Africa Grew Faster in 2025 Than It Has in a Decade. It Is Still Falling Behind. The Gap Is Not a Headline Problem. It Is a Structural One.

Sub-Saharan Africa's economic performance in 2025 was, by several measures, genuinely strong. Regional GDP growth reached approximately 4.5 percent, the fastest pace recorded in over a decade. Inflation moderated across most of the region. Fiscal positions improved. Several large economies, including Ethiopia and Nigeria, began showing the results of difficult domestic reforms. On the surface, this is what stabilisation looks like, and credit is due for the policy discipline that produced it. But the IMF's April 2026 Regional Economic Outlook for Sub-Saharan Africa contains a second number that sits beneath the headline and changes the meaning of the first. Per capita income growth across the region is projected at 2.3 percent over the medium term. Across other emerging market and developing economies, the equivalent figure is 3.6 percent. That 1.3 percentage point difference compounds annually. Over a decade it becomes an unbridgeable distance. It means Africa's populations are improving their material conditions more slowly than populations elsewhere in the developing world, even as their economies post growth rates that attract optimistic commentary. The Distinction That Changes the Entire Narrative The distinction the IMF data forces is between expansion and transformation. An economy expands when more activity occurs within its existing structure. It transforms when the structure itself changes, when each unit of labour produces more, when capital allocates toward higher-productivity uses, when the composition of output shifts toward sectors that generate durable gains. Africa in 2025 expanded. The evidence that it transformed is considerably weaker. This is not a temporary deviation from a positive long-run trend. It is a persistent structural condition that the data has consistently confirmed across different growth cycles. The IMF's growth accounting for Sub-Saharan Africa shows that total factor productivity, the measure of economy-wide efficiency, contributed an average of only one-quarter of a percentage point to growth over the past 25 years. The rest came from more people working and more capital being deployed. Both of those inputs face hard limits. Labour force expansion eventually decelerates as demographics shift. Capital accumulation without productivity improvement produces diminishing returns. An economy that cannot raise what each worker produces cannot sustain the kind of growth that closes the gap with the rest of the world. The Pattern the Data Keeps Confirming The region's growth pattern deepens this problem. The IMF identifies a recurring dynamic in which expansion driven by commodity cycles or public investment fails to catalyse the private sector activity that would sustain growth beyond the boom period. When commodity prices rise, resource-exporting economies grow. When they fall, those economies contract. The economic structure that existed before the boom largely reasserts itself after it. This is why countries that posted strong numbers through repeated commodity cycles have not become structurally richer in ways that persist. The growth was real. The transformation was not. For resource-intensive economies specifically, the medium-term per capita income growth projection is 1.8 percent, further below the regional average. This reflects not only the commodity cycle trap but the documented failure of resource revenues to generate the kind of broad-based productive investment that converts extractive growth into structural change. The IMF notes explicitly that gains from resource sectors are often not widely shared across the population. That is a welfare observation, but it is equally a structural diagnosis. An economy in which growth is captured by a narrow extractive layer is not building the institutional and productive foundations that convergence requires. What This Means for East Africa Specifically The geography of this challenge matters specifically for East Africa. Tanzania is growing. The IMF projects 5.9 percent growth for 2025, with momentum continuing at 5.9 percent in 2026 and 6.1 percent in 2027. Those are strong numbers by any regional comparison. But the question that Tanzania's long-term trajectory depends on is not whether the economy can sustain 6 percent growth. It is whether 6 percent growth is producing the kind of structural change that raises productivity, diversifies the export base, and reduces the economy's vulnerability to external shocks. Growth anchored in tourism receipts, commodity exports, and public infrastructure spending is real growth. It is not, without deliberate structural intervention, transformation growth. The Reform Arithmetic the IMF Lays Out The IMF is direct about what the data demands. Closing half the gap with emerging markets in foundational reform areas including governance, business regulation, and external sector openness could raise regional output by up to 20 percent over 5 to 10 years. The mechanism is not mysterious. Better governance lowers the cost of doing business, reduces the diversion of productive capital toward compliance and rent extraction, and strengthens state capacity to deliver the public goods on which private investment depends. Structural reforms that improve productivity produce compounding gains because each improvement raises the base on which future growth occurs. The 1.3 percentage point annual gap between Africa's per capita growth and the developing world average is not a rounding error in a development statistics report. It is the arithmetic of a structural divergence that, if it persists, means African economies become relatively smaller in the global income distribution with every passing decade, even while they post growth rates that generate positive headlines. The continent holds extraordinary natural capital, a rapidly growing labour force, and increasing volumes of institutional knowledge about what reform actually requires. What it has not yet consistently done is convert those inputs into the kind of productivity growth that changes an economy's position in the global hierarchy. Africa is growing. That is true and it matters. The harder truth, which the IMF data states plainly, is that growing and catching up are not the same thing.
