The International Monetary Fund (IMF) Has Projected

The International Monetary Fund (IMF) has projected that Nigeria may overtake Algeria to become Africa’s third‑largest economy by 2026, with its gross domestic product (GDP) expected to reach approximately $334 billion at current prices.
According to the IMF’s World Economic Outlook (October 2025 edition), Nigeria was Africa’s fourth‑largest economy in 2025, trailing South Africa, Egypt, and Algeria, with an estimated GDP of about $285 billion By contrast, Algeria’s output is forecast to be around $284 billion in 2026, meaning Nigeria would surpass it to claim the third position on the continent. IMF analysts link Nigeria’s projected rise to several ongoing policy changes and structural reforms, including:Removal of the fuel subsidy aimed at reducing government burden and improving fiscal balance.
Exchange‑rate liberalisation intended to improve foreign exchange liquidity and attract investment. Fiscal adjustments efforts to strengthen government revenues and rein in deficits. Despite short‑term inflationary pressures stemming from these reforms, the IMF believes they will support medium‑term economic growth and resilience. Nigeria’s rebound in economic activity is also tied to:
Increased crude oil production, boosting export returns and government revenue. Improved foreign exchange liquidity, easing currency pressures and supporting trade and investment.
Together, these factors are projected to lift Nigeria’s GDP to about $334 billion in 2026, compared with Algeria’s approximately $284 billion, putting Nigeria ahead in nominal GDP terms.
South Africa is expected to remain Africa’s largest economy, with a GDP of around $443 billion. Egypt is forecast as the second‑largest, at about $399 billion. Nigeria is tipped to take third place with $334 billion. Algeria, previously third in 2025, is projected at $284 billion in 2026. The forecast underscores a shift in continental rankings linked to domestic reforms, currency movements, and structural resilience. Economists say that Nigeria’s progress toward third place is not just statistical it reflects broader policy efforts:
The liberalised exchange rate regime has improved confidence in the forex market. Fiscal reforms and subsidy removal are seen as critical to restoring macroeconomic balance. These moves have also contributed to positive revisions in Nigeria’s economic growth outlook the IMF recently raised its forecast for real GDP growth in 2026, reflecting stronger performance expectations.
Inflationary pressures remain elevated in the short term due to adjustment shocks.Continued dependency on oil revenue leaves Nigeria vulnerable to global price swings.
Structural reforms need sustained implementation to ensure growth resilience beyond 2026.
