Which African Countries Owe the Most to the World Bank’s IDA — and Why It Matters
Across Africa, governments are borrowing at a scale that would have been unimaginable two decades ago — and much of that debt runs through a single institution. The International Development Association, the World Bank’s concessional lending arm, has quietly become one of the continent’s most consequential creditors, financing everything from rural roads in Tanzania to health systems in Nigeria. Understanding who owes what, and why, is essential to reading Africa’s economic future clearly.
What the IDA Actually Is — and How Big It Has Become
The International Development Association was established in 1960 as a mechanism to extend World Bank financing to countries too poor to qualify for standard market-rate loans. Unlike commercial debt, IDA credit comes with highly concessional terms — typically zero or near-zero interest rates, grace periods of five to ten years, and repayment schedules stretching up to 40 years. The institution is backed by 173 shareholder nations, which periodically replenish its funding through negotiated rounds known as IDA replenishments.
As of June 30, 2024, IDA’s total outstanding loan portfolio stood at $198.5 billion — a jump of $10.8 billion from the $187.7 billion recorded just one year earlier. Grant disbursements also accelerated sharply, rising from $3.9 billion in FY2023 to $5.3 billion in FY2024. These figures reflect both growing demand from low-income borrowers and a deliberate push by the World Bank to scale up development financing in the wake of overlapping global crises, including the COVID-19 pandemic, climate shocks, and food insecurity driven by the war in Ukraine.
The Six African Countries with the Largest IDA Debt Burdens
Nigeria leads all African nations with $16.5 billion in outstanding IDA debt as of 2024 — a figure that reflects both the country’s enormous population of over 220 million people and its persistent infrastructure deficit. Ethiopia follows with $12.2 billion, despite years of internal conflict that have complicated project implementation across the country’s regions. Kenya sits close behind at $12.0 billion, with borrowing concentrated in infrastructure, energy, and social protection programs. Tanzania rounds out the top four at $11.7 billion, driven by large-scale investments in transport corridors and rural electrification.
Ghana and Uganda occupy the fifth and sixth positions, with $6.7 billion and $4.8 billion respectively. Ghana’s IDA exposure is particularly significant given the country’s 2023 debt restructuring under the IMF’s Extended Credit Facility — a process that forced Accra to renegotiate obligations with bilateral and commercial creditors while IDA debt, classified as preferred creditor status, remained protected from haircuts. Uganda’s borrowing has focused heavily on education, water sanitation, and road connectivity in its landlocked interior. Together, these six countries account for the vast majority of Africa’s total IDA exposure.
Why African Governments Keep Turning to the IDA
The logic of IDA borrowing is straightforward: no private lender offers 40-year repayment windows at zero interest for a road project in rural Kenya or a maternal health clinic in northern Nigeria. For governments operating with thin tax bases and competing fiscal pressures, IDA credit is often the only viable financing instrument for long-horizon development investments. The World Bank also bundles loans with technical assistance, policy advice, and institutional capacity support — making it a more comprehensive partner than a simple creditor.
But the scale of borrowing also reflects structural weaknesses. Countries like Ethiopia and Tanzania have limited domestic capital markets, making external concessional debt a near-necessity for public investment. Nigeria, despite being Africa’s largest economy by GDP, carries a chronically low tax-to-GDP ratio — hovering around 10 percent, well below the African average — which constrains its ability to self-finance infrastructure. The IDA fills a gap that domestic resource mobilization has failed to close, a dynamic that shows no sign of reversing in the near term.
The Debt Sustainability Question No One Wants to Answer
IDA debt is often described as “safe” because of its concessional terms and the institution’s preferred creditor status — meaning it is shielded from restructuring even when a country defaults on other obligations. That protection, however, does not make the debt costless. Repayment obligations still consume fiscal space. Ethiopia, currently navigating a debt restructuring under the G20 Common Framework, carries $12.2 billion in IDA obligations that sit outside the restructuring perimeter — a reality that shapes how much relief Addis Ababa can realistically extract from the process.
The World Bank itself has acknowledged the tension. In recent years, it has introduced “debt sustainability filters” into IDA lending decisions, designed to prevent new borrowing from pushing countries beyond manageable thresholds. Whether those filters are calibrated correctly — and whether borrowing governments have the institutional capacity to deploy funds productively — remains one of the central debates in African development finance.
A Creditor Relationship That Will Define the Next Decade
The IDA’s growing footprint in Africa is neither inherently good nor bad — it is a mirror of the continent’s development financing reality. With $198.5 billion in global outstanding loans and six African nations each carrying more than $4 billion in obligations, the relationship between the World Bank and African governments will shape public budgets, infrastructure timelines, and fiscal policy choices well into the 2030s. The critical question is not whether to borrow, but whether the investments financed by that debt generate enough economic growth to make repayment sustainable — and whether African governments are asking that question rigorously enough before they sign.
