NIGERIA PAID FIVE TIMES MORE FOR PRIVATE FOREIGN LOANS AS EXTERNAL DEBT HIT $145BN

ABUJA, NIGERIA Nigeria paid dramatically higher interest rates when borrowing from private international creditors than when obtaining new financing from official lenders in 2025, highlighting the growing cost of relying on commercial markets as the country’s total external debt stock climbed to about $145.02 billion. New commitments from private creditors carried an average interest rate of 9.6 percent, more than five times the 1.9 percent average charged on new loans from official creditors, according to the World Bank Group’s latest International Debt Statistics. The figures underline a central challenge facing Africa’s largest economy: while Nigeria retains access to concessional and relatively low-cost financing from multilateral and bilateral institutions, borrowing from private markets can impose substantially heavier interest costs that ultimately compete with government spending on infrastructure, health, education and other public priorities.

The World Bank data show that the difference extended beyond interest rates. New loans from official creditors in 2025 had an average maturity of 25 years and a five-year grace period, giving Nigeria considerably more time to repay principal and spread financing costs over a longer horizon. Private-creditor commitments, by comparison, had an average maturity of 12 years, an eight-year grace period and an interest rate of 9.6 percent. Although the longer grace period on the private loans delayed principal repayments, the significantly higher coupon and much shorter overall maturity meant that commercial financing remained considerably more expensive and created greater refinancing pressure over time.

Nigeria’s total external debt stock reached $145.015 billion at the end of 2025, according to the World Bank database, up 6.6 percent from $135.988 billion in 2024. The increase extended a decade-long rise from $83.213 billion in 2015, meaning the country’s external obligations grew by roughly $61.8 billion over 10 years. The World Bank figure is broader than the external public debt numbers regularly published by Nigeria’s Debt Management Office because it includes not only government and publicly guaranteed obligations but also private nonguaranteed external borrowing, short-term foreign debt and other categories captured under the World Bank’s external debt methodology.

That distinction is important because the $145.02 billion figure should not be interpreted as debt owed entirely by the Federal Government of Nigeria. The World Bank classified $62.4 billion of Nigeria’s 2025 external debt as public and publicly guaranteed, while private nonguaranteed debt accounted for about $54.48 billion and short-term external debt stood at approximately $28.14 billion. Nigeria’s Debt Management Office, using its narrower public-debt framework, reported total public external debt of $51.86 billion at the end of December 2025. The two figures therefore measure different things and are not contradictory: the DMO number covers government and qualifying public-sector obligations, while the World Bank’s total external debt stock captures a much wider range of liabilities owed abroad by the Nigerian economy.

Within the $62.4 billion in public and publicly guaranteed external debt identified by the World Bank, multilateral institutions remained the largest creditor group, accounting for approximately $31.37 billion. Private creditors held about $24.35 billion, while bilateral lenders accounted for roughly $6.68 billion. The World Bank’s International Development Association, which provides highly concessional financing to lower-income and eligible lower-middle-income countries, represented $18.53 billion of Nigeria’s multilateral obligations, while International Monetary Fund credit and Special Drawing Rights allocations amounted to about $5.52 billion and other multilateral institutions accounted for roughly $7.32 billion.

China remained by far Nigeria’s largest bilateral creditor in the World Bank data, with approximately $5.67 billion outstanding, followed by France with about $774 million and other bilateral creditors with roughly $237 million. Those bilateral obligations are typically associated with infrastructure, development projects and other government-backed financing arrangements, and their terms can differ considerably depending on the lender and project. The relatively small bilateral share compared with multilateral and private creditors also illustrates how Nigeria’s external financing structure has evolved beyond the public debate that often focuses heavily on Chinese lending.

The most striking new finding, however, is the price Nigeria paid when it turned to commercial creditors for fresh financing. The 9.6 percent average interest rate reflects the premium private investors demand to compensate for sovereign risk, global interest-rate conditions, currency exposure and expectations about Nigeria’s fiscal and economic outlook. Official lenders such as the World Bank, African Development Bank and bilateral development agencies are able to offer substantially cheaper financing because their loans are often designed around development objectives rather than purely commercial returns and can include long maturities and concessional terms unavailable in international bond markets.

Nigeria’s return to global capital markets in 2025 illustrates that contrast. The country raised about $2.3 billion through a dual-tranche international bond transaction, with one 10-year tranche priced at an interest rate of 8.625 percent and a 20-year tranche carrying 9.125 percent. Those rates were lower than the 9.6 percent average across private commitments reported by the World Bank but still dramatically above the terms available from official creditors. For a government borrowing billions of dollars, even a difference of several percentage points can translate into hundreds of millions of dollars in additional interest over the life of a loan.

Commercial borrowing is not inherently problematic and can provide governments with flexibility, speed and access to larger pools of capital than some development institutions can supply. International bonds can also help establish a sovereign yield curve that assists domestic companies seeking foreign financing and allows governments to diversify their creditor base. The concern arises when expensive market borrowing expands faster than revenues, when loans finance spending that does not generate sufficient economic returns or when large maturities cluster within short periods and force governments to refinance at unfavorable rates.

Nigeria’s debt debate has increasingly centered on precisely that issue. The country’s debt-to-GDP ratio remains moderate compared with many emerging and advanced economies, but weak government revenue collection means debt-service payments consume a large share of available income. The International Monetary Fund estimated that Federal Government interest payments absorbed about 53.2 percent of federal revenue in 2025 and projected a similarly elevated burden in 2026. That means Nigeria can appear relatively comfortable when debt is measured against the overall size of the economy while simultaneously facing severe fiscal pressure when repayment costs are compared with the revenue actually reaching government accounts.

The World Bank has made a similar distinction in its assessments of Nigeria’s public finances. Its Nigeria Development Update has repeatedly identified debt service relative to revenue, rather than debt stock relative to GDP alone, as one of the country’s main fiscal vulnerabilities. Revenue reforms, higher oil production, improved tax administration and changes introduced under the current government have strengthened some fiscal indicators, but the country still raises substantially less government revenue as a proportion of GDP than many comparable economies. That structural weakness makes expensive borrowing particularly consequential because every additional interest payment reduces the fiscal space available for services and capital investment.

Nigeria’s broader macroeconomic position has nevertheless improved in several areas since the severe instability that followed the foreign exchange and subsidy reforms introduced from 2023. The naira has become more stable after major depreciation, foreign reserves and the external position have strengthened, oil production has improved and investor confidence has recovered from previous lows. The IMF’s 2026 assessment classified Nigeria’s overall risk of sovereign stress as moderate and cited the country’s relatively low public-debt ratio, long maturity profile and improving macroeconomic conditions as factors supporting the outlook.

The IMF also warned that significant risks remain, including weak domestic revenue mobilization, expenditure overruns, volatile global financial conditions and lower oil prices. Those risks are especially important when considering commercial foreign borrowing because market interest rates can rise rapidly when global investors become more risk-averse. A deterioration in oil prices, the exchange rate or Nigeria’s fiscal outlook could therefore make future Eurobond issuance considerably more expensive even if the country remains able to borrow.

Exchange-rate risk adds another layer to the problem. External debt is generally denominated in dollars, euros, yen or other foreign currencies, while most Nigerian government revenue is collected in naira. When the naira depreciates, the local-currency value of foreign debt and the naira cost of servicing it can rise sharply even if the original dollar amount remains unchanged. The significant devaluation of the naira since 2023 dramatically increased the domestic-currency value of Nigeria’s external public debt, contributing to the rapid expansion of the headline public-debt stock measured in naira.

By the end of 2025, Nigeria’s Debt Management Office reported total public debt of approximately $110.97 billion, equivalent to N159.28 trillion, comprising $51.86 billion in external public debt and $59.12 billion in domestic obligations. The DMO data showed external debt representing 46.73 percent of total public debt, while domestic borrowing accounted for 53.27 percent. The government has maintained that the portfolio remains within its medium-term debt-management limits and has emphasized the importance of balancing domestic and foreign borrowing to reduce excessive dependence on either market.

The public debt stock has continued to rise in 2026. DMO figures for June showed Nigeria’s total public debt reaching approximately $120.93 billion, equivalent to N166.79 trillion. External public debt stood at $54.52 billion while domestic public debt reached $66.41 billion. The Central Bank of Nigeria said the consolidated debt stock remained below national and international debt-to-GDP ceilings, but it also acknowledged that debt service remained a heavy burden on government revenue.

The difference between debt sustainability and debt affordability has consequently become central to Nigeria’s fiscal outlook. A government can technically remain capable of meeting its obligations while still devoting so much revenue to interest and principal payments that spending on development becomes constrained. Nigeria’s challenge has been particularly acute because infrastructure needs are enormous, poverty remains widespread and the government faces pressure to fund security, electricity, healthcare, education and social protection while simultaneously servicing accumulated debt.

Concessional financing from official creditors offers one way to reduce those pressures. Loans from institutions such as the World Bank’s International Development Association can carry low interest rates, long repayment periods and extended grace periods. Those terms significantly reduce annual debt-service requirements compared with commercial bonds. The World Bank’s 2025 figures showing a 1.9 percent average rate and 25-year maturity on new official commitments demonstrate why development finance can be attractive even when public debate focuses primarily on the overall amount borrowed.

Official financing nevertheless comes with limitations. Development loans can involve lengthy negotiations, policy conditions, environmental and social safeguards and restrictions on how funds are used. Funding may also be tied to specific projects or reform programs rather than general budget needs. Private markets, by contrast, can provide large sums relatively quickly and offer governments more discretion over the proceeds, but investors demand compensation for that flexibility through higher yields.

The policy question for Nigeria is therefore not simply whether to borrow but what type of borrowing best matches the purpose for which the money is required. Long-lived infrastructure capable of producing economic returns may justify long-term debt, particularly where financing costs are low and the project increases productivity. Using expensive commercial debt for recurrent expenditure or projects with weak economic returns creates a more difficult fiscal equation because taxpayers must service the borrowing long after the original funds have been spent.

The government has repeatedly said it is seeking to improve debt management while increasing revenue rather than relying primarily on austerity. Tax reforms that began taking effect in 2026 are intended to widen the revenue base and improve compliance, while authorities have also sought to increase oil production and remittances and strengthen customs collections. Higher revenue would reduce the proportion of government income consumed by debt service even if the nominal stock of debt continues to rise.

Nigeria’s debt strategy also increasingly relies on the domestic capital market. Borrowing in naira removes direct exchange-rate risk, but domestic financing is not necessarily cheap. Local interest rates have remained high as the Central Bank tightened monetary policy to combat inflation, and government securities have offered double-digit yields. The DMO’s November 2026 bond calendar includes instruments with coupon rates ranging from about 17.9 percent to 21 percent, illustrating that replacing external commercial debt with domestic borrowing does not automatically lower nominal financing costs.

The comparison between domestic and foreign borrowing therefore involves multiple tradeoffs. Foreign concessional financing can be substantially cheaper but exposes the country to currency movements. Domestic debt avoids foreign-exchange risk but can carry high interest rates and may crowd private borrowers out of local credit markets. Foreign commercial borrowing can extend maturities compared with some domestic instruments and broaden investor access but can become expensive when global yields rise.

The World Bank figures also show why the composition of debt matters as much as the headline total. Nigeria’s $145.02 billion external debt stock includes $54.48 billion owed externally by private entities without government guarantees and $28.14 billion in short-term external debt. Those liabilities affect the economy’s overall foreign-currency exposure but are not equivalent to sovereign debt obligations for which Nigerian taxpayers are automatically responsible. Treating the entire figure as Federal Government debt would therefore overstate the government’s direct external liability.

At the same time, large private external obligations can still create broader economic risks. Banks and companies that borrow abroad must obtain foreign currency to repay their creditors, increasing demand for dollars and potentially placing pressure on reserves and the exchange rate during periods of market stress. If a systemically important company or financial institution struggles to meet foreign obligations, the consequences can spread through the domestic economy even where the government has not formally guaranteed the debt.

The World Bank data placed Nigeria’s external debt at about 212 percent of exports in 2025 and 51 percent of gross national income. External debt service equaled roughly 19 percent of exports and 5 percent of GNI. Those indicators matter because foreign debt ultimately has to be serviced using foreign-exchange earnings, making export performance, oil receipts, remittances and capital inflows central to the country’s capacity to meet external obligations without destabilizing the currency.

Nigeria remains heavily dependent on oil for a large share of foreign-exchange earnings despite attempts to diversify exports. Higher crude production and more stable oil receipts can therefore strengthen debt-servicing capacity, while prolonged declines in prices or production can quickly weaken it. The expansion of domestic refining may reduce demand for imported petroleum products and preserve foreign exchange, but the country still needs stronger non-oil exports if its external financing needs continue to grow.

The government’s ability to secure cheaper official financing will also depend on maintaining relationships with multilateral institutions and meeting the conditions attached to development programs. World Bank loans approved in recent years have supported economic reforms, power-sector investment, education, social protection and other projects. Supporters argue that such financing offers favorable terms unavailable in commercial markets, while critics often question the policy conditions attached to multilateral lending and whether borrowed funds produce measurable improvements.

The latest International Debt Statistics do not by themselves establish that Nigeria is approaching a debt crisis. The IMF continues to classify sovereign stress risk as moderate, and both Nigerian and international assessments point to a public-debt ratio below commonly used ceilings. What the figures do show is that the price at which Nigeria borrows can differ enormously depending on the creditor, with private financing carrying a much heavier interest burden than official lending.

That gap will become increasingly important as the Federal Government weighs future Eurobond issuance, multilateral loans and domestic borrowing against large budget deficits and development needs. Borrowing at 9.6 percent can still make economic sense if funds generate returns greater than their financing cost, but repeated reliance on high-yield debt without corresponding revenue growth can gradually narrow the government’s options and increase refinancing exposure.

The central challenge is therefore not simply the size of Nigeria’s debt but its cost, composition and the quality of spending financed by it. The country has gained greater access to international capital following improvements in macroeconomic stability, but the World Bank data demonstrate that market access carries a price significantly higher than financing offered by official lenders. Maintaining investor confidence may help Nigeria continue raising commercial funds, yet improving revenues and maximizing cheaper long-term financing will be critical if greater market access is to strengthen development rather than deepen future debt-service pressure.

As Nigeria moves through the 2026 fiscal year, the latest DMO figures show that public debt continues to expand even while debt-to-GDP measures remain within official limits. The question facing policymakers is increasingly whether government revenue can grow fast enough to support those obligations and whether new borrowing is being structured on terms that leave sufficient room for development spending. The fivefold interest-rate gap recorded by the World Bank provides a stark measure of that challenge and reinforces the importance of choosing not only how much Nigeria borrows, but from whom, at what price and for what economic purpose.
