Nigeria's interest bill hit N7.7trn in six months. The building budget got N700bn.

The Federal Government of Nigeria paid N7.7 trillion in interest on its debt during the first six months of 2026, according to the World Bank's 2026 Nigeria Development Update. That is 37.5% more than the N5.6 trillion it paid over the same period in 2025 — an increase of N2.1 trillion in twelve months.

Federal revenue over those six months was N6.2 trillion. The interest bill therefore exceeded everything the government collected by N1.5 trillion, or about 24%.

The World Bank attributes the rise in interest costs to high domestic borrowing rates. The report in question is titled "Beyond the Federal Purse: How Higher Revenues Reshaped State Priorities," and the federal figures reported here come from within a study whose main subject is how state governments have responded to larger allocations.

In Simple Terms

The government borrows money. Every year it pays a fee for holding that money, separate from paying the money back. That fee is interest, and in the first half of this year the fee came to more than the government earned.

It is worth being precise about what that does and does not mean. It does not mean Nigeria spent every naira it earned on interest and nothing else — the government also spent on salaries, running costs and projects, funded by borrowing on top of its revenue. It means the interest line on its own was larger than the revenue line on its own.

The Money

Total federal spending in the half year was N16.1 trillion, against N6.2 trillion of revenue. The difference between what came in and what went out was N9.9 trillion. (Derived. The source does not publish an official deficit figure, and the formal deficit may differ once all financing items are counted.)

Where the N16.1 trillion went, shrunk to N100:

For every naira that went into building something, roughly eleven naira went into interest. (Derived.)

The Numbers

Interest: N7.7 trillion, or 3.1% of GDP. Up from N5.6 trillion and 2.5% of GDP. Both the naira amount and the share of the economy rose, which means the debt burden grew faster than national output.

Revenue: N6.2 trillion, or 2.5% of GDP. Up by more than 72% on the same period last year. That implies the government collected roughly N3.6 trillion in the first half of 2025. (Derived, and approximate — "more than 72%" sets a floor, not an exact rate.) The growth came from oil receipts, stronger corporate tax collections and higher independent revenue. Customs revenue held stable and VAT collections stayed comparatively flat.

Interest as a share of revenue: about 124%, down from about 156%. (Derived.) Because revenue grew roughly twice as fast as interest, this ratio improved year-on-year even as the absolute bill rose. Both statements are true at once.

Capital spending: 0.3% of GDP, about N700 billion. Down from 1.0% of GDP — roughly a two-thirds cut in its share of the economy.

Personnel: N4.2 trillion, up from N3.7 trillion after wage adjustments, but unchanged at 1.7% of GDP.

Total spending: N16.1 trillion, up from N14.6 trillion, yet slightly down as a share of the economy, from 6.6% to 6.5%. Spending rose about 10% in naira while the economy in naira terms grew faster. (Derived.)

Follow the Money

Beyond what the source states, the distribution of effects below is Rainingmoney's reading.

Lenders to the Nigerian government are the direct recipients. N7.7 trillion left the treasury and went to whoever holds the debt — predominantly domestic holders, given that the World Bank points to domestic borrowing costs as the driver. Banks, pension funds and other institutional holders of Nigerian government securities are on the receiving end of that transfer.

Government workers saw pay rise in naira terms, with personnel costs up N500 billion after wage adjustments.

Anyone waiting on public infrastructure absorbed the squeeze. Roads, power projects, hospitals and schools are funded from the capital line, and the capital line is the one that fell.

Private borrowers share the underlying condition. The same high domestic interest rates that make government borrowing expensive make business and consumer credit expensive.

Future taxpayers carry what is not paid now. Borrowing to cover a shortfall moves the cost forward in time rather than removing it.

The Bigger Picture

Nigeria's fiscal story over the past two years has been one of improving revenue. More than 72% growth in half-year collections is a substantial result, and it reflects reforms that were politically costly.

The difficulty is that the revenue gains are arriving alongside an interest bill that is compounding. Debt taken on at high domestic rates keeps generating cost regardless of how well collections go, and the economy has to grow faster than that cost for the burden to shrink. On the GDP measure, it did not: interest rose from 2.5% to 3.1% of output.

There is also a signal in the source itself. The federal numbers sit inside a report about how higher revenues reshaped state government priorities. The headline question the World Bank set out to examine was what the states did with more money — the federal picture is the backdrop to it.

The Jargon

Interest payment — the fee for holding borrowed money, separate from repaying it. Total debt service is interest plus principal repayment, so it is larger than the N7.7 trillion discussed here.

Capital expenditure — spending that builds or buys lasting assets: roads, power plants, equipment.

Recurrent expenditure — the cost of running the government year to year: salaries, overheads, interest.

Independent revenue — money government agencies generate themselves, such as fees and charges, rather than receiving from shared tax pools.

Share of GDP — a figure expressed against the size of the whole economy, which lets you compare across years when inflation and growth change what a naira represents.

VAT — value added tax, the levy added to most goods and services.

What Happens Next

Known. Interest costs rose to 3.1% of GDP in the first half of 2026. Capital spending fell to 0.3%. Revenue grew more than 72%. These are reported figures covering January to June.

Possible. Capital spending may recover in the second half, as Nigerian capital releases frequently cluster later in the year, so the full-year figure could look materially different. If domestic interest rates ease, the interest bill moderates without further policy action. If revenue keeps outpacing interest, the ratio continues improving.

Unknown. The source gives no fiscal deficit figure, no total debt stock and no debt-to-GDP ratio, so the full balance-sheet position is not visible from these numbers. It attributes no explicit warning or recommendation to the World Bank. Nothing here indicates how the second half will go.

Rainingmoney's Take

Analysis, not reporting.

The honest reading of this data is more mixed than the headline allows. Revenue growing at twice the pace of interest is the fiscal system working — collections improving faster than the cost of past borrowing compounds. A year ago the same comparison would have looked worse.

What should concern a reader is not the interest line but the capital line. Interest is the price of decisions already made, and little can be done about it in a single half year. Capital spending is a present choice, and cutting it to roughly a third of its former share of the economy means fewer of the assets that generate the future output and future tax base needed to carry the debt.

A government can service expensive debt for a long time while still investing. The risk is the configuration where it services the debt by not investing, because that trades a problem now for a larger one later. One half of one year does not establish that pattern. The full-year capital figure will say a good deal more.
