The International Monetary Fund (IMF) has raised its 2026 economic growth forecast for sub-Saharan Africa to 4.5% from 4.3% in April, citing resilient economic activity and domestic reforms, but warned that accelerating inflation, high borrowing costs and declining foreign aid threaten the region's recovery.
In its updated regional economic outlook released on October 15, the IMF projected that median inflation would rise from 3.4% in 2025 to 4.3% in 2026 and 5% in 2027, reversing its April expectation that price pressures would peak this year before easing.
The revised forecast brings expected 2026 growth into line with the estimated 4.5% expansion in 2025, which the IMF described in its April outlook, Hard-Won Gains Under Pressure, as the fastest pace in more than a decade. The upward revision therefore indicates greater resilience rather than an acceleration in growth.
The improved outlook reflects adjustments to global energy supply disruptions, private-sector adaptation and domestic reforms, although economic performance varies substantially between commodity exporters and import-dependent economies.
Inflation threatens economic recovery
Zeine Zeidane, director of the IMF's African Department, told Reuters that controlling inflation remained a priority despite the stronger growth outlook.
"Monetary policy has to remain data dependent, but the focus should be on making sure that you bring inflation to your target," Zeidane said.
The IMF indicated that further monetary tightening "may be needed" in most countries, although the appropriate response depends on domestic inflation and economic conditions.
Zeidane also cautioned in an interview with AFP that economic expansion remained insufficient to deliver rapid improvements in living standards.
"Our view is that per capita growth today remains quite weak," he said.
"It would take the region nearly 50 years to double its income. By comparison, Southeast Asia managed to double its income per capita in 15 years."
The comparison illustrates the region's slow pace of income convergence. Population growth continues to dilute gains in output per person, while weak productivity and limited formal-sector employment constrain incomes.
Debt servicing and borrowing costs squeeze budgets
Interest payments now absorb approximately 12% of government revenue across sub-Saharan Africa, limiting resources for infrastructure and public services.
External financing conditions have deteriorated despite some improvement in African sovereign risk premiums. The yield on 10-year US Treasury bonds increased from 4% in late February to 5.2% at the end of September, raising an important benchmark for international borrowing costs.
"Despite compressing the spread, the cost of borrowing could continue to rise," Zeidane told Reuters.
African sovereign borrowing costs depend on both underlying international interest rates and the additional premiums investors demand for holding individual countries' debt. Narrower risk premiums therefore do not necessarily translate into cheaper financing when global benchmark yields rise.
The fund also identified delays in sovereign debt restructuring as an obstacle to recovery. Ethiopia, Ghana and Zambia have made progress through different restructuring processes, but prolonged negotiations have complicated economic adjustment and, in some cases, access to IMF financing.
The IMF is developing standardised restructuring documents and improved information-sharing mechanisms to accelerate future negotiations.
Commodity exporters gain as importers face widening deficits
Higher global energy prices are expected to widen the divide between commodity exporters and import-dependent economies.
The IMF's updated projections show oil exporters' current-account surpluses rising to 4.4% of gross domestic product (GDP), compared with 1.6% in its earlier projections, reflecting stronger export revenues.
By contrast, projected current-account deficits in non-resource-intensive economies have widened to 5.8% of GDP from 3.4% in the earlier outlook, reflecting higher import costs.
These figures describe external balances, rather than government budget positions, and illustrate how higher commodity prices can improve export earnings in some economies while increasing foreign-exchange requirements in others.
The IMF expects bilateral development aid to fall by a further 12% in 2026 after contracting by approximately 25% in 2025, adding to financing pressures.
Climate shocks pose further risks
IMF simulations suggest that an El Niño-related shock could reduce regional economic growth by 0.5 percentage points and increase inflation by 2.6 percentage points in 2027 through disruptions to agriculture and food supplies.
Under such a scenario, Southern Africa could face drought and disruptions to hydroelectric generation, while parts of East Africa could experience flooding and agricultural losses.
"We are very concerned because it could have a major effect on agricultural production but also on electricity generation, particularly in southern Africa," Zeidane told AFP.
The IMF warned that diminished financial buffers had left governments poorly positioned to withstand another major disruption.
"That leaves the region with little room to absorb another shock," Zeidane told reporters, according to Associated Press.
