Sub-Saharan Africa’s economy is showing greater resilience than expected, but rising inflation, expensive borrowing and shrinking financial safety nets threaten to undermine that progress, the International Monetary Fund (IMF) has warned.
The fund has raised its 2026 growth forecast for the region to 4.5%, up from 4.3% projected in April, pointing to adjustments in global supply chains and domestic economic reforms. Yet the improved outlook comes with a growing concern: inflation is now expected to accelerate rather than ease as previously anticipated.
Median inflation across the region is projected to rise from 3.4% in 2025 to 4.3% in 2026, before reaching 5% in 2027. In April, the IMF had expected inflation to peak at 5% this year and subsequently decline.
The revised outlook has strengthened the case for tighter monetary policy in many countries. The fund said most economies in the region may need further interest-rate increases to bring inflation under control.
“Monetary policy has to remain data dependent, but the focus should be on making sure that you bring inflation to your target,” Zeine Zeidane, director of the IMF’s African Department, said.
The warning marks a firmer stance than the fund’s earlier assessment, which described the policy challenge as a difficult balancing act between competing economic priorities.
Borrowing costs threaten already stretched budgets
Debt servicing remains a major obstacle for African governments struggling to preserve public spending while managing financial obligations. Interest payments now absorb around 12% of government revenue across the region, leaving less room for investment in infrastructure, public services and development programmes.
Global financial conditions are adding to the strain. The yield on the US 10-year Treasury bond climbed from 4% in late February to 5.2% by the end of September, increasing the cost of borrowing for governments worldwide.
Although sovereign risk premiums have narrowed, the IMF cautioned that African countries could still face higher financing costs.
“Despite compressing the spread, the cost of borrowing could continue to rise,” Zeidane said.
Debt restructuring presents another challenge. Lengthy negotiations can delay access to IMF financing, deepen financial distress and make the economic adjustments required to stabilise public finances more painful.
Ethiopia, Ghana and Zambia have all made progress in restructuring their debts, but their experiences highlight how drawn-out the process can become.
The IMF is seeking to accelerate future negotiations through a new restructuring framework and standardised memoranda of understanding. It is also offering to help creditors and debtor governments exchange information more effectively, with the aim of reducing delays.
Commodity exporters pull further ahead
Economic conditions are becoming increasingly uneven across sub-Saharan Africa, with countries benefiting from natural resources gaining ground while others face widening external financing gaps.
Oil-exporting economies are expected to see their current-account surpluses rise to 4.4% of gross domestic product, compared with 1.6% previously. By contrast, countries less reliant on natural resources are projected to record current-account deficits of 5.8% of GDP, up from 3.4%.
The widening divide leaves import-dependent economies particularly vulnerable to external shocks, higher import bills and limited access to affordable financing.
Foreign assistance is also becoming less reliable. Bilateral aid to the region is forecast to decline by another 12% in 2026, following an estimated drop of roughly 25% in 2025. The reduction threatens to add pressure on governments already dealing with tight budgets and rising development needs.
El Niño emerges as another economic threat
Climate risks have become a more prominent concern since the IMF released its previous regional outlook in April. The potential return of El Niño could disrupt agricultural production, push food prices higher and intensify food insecurity in vulnerable countries.
The fund’s simulations suggest that a climate shock of this kind could reduce regional economic growth by half a percentage point and raise inflation by 2.6 percentage points in 2027.
Such an outcome would compound existing pressures, particularly in economies where households are highly exposed to food-price increases and governments have limited resources to cushion the impact.
“Things could get worse than what we have in the outlook,” Zeidane said.
The IMF said it remains prepared to provide emergency financing through its 18 active country programmes if conditions deteriorate.
For now, the region’s stronger growth projection offers some reassurance. But the combination of persistent inflation, mounting debt costs, declining aid and climate uncertainty leaves little room for complacency. The central challenge for African economies will be turning their current growth momentum into lasting stability before those pressures become harder to contain.
