Core Crawls at 4.3%, Fuel and Food Run at 15.1%: Inflation a Rate Hike Barely TouchesCore Crawls at 4.3%, Fuel and Food Run at 15.1%: Inflation a Rate Hike Barely Touches
Key Highlights
- Kenya's 7.3% inflation averages two rates: core prices at 4.3% and volatile fuel and food prices at 15.1%.
- Mwenendo's arithmetic suggests that volatile items carry about 28% of the basket but about 57% of the headline rate.
- The December rate decision may matter less than a January tax cliff worth KSh 16.81 ($0.13) a litre.
Kenya's headline inflation of 7.3% is an average of two very different rates: core prices rising 4.3% a year and volatile food and energy prices rising 15.1%.
The figures suggest that the Central Bank of Kenya's 8.75% policy rate is aimed mainly at the calmer of the two. That matters because the bank meets again in December, and the loudest case, that inflation 0.2 points below the 7.5% ceiling demands a rate rise, may be pulling the wrong lever.
Two rates inside one number
The Kenya National Bureau of Statistics reported that annual inflation rose to 7.3% in October from 6.8% in September. Core inflation, which strips out volatile food and energy items, rose to 4.3% from 4.0%. Non-core inflation, which captures them, climbed to 15.1% from 14.0%, as Mwenendo reported at the time.
Those three numbers fix a fourth. If headline inflation is a weighted average of the two, October's figures imply that non-core items make up about 28% of the basket: 7.3 minus 4.3, divided by 15.1 minus 4.3, is 0.28. September's figures give the same answer. This is Mwenendo's arithmetic from rounded published rates, not a KNBS weight, but the match across two months suggests it is close.
On that reading, non-core items contribute about 4.2 of the 7.3 points, or 57%, from 28% of the basket. The other 72% of the basket, core prices, contributes about 3.1 points.
A policy rate already well above core
The Central Bank held its rate at 8.75% on 7 October. In its Monetary Policy Committee statement, it said it would continue "monitoring the evolution of global oil prices and any second-round effects on inflation", and cited the "stickiness of core inflation rates".
Against headline inflation of 7.3%, the real policy rate is 1.45 percentage points, down from 1.95 points when inflation was 6.8% in September. Against core inflation, it is 4.45 points. A policy rate more than four points above underlying inflation is not loose.
The risk case is still real. Core inflation has climbed from 3.4% in August to 4.0% in September and 4.3% in October. Fares are moving too: the matatu fare between Westlands and Kangemi in Nairobi rose to KSh 50 ($0.38) from KSh 40, a 25% increase, according to the KNBS price survey. That is how a fuel shock turns into a wage demand.
What a rate rise would and would not reach
A higher rate works by cooling borrowing and demand. It does not lower the price of diesel, which rose 32.5% on the year, or of Irish potatoes, which rose 34.9%, according to KNBS data as Citizen Digital reported.
It would, however, reach borrowers. Digital lenders had KSh 153.8B ($1.18B) outstanding by June, and the loan book grew 39.6% in six months, Mwenendo reported. The figures suggest that a rise would land on people already borrowing to cover food and fares far faster than it would land on the pump.
The calendar that matters more than December
Two dates sit ahead of the Central Bank's meeting. On 14 November the Energy and Petroleum Regulatory Authority sets new pump caps. If the monthly rhythm holds, as Mwenendo's explainer on pump prices set out, that review prices October's cargoes, a month in which Brent closed at a six-month high near KSh 15,160 ($116.72).
A rise of more than 0.2 points in the next inflation reading would take inflation above the 7.5% ceiling for the first time since 2023.
The second date is January. VAT on fuel is 8%, half the standard rate, after a 90-day extension in mid-October. At 16%, a litre of super petrol in Nairobi would cost KSh 243.77 ($1.88) against KSh 226.96 ($1.75) today, a rise of about 7.4%, holding everything else fixed.
What would change this reading
This is Mwenendo's interpretation, and three things would overturn it. Core inflation above 5%, the midpoint of the target, would suggest that demand is doing the work and a rate rise would then make sense. Fare increases that spread into services and wage settlements would point to second-round effects. A November Brent average below October's would ease the pump caps, though not food prices.
For now, the evidence suggests that the Treasury's decision on fuel VAT in January will move prices at the pump by more than anything the Central Bank can do in December.
In Summary
- Who sets the policy response?
- The Central Bank of Kenya, which holds its rate at 8.75%, and the Treasury, which decides on the fuel VAT rate.
- What do the figures show?
- October inflation of 7.3% combines core inflation of 4.3% with non-core inflation of 15.1%.
- When are the next decisions?
- EPRA sets pump caps on 14 November, the Central Bank meets in December and the 8% fuel VAT rate runs into January.
- Where is the pressure?
- Fuel, transport and food, which KNBS says make up more than 57% of the consumer basket.
- Why does it matter?
- Mwenendo's arithmetic suggests volatile items drive about 57% of the headline rate, which a policy rate does little to lower.
- How was the split worked out?
- Headline minus core, divided by non-core minus core, implies a non-core weight of about 28% for both September and October.
