Kenya's annual inflation rate rose to 7.3% in October from 6.8% in September, the highest reading since July 2023, as diesel, petrol and food prices climbed, according to figures the Kenya National Bureau of Statistics released on Oct. 30.

The jump puts East Africa's largest economy in the same bind as many oil importers in Asia: an energy shock that central banks did not create but must keep from spreading into wages and other prices. For investors who hold Kenyan Treasury bills or shilling assets, the question is whether the Central Bank of Kenya, which held its benchmark at 8.75% on Oct. 7, will still see its stance as tight enough when it meets in December.

Fuel and food drive Kenya's inflation

Prices rose 0.7% in October alone, lifting the consumer price index to 157.60 from 156.47, the Star reported. The rate has risen in each of the past four months, from 6.4% in June.

Transport was the biggest mover. Transport costs were 17.1% higher than a year earlier, and diesel was up 32.5% and petrol 22.8% over the same period, Citizen Digital reported, citing the KNBS data. City bus and matatu fares, the minibus taxis most Kenyans use to get to work, were 18.2% dearer.

The month-on-month numbers were steep too. Average pump prices for petrol rose 6% from September to 227.85 shillings a liter, diesel 4.4% to 228.77 shillings and kerosene 14.7% to 220.88 shillings, according to the Star.

Food and nonalcoholic drinks, the heaviest item in the basket, were 10.2% more expensive than a year earlier. From September, a kilogram of Irish potatoes rose 2.5% to 125.06 shillings, cabbages 4.1% and a 500-milliliter packet of milk 4.7%, while sugar fell 1.2%. Food added 3.1 percentage points to the headline rate and transport 1.7 points, the Star said.

Underlying pressure is building as well. Core inflation, which strips out food, fuel and energy, rose to 4.3% from 4.0%. Noncore inflation reached 15.1%, up from 14.0%.

Central Bank of Kenya rate and the December test

When the Monetary Policy Committee left the Central Bank Rate unchanged on Oct. 7, it said overall inflation remained within its target range and was expected to stay there in the near term. It credited government subsidies and a temporary cut in value-added tax on fuel with damping prices, and pointed to a stable exchange rate.

The committee also said it would watch global oil prices for "any second-round effects on inflation" and stood ready to act if needed. It linked higher energy costs to the conflict in the Middle East. The October data, with core inflation rising for a second month, is the kind of spillover that statement described.

The bank's own surveys pointed the same way. In its September Market Perceptions Survey of 38 commercial banks, 14 microfinance banks and more than 200 other companies, respondents expected inflation to stay "slightly elevated" over the following three months because of food supply constraints and higher fuel and transport costs. They expected lending rates to remain broadly stable over the next year.

Other parts of the economy look steadier. The bank raised its 2026 growth forecast to 5.0% from 4.9% and kept 2027 at 5.3%. Lending by commercial banks to the private sector grew 10.6% in September, and the ratio of bad loans fell to 13.9% from 14.8% in June. Average bank lending rates were 14.4%.

Shilling, reserves and the import bill

Kenya's external position is the main buffer. Foreign exchange reserves stood at $14.70 billion, or 5.9 months of import cover, at the time of the October meeting. The shilling traded at 129.94 per U.S. dollar on Nov. 2, according to the central bank's daily exchange rate, and the 91-day Treasury bill rate stood at 8.75%.

Oil is eating into that cushion. The central bank estimated the current account deficit at 3.1% of GDP in the 12 months to August, up from 2.1% a year earlier, as fuel imports rose and diaspora remittances fell 1.3%. It projects a deficit of 3.2% of GDP for 2026 but still expects an overall balance of payments surplus of about $2.43 billion as capital inflows cover the gap.

Kenya is not alone in facing that pressure. Pakistan's central bank raised its policy rate to 12% as oil and wheat kept inflation above 10%, and Egypt lifted rates to 20% in a surprise move on Oct. 29, citing energy prices and regional risk.

The Monetary Policy Committee's next meeting is scheduled for December. Before then, the next KNBS consumer price report, covering November, will show whether October's rise in fuel and food prices carried over.
