Public debt is often measured against the size of a country’s economy through the debt to GDP ratio. While this indicator helps assess the scale of government borrowing relative to economic output, the bigger concern is how much that debt costs to service and what it leaves available for development. Across Sub Saharan Africa (SSA), recent debt trends show how borrowing, economic growth and restructuring can produce very different outcomes. According to Cytonn’s SSA Eurobonds Performance 2026 Report, Senegal’s public debt to GDP ratio declined to 130.2% in 2025 from 132.4% in 2024, while Zambia’s ratio fell to 86.0% from 125.2%. Ghana also recorded a significant decline, with its ratio dropping to 48.8% from 66.4%. In contrast, Ethiopia’s ratio increased to 43.1% from 33.4% over the same period.
These movements reflect different economic circumstances. Senegal’s debt burden remains elevated following the discovery of previously undisclosed government liabilities, which exposed weaknesses in public financial reporting and increased financing pressures. Although the country narrowed its fiscal deficit in 2025, its high debt obligations continue to limit its fiscal flexibility. Zambia’s decline was largely supported by external debt restructuring, including changes to its Eurobond obligations, alongside fiscal adjustment under its IMF supported programme. Ghana’s improvement similarly reflected domestic and external debt restructuring, stronger nominal economic growth and improved fiscal performance. However, lower debt ratios do not necessarily mean that both countries have fully overcome their debt challenges, as continued fiscal discipline remains necessary.
Ethiopia’s rising ratio, meanwhile, reflects persistent fiscal and external financing pressures, limited revenue capacity and foreign exchange constraints. Its previous Eurobond default further illustrates how difficulties in meeting repayment obligations can restrict access to international capital markets and complicate future borrowing. The economic implications extend beyond government balance sheets. High debt servicing costs reduce the funds available for infrastructure, healthcare and education. Governments may also need to increase revenue collection, reduce expenditure or borrow more to meet existing obligations. Where borrowing costs remain high, businesses can face tighter access to credit, potentially slowing private investment and employment creation.
Public debt is therefore more than a fiscal statistic. It influences sovereign creditworthiness, Eurobond yields and the cost at which governments access financing. Countries that demonstrate credible fiscal management, transparent reporting and productive use of borrowed funds are better positioned to strengthen investor confidence. The key issue is not simply how much a country owes, but whether its economy and public revenues can support those obligations without undermining future growth. Sustainable debt management requires governments to balance present financing needs with the productive investment needed to expand tomorrow’s economy.
