large institutional investors and a political constituency for stability. Intra-regional trade rises as currency friction disappears. Adjustment costs fall on members that lose the exchange-rate instrument and must adjust through wages and fiscal policy, which produces real hardship in at least one member during the decade. The wider significance is that a large low- and middle-income region moves from being a rule-taker in sovereign finance to writing its own rules, which changes how similar regions elsewhere approach the question.
End state
A single West African currency and central bank are operating, member sovereigns fund themselves predominantly in local currency held by regional institutions, and restructuring practice is regionally rather than externally set.
Observable test
A single currency is in circulation across the member states with an operating regional central bank, and the share of member sovereign debt denominated in the regional currency and held by regional institutions is the majority of outstanding issuance.
Disconfirming sign
The target date is postponed again, the inherited anchor persists, and members continue issuing predominantly in foreign currency to external holders.
