Keypoints:
- Debt servicing absorbs growing shares of government revenue
- Fiscal and monetary policy space continues to narrow
- WEF warns growth outlook remains fragile in 2026
SUB-SAHARAN Africa’s mounting public debt burden is tightening its grip on the region’s economy, constraining government spending, weakening investor confidence and limiting room for policy intervention, according to the World Economic Forum (WEF).
In its latest Chief Economists Outlook, the WEF warns that debt vulnerabilities have emerged as one of the most serious structural threats facing African economies in 2025 and into 2026, as governments divert scarce public resources from development priorities to loan repayments.
The assessment shows a notable decline in optimism among global economists on sub-Saharan Africa’s growth trajectory. Fewer respondents now expect moderate expansion, while a rising share forecast weak or uneven economic performance.
Rising public debt across sub-Saharan Africa is increasingly crowding out investment in infrastructure, healthcare and job creation. With borrowing costs elevated and fiscal space shrinking, economists warn the region’s economic outlook remains fragile despite easing inflation and tentative global recovery signals.
Debt servicing crowds out development
Over the past decade, many African governments expanded borrowing to finance infrastructure, social programmes and budget shortfalls, a trend that accelerated during the Covid-19 pandemic and subsequent global shocks.
However, higher global interest rates and weakening local currencies have sharply raised the cost of debt servicing. In several countries, interest payments now consume a substantial portion of government revenue, leaving limited funds for capital investment and long-term growth initiatives.
The WEF notes that while borrowing initially supported economic stability, the scale of current obligations has become a structural drag on productivity and development.
Limited fiscal and monetary flexibility
Although inflationary pressures have begun to ease in parts of the continent, policymakers remain constrained in their response options.
More than four-fifths of central bankers surveyed by the WEF expect interest rates to remain unchanged in the near term, reflecting concerns that further tightening could suppress growth, while easing could trigger capital flight or renewed inflation.
On the fiscal front, elevated debt levels have reduced access to affordable international financing. As a result, several governments have turned increasingly to domestic borrowing, raising concerns about crowding out private-sector credit and stressing local financial systems.
Households and businesses feel strain
The debt burden is also filtering through to households and businesses.
In an effort to stabilise public finances, governments across the region have introduced higher taxes and levies. While these measures help support debt obligations, they often dampen consumer spending and slow business expansion.
‘High public debt fuels higher taxes that squeeze households and small businesses, weakening demand, investment and job creation,’ the WEF report states.
Small and medium-sized enterprises — which account for the majority of employment in sub-Saharan Africa — are particularly vulnerable to rising costs and tighter access to finance.
External risks deepen uncertainty
The debt challenge is unfolding amid persistent global volatility.
Slowing global trade, geopolitical tensions and shifting capital flows continue to expose African economies to external shocks. For heavily indebted states, these pressures can rapidly translate into balance-of-payments stress, currency instability and rising refinancing risks.
The WEF cautions that without credible fiscal consolidation, improved debt transparency and stronger domestic revenue mobilisation, several economies could face prolonged periods of subdued growth.
Balancing reform and recovery
Despite the mounting pressures, economists say opportunities remain if governments can align fiscal discipline with growth-enhancing reforms.
Improving tax efficiency, strengthening debt management frameworks, deepening regional trade and directing borrowing towards productive sectors could help restore investor confidence and rebuild economic resilience.
However, the forum warns that such reforms will require difficult political choices at a time when living costs remain high and public tolerance for austerity is limited.
As the WEF concludes, sub-Saharan Africa’s future growth will depend less on access to new borrowing and more on how effectively existing debt is managed in an era of tighter global finance.
