South Africa's central bank warns the fuel shock could spill into wages
In its Monetary Policy Review published on 6 October, the South African Reserve Bank (SARB) said the risk of the fuel shock spreading to wages and corporate costs was growing. Markets are pricing two further 25 basis-point rises within six months.
According to Sunday World on 6 October, the SARB expects 2026 inflation to average 4.4% and growth to come in at 1.2%. Inflation has risen from about 3% at the start of the year to above 4%. The bank identified second-round effects as the main threat, meaning higher fuel costs passing into wages, company expenses and inflation expectations. The report notes that the policy rate has risen by a cumulative 50 basis points since April to 7.25%. The SARB's September Monetary Policy Committee statement says the latest 25 basis-point rise was unanimous, and the next meeting is on 19 November.
The warning came a day before the 7 October pump price increase. According to BusinessDay, 95-octane petrol rises by 3.33 rand a litre from 7 October to 30.25 rand in Gauteng, while diesel goes up by 2.84 rand. The same report says petrol has risen by about 50% since March and the wholesale cost of diesel by 72%. Over the review period Brent climbed from $87.89 to $101. The trade union federation Cosatu points out that workers spend up to 30% of their wages on transport.
In its September statement the SARB had flagged an average under-recovery of 2.83 rand a litre on petrol. That meant the regulated pump price sat below cost, foreshadowing the October increase. The 6 October review lists a prolonged Middle East conflict, high refining margins, a possible El Niño and rand depreciation as further upside risks. The bank expects inflation to return to its 3% target towards the end of 2027.
Talay assessment
Bottom line
The SARB is saying plainly that it will not look through the fuel shock as a temporary supply shock; its priority is to stop inflation expectations drifting away from the 3% target. If the 7 October increase feeds into wage and pricing behaviour, another hike at the 19 November meeting is a strong possibility. The cost is a further weakening of growth expectations already stuck at 1.2%.
Likely effects
- South African ratesUncertainWeeks
Tightening expectations keep near-term rates elevated; the front end of the yield curve stays sensitive to every fuel price adjustment and inflation print.
- HouseholdsNegativeWeeks
The fuel increase and a possible rate rise squeeze disposable income at the same time; workers spending up to 30% of income on transport are hit hardest.
- Energy-importer central banksUncertain1–6 months
The SARB's stance strengthens the tendency among oil-importing emerging economies to answer fuel shocks with rates; the same second-round risk applies to them, Türkiye included.
Possibilities, ranked
- 1November hike55%
October inflation reflects the fuel increase and the SARB raises rates by a further 25 basis points on 19 November.
Watch: October CPI data and the 19 November MPC decision
- 2Hold with a warning35%
Core inflation and wages do not confirm second-round effects; the SARB holds at 7.25% and keeps a hawkish tone.
Watch: Core inflation and new collective wage agreements
- 3A bigger step10%
If Brent keeps rising and the rand keeps weakening, the SARB opts for a rise larger than 25 basis points.
