Signal
The WAEMU banking system is profitable, well-capitalised by regional standards, and growing. According to Fitch Ratings’ 2025 assessment, the union’s banks have ridden a 6 percent regional GDP expansion to balance sheets that look healthier than they have in a decade.
Behind that headline, a quieter pattern has hardened. Sovereign debt issued by the eight WAEMU member states and held overwhelmingly within the union’s banking sector now accounts for roughly 30 percent of total bank assets. That exposure is equivalent to about three times the equity of those same banks. National concentration varies between 4 and 19 percent of assets depending on the country, with Ivorian banks particularly concentrated in the debt of their own sovereign.
Bank lending to the private sector has not collapsed. It has plateaued. Credit to the WAEMU economy grew 5.6 percent in 2025, after 4.5 percent in 2024. These figures represent improvements on a low base. They remain well below the rates seen in the late 2010s, and they do not match the financing needs of an economy running at 6.4 percent real growth. The configuration has a name: financial crowding-out. It is not new in West Africa. Its scale and persistence in the post-Covid period warrant fresh attention.
Reading
The mechanics are straightforward.
WAEMU member states have rebuilt their financing strategies around the regional debt market, in the wake of the 2022 reserve squeeze and the partial closure of international capital markets to several issuers. The regional market, operated through UMOA-Titres and the BRVM, raised nearly CFA 11,900 billion in 2025, about USD 21.6 billion. That is more than double the volume of three years earlier. Senegal alone tapped CFA 2,224 billion in 2025, a 123 percent increase year on year. The plan for 2026 is for member states to issue up to CFA 12,700 billion. Sovereign issuance has scaled rapidly. It has scaled into the same balance sheets that are also expected to finance the private economy.
The mathematics of this allocation favour the sovereign. WAEMU government securities carry a zero risk weight under the regional prudential framework. They consume no regulatory capital. They are eligible collateral for BCEAO refinancing operations, which provides banks with on-demand liquidity. They generate yields that, in the post-2022 monetary environment, have been competitive with the lending margins available on private sector loans, particularly when adjusted for default risk and operational cost. They require no collateral assessment, no land title verification, no debt enforcement litigation. None of the institutional friction that characterises private sector lending in the region. A treasury bill auction is processed on a screen. A loan to a Senegalese SME requires due diligence, collateral perfection, and the prospect of years in court if recovery becomes necessary.
The IMF, the World Bank and Fitch have all flagged the pattern. The IMF’s 2024 Selected Issues Paper on WAEMU banking risks documented the structural drift. Bank exposure to sovereigns has grown substantially, particularly since the 2020 pandemic financing surge. It is heavily concentrated in the home sovereign of each bank’s country of residence. Ivorian banks hold predominantly Ivorian government paper. Senegalese banks hold Senegalese paper. The cross-border diversification that a monetary union should mechanically produce is not, in practice, occurring. The result is a sovereign-bank nexus that is both intra-national and union-wide. Each member state is most exposed to its own banks. The regional banking system is collectively exposed to sovereign performance across the union.
For the private sector, the consequences are concrete and unevenly distributed. Lending to micro, small and medium enterprises has actually accelerated as a share of business loans. MSMEs received 52 percent of loans extended to businesses in 2024, up from 49 percent in 2023. MSME lending grew 13.5 percent compared to 3.8 percent for large corporates. The figure is sometimes presented as a success story. In a narrow sense, it is. The BCEAO’s SME charter has measurably increased SME access to formal credit. But the absolute volume of SME credit remains small relative to the financing needs of the regional economy. The growth rates flatter a base that started low.
For larger corporates, the natural counterparties for project finance, working capital lines and trade finance, the squeeze is sharper. Sovereign issuance is competing directly with corporate borrowing for the same banking system balance sheet capacity. Lending to large enterprises grew 3.8 percent in 2024, less than half the headline rate of credit growth and well below the rate of nominal GDP. Treasury directors at large WAEMU corporates report longer credit committee timelines, more conservative pricing, and a clear preference among bankers for collateralised short-term facilities over the multi-year tenors that capital expenditure programmes require. The squeeze is not absolute. It is selective. The selection criteria favour government over enterprise.
Implication
Three implications follow, each affecting a different constituency.
For governments, the trade-off is becoming acute. Heavy reliance on the regional debt market resolves the immediate financing problem. Senegal can place CFA 2,000 billion in a calendar year without testing international markets. But this transfers the cost to the private sector and embeds a future fragility into the banking system. Each new sovereign issuance crowds out private lending capacity by the amount it absorbs. It accumulates an exposure that, if any single sovereign required restructuring, would transmit losses directly into the regional banking system. The Common Framework experience in Ghana and Zambia shows what restructuring does to domestic financial sectors. The WAEMU has not been there. It is also not far from there, by the metric of bank-sovereign exposure.
For banks, the question is whether the current allocation is strategically durable. Holding 30 percent of assets in sovereign exposure, at three times equity, is a profitable position when sovereigns perform. It is a balance-sheet-threatening position when they do not. Fitch’s 2025 assessment noted that asset quality in WAEMU banks may be understated due to less conservative classification rules than international standards. Non-performing loan ratios stand around 8.5 percent on the books, possibly higher under IFRS-equivalent treatment. Banks adding sovereign exposure to balance sheets where the private credit book is already concentrated and partially impaired are not diversifying. They are doubling down on a single risk factor. The withdrawal of several French and other European banks from the WAEMU over the past five years has accelerated the consolidation of sovereign exposure into a smaller number of pan-African banks and regional players. This intensifies the concentration rather than diluting it.
For corporates and investors, the implication is that financing strategies built on the assumption of normalising bank credit conditions are mispriced. The squeeze is not a cyclical phenomenon awaiting the next BCEAO rate cut. It is a structural feature of the union’s current financing architecture. It will persist as long as sovereign issuance volumes remain elevated relative to banking system capacity. Corporates with alternatives, DFI lines, equity issuance, supplier finance, parent-company support, are using them. Those depending exclusively on regional bank credit are absorbing the squeeze in slower expansion plans, deferred investments, and tighter working capital cycles.
Projection
Three things to watch.
The first is the development of the regional capital market beyond bank intermediation. A genuinely deep BRVM corporate bond segment, with broader issuer participation and meaningful pension fund and insurance company demand, would provide the parallel channel that the banking system is currently failing to deliver. Initiatives are in motion. The launch of a new trading platform on 27 January 2026 is the most concrete recent development. Pension fund regulatory caps are easing across the region, mirroring trends in South Africa and Zambia where private equity allocation limits have been raised. But the development of a regional corporate bond market is a multi-year project, not a current solution.
The second is whether the BCEAO and the regional banking commission move on the macroprudential tools available to them. The 2022 Financial Sector Assessment Programme flagged targeted Pillar 2 capital surcharges as one option to discourage excessive sovereign concentration. The IMF’s 2025 Article IV consultation reiterated the recommendation. None of these tools has been activated at scale. The political constraint is straightforward: the same governments whose securities would be penalised are also the ones whose finance ministries would need to authorise the measures.
The third is the 2026 issuance trajectory itself. CFA 12,700 billion of planned regional issuance approaches the practical absorption limit of the banking system. If 2026 volumes match plan, the pressure on private sector credit will intensify. If they fall short, the question shifts to how member states close their financing gaps without a return to international markets at a cost they can absorb. Either outcome is informative.
The credit gap is structural because no single actor is responsible for it. It is a coordination failure across a system whose individual participants are behaving rationally. Coordination failures do not resolve themselves. They require coordinated action, which in this case means a combination of fiscal restraint, prudential adjustment and capital market development that none of the individual stakeholders can deliver alone.
