Nigeria paid an average interest rate of 9.6 per cent on new external loans from private creditors in 2025, over five times the 1.9 per cent charged by official lenders. The World Bank published these figures in its International Debt Report 2026, exposing the steep premium Abuja and local firms pay when tapping global commercial markets. Expensive private debt now eats into national earnings as total external obligations hit $145.02 billion.
Commercial lenders also impose far harsher repayment timelines than multilateral institutions and foreign governments. Private creditors demanded full repayment within an average of 12 years, whereas official lenders granted 25-year maturities to ease fiscal pressure. Short tenors force Nigerian borrowers back into volatile capital markets far too often to refinance maturing obligations.
Desperation for quick foreign exchange pushes policymakers toward costly bond markets despite the long-term fiscal damage. In 2025 alone, Nigeria returned to international capital markets as Sub-Saharan Africa’s third-largest issuer, raising $2.3 billion through dual-tranche Eurobonds priced at 8.625 per cent and 9.125 per cent. Cheap multilateral money comes with strict policy conditions, so governments often buy speed at a punishing price.
Private sector borrowing has quietly become the fastest-growing component of Nigeria’s foreign debt burden. Unbacked corporate external liabilities surged by 179.6 per cent over seven years to reach $54.48 billion, nearly matching the state’s $62.4 billion public external debt. When local companies earn naira yet owe dollars at commercial rates, any currency slide threatens corporate solvency.
Debt service already swallows 19 per cent of Nigeria’s export earnings and five per cent of Gross National Income. Data from the Debt Management Office shows the federal government spent $1.82 billion servicing external debt in the first half of 2026, with interest payments alone consuming 61 per cent of that outlay. Every dollar wired to foreign bondholders leaves fewer funds for power grids, schools, and clinics at home.
High borrowing costs reflect deep investor scepticism over Nigeria’s economic reforms and revenue collection. Multilateral development banks offer a cheap lifeline, yet Abuja cannot build an entire economy on concessional charity forever. Until policymakers boost non-oil exports and tame inflation, global markets will keep charging Nigeria a steep risk tax.
