A Continental Snapshot of Rising Liabilities
The Lomé conference convened by the African Union last May offered a rare, uncluttered view of the continent’s fiscal pulse. Delegates heard the Executive Secretary of the United Nations Economic Commission for Africa, Clever Gatete, confirm that Africa’s external debt stock has climbed to an estimated US$1.86 trillion in 2024, almost doubling in less than a decade. The average debt-to-GDP ratio has risen from 44.4 percent in 2015 to 66.7 percent today, intensifying discussions on solvency, liquidity and growth-friendly refinancing.
United Creditors Shaping the Landscape
Multilateral institutions remain pivotal. The World Bank, the International Monetary Fund and the African Development Bank, alongside bilateral partners such as China, are still the largest official lenders, while private investors on international capital markets increasingly influence borrowing costs. This creditor mix complicates restructuring talks, obliging finance ministries to negotiate simultaneously with development banks that prioritise concessional terms and bondholders driven by mark-to-market calculations.
Decoding the Debt-to-GDP Red Zone
Current IMF data place Sudan at the apex with a debt burden of roughly 253 percent of GDP, a by-product of protracted conflict and limited export capacity. Senegal follows at 119 percent, its infrastructure push outpacing fiscal revenues. Zambia, having already sought relief under the Common Framework, stands at 114 percent. The insular economy of Cabo Verde still carries 109 percent despite recent consolidation. The Republic of Congo appears in the intermediate bracket at 93.6 percent, just ahead of Mozambique, whose liabilities surpass annual output. Egypt’s ratio, around 83 percent, masks a daunting cash interest bill of more than US$21 billion in the first half of the 2024-2025 fiscal year. Malawi and Mauritius are tied close to 88 percent, while Guinea-Bissau closes the list at 82 percent, its domestic debt representing over half of total obligations.
Republic of Congo: Balancing Risks and Reforms
Brazzaville’s debt has climbed chiefly on the back of domestic issuances intended to smooth expenditure in the wake of oil-price volatility. At 93.6 percent of GDP, the ratio remains below the triple-digit threshold that often triggers restructuring alarms, yet refinancing pressures have undeniably intensified. The government has responded with a multi-pronged strategy: enhancing revenue mobilisation through digital customs management, deepening cooperation with the IMF on expenditure rationalisation and pursuing a transparency agenda that publishes quarterly data on public liabilities. Officials close to the finance ministry underline that these measures are designed “to build market confidence while safeguarding social programmes”, a line echoed by independent economists who nevertheless caution that execution speed will be decisive.
Experts Urge Coordinated Relief and Investment
A panel of 25 independent specialists, chaired by former South African finance minister Trevor Manuel under the G20’s auspices, argues that the figures above are only the overture to a deeper challenge. “Africa is not facing a debt crisis alone; it is facing a development crisis,” Clever Gatete told participants in Lomé, warning that growing interest payments are crowding out health, education and critical infrastructure. The panel’s communiqué advocates a synchronised approach that would align concessional refinancing with new capital flows into green energy, digital connectivity and agro-processing—sectors that could expand tax bases and ease future repayment obligations.
Beyond Numbers: Debt as a Development Question
The debate is increasingly framed less around immediate solvency than around long-term transformation. Countries in the upper half of the debt table share common traits: heavy exposure to external shocks, narrow export baskets and limited domestic savings. Addressing these structural constraints, analysts contend, will require patient capital and policy predictability rather than mere austerity. For the Republic of Congo, this means leveraging hydrocarbon revenues to accelerate diversification into timber, telecommunications and agri-industries, while refining debt management offices that can weigh concessional versus commercial borrowing in real time.
In the end, Africa’s US$1.86 trillion liability mountain cannot be viewed in isolation. It is entwined with the continent’s demographic dynamism, its urgent climate adaptation needs and the quest for inclusive growth. The top-ten ranking serves as an alarm bell, but also as an invitation to design cooperative solutions where creditors, debtors and private investors share an interest in prosperity grounded in sustainability.
