IMF Forecasts Nigeria to Surpass Algeria as Africa's Third-Largest Economy by 2026

The International Monetary Fund (IMF) has indicated that Nigeria could soon become the third-largest economy on the African continent, with its Gross Domestic Product (GDP) anticipated to reach $334 billion in 2026. This projection suggests Nigeria will surpass Algeria in economic standing.

According to the fund's World Economic Outlook report from October 2025, Nigeria's GDP stood at approximately $285 billion at current prices, ranking it fourth in Africa behind South Africa, Egypt, and Algeria for 2025.

The IMF attributes Nigeria's projected economic advancement to several factors, including a rise in oil production, enhanced foreign exchange (FX) availability, and the positive effects of ongoing economic reforms. These reforms, such as the removal of fuel subsidies, liberalization of the exchange rate, and fiscal adjustments, are designed to foster medium-term growth, notwithstanding immediate inflationary pressures.

Nigeria's GDP is forecast to climb to around $334 billion, placing it ahead of Algeria, whose economic output is estimated to be $284 billion for the same year.

IMF forecasts show a significant shift by the review year, with Nigeria's economy expected to maintain its current resilience and demonstrate a robust growth outlook. South Africa is anticipated to continue leading the continent's economies with a projected GDP of $443 billion in 2026, followed by Egypt at $399 billion.

In 2025, South Africa was projected to hold its position as Africa's largest economy with a GDP of $426 billion, with Egypt following at $349 billion. Algeria was ranked third, with an estimated GDP of approximately $288 billion. Nigeria's economic ranking has seen fluctuations in recent years, influenced by currency devaluations, economic reclassifications, and broader macroeconomic challenges impacting key African economies.

Earlier in the year, the IMF revised Nigeria's 2026 economic growth forecast upwards to 4.4 percent, an increase from its earlier estimate of 4.2 percent. The World Bank has also raised its growth projection for Nigeria for 2026 to 4.4 percent, up from a forecast of 3.7 percent made in mid-2025.

Last week, the IMF projected that Nigeria would contribute 1.5 percent to global real GDP growth in 2026, positioning the country as the sixth-highest contributor and placing it among the top 10 globally. This standing puts Nigeria ahead of several developed and emerging economies, including Brazil (1.5 percent), Vietnam (1.6 percent), Saudi Arabia (1.7 percent), and Germany (0.9 percent).

China is expected to maintain its status as the largest contributor to global economic growth, accounting for 26.6 percent, followed by India with 17.0 percent, the United States with 9.9 percent, Indonesia with 3.8 percent, and Türkiye with 2.2 percent.

China and India are projected to be responsible for 43.6 percent of the total global economic growth this year. The IMF report also highlighted the dominance of the Asia Pacific region, which was expected to contribute nearly 50 percent of the overall global economic expansion, reflecting sustained economic momentum in the region.

Commenting on the IMF report, Elon Musk, CEO of Tesla, remarked, "The balance of power is changing."

Sources indicate that Nigeria's real growth projection is expected to remain around 3-4 percent despite current challenges. The country's consumption- driven growth is supporting expansion in the energy, services, telecommunications, and trade sectors.

This economic ranking also underscores Nigeria's role as a significant growth driver among emerging economies and its notable resilience, even amidst prevailing domestic and global economic uncertainties. The IMF report illustrated how India and China are increasingly becoming the primary engines of global economic growth.

The Eurozone as a whole is expected to contribute two percent to global growth. Advanced economies collectively are projected to expand by 1.8 percent, while emerging markets are anticipated to grow by 4.2 percent.
