Prior state
The three states left the regional bloc, formed a confederation with a common import levy, a joint force, and a projected investment bank, nationalised or renegotiated major mining assets, and replaced Western security partners — while remaining inside the monetary union whose central bank holds their reserves and whose currency has a fixed external peg. Jihadist economic pressure on Bamako, including sustained interdiction of fuel convoys, has demonstrated the fragility of their supply lines.
Material change
At least one confederation member issues its own currency, or the confederation announces a common currency with a conversion date. Seigniorage, reserve management, and convertibility move from a shared regional institution to national or confederal control, and the fixed external peg that has governed the region's monetary policy since decolonisation is broken for part of it.
Why now
The transition period following the bloc exit closes, removing the last procedural reason for delay; the confederal levy and bank give a nominal fiscal and institutional base; and financing needs for security spending cannot be met from markets, from the regional central bank's advance limits, or from mining revenue alone. The rhetorical commitment has an accumulating credibility cost that becomes hard to defer past the confederation's own institutional timetable.
Mechanism and resistance
Execution requires printing, distributing, and defending a new unit while the old one circulates freely across porous borders, and requires access to reserves the regional central bank holds. Resistance comes from the coastal members of the union, which would face the contagion, from importers and merchants who price in the existing unit, from the near-certainty of immediate depreciation and imported inflation in landlocked economies with high import dependence, and from the regional central bank's ability to make separation expensive.
Consequences
Urban salaried workers and importers lose immediately through depreciation; the state gains an inflation tax and financing autonomy; gold, sold in dollars, becomes the effective reserve anchor and increases the leverage of the buyers of that gold. Remaining monetary-union members face a credibility test for a peg that has survived every previous political shock, and the coastal states' cost of capital reprices. For the wider region it is the most consequential institutional break since the bloc's founding.
End state
The central Sahel enters 2028 either with a new monetary regime and an inflation problem, or with the announcement made and the conversion still pending.
Observable test
An official conversion date and legal-tender instrument, or new notes in circulation; statements from the regional central bank on membership and reserve treatment; the parallel exchange rate between the new unit and the existing one in Bamako and Ouagadougou markets.
Disconfirming sign
Continued ordinary circulation of union banknotes and continued participation in the regional central bank's governance through the whole year.
