Nigeria Inflation Slows to 14.63% in September, a Fourth Straight Decline

Nigeria's headline inflation slowed to 14.63% in September 2026 from 15.39% in August, the National Bureau of Statistics said on Thursday, extending a disinflation run to a fourth consecutive month and taking the annual rate to its lowest since the statistical agency rebased its index in January 2025.

The reading is a fall of 6.35 percentage points from the 20.98% recorded in September 2025. On a month-on-month basis, prices rose just 0.06% in September, down sharply from 0.71% in August.

The numbers behind the slowdown

The consumer price index edged up to 146.38 points in September from 146.30 points in August. The annual rate fell faster than the monthly rate because it is measured against a high base from a year earlier, when prices were rising quickly. Food price relief did the heaviest lifting: the bureau reported that food prices retreated during the review month, easing pressure on household budgets.

Even so, the report contained an important counter-signal. Core inflation, which strips out volatile farm produce and energy, rose on a month-on-month basis, and urban inflation accelerated. That combination suggests the easing in the headline number is being driven mainly by food and base effects rather than by a broad, broad-based cooling of demand pressures.

Why the mix matters for policy

The September print lands weeks after the Central Bank of Nigeria delivered its largest-ever cut to the monetary policy rate, reducing the benchmark by 350 basis points to 23% on the strength of three earlier months of disinflation. A fourth decline reinforces the case the bank set out for easing.

The core and urban readings qualify that story. If underlying price pressures are rebuilding even as the headline rate falls, the committee will be cautious about extending cuts at a pace that could revive inflation later. Nigeria's cost-of-living crisis is also far from resolved: lower inflation means prices are rising more slowly, not that they are falling. Many staple foods remain far more expensive than they were two years ago.

What households and businesses should read

For households, a slower rate of increase offers little immediate relief if wages are not keeping pace, because the price level remains historically high. For businesses, the more consequential question is the direction of interest rates and the exchange rate, which feed into borrowing costs and imported input prices.

The naira has been relatively stable, and the harvest season is under way, both of which support continued moderation. Fuel and transport costs, however, remain a structural driver of price pressure that monetary policy cannot easily reach.

What to watch

The October and November inflation prints will show whether the core and urban uptick was a one-month anomaly or the start of a firmer trend. Also watch the central bank's next committee meeting: another reduction would signal confidence that disinflation is durable, while a pause would confirm that policy makers are watching the same underlying pressures the September data exposed.
