Nigeria is paying significantly higher interest rates on new loans from private international creditors than on financing obtained from official lenders, underscoring the rising cost of accessing foreign capital as the country’s external debt stock climbs to $145.02 billion.
Data from the World Bank’s International Debt Report 2026 show that new borrowing commitments from private creditors attracted an average interest rate of 9.6% in 2025, compared with 1.9% for loans from official creditors.
The gap means Nigeria’s average borrowing rate from private lenders was roughly five times the rate charged by official creditors, including multilateral development institutions and foreign governments.
The figures highlight the financial trade-offs facing the Federal Government as it seeks external financing to fund infrastructure, close budget deficits, and manage existing debt obligations.
The World Bank’s country profile for Nigeria shows that official creditors also offered substantially longer repayment periods. New official loans carried an average maturity of 25 years, with a five-year grace period before principal repayments begin.
Private creditors, by comparison, provided loans with an average maturity of 12 years and an eight-year grace period.
Although private financing offered a longer initial grace period, its higher interest rate and shorter overall maturity substantially raise lifetime borrowing costs and create steeper repayment pressure once principal payments fall due.
These terms apply specifically to new borrowing commitments made in 2025 rather than the interest rate across Nigeria’s entire outstanding external debt, where individual loan costs vary by currency, size, maturity, and contractual structure.
The borrowing cost disparity comes against the backdrop of a growing external debt burden. The World Bank put Nigeria’s total external debt stock at $145.02 billion at the end of 2025, representing a 6.6% increase from $136.05 billion in 2024.
Over the past decade, the country’s external obligations have expanded by 74.3%, up from $83.21 billion in 2015.
Public and publicly guaranteed external debt accounted for $62.40 billion of the 2025 total, while private non-guaranteed debt stood at $54.48 billion. Short-term external debt accounted for the remaining $28.14 billion.
This breakdown is critical because Nigeria’s total external debt figure does not reflect sovereign borrowing alone. Private non-guaranteed obligations represent loans contracted by private sector entities without an explicit government guarantee, while short-term debt captures facilities with maturities of one year or less.
Within public and publicly guaranteed debt, multilateral institutions accounted for $31.37 billion (including International Monetary Fund credit and Special Drawing Rights allocations), bilateral creditors held $6.68 billion, and private creditors accounted for $24.35 billion.
The World Bank’s International Development Association, its concessional financing arm for lower-income countries, remained Nigeria’s largest multilateral creditor, with $18.53 billion outstanding. China was the largest bilateral creditor, with $5.67 billion.
Nigeria’s debt-servicing burden also remains elevated. External debt service consumed 19% of export earnings in 2025, while total debt service represented 5% of gross national income, according to the World Bank.
Because external obligations must be settled in foreign currency, committing nearly one-fifth of export receipts to debt service directly constrains the foreign exchange available for domestic liquidity and import financing.
Nigeria’s return to international capital markets further illustrates these borrowing costs. The report noted that the country raised $2.30 billion through a dual-tranche Eurobond issuance in 2025, with the 10-year tranche priced at 8.625% and the 20-year tranche at 9.125%.
Beyond standard bond issuances, the World Bank also flagged growing reliance on complex, non-traditional instruments, such as Nigeria’s $5.00 billion Total Return Swap arrangement in 2026, noting that high collateralization requirements and shorter maturities can heighten refinancing risks during periods of market tightening.
Going into 2027, the Debt Management Office faces a delicate balancing act: leaning more heavily on concessional multilateral windows and domestic borrowing to keep debt-service ratios manageable, while limiting expensive commercial and collateralized facilities that place immediate pressure on foreign reserves.
