CBK is holding. Inflation isn't.
The Central Bank Rate was 8.75% in April. It is 8.75% now. Inflation has gone from 4.4% to 6.6% in between. The gap between those two numbers is the most important thing in Kenyan finance right now, and almost nobody is explaining what it actually does to you.

The Hook
What happenedOn 11 August 2026, the Monetary Policy Committee of the Central Bank of Kenya met and did nothing. The Central Bank Rate stayed at 8.75% — the same level the committee retained back in April.
Three weeks later, the inflation figure for August came in at 6.59%. In March it was 4.39%.
Holding a rate is not a non-event. It is a decision. And this one is getting harder to make every month.
The Kenya Angle
Why Kenya caresHere is the chain. Follow it once and you will never need to memorise it again.
Start with what the CBR is for. The Central Bank Rate is the price CBK charges banks for short-term money. It is the anchor everything else is priced off — interbank lending, your bank's lending rate, what a Treasury bill pays. When CBK moves it, it is trying to speed the economy up or slow it down.
Now the part people skip. The number that matters is not 8.75%. It is 8.75% minus inflation — the real rate. That is what money actually costs once you account for the fact that shillings buy less each month.
In March, inflation was 4.4% and CBK's own April statement noted it was sitting below the midpoint of the 5±2.5% target band. A CBR of 8.75% against that was a genuinely tight setting — real money cost you over four points.
By August, inflation was 6.59% and climbing for the sixth straight month. The CBR had not moved. So the real rate quietly halved, to about 2.2 points. CBK did not loosen policy. Inflation loosened it for them.
What that does downstream. Cheaper real money is not automatically bad — the same April statement showed private sector credit growth picking up to 8.1% in March from 7.4% in February, with lending flowing to construction, trade and agriculture as bank lending rates came down. That is the loosening working as intended.
But it cuts both ways:
- If you are borrowing, you are winning right now. A loan priced off an 8.75% anchor, repaid in shillings losing 6.6% of their value a year, is cheaper in real terms than it was in March.
- If you are saving, you are losing more quietly. A savings account paying you less than 6.59% is shrinking your money while the balance goes up. Most of them are.
- If you are a bank, the calculation is more interesting — and it is where the exam question lives. Cheaper money means more lending, which means volume. But it also compresses what you earn on each shilling lent. How banks actually make money is the other half of this story.
And the pressure that makes October hard. Look at the composition, not just the headline. CBK's April statement broke March inflation into core at 2.1% and non-core at 10.8% — the latter driven by vegetable prices. That split matters enormously. Core inflation is demand: too much money chasing too few goods, and a central bank rate is the right tool for it. Non-core is food and fuel: supply shocks, weather, global energy. Raising rates does not make it rain.
If the climb from 4.4% to 6.6% is mostly non-core, hiking punishes an economy for something a rate cannot fix. If core has started moving too, holding becomes indefensible. That is the whole argument in the room on 7 October.
What to Watch
What matters next1. The core/non-core split in the September CPI. This is the one. If core inflation is still near 2%, CBK can hold and call the climb a supply story. If core has drifted up toward 3.5–4%, the argument for holding collapses. KNBS publishes at the end of each month.
2. The 7 October MPC decision — and the language, not just the number. CBK has held through this stretch. Watch for the shift from "expected to remain within the target range" to anything hedged. Central banks warn before they move.
3. The upper bound. The target is 5% plus or minus 2.5 — so 7.5% is the ceiling. At 6.59% and rising roughly 0.1 a month, arithmetic gets CBK there around the turn of the year. A central bank that breaches its own target band has a credibility problem, and credibility is most of what a central bank has.
4. Private sector credit growth. It was 8.1% in March and rising. If it keeps accelerating while inflation climbs, that is the demand-side signal that turns a supply story into a monetary one.
Interview Edge
How to use it"The CBK has held rates while inflation has risen all year. Is that the right call?"
They are not testing whether you agree. They are testing three things, in order:
- Do you know the difference between the nominal rate and the real rate? Most candidates answer entirely in nominal terms and reveal they have never thought past the headline.
- Do you know what a rate can and cannot fix? Anyone who says "inflation is up so they should hike" without asking what kind of inflation has skipped the actual analysis.
- Can you hold two things at once? The strongest answer names the trade-off rather than picking a side.
Give them a view. A candidate with no view is harder to hire than one with a defensible wrong one — but attach it to a condition, because that is what real analysts do.
"It has been defensible so far, but it is getting harder. Holding at 8.75% while inflation went from 4.4% to 6.6% means the real policy rate has roughly halved — so policy has loosened without CBK actually cutting. The reason that has been the right call is composition: most of the climb has been non-core, food and fuel, and a rate hike does not fix a supply shock, it just slows down an economy that is finally lending again. Private sector credit growth was picking up. But with the target band topping out at 7.5%, that argument has a shelf life. I would be watching core inflation in the September print — if core starts moving, this stops being a supply story and CBK has to act."
"So would you hike in October?"
"Not yet — I would signal. Hiking into a supply shock costs you growth and does not fix the cause, and credit growth is still young. But I would change the language to make clear the committee is prepared to move, because the cheapest tightening a central bank can do is the kind it only has to talk about. If core inflation is still moving by the December print, then yes."
"What if you are wrong and inflation breaks 7.5%?"
"Then the cost is credibility, which is more expensive to rebuild than growth is. That is the real risk in my position and it is why I would want the September core number before committing."

What exactly does the Central Bank of Kenya do?
Not "print money" and not "run the economy." CBK has four jobs, and once you can name them in order, most Kenyan financial news stops being confusing.
Inflation isn't "things getting expensive"
It's a rate of change in a basket you didn't choose — which is why the official figure and your own experience of prices can both be right at the same time.
How Kenyan banks actually make money
Three income lines, one of which everybody forgets. Once you can read a Kenyan bank's results in those three parts, you can read any bank's results anywhere.
