A committee in Pretoria met on 23 September and your bond instalment moved while you slept. Here’s what the repo rate is, why it went up, what it costs a homeowner, and why some JSE shares wince while others smile.

You’ve heard “the repo rate” on the news a hundred times and probably nodded along without being sure what it does. Fair enough. But on 23 September the Reserve Bank raised it, and your bond, your car payment and your share prices all felt something. Some of it shows up in your banking app. Some of it hides inside the JSE.
So let’s open the box.
Spoiler: nobody in that room asked about your school fees.
Why your debit order moved while you slept
Picture it. You wake up, check your banking app, and the bond instalment looks different. You didn’t do anything. Nobody phoned you. A committee of people you’ve never met sat in a room in Pretoria, and your monthly budget shifted.
On 23 September 2026, the Reserve Bank’s Monetary Policy Committee, the MPC, voted to raise the repo rate by 25 basis points to 7.25%. The decision was unanimous and took effect on 25 September.
A basis point is one hundredth of a percent. So 25 basis points is a quarter of one percent. Small number. Big reach.
What is the repo rate, and how is prime linked?
The repo rate is the rate at which the Reserve Bank lends money to the commercial banks. Repo is short for repurchase, but you don’t need the mechanics. Think of it as the wholesale price of money in South Africa.
Banks don’t lend you money out of thin air. They borrow it, mostly from depositors and from each other, and the repo rate sets the floor under all of that.
Then the banks add their own margin, and that gives you the prime lending rate. Prime drives your bond, your overdraft and a lot of car finance. After this hike, prime went from 10.5% to 10.75%.
The chain is short. Reserve Bank moves repo. Banks move prime. Your debit order moves.
Why does the Reserve Bank do this at all? Its main job is protecting the value of the rand, which really means keeping inflation under control. The target is 3%, with a tolerance band of one percentage point either side. Raise rates and borrowing costs more, spending cools, and price rises slow down. That’s the theory. It works slowly, and not always neatly.
Why the Reserve Bank hiked the repo rate this time
Stick to what the Reserve Bank itself said.
Headline inflation was 4.4% in August, up from 4.3% in July, according to Stats SA. That’s inside the band, but above the 3% the Bank actually wants.
The bigger worry is where it’s heading. The Bank says fuel prices are rising again after easing between June and August. It expects inflation to climb above 5% later this year and early next year, then settle back near 3% towards the end of 2027.
It also pointed at the outside world: conflict in the Middle East, disruption to oil shipping, and central banks abroad raising their own rates. Meanwhile the economy shrank by 0.2% in the second quarter. That’s the tension. Hiking helps with prices and hurts with growth.
The Bank’s own forecast has the repo rate broadly stable for the rest of this year, with cuts later once inflation comes down. A forecast, not a promise. The next meeting is 19 November 2026.
What a 25 basis point repo rate hike costs a homeowner
Numbers only matter when they hit your pocket, so here’s the pocket.
Take a R1 million bond over 20 years at prime. Before the hike, at 10.5%, the instalment was about R9,984 a month. At 10.75% it’s about R10,152. That’s around R168 more, every month. Think of it as one decent takeaway dinner for two, every month, for 20 years, sent to the bank.
A R1.5 million bond goes from about R14,976 to about R15,228, roughly R252 more a month. Over the life of that bigger bond, that’s about R60,000 extra in interest if the rate stayed put the whole way.
Two honest caveats. Those figures assume you borrowed the full amount at exactly prime, with no deposit and no fees. Plenty of people pay a bit above or below prime, so your number will differ. And rates don’t sit still for 20 years.
For perspective, prime was 11.75% in 2023. Even after this hike, it’s below that peak.
The flip side is savers. Cash in a bank account or money market fund generally earns more when rates rise. Every product is different, so check your own.
What a repo rate hike does to JSE shares
Rates don’t hit every share the same way. Here’s the balanced version, not a pick list.
Bear case for higher rates. Companies carrying a lot of debt pay more to carry it, so profit shrinks. (We covered gearing in Ep 17.) Property companies, the REITs from Ep 13, often borrow heavily, and they also get compared with safe savings. If a bank account pays more, a property dividend looks less special, so the price can soften. And when borrowing gets dearer, households spend less, which can hurt retailers and anyone selling big-ticket items on credit.
Bull case. Banks can earn a wider gap between what they charge to lend and what they pay to borrow, which can help profits. That’s a possibility, not a rule: if borrowers struggle to repay, bad loans eat the gain. And a Reserve Bank that keeps inflation down protects what your money can buy. Runaway inflation is a tax on everyone, share owner or not.
The part most people miss: the market doesn’t wait for the hike. Prices often move before the announcement because investors are already guessing. By the time the news lands, a lot of it may already be in the price. That’s why a hike can arrive and a share barely blinks, or does the opposite of what you’d expect.
Who gets hurt and who benefits depends on the company’s debt, its customers and its margins. One headline can’t tell you that.

- The repo rate is what the Reserve Bank charges banks to borrow. Banks add a margin to set prime, which drives bond and car payments.
- On 23 September 2026 the repo rate rose 25 basis points to 7.25%, and prime went to 10.75%.
- Inflation was 4.4% in August. The target is 3%.
- On a R1 million, 20-year bond at prime, the hike adds about R168 a month.
- Higher rates squeeze borrowers and heavily indebted companies, and can help savers and some lenders.
Key numbers
- Repo rate: 7.25%, up 25 basis points. So what: the wholesale price of money just went up.
- Prime rate: 10.75%, from 10.5%. So what: the rate most bonds and car loans are priced off.
- August inflation: 4.4%. So what: inside the band, but above the 3% target.
- Extra on a R1m, 20-year bond: about R168 a month. So what: small per month, big over 20 years.
Takeaway: Repo is the wholesale price of money. Prime is what you pay. Inflation is why it moves.

Before you start reading every rate decision like a weather forecast for your portfolio, remember: this is not financial advice. I’m explaining a term, not telling you what to do with your money. Do your own research, read the actual Reserve Bank statement, and if real money is on the line, speak to a licensed advisor, not a podcast uncle with strong opinions about prime.
