South African motorists have a narrow window to visit the pumps before a significant spike in fuel costs takes effect at midnight. The Department of Petroleum and Mineral Resources has announced a series of sharp price adjustments that will hit petrol and diesel users starting Wednesday, creating an immediate incentive for drivers to fill their tanks before the clock runs out.
The price hikes are not uniform, with diesel users facing the steepest increases. While petrol prices are rising significantly, the cost of diesel—the lifeblood of the country’s logistics and transport sectors—is seeing a much more aggressive jump. This divergence reflects a volatile global market where specific types of refined fuel are under more pressure than others.
These adjustments come amid a period of intense geopolitical instability. According to government data, the primary driver is a surge in the cost of Brent Crude, which has climbed from $93.67 to $101 per barrel. The increase is tied directly to escalating tensions between the U.S. And Iran, compounded by the closure of the Strait of Hormuz and targeted damage to critical supply infrastructure in the Persian Gulf.
Breaking down the cost at the pump
For the average commuter, the impact will be felt immediately. Both 93 and 95 octane petrol (ULP and LRP) will increase by R3.27 per litre. However, those relying on diesel will see a much sharper hit to their wallets, with prices for both 0.05% and 0.005% sulphur grades increasing by R5.27 per litre.
The price volatility extends beyond the commute. Households relying on illuminating paraffin will see wholesale prices rise by R4.22 per litre and retail prices by R5.63 per litre. Liquefied Petroleum Gas (LPGas) is also climbing, with the maximum retail price increasing by R5.07 per kilogram in Gauteng, and R5.78 per kilogram in the Western Cape.
| Fuel Type | Price Increase (per Litre/Kg) |
|---|---|
| Petrol (93 & 95 Octane) | + R3.27 / L |
| Diesel (All Grades) | + R5.27 / L |
| Paraffin (Retail) | + R5.63 / L |
| LPGas (Gauteng) | + R5.07 / kg |
| LPGas (Western Cape) | + R5.78 / kg |
The economics of the ‘Middle Distillate’ crunch
From a market perspective, the disparity between the petrol and diesel hikes is the most telling detail. In the energy sector, diesel and paraffin are classified as “middle distillates.” Unlike crude oil or gasoline, these products are more sensitive to specific refinery capacities and regional supply disruptions.
The closure of the Strait of Hormuz—a narrow waterway that carries roughly one-fifth of the world’s total oil consumption—has created a bottleneck. While the South African Rand has remained relatively stable against the U.S. Dollar, preventing a currency-driven price spiral, the sheer lack of available middle distillates coming out of the Persian Gulf has pushed prices higher for diesel and paraffin than for petrol.
Adding to the cost is a “slate levy” of 122.70 cents per litre. This is a technical recovery mechanism used by the government to address a negative balance in the fuel fund. At the end of March, this balance stood at a massive R14.173 billion; the levy is designed to recoup those losses to ensure the long-term stability of the fuel pricing structure.
Government intervention and temporary relief
To prevent these global shocks from triggering a domestic economic crisis, the Minister of Finance and the Minister of Mineral and Petroleum Resources have implemented a temporary cushion. The government is extending a short-term relief measure by reducing the general fuel levy.
Starting May 6, 2026, and running through June 2, 2026, the general fuel levy will be reduced by 300.0 c/l for petrol and 393.0 c/l for diesel. While this does not erase the price hike, it significantly lowers the “ceiling” of what consumers would otherwise be paying if the full international price and the slate levy were applied without mitigation.
“Due to the ongoing US-Iran conflict which continues to affect fuel prices globally, the Minister of Finance in consultation with the Minister of Mineral and Petroleum Resources announced a further temporary reduction in the general fuel levy,” the Department of Mineral and Petroleum Resources stated.
Who is most affected?
- Logistics and Freight: With diesel rising by over R5 per litre, trucking companies and delivery services will likely face increased operational costs, which often trickle down to consumer goods prices.
- Low-Income Households: The rise in paraffin and LPGas prices disproportionately affects households that rely on these fuels for heating and cooking.
- Daily Commuters: The R3.27 petrol hike adds a noticeable monthly burden to the average vehicle owner, particularly those with longer commutes.

The current relief measures provide a temporary reprieve, but the outlook remains tied to the volatility in the Persian Gulf. All eyes now turn to the June 2, 2026, deadline, when the current temporary levy reductions are scheduled to expire. Whether the government will extend these measures further will depend on the resolution of the conflict between the U.S. And Iran and the reopening of critical shipping lanes.
