Developing Countries’ External Debt Hits Record $9.4 trillion – What It Means for Africa

The World Bank has raised the alarm as developing countries external debt climbed 5.5% to a record $9.4 trillion in 2025, a surge driven largely by private‑creditor borrowing and renewed access to international bond markets. For Nigeria and its African neighbours, the warning signals a critical juncture: debt sustainability must be balanced against the need for infrastructure, health and education spending that fuels growth.

Why the developing countries external debt spike matters for African economies

Across the continent, governments have leaned on external financing to bridge fiscal gaps widened by post‑pandemic recovery, climate‑related shocks and geopolitical tensions. While debt can fund vital projects, the rapid rise in developing countries external debt raises red flags about repayment capacity, especially where revenue mobilisation remains weak.

In Nigeria, external debt stood at roughly $115 billion at the end of 2025, accounting for about 30% of total public debt. Ghana, South Africa and Kenya face similar pressures, with debt‑to‑GDP ratios hovering near or above the 60% threshold that the International Monetary Fund (IMF) flags as a warning sign. The World Bank’s latest data underscores that the debt surge is not confined to a few outliers; it is a continent‑wide phenomenon.

Key drivers behind the $9.4 trillion figure

Three inter‑linked forces explain the record level of developing countries external debt:

• Private creditor appetite: Institutional investors, hedge funds and sovereign wealth funds have returned to emerging‑market bonds, attracted by higher yields as global interest rates stabilised after the 2022‑2024 tightening cycle.
• Infrastructure push: Governments are financing large‑scale projects – from renewable energy farms in Kenya to railway upgrades in Ethiopia – often through external loans that carry lower interest than domestic borrowing.
• Currency volatility: Depreciation of local currencies against the dollar has inflated the dollar‑denominated debt burden, making repayment more costly in local terms.

These dynamics are compounded by the lingering effects of the COVID‑19 pandemic, which left many African fiscal balances in the red, prompting a reliance on external sources to fund stimulus and health programmes.

Implications for Nigeria’s fiscal roadmap

For Nigeria, the World Bank’s warning dovetails with ongoing debates about fiscal consolidation, revenue reform and debt management. The country’s 2026 budget aims to broaden the tax base, improve oil‑sector transparency and accelerate digitalisation of tax collection. Yet, external borrowing remains a double‑edged sword.

On the positive side, recent Eurobond issuances have secured lower coupon rates, enabling the government to fund the National Integrated Infrastructure Master Plan without over‑relying on domestic borrowing. On the downside, the debt service bill is projected to climb to over 15% of fiscal revenue by 2028, squeezing space for social spending.

Policy makers therefore face a delicate balancing act: harness external finance for growth‑enhancing projects while keeping debt service within manageable limits.

Regional snapshots: Ghana, South Africa, Kenya and beyond

Ghana’s external debt reached $71 billion in 2025, prompting a restructuring agreement with private creditors in early 2026. The deal, which extended maturities and reduced interest rates, offers a template for other indebted nations but also highlights the importance of transparent negotiations.

South Africa, with its sophisticated bond market, saw external debt rise to $115 billion, driven by a mix of sovereign bonds and corporate borrowing. The country’s fiscal consolidation plan focuses on curbing public‑sector wage growth and improving tax compliance, aiming to keep debt‑to‑GDP below 70%.

Kenya’s external debt, now at $48 billion, reflects heavy borrowing for the Standard Gauge Railway and energy projects. The Kenyan government is exploring blended finance models that combine concessional loans with private‑sector equity to lower the overall cost of capital.

Other economies – Egypt, Morocco, Tanzania and Ethiopia – are also navigating the fine line between leveraging external funds for development and avoiding debt distress. The World Bank’s alarm serves as a reminder that debt sustainability frameworks must be robust, data‑driven and adaptable to shifting global conditions.

What the World Bank recommends

In its 2026 report, the World Bank outlines three priority actions for developing nations:

1. Strengthen debt‑management institutions: Establish independent debt‑management offices with clear mandates, transparent reporting and regular stress‑testing against adverse scenarios.
2. Prioritise concessional financing: Seek lower‑cost loans from multilateral development banks and climate funds for projects that generate public goods, reducing reliance on market‑based borrowing.
3. Enhance revenue mobilisation: Implement digital tax administration, broaden the VAT base and improve customs efficiency to boost domestic resources that can offset external borrowing.

These recommendations echo ongoing reforms in Nigeria, where the Federal Inland Revenue Service (FIRS) has introduced an e‑tax platform that increased collections by 12% in the first half of 2026.

How businesses and investors can respond

Private sector actors should monitor sovereign debt trends as they affect currency stability, interest‑rate outlooks and overall economic confidence. Companies with exposure to foreign‑currency debt can hedge against exchange‑rate risk, while exporters may benefit from a weaker naira that improves competitiveness.

Investors, particularly those in African sovereign bonds, need to assess credit‑risk metrics in light of the World Bank’s warning. Diversifying portfolios across countries with stronger fiscal buffers – such as Botswana and Mauritius – can mitigate concentration risk.

At the same time, the surge in external debt creates opportunities for local financial institutions to develop new products, such as debt‑restructuring advisory services and green‑bond issuance platforms, aligning with the continent’s push for sustainable finance.

Looking ahead: 2027 and beyond

As the world moves into 2027, the trajectory of developing countries external debt will hinge on several variables: global interest‑rate trends, commodity price stability and the pace of climate‑related investments. African governments that embed debt‑sustainability into their development strategies are likely to maintain investor confidence and avoid the pitfalls of debt distress.

For Nigeria, the next fiscal year will be a test of how well the country can balance growth‑oriented borrowing with prudent fiscal discipline. Success will depend on effective implementation of revenue reforms, disciplined project selection and transparent debt‑management practices.
