IMF: Nigeria to overtake Algeria as Africa’s third-largest economy in 2026

The International Monetary Fund's latest economic projections reveal a significant reshuffling of Africa's economic pecking order, with Nigeria poised to overtake Algeria as the continent's third-largest economy by 2026. This forecast underscores a dramatic reversal of fortunes for West Africa's largest economy, which has spent years recovering from oil-price volatility and macroeconomic instability. The implications for European investors tracking African markets are substantial—and multifaceted.

For the past decade, Algeria maintained its position as Africa's third-largest economy, buoyed by substantial hydrocarbon revenues and a population exceeding 45 million. However, structural constraints—including over-reliance on oil and gas exports, limited economic diversification, and subdued non-energy sector growth—have constrained Algeria's long-term expansion prospects. Meanwhile, Nigeria's economy, despite persistent security challenges in the north and infrastructure deficits, has demonstrated surprising resilience and growth potential that is finally translating into nominal GDP gains.

Nigeria's trajectory reflects several converging factors. First, the naira's stabilization following the Central Bank's 2023 monetary policy reforms has reduced currency-depreciation headwinds that previously inflated GDP measurements when converted to US dollars. Second, the government's removal of fuel subsidies and rationalization of the exchange rate regime—though domestically painful—have improved macroeconomic credibility with international investors. Third, Nigeria's non-oil sectors, particularly technology, telecommunications, and financial services, are expanding at double-digit rates, diversifying the economy beyond petroleum dependence.

For European investors, this shift carries both opportunity and strategic importance. Nigeria's consumer market of over 220 million people remains Africa's largest, and the IMF's projection signals growing investor confidence in the nation's medium-term stability. This translates into potential entry points in fintech, renewable energy, agribusiness, and manufacturing—sectors increasingly attractive to European capital seeking exposure to Africa's digital economy.

However, the headline figure warrants nuance. While Nigeria's nominal GDP may surpass Algeria's, per-capita income tells a different story. Algeria's population of 45 million versus Nigeria's 223 million means per-capita wealth remains heavily concentrated in North Africa. European investors must distinguish between aggregate economic size and underlying consumption capacity, purchasing power, and market accessibility—critical factors often obscured by headline GDP rankings.

Algeria's relative economic stagnation also presents indirect risks for European investors. North Africa, historically an entry point for European firms into Africa, faces growth slowdown. This may incentivize European capital to rotate southward and westward, increasing competition for deals across Nigeria, Kenya, Ghana, and Ethiopia. Valuation multiples in established West African hubs could compress as capital flows diversify.

The IMF projection also reflects Nigeria's structural demographic advantage. With a median age below 20 and an urbanization rate climbing toward 55 percent, Nigeria possesses a young, increasingly educated workforce—attractive for labor-intensive manufacturing and high-growth sectors. This demographic bonus, if properly harnessed through education and skills development, could sustain Nigeria's economic outpacing of Algeria well beyond 2026.
