Nigeria’s total public debt rose toN159.28 trillion as at 31 December 2025, according to the Debt Management Office (DMO), representing a 3.9 percent quarter-on-quarter increase from N153.29 trillion in September 2025 and a 10.1 percent year-on-year rise from N144.67 trillion in December 2024.
DECISION HIGHLIGHT
The latest debt figures indicate that fiscal consolidation efforts remain insufficient to offset Nigeria’s structural financing gap, with continued borrowing reinforcing dependence on debt-funded budget execution despite revenue-enhancement measures.
DECISION MEMO
Nigeria’s rising debt stock underscores that the fiscal authorities have not yet transitioned from deficit management to deficit reduction. While debt growth has moderated relative to prior high-expansion periods, the continued quarterly increase confirms that expenditure obligations remain materially above sustainable revenue generation.
The composition of the debt stock remains instructive. Domestic debt continues to dominate, suggesting the federal government is relying principally on local markets to fund fiscal shortfalls. This may reduce foreign exchange exposure at the margin, but it sustains crowding-out pressure in domestic credit markets and preserves elevated sovereign benchmark yields.
External debt growth remains notable despite exchange rate normalisation assumptions embedded in the DMO’s methodology. Because the debt stock is partly exchange-rate sensitive, naira appreciation versus the prior quarter moderated the reported local currency value of foreign obligations. Absent that valuation effect, the debt increase would likely appear steeper.
The broader implication is that Nigeria’s debt challenge remains less about absolute stock than debt affordability. Rising obligations would be less concerning if matched by stronger revenue mobilisation, lower debt-service ratios, or materially productive capital deployment. Current trends suggest those offsets remain inadequate.

WHO WINS / WHO LOSES
Winners are domestic fixed-income investors and banks benefiting from sustained sovereign issuance and elevated yields.
Losers include private sector borrowers facing continued crowding-out, taxpayers exposed to future fiscal tightening, and subnational governments competing for shrinking financing headroom.
POLICY SIGNALS
The figures indicate that fiscal authorities are likely to maintain aggressive revenue mobilisation, tax reform, and expenditure-rationalisation efforts.
They also increase pressure for stronger debt management discipline and tighter scrutiny of new borrowing approvals.
INVESTOR SIGNAL
Investors should interpret the debt increase as evidence that Nigeria remains in a high-borrowing, high-yield sovereign environment.
Fixed-income markets may remain attractive in nominal terms, but medium-term macro confidence will depend increasingly on whether debt growth begins to decelerate relative to revenue growth.
RISK RADAR
Key risks include further debt-service escalation, continued domestic market crowding-out, exchange-rate shocks inflating external debt obligations, and weakening investor confidence if borrowing continues to outpace fiscal reform.
The central concern is not debt accumulation alone, but the absence of sufficiently visible fiscal compression to alter the trajectory materially.
