Will the repo rate go up in September 2026?

Nobody knows yet — the SARB's Monetary Policy Committee announces on Wednesday 2026-09-23. bond.co.za's read of the verified data: repo sits at 7.00% and prime at 10.50% after May's 25bp hike, October's petrol price is tracking above R29/litre on mid-month CEF data, and Q2 GDP contracted 0.2% — inflation and growth risks pulling in opposite directions.

What is the expected repo rate for South Africa in 2026?

The repo rate stands at 7.00% and prime at 10.50% (SARB, re-verified 2026-09-12). The MPC raised the rate by 25 basis points on 28 May 2026 — the first change since May 2023 — and then held on 23 July by a narrow 4-2 vote, with the July statement citing oil and food-price risks from the Middle East conflict as upside risks to inflation. What happens next is decided on Wednesday 2026-09-23. bond.co.za does not make rate predictions; for how analysts frame the likely path, see bond.co.za's interest rate forecast explainer, and for the current benchmark itself, today's prime rate page.

Why is the petrol price a risk to the repo rate?

Petrol feeds straight into headline inflation through transport costs, and October's increase is shaping up as a record. Central Energy Fund mid-month recovery data, as reported by IOL and BusinessTech in September 2026, points to an increase of more than R2 a litre across grades, which would take 95 ULP above R29 a litre for the first time — driven by Brent crude trading around $108 a barrel amid the ongoing Middle East conflict. The July MPC statement explicitly named oil-price risks when four of six members still chose to hold. A fuel shock of this size arriving days before the announcement is the single strongest argument for another increase.

CEF mid-month figures are unaudited and move daily; the final October adjustment is set by the Department of Mineral Resources and Energy in the first week of October 2026. Treat the R29 tracking as a projection, not a settled price.

Does the GDP contraction argue for a repo rate cut?

It argues against hiking, at least. Stats SA's Q2 2026 GDP release shows the economy contracted 0.2% quarter-on-quarter after growing 0.4% in Q1, with mining, manufacturing and trade the main drags, and the unemployment rate at 33.6% (Stats SA QLFS, Q2 2026). Raising borrowing costs into a stalled economy risks deepening the slowdown. That leaves the MPC facing a genuine tension on 2026-09-23: an inflation shock arriving on top of a contraction — which is precisely why the outcome is genuinely uncertain rather than a foregone conclusion.

What happens when the repo rate increases?

South African banks price variable-rate home loans off prime, which sits at repo + 3.5 percentage points — so a 25 basis point repo increase takes prime from 10.50% to 10.75%, and the instalment on every variable-rate bond reprices with it. bond.co.za's companion piece works through exactly what a 25bp hike adds to bonds of R500,000 to R2.5 million, and the rate-change repayment table shows the same maths per bond size. If you are house-hunting now, run your target instalment through the rate increase impact calculator before the decision rather than after it.
