Top 10 African countries with the strongest investment prospects in latest 2026 ranking

Against this backdrop, Bloomberg Economics has ranked 19 African countries using an investment risk-o-meter that measures five factors likely to influence financial returns : economic strength, fiscal strength, institutions and governance, infrastructure, and external vulnerability. The methodology standardises indicators including economic growth, debt, political risk and foreign reserves into Z-scores, allowing Bloomberg to compare countries across different measures. The scores are then weighted to produce an overall risk rating, with a higher number indicating lower relative investment risk. Bloomberg Businessweek said the countries assessed account for about one-third of Africa’s economy, with the selection covering major economies as well as countries attractive to investors because of commodity wealth, financial hubs and business-tourism potential. For the purpose of this article, Business Insider Africa will focus on the top 10 African countries with the strongest investment ranking s in the report presented below. Mauritius leads as Nigeria makes biggest jump Mauritius topped Bloomberg Economics ’ latest investment risk ranking with a score of 0.6, followed by South Africa at 0.5. Egypt, Ghana, Botswana and Côte d’Ivoire formed the next group at 0.3, while Morocco scored 0.2. Nigeria ranked eighth with 0.1, ahead of Rwanda and Tanzania, which both recorded 0.0. Nigeria also recorded the biggest improvement among the countries assessed, climbing four places to eighth. Its economic strength score rose to 0.4, while fiscal strength stood at 0.6 and external vulnerability at 1.4. However, its institutions and governance score of -1.2 and infrastructure score of -0.5 remained areas of weakness. Mauritius’ move to the top came as South Africa slipped from first place in the 2025 ranking to second, with Bloomberg pointing to a moderate weakening in its growth outlook. Botswana also dropped two places as its growth outlook deteriorated, although its institutions and governance score of 1.5 remained one of the strongest among the countries assessed. The ranking also highlights how closely grouped many of Africa’s leading investment markets are, with six of the top 10 countries scoring between 0.1 and 0.3. Bloomberg’s research points to critical minerals, data centres, fertilizer, transport infrastructure, renewable energy, and oil and gas as major areas attracting capital across the continent. “ Risks vary substantially across countries and regions ,” said Kevin Latter, JPMorgan Chase’s senior country officer for sub-Saharan Africa. The assessment suggests that Africa’s investment opportunity is expanding, but countries will need to strengthen economic stability, infrastructure and institutions while reducing exposure to external shocks to convert that opportunity into sustained capital inflows.
