Nigeria External Debt Rises 6.6% to $145.02bn in 2025

Nigeria's total external debt stock stands at $145.02 billion at the end of 2025, a 6.6 per cent rise from $135.99 billion a year earlier and a 74.3 per cent jump from $83.21 billion in 2015, the World Bank's International Debt Report 2026 shows — a headline that understates how far the structure of the country's foreign borrowing has shifted toward costlier, more private funding.

The report, released this week and now circulating through Abuja's policy community, is unusually candid about the denominator problem: debt to exports has stretched to 212 per cent and debt service consumes 19 per cent of export earnings and 5 per cent of gross national income, both measured service ratios rising 9.6 percentage points and 6.9 percentage points respectively. Nigeria's external obligations, in short, have grown more slowly than the income those obligations must service has shrunk or merely failed to accelerate.

The private share nobody was counting on

The composition of the $145 billion is the real news. The World Bank breaks the total into public and publicly guaranteed debt of $62.4 billion, private non-guaranteed debt of $54.48 billion and short-term obligations of $28.14 billion — meaning private-sector borrowing (corporate plus non-guaranteed) accounts for more than half of Nigeria's externally noted debt. This is the shape financing has taken in an economy where the government has been pushing projects through Development Finance and corporate channels rather than straight sovereign borrowing.

Within the public external debt, multilateral creditors hold $31.365 billion — with the World Bank's IDA window at $18.533 billion and the IMF's SDR-related exposure at $5.516 billion — bilateral creditors hold $6.683 billion (China leading at $5.672 billion, France at $774 million), and private creditors hold $24.352 billion. The Debt Management Office's own publication puts World Bank Group exposure at $20.73 billion and Eurobonds at $18.55 billion, with external debt service running at $1.82 billion in the first half of 2026.

The cost contours of the two books

The report details what is effectively the toll for the bifurcated funding model. Nigeria's new official borrowing in 2025 carried a 25-year maturity, a five-year grace period and a 1.9 per cent interest rate — the classic concessional package. Its private-sector borrowing, by contrast, feature averages a 12-year maturity, an eight-year grace and 9.6 per cent interest — five times the coupon, wrapped around debts that cannot be rationed the way concessional window allocations are.

The sovereign itself went to market on those terms. Nigeria raised a $2.3 billion dual-tranche Eurobond in 2025, with ten-year paper at 8.625 per cent and 20-year paper at 9.125 per cent, and in 2026 entered a $5 billion Total Return Swap — a three-year structure roughly 133 per cent collateralised with about $6.7 billion of domestic securities placed with the counterparty. That swap is the clearest marker yet of the strategy rather than the exception: the sovereign is now monetising domestic assets against foreign-currency liabilities, borrowing implicitly at a derivative-adjusted cost in order to avoid printing a Eurobond.

The global driver behind the totals

The Nigerian figures arrive in a wider global picture the report frames in uncomfortably simple terms: external debt for low- and middle-income countries hit a record $9.4 trillion in 2025, a 5.5 per cent rise — the largest annual increase in four years — while the group's global debt-service payments reached $1.4 trillion. Whatever Nigeria's share of that total, the direction of travel is set by commodities, capital markets and the cost of USD funding, not by domestic policy alone.

For the wider region, Nigeria remains the third-largest issuer of external debt in sub-Saharan Africa, so its increase pushes both the regional average and the pressure on the discount rate applied to African sovereign risk. Punch notes that the DMO's public external debt figure for June 30, 2026 is $54.52 billion — meaning the World Bank's public-and-guaranteed number has been rising even as the DMO's focus-of-attention figures have barely moved above half that level, a gap suggesting not the debt that lives on non-guaranteed private balance sheets is no longer trackable by conventional instruments.

What the debt numbers should check around policy

Fiscal analysts read this mixture for quarter-by-quarter stress rather than a solvency crisis. Nigeria's foreign-exchange earnings environment has improved through stronger non-oil flows, and the megaphone story of the 2025 deterioration was Eurobond pricing, not default risk — the country retained market access even while headlines included rate-cut talk of a 23 per cent policy rate cut. But that is precisely why the maturity and coupon differentials matter: a 9.6 per cent private book does not benefit from global cutting cycles in the way a concessional book does, and its nominal dollar service will now drain FX from the external account every quarter regardless of the global backdrop.

The Nigeria-specific lesson is difficult and uncomfortable: the debt load can continue to rise in this denominator (through the private book, corporate funding and short-term flows) without a single new dollar of conventional borrowing being signed. That means the headline sovereign-sustainability conversation is now incomplete — Nigeria's foreign-currency exposure risk is also increasingly engrained in private energy, telecoms, manufacturing and commodity companies whose performance the government can no longer directly manage but whose failures it cannot politically afford to ignore.

For investors, the report's key ledger is the exchange rate. Private external debt in a fearful market-friendly environment becomes a currency dilemma: if naira stability is preserved through the external account strengthening, non-guaranteed corporate debt services without fiscal stress; if it does not, the private book amplifies the very FX pressure the public monetary response is trying to absorb. Nigeria's 2026 borrowing — the swap, the private book, the short-term stacking — is being made in a window where naira deliverability and debt durability are judged together.
