IMF Forecasts Nigeria to Become Africa’s Third-Largest Economy by 2026

The International Monetary Fund (IMF) has projected that Nigeria will ascend to become Africa’s third-largest economy by 2026, with an estimated Gross Domestic Product (GDP) of $334 billion, surpassing Algeria in the process.

According to the IMF’s World Economic Outlook data, Nigeria was ranked fourth on the continent in 2025 with a GDP of about $285 billion, behind South Africa, Egypt, and Algeria.

The IMF attributes Nigeria’s anticipated climb to several factors: rising oil output, improved foreign exchange liquidity, and the continuation of key economic reforms. These include the removal of fuel subsidies, the liberalisation of the exchange rate, and fiscal policy adjustments. While these measures are expected to spur medium-term growth, they have also contributed to short-term inflationary pressures.

Algeria’s economy is projected to reach $284 billion in 2026, placing it behind Nigeria if current trajectories hold. South Africa is forecast to retain its position as the continent’s largest economy with a $443 billion GDP, followed by Egypt at $399 billion.

Nigeria’s economic ranking has seen volatility in recent years due to currency devaluation, GDP rebasing, and broader macroeconomic issues. However, the IMF has recently upgraded Nigeria’s 2026 growth forecast to 4.4%, up from 4.2%. The World Bank has also revised its projection upward to 4.4% from 3.7%.

Globally, the IMF projects that Nigeria will be among the top 10 contributors to world GDP growth in 2026, accounting for 1.5%. China is expected to lead with 26.6%, followed by India (17%) and the United States (9.9%).

Reacting to the IMF’s analysis, Tesla CEO Elon Musk remarked, “The balance of power is changing.”

Analysts note that despite ongoing domestic and international headwinds, Nigeria’s consumption-driven economy continues to fuel expansion in key sectors such as energy, services, telecommunications, and trade, reinforcing its standing among emerging markets.
