Bold claim first: debt is shaping Africa’s economic fate more than almost any other single factor, and the numbers tell a striking story about how governments, not households or businesses, are driving the risk. But here's where it gets controversial: the real risk isn’t just that debt exists, it’s that most African nations carry most of their burden as sovereign debt, with limited spillover from private borrowing. That distinction changes how policymakers should respond and who bears the cost.
Debt has emerged as a defining economic pressure for many African governments. From rising borrowing costs and weakening currencies to shrinking fiscal space and mounting repayment obligations, several countries across the continent are trying to finance development without tipping into distress.
Over the past decade, governments have borrowed heavily to fund infrastructure projects, cover budget deficits, respond to pandemic shocks, and address security challenges. With global interest rates staying high and concessional financing becoming harder to secure, the cost of servicing these debts has risen noticeably.
Global debt levels remain near record highs, according to the Institute of International Finance’s Global Debt Monitor data for the fourth quarter of 2025. Visual Capitalist’s analysis suggests that several advanced economies now carry total debt loads above 300% of GDP, meaning combined household, corporate, and government borrowing exceeds more than three years of economic output. In order of overall burden, the top global debt ratios include Hong Kong (380%), Japan (372%), Singapore (347%), France (326%), and Canada (315%). In these economies, private sector borrowing—a sizable slice of total debt—plays a major role.
Here are the 10 African nations with the highest total debt-to-GDP ratios, based on the latest available figures.
What stands out
At the apex is Senegal, with debt at roughly 156% of GDP, where government borrowing dominates and household leverage is comparatively low. This pattern—sovereign debt driving total exposure—also appears in Zambia (about 120%) and Mozambique (about 118%), where public debt is the principal risk.
By contrast, South Africa (about 149%) and Tunisia (about 143%) show more balanced debt profiles, with notable levels of household and corporate borrowing that reflect more mature financial markets. Morocco (about 124%), Rwanda (about 113%), Egypt (about 102%), and Kenya (about 100%) sit in the mid-range, characterized by a mix of moderate government borrowing and rising private-sector leverage, though public debt remains the dominant driver.
Across Africa, unlike in many highly developed economies where corporate and household debt often dominate, the debt burden here is predominantly sovereign. In most of the countries listed, government debt accounts for more than half of total liabilities.
This sovereign-focused structure leaves many African economies especially vulnerable to exchange-rate swings, rising global borrowing costs, and commodity price shocks, underscoring why currency stability and prudent public finance management are critical to sustaining growth.
