Nigeria's sovereign debt represents one of the most critical structural challenges within its macroeconomic architecture — characterized by low debt-to-GDP but catastrophic debt service-to-revenue ratios.
Domestic (60-65% of total): FGN Bonds (long-term, held by pension funds/banks), Nigerian Treasury Bills (short-term cash management), Ways and Means Securitized Bonds (22.7 trillion NGN, 40-year at 9%), Sukuk and Green Bonds for infrastructure.
External (35-40%): Multilateral (World Bank IDA/IBRD, AfDB — cheapest, longest-term), Bilateral (China ExIm Bank — railways, airports, telecom), Commercial Eurobonds (6.5-10.5% coupons, dollar-denominated, sovereign FX risk).
Debt-to-GDP ratio remains moderate (below 45%) but debt service-to-revenue has exceeded 80-95% in recent fiscal years, leaving near-zero fiscal space for capital expenditure. The state borrows just to pay salaries and service interest.
When naira devalued from ~460 NGN/USD to 1,500+ NGN/USD, the naira-denominated value of external debt tripled overnight. No corresponding increase in real output or tax revenues.
Domestic crowding out: double-digit sovereign yields make bank lending to real-sector enterprises economically irrational. Eurobond refinancing in high-rate global environment. Securitization drag: 22.7 trillion NGN amortized over 40 years represents a continuous fiscal drain for decades.
