Nigeria’s headline inflation fell to 14.63% in September 2026, down from 15.39% in August and 20.98% in September 2025, in response to the National Bureau of Statistics (NBS, 15 October 2026).
That is a drop of 0.76 proportion factors in a single month and 6.35 factors in a yr. It is the fourth straight month-to-month decline.
The headline is nice information.
September fall got here solely from meals prices dropping in the course of the harvest. The prices that don’t rely on the harvest went up sooner.
What fell?
Food. On a month-on-month foundation, meals prices fell 1.55% in September, after rising 1.02% in August. The NBS named grains, rice, eggs, onions, palm oil, greens, potatoes, plantain and tomatoes. Month-on-month means the change from one month to the subsequent, with out comparability to the earlier yr. A unfavorable quantity means prices fell.
The rural figures inform the identical story. Rural prices fell 0.89% month-on-month in September. Urban prices rose 0.53%. Farmers promote at harvest, and villagers really feel the worth drop first. Cities pay for transport, lease, energy and providers, and people prices didn’t fall.
So, month-on-month inflation got here in at simply 0.06%. Multiply that tempo throughout twelve months and also you get an annual charge of lower than 1%. Nobody ought to count on that to proceed. Harvest prices fall yearly round this time and climb once more within the lean season.
What went up?
Core inflation. Core strips out farm produce and vitality, the 2 most unstable elements of the basket. It is one of the best information to underlying worth stress: rents, college charges, transport fares and manufactured items all rose. Core rose 1.11% month-on-month in September, after a fall of 0.06% in August.
Do the arithmetic. A 1.11% month-to-month rise, compounded over twelve months, is 1.0111 raised to the twelfth energy, or about 1.142. That is an annualized tempo of 14.2%. The printed annual core charge is 12.95%. In September, then, the underlying tempo ran above the annual determine. One month doesn’t make a pattern. It does let you know that the September headline flatters the image.
Food inflation on an annual foundation remains to be 19.59%, little modified from 19.57% in August (Reuters, 15 October 2026). A Nigerian family that spends half its revenue on meals is going through prices 20% increased than a yr in the past.
Why does the vitality line matter now?
Because petrol is dear and oil is excessive. Brent crude traded above $100 a barrel in mid-October, and a few Abuja filling stations raised pump prices to about N1,405–N1,409 per liter. NNPC’s N66-per-litre buyer reduction runs solely till 31 October.
The World Bank’s October 2026 Nigeria Development Update places it plainly. Inflation fell from 27.6% to fifteen.2% between January and December 2025, then “stalled” at round 15.5% in 2026, which the Bank says is greater than double the speed of peer international locations. Its headline purpose is the vitality shock. Fuel feeds into transport and transport feeds into the worth of every part else. That is how vitality prices find yourself in core inflation with a lag.
What does this imply for CBN?
The CBN minimize the Monetary Policy Rate to 23% in September. Against September inflation, the actual coverage charge is 23 minus 14.63, or 8.37 proportion factors. That is a large cushion. On paper, it leaves room for one more minimize.
The market charge is the higher check. At the 14 October Treasury invoice public sale, the 364-day cease charge was 15.90%. Subtract 14.63% and the actual return on a one-year invoice is 1.27 proportion factors. Strip out the harvest impact and use the core tempo of about 14.2%, and the cushion remains to be skinny. Investors are accepting a small actual return as a result of they imagine inflation will preserve falling. If core retains rising, that perception breaks, and yields will return up regardless of the CBN does with the MPR.
What does this imply for the Federal Government?
This is the more durable half. Nigeria votes in January. The World Bank’s October 2026 Africa Economic Update raised its 2026 development forecast for Nigeria to 4.3%, and in the identical report warned that “rising pre-election spending ahead of the 2027 elections” is a draw back threat. The IMF raised its 2026 forecast to 4.2% and has urged Nigeria to withstand calls to revive blanket gas subsidies.
The fiscal place did enhance. The World Bank says web revenues rose to 4.2% of GDP, or ₦10.5 trillion, within the first half of 2026, helped by FX and petrol reforms and decrease deductions from oil income. It additionally expects spending pressures to rise within the second half. Revenue raised by reform after which spent on campaign-season handouts places cash into the identical markets the place core prices are already rising.
Two issues to do earlier than the subsequent print.
First, the CBN ought to maintain at its subsequent assembly. The actual coverage charge is extensive, but one month of falling meals prices is just not proof that underlying inflation is overwhelmed. Cutting right into a rising core quantity repeats the error of studying the harvest as coverage success. A pause prices lower than a reversal in Q1 2027.
Second, the Federal Government ought to publish a pre-election spending ceiling and preserve the gas market open. Establishing a spending cap, publishing that quantity in public, quarter by quarter, is the most cost effective solution to present buyers that the income positive aspects of 2026 won’t leak away in December and January.
Blanket gas subsidies would decrease the pump worth for just a few months and push the fee onto the price range and the naira. The ₦66 reduction ends on 31 October. Let it finish and intention any assist at transport for low-income staff fairly than at each litre bought.
Watch the October core quantity.
October CPI will let you know whether or not September was a harvest month or a turning level. Watch core month-on-month. If it falls again under 1%, the disinflation is actual and the CBN can ease once more in 2027. If it stays above 1%, the 14.63% headline was a harvest low cost.
