South African drivers might be bracing for another hike in fuel prices this September, as the latest data from the Central Energy Fund (CEF) suggests increases across petrol, diesel, and illuminating paraffin. The anticipated adjustments could see 93 petrol rise by approximately 83 cents per litre, while 95 petrol may go up by 94 cents. Diesel prices are set for a steeper climb, with projections indicating a rise of about R2.87 per litre for 0.05% diesel and R3.07 for 0.005% diesel. Additionally, illuminating paraffin might increase by around R2.24 per litre.
The potential surge in diesel costs is particularly concerning, given its extensive use in various sectors such as freight, agriculture, construction, and mining. A significant rise in diesel prices could lead to heightened transportation and operational costs, which may subsequently affect food and consumer prices, adding economic pressure.
This outlook marks an improvement from earlier in August when predictions suggested a possible increase of around R1 per litre for petrol and nearly R5 per litre for diesel. Despite this slightly more optimistic scenario, the latest figures underscore that fuel costs remain under notable upward pressure.
Monthly fuel-price adjustments in South Africa are primarily influenced by international oil prices and the rand-dollar exchange rate. Although the rand has shown some resilience, offering a degree of relief, elevated global petroleum prices continue to play a significant role in fuel under-recoveries.
The figures provided by the CEF are preliminary and subject to change before the final adjustments are announced. The updated fuel prices are expected to be implemented starting September 1, 2026.
