June 2026 Fuel Price South Africa Update: Relief for Diesel, But Petrol Taxes Sting

If you are driving a diesel vehicle, substantial relief is on the way. If you fill up with petrol, a minor hike is still locked in—but it is far less severe than initially feared.

Here is everything you need to know about the final fuel price adjustments hitting pumps on Wednesday, 3 June 2026.

The June 2026 fuel price outlook 

According to the final month-end data provided by the Central Energy Fund (CEF) and statements from the Fuels Industry Association of South Africa, the official projected changes are as follows:

• Petrol 93: Expected increase of around R1.04 per litre.

• Petrol 95: Expected increase of around R1.08 per litre.

• Diesel 0.05% (Sulphur): Expected decrease of around R3.60 per litre.

• Diesel 0.005% (Sulphur): Expected decrease of around R2.96 per litre.

The great tug-of-war

Understanding the June fuel price requires looking at two opposing forces: a massive crash in international oil prices (the good news) and the scheduled rollback of government tax relief (the bad news).

The good news

For the bulk of May, global energy markets were in severe shock. The US-Iran conflict and the subsequent closure of the strategic Strait of Hormuz drove Brent Crude oil well past the $100-a-barrel mark.

However, a dramatic breakthrough occurred at the end of May. The US and Iran tentatively agreed to extend their ceasefire by 60 days, giving markets hope that shipping lanes would soon reopen. As a result, global oil prices tumbled down to roughly $92 a barrel—a 19% drop in a matter of days.

This market crash created a massive "over-recovery" (savings) for South African fuel imports:

• Petrol achieved an over-recovery of roughly 42 to 46 cents per litre.

• Diesel achieved an astonishing over-recovery of R4.93 to R5.57 per litre.

The bad news

In April and May, the National Treasury stepped in to shield consumers from record-high fuel prices by slashing the General Fuel Levy by R3.00/l for petrol and R3.93/l for diesel.

As announced by Minister of Finance Enoch Godongwana, this temporary emergency intervention is formally phasing out. Effective Wednesday, 3 June, 50% of that tax relief is being added back to the price of fuel.

• Petrol taxes will increase by R1.50 per litre (raising the levy from R1.10 to R2.60).

• Diesel taxes will increase by R1.97 per litre (raising the levy from R0.00 to R1.97).

Additionally, the Slate Levy—used to reimburse oil companies for cumulative under-recoveries—is being raised to approximately R1.58 per litre for both fuel types, compounding domestic regulatory pressure.

Diesel plummets while petrol rises

The contrast between petrol and diesel behaviour comes down to simple math.

For petrol, the market over-recovery of 44 cents was simply not large enough to absorb the R1.50 fuel levy increase and slate adjustments. Consequently, petrol is pushed back into the red, resulting in a net increase of just over R1.00 per litre.

For diesel, the massive market over-recovery of up to R5.57 per litre completely swallowed the R1.97 tax reintroduction. Even after the government took back its tax cut, there was plenty of international market savings left over to pass through to consumers, resulting in a spectacular net price drop at the pumps.

Looking ahead

While diesel drivers can celebrate temporary relief this winter, motorists must prepare for July. The National Treasury has confirmed that the remaining 50% of the temporary fuel levy relief will expire on 1 July 2026.

When that happens, the general fuel levy will completely return to its baseline rates of R4.10 per litre for petrol and R3.93 per litre for diesel. Unless global oil prices continue to drop aggressively throughout June, July is highly likely to bring another heavy tax-driven hike to South African pumps.
