Africa's Debt Dilemma: Why Borrowing Fails to Fuel Growth

The Paradox of Africa’s Debt Crisis

Africa is facing a growing debt crisis that highlights a troubling contradiction: the continent is rich in natural resources yet burdened by increasing liabilities, infrastructure gaps, persistent poverty, and weak institutions. Countries like Ghana and Nigeria exemplify this trend, with Nigeria’s liabilities consuming 75% of its revenue and external borrowing reaching $24.14 billion. This pattern of borrowing without transformation is evident across many African nations.

In contrast, Rwanda has demonstrated a more strategic approach to debt, drawing inspiration from Asian success stories such as South Korea, Singapore, and China. These countries have shown that disciplined investment can turn liabilities into engines of growth. Rwanda's debt-to-GDP ratio increased from 20% in 2010 to over 80% in 2025, which led to a Fitch downgrade. However, the country has used its borrowings to invest in infrastructure, health, and technology, supported by long-term planning and relatively strong governance.

The contrast between African giants and Rwanda, as well as Asian countries, is stark. While many African nations struggle with rising debt and limited returns, Rwanda and Asia demonstrate that under the right conditions, debt can drive sustainable growth. The central question for Africa is no longer whether to borrow, but why decades of borrowing have failed to deliver sustained prosperity and what lessons can be drawn to rewrite the continent's debt path in line with productivity.

Public Debt vs Growth Productivity: Africa vs Asia

The "Debt Productivity Index" (DPI), an analytical tool that uses debt-to-GDP and GDP per capita growth, captures the relationship between debt and productivity. Nigeria's debt-to-GDP ratio rose from 39.1% in 1989 to 56.6% in 1990, then declined to 39.4% in Q1 2025 after GDP rebasing. Despite this, Nigeria's DPI has steadily declined, similar to Ghana's trajectory, even though Ghana's debt-to-GDP peaked above 80% in the mid-2010s and again in 2023-2024.

Rwanda's debt-to-GDP ratio increased from 20% in 2010 to over 80% in 2025, yet its DPI shows a corresponding positive increase. This mirrors patterns seen in South Korea, Singapore, and China. For example, South Korea's debt-to-GDP is forecast to reach 53.6% by 2028, China's to 110% by 2029, and Singapore's to 175% in 2025. These examples show that rising debt, when tied to productivity, can lead to transformative outcomes.

Africa's Debt Landscape

Over the past 15 years, Africa's debt has surged significantly. The Sub-Saharan Africa median debt-to-GDP ratio reached 60% in 2025, doubling the 30% recorded in 2010. Nigeria's 2025 ratio of 45% is below the continental average, while Ghana's exceeds 80%. Sudan remains in chronic debt distress, unable to regain international creditworthiness.

Africa's debt structure is increasingly reliant on external borrowing through Eurobonds and bilateral loans from China. Domestic debt markets remain underdeveloped, constrained by weak savings and fragile financial systems. Global shocks, commodity price volatility, and interest rate hikes have pushed many African countries into unsustainable debt service positions.

The Debt Paradox in Africa: Rwanda as an Outlier

Africa's paradox is multifaceted: resource-rich yet fiscally distressed, attracting financial inflows but suffering from debt overhang. The continent faces power shortages, food insecurity, and illicit financial flows exceeding $89 billion annually. Debt servicing diverts funds from health, education, and infrastructure, undermining human capital and deterring investment.

Rwanda stands out as an exception. Its long-term plans, such as Vision 2050, focus on productivity-enhancing investments in transport, ICT, and health. Stronger governance and alignment with donors and multilaterals rationalize its debt-to-GDP climb to over 80% in 2025. While not risk-free, Rwanda's debt strategy shows that high debt can support transformation if well managed.

Africa vs Asia: What Went Wrong?

Asian economies once faced similar savings gaps. South Korea's economic miracle was driven by heavy borrowing tied to industrial policy, mass education, and export-oriented manufacturing. Singapore's borrowing between 1970 and 1990 funded world-class infrastructure and human capital. China's 1978 reforms leveraged debt to finance infrastructure and technology, lifting over 800 million people out of poverty. The common thread: long-term planning, institutional discipline, and strategic use of debt for development.

In contrast, African borrowing has often been reactive, fragmented, consumption-driven, and applied to politically motivated projects rather than productivity multipliers. Weak institutions and corruption crowd out fiscal space, trapping governments in cycles of refinancing without growth.

Lessons for Nigeria and Africa

To escape perpetual fiscal fragility, Africa must go beyond debt restructuring. Key reforms include:

• Fiscal discipline and transparency: Align debt with credible development strategies and national priorities.
• Domestic revenue mobilisation: Tax reforms must reduce dependence on borrowing. In Nigeria, scepticism around the 2025 tax reforms fuels non-compliance, highlighting the need for public trust. Trust in governance is critical to long-term fiscal sustainability.
• Growth-enhancing investment: Debt must fund projects tied to measurable growth multipliers and long-term planning.
• Institutional strengthening: Democratic institutions must be fortified to eliminate inefficiencies and inconsistent borrowing.
• Governance and accountability: Prevent misuse of debt and ensure high returns on public investment.
• Strategic deployment: Debt must be a deliberate development tool—not a reactive deficit plug.

Unproductive debt must not define Africa's destiny. Rwanda, South Korea, Singapore, and China show that debt, when anchored in discipline, vision, and strong institutions, can fuel transformation. For Nigeria and its peers, the debt paradox is not just fiscal, it is systemic. The task is clear: close governance and strategy gaps, turn liabilities into productivity, inclusive growth, and lasting prosperity.
