Nigeria’s public debt has exceeded N159.3 trillion ($111 billion), driven by naira depreciation, the formalisation of central bank Ways and Means overdrafts, and new borrowing including the $516 million (N707 billion) loan approved by the House of Representatives on April 28, 2026, for the Lagos-Sokoto Superhighway. Federal revenue remains constrained at N10 trillion to N15 trillion annually, while debt servicing has consumed over 100% of revenue in some periods, limiting space for development spending. For insights into economic pressures, see Nigeria's $500M Research Fund.

In 2024, debt servicing exceeded federally retained revenue, with estimates from the Nigerian Economic Summit Group placing the ratio above 110%. This left no revenue for capital or social services, forcing all such spending to come from borrowing.

According to the Debt Management Office (DMO), total public debt reached N159.28 trillion ($111 billion) by December 31, 2025, up roughly N70 trillion nominally from mid-2023. In dollar terms, external debt has remained stable between $105 billion and $113 billion. The naira increase largely reflects depreciation: a $10 billion external debt was N4.6 trillion at N460/$ in early 2023 but over N15 trillion at N1,500/$ in 2025.

Per capita debt is approximately N724,000 based on a 220 million population.

Revenue vs Debt Service

Federally retained revenue was N10-11 trillion in 2023 (debt service N8-9 trillion, ratio 80-90%) and N12-13 trillion in 2024 (debt service N13-14 trillion, ratio ~100-110%). In January-July 2025, revenue was N13.67 trillion (42.7% below pro-rata target), while debt service (N9.81 trillion) and personnel costs (N4.51 trillion) totaled N14.32 trillion, 105% of revenue. Nigeria’s revenue-to-GDP and tax-to-GDP ratios remain below 10%, versus 15-25% in peer economies. Related fiscal enforcement issues are covered in Court Warns FCCPC Boss.

The Ways and Means

Ways and Means advances grew from N790 billion in 2015 to N26.95 trillion by 2023, exceeding the 5% of prior-year revenue cap under CBN Act Section 38. In 2023, N22.7 trillion was securitised into 40-year 9% bonds (with 3-year principal moratorium), followed by N7.3 trillion, totaling nearly N30 trillion. This reduced costs from MPR+3% (~20-21%) and now comprises about one-fifth of total debt, maturing to 2063.

Borrowing Pace and Structure

Since May 2023, external financing totals $18-20 billion: $3 billion Afreximbank crude-backed (2023), $2.2 billion Eurobonds (December 2024), $2.35 billion Eurobonds (November 2025, $13 billion order book), $9 billion World Bank (including $2.25 billion stabilisation credit, June 2024), $1 billion AfDB, and $516.3 million Deutsche Bank for Sokoto-Badagry highway (April 2026). External service costs hit $3.58 billion in first nine months of 2024 (+40% YoY). Domestic debt exceeds N70 trillion at 18-24% rates. Infrastructure challenges persist, as in Tegbe Confirmed: 100-Day Pledge.

Borrowings serve project-tied needs (e.g., highways, ports), budget support for deficits (N23.85 trillion projected 2026), and refinancing. Non-discretionary spending (debt service, recurrent) is 60-70% of budgets; 2026 halts new capital projects, rolling over 70% of 2025 allocations.

Debt Servicing in 2026 Budget

The 2026 budget totals N68.32 trillion, with debt service at N15.8 trillion, more than combined defence/security (N5.4 trillion), infrastructure (N3.6 trillion), education (N3.5 trillion), and health (N2.5 trillion) at ~N15 trillion. Debt service is 23-27% of expenditure and 50-60% of revenue, up from under N4 trillion in 2022. Health sectors face cuts, echoing concerns in Dean’s Alarm: 0.5% Oral Health Budget.

2026 Budget Key Allocations (Trillions Naira)
Sector	Allocation
Debt Service	15.8
Defence/Security	5.4
Infrastructure	3.6
Education	3.5
Health	2.5

Interest vs Principal

Debt service is interest-heavy: Eurobonds 83% interest ($2.43 billion of $2.93 billion, Q3 2023-Q2 2025); domestic 95.7% interest (N8.24 trillion vs N0.37 trillion principal in 2025). New borrowing often refinances maturing debt.

Multilaterals hold 49.4% of external debt: World Bank/IDA $18-20.2 billion, AfDB $3.3 billion, IMF $2 billion. Eurobonds $18.5 billion; China $4.91-5.6 billion; others (France, Japan, India, Germany).

Government’s Argument vs Critics

The administration attributes debt growth to naira valuation effects, Ways and Means formalisation, and reforms (subsidy removal, FX unification) enabling 3.87% GDP growth and market access (oversubscribed Eurobonds). Critics highlight debt service >100% of revenue as the key risk (vs debt-to-GDP ~52.7%), borrowing for recurrent needs over productive investments, and weak National Assembly oversight.
