Rain, a Tax Cut and a Steady Shilling: The Three Props Behind the CBK's Rate PauseRain, a Tax Cut and a Steady Shilling: The Three Props Behind the CBK's Rate Pause

Kenya's price rises are no longer only a pump story. The figures suggest higher transport costs are spreading into processed food and everyday goods, the slower-moving part of the shopping basket that interest rates are meant to restrain. That leaves the CBK heading into its December rate decision with less room than its own October forecast assumed, and with one of the three supports behind that forecast already giving way.

The forecast the CBK made on 7 October

When the Monetary Policy Committee held the Central Bank Rate at 8.75% on 7 October, it said overall inflation should stay within the 2.5% to 7.5% target range in the near term. It named what it was counting on: government measures including subsidies and the temporary cut in VAT on fuel, a stable exchange rate, and above-average rains from October to December that would bring food prices down.

The committee also said it would keep watching oil prices for possible second-round effects. That is the point at which a fuel shock stops being about fuel and starts lifting the price of everything that is made, moved or packaged with it.

Core inflation tells the real story

Three weeks later, the October figures arrived. Headline inflation rose to 7.3% from 6.8%, Mwenendo reported on Friday, leaving prices just 0.2 percentage points below the ceiling. Transport prices were up 17.1% on the year and food 10.2%.

The more telling number is core inflation, which leaves out the most volatile food and energy items. It rose to 4.3% in October, from 4.0% in September and 3.4% in August, according to the Kenya National Bureau of Statistics (KNBS) and the CBK. That is a climb of 0.9 points in two months in the part of the basket that is supposed to move slowly.

The CBK itself pinned September's core increase on processed foods, mainly milk, wheat products and edible oils. The October price survey shows the same items still climbing. The milk packet rose from KSh 61.23 to KSh 64.13, about 4.74% in one month, and a 2kg packet of wheat flour rose from KSh 181.11 to KSh 184.88 ($1.42).

Milk and flour are not fuel, but they depend on it. Dairies run cold chains and delivery lorries; millers truck grain in and flour out. When transport costs rise 17.1% in a year, the evidence suggests that cost is now reaching the supermarket shelf. That is the second-round effect the committee said it would watch for, and it is showing up in its own preferred measure.

Three props, three different fates

Mwenendo's reading is that the October forecast rested on three supports, and they are faring very differently.

**The rains. ** The committee expected an above-average short-rains season to lower food prices. So far prices have gone the other way: food inflation rose from 9.5% to 10.2%, and cabbages and Irish potatoes both cost more in October than in September.

Rain takes weeks to become harvests and fuller milk churns, and milk deliveries to processors had already fallen about 11% between June and August, as Mwenendo's dairy report showed. This support may still arrive, but it had not reached October's prices.

The fuel tax cut. The 8% VAT rate on fuel, half the standard 16%, was extended for a further 90 days in mid-October, which would carry it into January. It keeps pump prices lower than they would otherwise be, but it works as a discount, not a brake: it cannot stop prices rising when import costs climb. It also expires after the December meeting, so the committee will be voting with a known price jump waiting in the new year unless Parliament extends it again.

**The shilling. ** This is the support still standing. The currency has held near KSh 130 to the dollar, and CBK reserves of about KSh 1.91 trillion ($14.70 billion) cover 5.9 months of imports. A steady shilling stops imported goods from adding to the pressure.

But, as Mwenendo's analysis of Uganda's emergency rate rise set out, that steadiness depends partly on investors being paid enough to hold shillings rather than dollars.

The cushion is down to 1.45 points

That payment is shrinking. With the Central Bank Rate at 8.75% and inflation at 7.3%, the gap between the two is 1.45 percentage points, down from 1.95 points a month earlier. Another half-point rise in inflation with the rate unchanged would push the gap below one point.

The figures suggest this is the number that will weigh most on the committee. A narrow gap does not force a rate rise, but it makes a long hold harder to defend if core inflation keeps moving up, because markets can read it as tolerance of higher prices.

The case for holding steady

The strongest argument against a rate rise is that most of Kenya's inflation still comes from things the CBK cannot control. Non-core inflation, which captures food crops and energy, ran at 15.1% in October against 4.3% for core. A higher Central Bank Rate does not lower the price of crude oil or make it rain.

A rise would also land on borrowers already paying an average lending rate of 14.4% in September, according to the CBK. As an illustration, if banks passed a 0.5-point rise straight through, a trader with a KSh 1 million ($7,698) loan would pay about KSh 5,000 ($38.49) more in interest a year.

Private sector credit growth has only recently recovered to 10.6%, and the committee has just raised its 2026 growth forecast to 5.0% from 4.9%. Tightening now risks cooling a recovery the CBK has been nursing.

That case is strong against the headline number. It is weaker against core. A 4.3% core rate is still comfortably inside the target range, but it has moved in one direction for two months, and it is the part of inflation that interest rates are built to influence. Waiting until core is high would mean acting on Uganda's timetable: late, and therefore large.

November's price figures land before the vote

The order of events now matters. The Energy and Petroleum Regulatory Authority (EPRA) sets new pump price ceilings on 14 November. KNBS then publishes November inflation at the end of the month, a few days before the committee meets in December.

On Mwenendo's reading, two outcomes look most plausible. If November inflation stays under 7.5% and core steadies, the committee is likely to hold with a sharper warning. If inflation breaks the ceiling while core keeps rising, the case for a modest rise becomes hard to resist. This is Mwenendo's interpretation of the evidence, not guidance from the CBK.

For households and businesses, October's lesson is simple. The pump price is the cause everyone can see, but the milk packet and the flour bag are the signal the central bank will act on. Watch those, and you will know which way December is likely to go.
