Nigeria’s plan to offer N5.75 trillion in Federal Government bonds during the final quarter of 2026 has renewed concerns about the cost of domestic borrowing and the growing share of government revenue required to service public debt.
The Debt Management Office (DMO) has scheduled three bond auctions between October and December, extending a year in which the Federal Government has substantially increased its borrowing activities in the domestic capital market.
According to the DMO’s provisional issuance calendar, the government plans to offer N1.75 trillion on October 19, followed by N2 trillion on November 16 and another N2 trillion on December 14.
The proposed issuance comes as Nigeria faces pressure to finance budgetary obligations while managing an existing debt portfolio that stood at N166.79 trillion at the end of June 2026.
For the Federal Government, the central challenge is not simply securing additional financing but determining how much future revenue will be committed to interest payments and debt repayments.
Naijaonpoint‘s analysis shows that the fourth-quarter programme could create substantial additional interest obligations if the planned offers are fully subscribed and allotted.
The government intends to reopen three existing bonds carrying coupon rates of 19%, 16.79% and 15.45%, with maturities extending from 2034 to 2038.
The February 2034 bond, which carries a 19% annual coupon, accounts for N1.5 trillion of the planned offers.
The September 2036 bond carries a 16.79% coupon and represents N2.8 trillion, making it the largest component of the programme.
The June 2038 bond, with a coupon of 15.45%, accounts for the remaining N1.45 trillion.
Applying these coupon rates to the proposed issuance amounts produces an illustrative annual interest obligation of approximately N979 billion if the entire N5.75 trillion is allotted.
The calculation does not represent a confirmed government expenditure commitment because actual allotments may differ from the advertised amounts.
The effective borrowing cost will also depend on the auction prices and yields accepted by the DMO, while the timing of issuance will determine the interest payable during individual financial years.
Nevertheless, the estimate illustrates the scale of the recurring payment obligations that can accompany large domestic bond programmes.
Nigeria’s existing debt-service burden makes this particularly important.
The International Monetary Fund projected that Federal Government interest payments would absorb approximately 53.7% of federal revenue in 2026, compared with 53.2% in 2025.
This implies that more than half of projected federal revenue could be required for interest payments alone, leaving a smaller proportion available for other spending priorities before additional financing needs are considered.
The IMF’s measure relates specifically to interest payments and Federal Government revenue. It should not be confused with total debt service, which also includes principal repayments, or with the revenue of all tiers of government.
The fiscal implications become more significant when borrowing is used to meet obligations that do not generate sufficient future revenue or economic returns.
Borrowing for productive infrastructure can support economic activity and strengthen the government’s long-term revenue potential, but the benefits depend on project execution and the returns generated.
Where additional borrowing primarily refinances existing liabilities, the immediate benefit may instead be improved liquidity or a more manageable repayment schedule.
The DMO’s issuance calendar does not establish how much of the proposed N5.75 trillion represents fresh borrowing rather than refinancing.
That distinction will be necessary to assess the programme’s effect on Nigeria’s net debt position.
The latest plan follows a sharp increase in bond allotments during the first nine months of 2026.
Between January and September, the Federal Government allotted approximately N7.15 trillion in bonds, compared with N3.48 trillion during the corresponding period of 2025.
The increase of about 106% indicates that the government has relied more heavily on domestic bond auctions during the year.
However, higher gross issuance does not automatically translate into an equivalent increase in outstanding public debt, particularly where part of the proceeds is used to repay maturing securities.
Nigeria’s total public debt increased from N159.35 trillion at the end of March to N166.79 trillion at the end of June, according to the DMO.
Domestic obligations accounted for N91.59 trillion of the June debt stock, equivalent to approximately 54.9% of the total.
The increasing volume of government securities also has implications for banks, pension funds, asset managers and other institutional investors.
Federal Government bonds provide investors with relatively predictable coupon payments and exposure to sovereign credit risk.
When yields are attractive, financial institutions may allocate more resources to government securities, potentially reducing the funds available for lending to private businesses.
This crowding-out effect is not inevitable, but it becomes an important consideration when government financing requirements remain elevated.
The IMF has previously identified the relationship between government borrowing and bank lending as a concern for Nigeria’s financial system.
For businesses, particularly manufacturers and smaller enterprises, the availability and cost of credit remain important determinants of investment and expansion.
A sustained preference for government securities could complicate efforts to increase financing for productive private-sector activities.
The fourth-quarter bond programme will therefore test both investor appetite and the government’s ability to manage its financing costs.
Strong demand could support successful auctions, but the yields investors require will determine the cost at which the government obtains the funds.
Conversely, weaker demand could require the DMO to accept higher yields, reduce allotments or adjust subsequent offers.
The October 19 auction will provide the first indication of how investors are responding to the latest borrowing programme.
Subscription levels, accepted yields and final allotments will be particularly important in determining whether the government’s financing objectives can be achieved without materially increasing borrowing costs.
For Nigeria, the longer-term issue remains the relationship between debt accumulation, government revenue and economic growth.
A sustainable borrowing strategy requires not only access to financing but also sufficient revenue generation and effective use of public resources to meet future obligations.
With the Federal Government preparing to offer another N5.75 trillion in bonds, the cost of servicing those obligations will remain a central consideration for fiscal policy, capital market investors and businesses competing for domestic financing.
