The International Monetary Fund (IMF) has projected sharply contrasting economic fortunes for Africa’s two largest economies, forecasting Nigeria to grow at 4.1% in 2026 while South Africa limps behind at just 1.0%.
The forecast, contained in the IMF’s April 2026 Global Financial Stability Report and monitored by Spear News Nigeria, reflects a broader but uneven slowdown across Sub-Saharan Africa, where regional growth is expected to ease from 4.5% in 2025 to 4.3% in 2026.
While Nigeria’s outlook remains relatively robust despite a recent downgrade, South Africa’s anaemic projection places it among the weakest performers on the continent, trailing even Germany’s expected 0.8% growth.
Nigeria: Downgraded but Still Ahead
The IMF revised Nigeria’s 2026 growth forecast downward by 0.3 percentage points from its January 2026 projection of 4.4%, settling at 4.1%.
Explaining the move, Deniz Igan, Deputy Chief of the Macro-Financial Division in the IMF’s Research Department, said Nigeria finds itself caught between two opposing forces.
“Turning to Nigeria, we have revised growth down by 0.3 percentage points to 4.1 per cent in 2026. This reflects a balance of two forces: higher fuel and fertilizer prices, along with increased shipping costs, which are expected to weigh on non-oil activity, and some offset from higher oil prices,” she said.
The downgrade means Nigeria’s growth will be slower than previously hoped, though elevated global oil prices—driven by escalating US-Iran tensions—are expected to provide a partial buffer.
South Africa: Structural Challenges Bite
In stark contrast, South Africa is projected to grow at just 1.0% in 2026, a figure that highlights deep structural weaknesses in Africa’s most industrialised economy.
Unlike Nigeria, South Africa is a net oil importer, meaning the same war-driven surge in energy prices that partially cushions Nigeria delivers a severe terms-of-trade shock to Pretoria.
The IMF noted that declining foreign aid and softer non-oil commodity prices are adding pressure across the region, with bilateral support dropping by 16% to 28% in 2025—a trend expected to persist and disproportionately affect countries like South Africa with thinner fiscal buffers.
Regional Context: A Slowing Continent
Sub-Saharan Africa’s projected slowdown from 4.5% to 4.3% masks wide disparities. While Nigeria and others face headwinds, the region still outperforms the global average, which the IMF expects to decline from 3.4% in 2025 to 3.1% in 2026.
By comparison:
· India leads major economies with 6.5% growth in 2026.
· The United States is projected at 2.3%.
· The United Kingdom lags at 0.8%.
· Germany is expected to recover modestly to 0.8%.
What This Means for Policy
The IMF emphasised that tighter monetary policy remains essential across the region. For Nigeria, this means sustaining the Central Bank’s current stance, with the benchmark interest rate at 26.50% and inflation hovering around 15.06% as of February 2026.
“Overall, the balance is expected to weigh on growth in 2026, with some recovery projected in 2027,” Igan said.
For South Africa, the 1.0% forecast adds pressure on policymakers to accelerate structural reforms, particularly in energy and logistics, where persistent failures have crippled economic activity.
Looking Ahead
The IMF’s mixed forecast underscores a fundamental reality: Africa’s economic future is no longer a single story. Oil-exporting nations like Nigeria, despite their own challenges, are better positioned to weather current global shocks than import-dependent economies like South Africa.
Whether either nation can beat these projections will depend on how effectively they navigate rising fuel costs, supply chain disruptions, and the lingering effects of geopolitical instability in the Middle East.
