South African motorists may need to brace for a rise in fuel prices this September, as suggested by the latest data from the Central Energy Fund (CEF). The anticipated price adjustments could see petrol costs increasing by about 83 cents per litre for 93 octane and 94 cents for 95 octane. Diesel prices are projected to face even steeper hikes, with potential increases of R2.87 per litre for 0.05% diesel and R3.07 per litre for 0.005% diesel. Additionally, the cost of illuminating paraffin might go up by approximately R2.24 per litre.
Particularly concerning is the potential rise in diesel prices, as diesel is integral to several key sectors including freight, agriculture, construction, and mining. A significant hike in diesel costs could translate into higher transportation and operational expenses, thereby exerting upward pressure on food and consumer prices.
Although the outlook has improved since earlier in August—when petrol was expected to rise by around R1 per litre and diesel by nearly R5 per litre—the current figures still indicate a substantial upward pressure on fuel costs. The dynamics of international oil prices and the rand-dollar exchange rate continue to be crucial factors affecting South Africa’s monthly fuel price adjustments.
Despite the rand showing some resilience, offering a degree of relief, elevated international petroleum prices are still contributing to fuel under-recoveries. It is important to note that the CEF figures are preliminary and could change before the final adjustments are announced. The revised fuel prices are scheduled to take effect starting 1 September 2026.
