JOHANNESBURG, Gauteng — Motorists across the country are bracing for a major South Africa fuel price increase effective from midnight, as diesel surges by more than R3 per litre and petrol rises by R1.34. This latest adjustment reverses the brief relief seen in July and August, pushing some diesel grades above the R30 mark due to a combination of global supply pressures and domestic cost factors.

The fuel price trajectory in 2026 has been characterized by sharp swings. After starting the year with cheaper fuel, prices surged mid-year before offering temporary relief. However, the ongoing conflict in Iran continues to impact global oil prices, reversing recent gains and ensuring consumers will feel the financial strain of escalating petrol and diesel costs.

For inland 95 petrol, the price was R20.75 per litre at the start of the year before jumping to R28.06 by June. Following a brief dip in July and August, September sees a rise of R1.34, bringing the price to R26.92 per litre. While the South African rand strengthened against the US dollar this month, providing marginal relief, it was insufficient to offset the broader surge in international oil and refined product prices.

Brent crude, the global oil benchmark, climbed from an average of approximately $82 to nearly $88 per barrel. Diesel has been hit particularly hard by these global shifts. Under-recoveries for 0.05% sulfuric diesel currently sit at 271, while the cleaner 0.005% sulfuric content diesel faces an under-recovery of 292. Consequently, the official benchmark price for 0.05% sulfa diesel is rising by almost R2.94 per litre, and the lower sulfur grade is increasing by more than R3.14 per litre. This extreme increase is largely attributed to tighter global refining capacity and ongoing supply pressures.

According to the Department of Petroleum Resources, international oil and refined-product prices remain the primary drivers of this month’s hike, though domestic costs are also factored into the increase. The department’s insights highlight a structural vulnerability: because South Africa has lost much of its domestic refining capacity, the country now procures a large portion of its petrol and diesel from overseas. Had the nation retained its refineries, it would have been shielded from some of these elevated global price increases by relying on local refining costs and capacity.

The more than R3 increase in diesel extends far beyond the fuel station. Because diesel powers trucks, farms, construction sites, mines, and the broader logistics network, higher fuel costs create a direct risk of more expensive freight. This, in turn, places additional upward pressure on the prices of food and essential goods across the country.

Domestic adjustments are also contributing to the monthly increase. The government’s slate levy is rising by more than 21 cents to 83 cents per litre, a mechanism used to recover accumulated under-recoveries within the fuel pricing system. Additionally, petrol prices include a 4.9-cent per litre adjustment linked to the annual wage increase for court workers.

For motorists, these compounded increases represent another severe squeeze on already stretched household budgets. As the market absorbs these changes, the critical question remains whether this September adjustment is merely another bump in a volatile year or the beginning of a sustained period of higher fuel prices in South Africa.
