Inflation Fell to 14.63%. Energy Costs More Than Doubled.

The National Bureau of Statistics published September's inflation figures on 15 October, and the headline was the best Nigeria has seen in years.

Headline inflation fell to 14.63%, down from 15.39% in August. That is a fourth consecutive monthly decline, and it is 6.35 percentage points below the 20.98% recorded in September 2025.

Then there is the number that matters more, and it is the one almost nobody quoted.

Month-on-month inflation was 0.06%.

Not 0.6%. Six hundredths of one per cent. In a single month, the general price level in Nigeria barely moved at all, down from 0.71% in August.

I want to give that its due before I complain about anything, because it is a genuine achievement and the people who took the painful decisions that produced it are entitled to say so. Month-on-month is the honest measure of what is happening right now; the annual rate is partly a story about last year. A month of essentially flat prices, after three years of relentless increases, is the first real evidence that the Nigerian price level has stopped running.

Now the other number.

Energy inflation more than doubled

In the same release, annual energy inflation came in at 10.85%, up from 4.69% in August. That is a rise of 6.16 percentage points, which is an increase of about 131% in the rate itself.

Month-on-month, energy prices rose 5.38% in September, after falling 0.36% in August.

So in the month when the general price level moved 0.06%, energy moved 5.38% — roughly ninety times as fast.

Petrol was selling between ₦1,400 and ₦1,430 a litre in Lagos and ₦1,400 to ₦1,450 in Abuja during September. Before the Middle Eastern conflict began, it was around ₦830. That is an increase of roughly 69% to 75%.

Why one line in a statistical table deserves its own article

Because energy is not a category of spending like clothing or recreation. It is an input to every other category.

Think about what it takes to get a tuber of yam from a farm in Benue to a market in Lagos. A truck burns diesel. The driver pays for that diesel. The market trader pays to store goods, often using a generator because the grid cannot be relied on. The woman who fries the yam pays for cooking gas. Every one of those people passes the cost forward, and the person at the end of the chain is you.

Economists call this a cost-push input, and it has a specific, unpleasant property: it works with a lag. A diesel price rise in September does not appear in food prices in September. It appears in October, November and December, as contracts reprice, as stock bought at the old cost runs out, as transporters renegotiate.

So the September report is showing you two different time horizons at once. The headline rate is telling you about the past — it reflects the naira stabilising, better harvests, and the simple arithmetic of comparing against a very high base a year ago. The energy line is telling you about the future.

They disagree. When they disagree, the input usually wins.

Where the energy number comes from

It comes from a war, and Nigeria has no vote in it.

Brent crude was trading around $108 to $111 a barrel on 20 October, a five-month high. It is up roughly 7.6% over the past month and about 76% over twelve months.

The drivers are not economic. Shipping data firm Kpler counted at least eighteen vessels coming under fire in the Gulf and the Strait of Hormuz over a two-week period. On 20 October Iran's Revolutionary Guard said it had struck two tankers. Houthi forces have attacked Saudi energy sites including an Aramco facility at Yanbu and the Shaybah oilfield. The US president has said American forces will not attack Iran before the November midterm elections, which the market reads as a deadline rather than a reassurance.

Forecast models compiled by Trading Economics put Brent near $113.86 by the end of the quarter and around $130.36 in twelve months. Forecasts are not facts, and oil forecasts are worse than most. But the direction of risk is clear enough.

Nigeria deregulated its fuel market in 2023. That means the pump price here tracks the global price, with no cushion in between. The same decision that ended the subsidy bill also removed the shock absorber.

The uncomfortable symmetry

Here is the part that ought to be at the centre of Nigeria's economic conversation and is not.

The rising crude price is simultaneously the best thing and the worst thing happening to this country right now.

It is filling federal accounts. Nigeria has been selling crude well above its budget benchmark for months, and external reserves hit about $55.07 billion in October, an all-time high. That is real money, and it is why the CBN felt able to cut its policy rate from 26.50% to 23% in September.

And it is raising the cost of moving a tuber of yam from Benue to Lagos.

Same barrel. Same war. One effect lands on the treasury, the other on the household. And because the windfall has not been saved or recycled into targeted relief — the Excess Crude Account holds a figure in the hundreds of thousands of dollars — the gain stays in one place and the pain stays in the other.

A country that earns more when oil rises has a natural mechanism for protecting its citizens from oil rising. Nigeria has that mechanism and is not using it.

What I will be watching

The energy line, every month. Not the headline. If energy inflation keeps climbing while headline falls, the gap is a debt that gets repaid in later months. If energy stabilises, the disinflation holds.

The month-on-month figure, not the annual one. The annual rate will keep falling for a while regardless, because it is measured against a terrible 2025. That is a base effect, not an improvement. Month-on-month is the live reading.

Food inflation specifically. Food is where transport costs land, and food is most of the budget for most Nigerian households. It is the clearest early-warning indicator available.

What a household should do

Treat the current calm as a window, not a new normal. If you have been putting off a purchase that depends on transport or imported inputs, the next few months carry more risk than the last few.

Budget fuel at the top of its recent range. Petrol has moved between roughly ₦1,370 and ₦1,450 in recent months. Plan on the higher figure and treat anything lower as a saving.

If you run a business, reprice on a schedule, not on every move. I have made this argument before and the September data strengthens it. Build a fuel assumption for the quarter at the upper end, hold it, and stop retraining your customers to expect instability.

And read the next CPI release properly. When the October figures land in November, the headline will probably have fallen again. Scroll past it. The energy and food lines are where the story is.

A month of 0.06% inflation is something Nigeria has not had in years, and the people who delivered it should take the credit. The question is whether it survives contact with a $130 barrel.

Right now, nothing in the policy response suggests anyone is planning for that.
