South African consumers are bracing for a potential interest rate increase and a petrol price that analysts warn could breach R30 per litre by mid-year, as Middle East oil market instability drives up fuel costs and forces the South African Reserve Bank to reconsider rate cuts it had been expected to implement in 2026.
The repo rate currently sits at 6.75%, where the Monetary Policy Committee held it at its March 2026 meeting.
However, SARB Governor Lesetja Kganyago has made clear that the central bank is watching oil-price-driven inflation closely and will not hesitate to respond if second-round effects begin to materialise.
Kganyago warns against complacency on inflation
Speaking after the March MPC decision, Governor Kganyago struck a notably hawkish tone, warning that the bank would not allow inflation to embed itself even if its immediate cause was an external shock. “We are not going to try and be pre-emptive,” Kganyago said.
“But neither can we afford to be complacent and say we’ve got to wait for the second-round effects to arrive before we actually take an appropriate policy response.”
Kganyago reiterated the SARB’s mandate with precision.
“For us as a central bank, our function is to make sure that the impact of the shock is only transient and not persistent,” he said.
Forward-rate agreements, which reflect market expectations for interest rates, are now pricing in three potential rate hikes by early 2027.
That is a sharp reversal from the trajectory of a few months ago, when the consensus expected the MPC to cut rates at least once in the first half of 2026.
Petrol price could exceed R30 per litre by mid-year
The immediate pain for motorists is already real. The April 2026 fuel price adjustment included a hike of approximately R3 per litre for 95-octane petrol and R7 per litre for diesel, though the government absorbed part of the impact by reducing the fuel levy at a cost of roughly R6 billion to the Treasury. Without that intervention, the increases would have been materially higher.
At current international crude oil prices, which climbed from below $60 a barrel earlier in 2026 to above $100 on the back of escalating Middle East conflict, analysts project that the 95-octane petrol price could exceed R30 per litre by June or July if conditions do not improve.
A 60-litre fill of 95-octane petrol currently costs motorists approximately R1 560, and a R30/litre price point would push that to R1 800 per tank.
The next petrol price announcement from the Department of Mineral and Petroleum Resources is expected in late April for implementation on 7 May 2026.
Consumers and transport operators are advised to monitor the department’s mid-month data release for an early indication of the adjustment direction.
What this means for household budgets
Rising fuel prices do not remain at the pump. They feed through into food prices, transport costs and virtually every sector of the consumer economy.
The combination of elevated interest rates, meaning higher bond repayments and credit costs, alongside accelerating fuel and food inflation is placing household budgets under severe pressure.
Financial advisers are urging South Africans to review bond repayment buffers and discretionary spending ahead of any potential MPC rate decision.
The next scheduled MPC announcement is due on 22 May 2026.
