The Price Of Filling The Gap: Inside Nigeria’s Expanding Domestic Borrowing Drive

By OBIOMA TORI

An Expanding Debt Burden in a High-Deficit Economy

NIGERIA’S domestic borrowing has continued to rise as the Federal Government confronts an increasingly difficult fiscal arithmetic: expenditure needs remain high, revenue growth has yet to eliminate the financing gap, and borrowing has become one of the principal instruments for keeping the budget funded.

By the end of the first quarter of 2026, Federal Government domestic debt had reached ₦82.9 trillion, according to the latest public debt data referenced in the report.

The figure represented the largest share of Nigeria’s total domestic debt stock of ₦87.4 trillion, with states and the Federal Capital Territory accounting for approximately ₦4.5 trillion.

The quarterly and annual increases point to a clear direction.

Nigeria is drawing more heavily on the domestic financial system to finance its fiscal obligations.

That pressure is expected to intensify as the 2026 fiscal deficit is projected at ₦31.5 trillion, or 6.4 per cent of GDP.

The projected deficit is substantially higher than the ₦13.1 trillion gap recorded in the 2025 fiscal framework.

The implication is straightforward: unless revenues rise significantly or expenditure falls, the government will need to continue finding new sources of financing.

Treasury Bills Reveal the Urgency of Government Financing Needs

One of the clearest indicators of the government’s growing borrowing requirement is the sharp rise in Treasury Bill obligations.

The stock of Nigerian Treasury Bills rose to ₦16.6 trillion by the end of March 2026.

That represented an increase of ₦2.7 trillion from the preceding quarter.

On a year-on-year basis, the obligations expanded by more than 30 per cent.

The increased use of Treasury Bills suggests a growing reliance on short-term borrowing to meet financing requirements.

Such instruments can help government raise funds quickly. Yet their shorter maturity structure means they create a continuing need for refinancing.

As Treasury Bills mature, the government must either repay investors or issue new instruments to replace them.

When interest rates are high, repeated refinancing can add significantly to borrowing costs.

This creates an important policy concern.

The government may be able to access funds today, but the structure of that borrowing determines how much fiscal pressure returns in the future.

Bonds Still Carry the Largest Share

While Treasury Bills recorded the sharpest increase, FGN bonds remained the foundation of Nigeria’s domestic debt market.

The Federal Government’s bond obligations stood at ₦63.5 trillion, accounting for about 76.6 per cent of its domestic debt.

The bond stock remained broadly stable during the first quarter but was higher than its level a year earlier.

Other instruments, including Sukuk, savings bonds and promissory notes, accounted for almost ₦2.9 trillion.

This combination gives the government access to different classes of investors and different maturity structures.

However, the diversity of instruments does not remove the underlying fiscal problem.

Every borrowing instrument eventually creates an obligation that must be serviced.

The larger the debt stock, the more important interest costs become.

The Race to Meet the 2026 Financing Target

The government’s borrowing programme has already demonstrated the scale of its domestic financing requirements.

Bond auctions raised approximately ₦5.6 trillion during the period under review, nearly twice the ₦2.8 trillion generated during the comparable period in 2025.

Net Treasury Bill issuance added roughly ₦3 trillion.

The increase indicates that the government has been far more active in the domestic debt market.

Even so, a sizeable financing gap remains when compared with the ₦29.2 trillion domestic borrowing target contained in the 2026 budget.

This gap does not necessarily mean the government will fail to meet its financing needs.

Alternative sources of domestic funding could supplement bond and Treasury Bill issuance.

Nevertheless, the figures illustrate the magnitude of the challenge facing the Debt Management Office and fiscal authorities.

They must raise large amounts of money without destabilising the market that provides the financing.

When Government Competes With Businesses for Money

The greatest economic consequence of rising domestic borrowing may emerge outside government itself.

The Federal Government borrows from the same broad pool of financial resources that businesses depend on for investment and expansion.

Banks, pension funds and other institutional investors must decide where to allocate their capital.

Government securities often offer attractive returns and carry relatively low credit risk.

For financial institutions, lending to the government can therefore appear safer than extending credit to businesses operating in an uncertain economic environment.

The consequence is the risk of crowding out.

Businesses may find that less credit is available.

When credit is available, the cost may be higher.

This can affect manufacturers seeking to expand production, farmers requiring working capital, entrepreneurs attempting to start businesses and larger companies planning new investments.

High borrowing costs can eventually slow investment and weaken job creation.

Debt Sustainability Is More Than a Debt-to-GDP Ratio

On the surface, the Federal Government’s domestic debt remains within ratios that may appear manageable when measured against GDP.

The debt represented an estimated 19.2 per cent of 2025 GDP on a standardised basis.

Based on projected economic growth for 2026, the ratio could decline to approximately 16.1 per cent.

However, debt-to-GDP ratios tell only part of the story.

A country may carry a moderate debt ratio and still experience serious fiscal pressure if government revenues are insufficient to meet interest and repayment obligations.

For Nigeria, the more critical question is whether revenue growth can keep pace with rising borrowing and debt-service costs.

Economic growth is helpful.

Yet growth that does not translate into stronger government revenues may not sufficiently reduce fiscal vulnerability.

The Search for a Sustainable Balance

Domestic borrowing is not inherently harmful.

Governments borrow to finance infrastructure, manage temporary revenue shortfalls and support economic programmes.

The effectiveness of borrowing depends largely on its cost, purpose and sustainability.

Borrowing to finance productive investments that expand the economy and generate future revenues can strengthen long-term fiscal capacity.

Persistent borrowing to finance recurrent gaps, however, can create a cycle in which new debt is increasingly needed to manage the consequences of previous obligations.

Nigeria’s current fiscal challenge lies in finding a balance.

The government must continue financing essential public services and development priorities.

At the same time, it must prevent rising domestic borrowing from pushing interest rates higher and reducing the availability of credit to the private sector.

A Warning From the Domestic Debt Numbers

The rise of Federal Government domestic debt to ₦82.9 trillion is therefore a significant indicator of Nigeria’s broader fiscal condition.

It reflects the widening gap between public expenditure and available revenue.

It also highlights the growing importance of debt management as a tool of economic policy.

The central challenge now extends beyond raising the funds required to finance the 2026 budget.

Nigeria must also ensure that its borrowing does not become a drag on the economy it is intended to support.

That will require stronger revenue mobilisation, greater discipline in public expenditure, more efficient use of borrowed funds and a debt strategy that carefully balances domestic and external financing.

Without those adjustments, the government could continue filling its fiscal gap through domestic borrowing while creating another problem elsewhere in the economy: higher borrowing costs, reduced private investment and slower growth.

In that sense, Nigeria’s rising domestic debt is not simply a story about how much government owes. It is increasingly a story about who gets access to the nation’s financial resources, what those resources cost, and whether borrowing today will strengthen—or constrain—the economy tomorrow.
