Nigeria’s public debt has climbed to a level that is increasingly difficult for ordinary citizens to ignore, with the country’s total public debt portfolio standing at about ₦159.28 trillion as of December 31, 2025, according to the Debt Management Office (DMO).
The figure, which includes the debts of the Federal Government, the 36 states and the Federal Capital Territory, has renewed concerns about how much of the government’s future revenue will be committed to servicing existing obligations and what that means for taxpayers, public services and future generations.
But the headline figure alone does not tell the entire story.
A significant portion of changes in the naira value of Nigeria’s debt stock can be influenced by exchange-rate movements, particularly for foreign-currency obligations. The more important question for citizens and policymakers is therefore not simply how large the debt is, but whether government revenue is growing fast enough to service it without crowding out essential spending.
Nigeria’s public debt consists broadly of domestic and external obligations.
Domestic borrowing includes Federal Government bonds, Treasury Bills and other debt instruments issued within the Nigerian financial market. External obligations include loans from multilateral institutions, bilateral creditors and international capital markets.
The DMO publishes the country’s debt position periodically, with the December 31, 2025 figure being the latest annual total listed in its public debt records.
For citizens, the distinction between domestic and external debt matters because each carries different repayment structures, interest costs and exposure to currency movements.
Foreign-currency debt, for example, becomes more expensive in naira terms when the naira weakens against currencies such as the US dollar.
Nigeria’s government debt is not repaid through a single bill sent to individual citizens.
Instead, the government services its obligations from public revenues, including taxes, oil and gas earnings, customs collections, dividends and other sources of government income.
That creates an indirect connection between national borrowing and everyday life.
When debt-service obligations consume a larger share of government revenue, policymakers have fewer resources available for other priorities unless revenue increases or spending is reduced.
For citizens, that can translate into greater pressure to improve tax collection, reduce subsidies, increase government charges or find other sources of revenue.
A growing debt stock does not automatically mean taxes must immediately rise. Governments can borrow, refinance existing obligations and restructure expenditure.
However, persistent borrowing increases the importance of revenue generation.
Nigeria has been working to expand its tax base and improve collection efficiency, while fiscal authorities have also pursued reforms aimed at reducing government financing pressures.
For households and businesses, the concern is whether efforts to increase government revenue will be accompanied by better public services and a broader economic base.
If tax obligations increase without corresponding improvements in infrastructure, security, healthcare and other public services, the burden becomes more difficult for citizens to absorb.
Economists often pay closer attention to debt service relative to government revenue than to the headline debt figure itself.
A country can carry a large debt stock and remain financially stable if it generates sufficient revenue to meet its obligations. Conversely, even a smaller debt burden can become problematic if government revenue is too weak to cover interest and principal repayments.
This is particularly important for Nigeria because relatively low government revenue compared with the size of the economy has historically constrained the government’s ability to finance public services while meeting debt obligations.
When a large portion of available revenue goes toward debt servicing, fewer resources may remain for roads, schools, hospitals, security and other public investments.
Public borrowing is not necessarily harmful.
Debt can become economically productive when it finances infrastructure and projects capable of expanding economic activity, increasing productivity and generating future revenue.
Borrowing to construct major transport networks, improve electricity supply, expand irrigation or develop industrial infrastructure could strengthen the economy and ultimately increase the government’s ability to repay its obligations.
The problem arises when borrowing is used primarily to finance recurrent expenditure without creating assets or economic activity capable of producing long-term returns.
In such circumstances, future taxpayers can inherit the repayment burden without receiving equivalent economic benefits.
Exchange rates are particularly important when assessing Nigeria’s external debt.
Because part of the country’s debt is denominated in foreign currencies, movements in the naira-dollar exchange rate can significantly affect the naira value of those obligations.
A depreciation of the naira can therefore make the same dollar-denominated debt appear substantially larger when converted into local currency.
This means that changes in the headline naira figure do not necessarily represent the government borrowing an equivalent amount of new money.
It also highlights why stronger foreign-exchange earnings, increased exports and stable currency conditions are important to Nigeria’s long-term debt sustainability.
The consequences of today’s borrowing can extend well beyond the administration that contracted the debt.
Long-term government securities and multilateral loans can remain outstanding for decades. Future governments will therefore inherit the responsibility of servicing obligations accumulated today.
That does not necessarily mean future generations will be worse off.
If borrowed money is invested productively, future Nigerians could inherit better roads, stronger electricity infrastructure, improved healthcare facilities, more efficient transport systems and a larger economy capable of supporting the debt.
But if borrowing grows faster than productive capacity, future taxpayers could face higher taxes and reduced fiscal space while still dealing with infrastructure deficits.
Nigeria’s ₦159.28 trillion public debt figure is therefore more than a number on a government balance sheet.
The central issue is what the country is receiving in return for the money it has borrowed.
If debt finances productive investment, expands the economy and increases government revenue, it can become a tool for development.
If it mainly finances recurring expenses, accumulated deficits or projects that generate little economic value, the burden eventually shifts to taxpayers.
For ordinary Nigerians, the most important question is therefore not simply “Who owes the ₦159 trillion?”
It is “What did Nigeria build with the money, and will those investments generate enough economic value to justify what future generations will have to repay?”
As the government continues to manage its debt portfolio and pursue higher revenue, the answer to that question will increasingly determine whether Nigeria’s rising debt becomes a foundation for future growth or another constraint on public finances.
