The May 2026 fuel price forecast signals the largest pump increases in recent memory, driven by Middle East conflict, a weakened rand, and the expiry of government levy relief — with new prices locked in from midnight, 5 May.

A Forecast That Is Hitting Home
South Africa’s May 2026 fuel price forecast has become one of the most watched economic stories of the year — and with good reason.
Central Energy Fund (CEF) data confirms that motorists will face significant increases across petrol, diesel, and illuminating paraffin when new prices take effect at midnight on Tuesday, 5 May 2026.
The May 2026 fuel price forecast is not a worst-case scenario — it is the base case. Under-recoveries have been accumulating since March, when global oil prices surged past $100 per barrel and a US-Iran military standoff threatened to choke off the Strait of Hormuz, a narrow corridor responsible for roughly one-fifth of all global oil and gas trade.
For South African consumers, businesses, and the logistics sector, the implications extend well beyond the pump.
What Is Driving the May Surge
- The Strait of Hormuz Crisis
The primary catalyst behind the current fuel price environment is the ongoing disruption in the Strait of Hormuz.
Following the collapse of US-Iran talks in Islamabad, the United States Armed Forces enforced a naval blockade affecting Iranian-linked shipping through the corridor.
Some tankers have diverted entirely, opting for the longer Cape of Good Hope route — adding fuel consumption, transit time, and surging insurance premiums to every barrel of crude shipped westward.
Brent crude climbed above $110 per barrel in April and analysts warn prices could push as high as $120 to $125 per barrel if negotiations remain deadlocked.
Even partial disruptions have historically been enough to sustain elevated price floors across global energy markets.
- The Rand-Dollar Exchange Rate
South Africa’s fuel import costs are denominated in US dollars, making the rand-dollar rate a secondary but significant pressure point.
The rand has stabilised at around R16.30 to R16.64 per dollar — relatively contained given global risk-off sentiment — but its contribution to pump price pressure remains an estimated R1 per litre.
Currency volatility in the final days of April could still shift the final adjustment.
- The Expiry of Levy Relief
The government’s emergency R3.00 per litre General Fuel Levy reduction, introduced on 1 April 2026, is scheduled to expire on 5 May.
Finance Minister Enoch Godongwana extended the measure — including an enhanced diesel levy relief of R3.93 per litre, effectively zeroing out diesel’s General Fuel Levy for May — but has signalled clearly that it cannot continue indefinitely.
The total fiscal cost of maintaining relief from April through June is estimated at R17.2 billion.
Without the levy cushion, the increases South Africans would have faced in May were projected to be catastrophic: early-April CEF data showed under-recoveries as high as 518 cents per litre for petrol 93 and more than R14 per litre for diesel.
The extended relief has brought those numbers down substantially, but the underlying market pressure has not resolved.
The Numbers: What Motorists Will Pay
Based on the latest CEF data as of 30 April 2026, the following increases are projected for the May 2026 adjustment:
- Petrol 93 Unleaded: increase of approximately 173 cents per litre
- Petrol 95 Unleaded: increase of approximately 204 cents per litre — coast price expected around R24.38/litre
- Diesel (0.05%): increase of approximately 496 to 497 cents per litre
- Illuminating Paraffin: increase of approximately 422 cents per litre
These figures reflect the blended effect of the under-recovery and the continued levy relief.
The final official numbers will be confirmed by the Department of Mineral and Petroleum Resources (DMRE) ahead of the midnight price change on 5 May.
Beyond the Pump: Economic Ripple Effects
Investec Chief Economist Annabel Bishop has described the May 2026 fuel price forecast as an inflation event, not merely a motoring inconvenience.
The projected increases are expected to add 0.6 percentage points to the monthly Consumer Price Index, potentially lifting May CPI to 4.2% — well above the 3.7% baseline forecast.
This could pressure the South African Reserve Bank (SARB) toward a 25-basis-point interest rate hike at its 28 May Monetary Policy Committee meeting.
The downstream effects are already being mapped. Diesel — the fuel that powers logistics, agriculture, construction, and freight — sees the steepest increases.
Higher diesel costs push up the cost of moving goods, which then flows into retail prices, food inflation, and general manufacturing input costs.
The Fuels Industry Association of South Africa warned of a rush to fill up before the 5 May price change, placing pressure on supply infrastructure at key distribution points.
For the construction and heavy equipment sector, diesel-dependent plant operations face a material cost increase from 6 May.
Equipment rental companies, earthmoving contractors, and mining operations running large fleets will need to revise operating budgets and consider passing costs to clients through contract fuel clauses.
The Relief Roadmap: A Narrowing Window
The government’s levy relief programme will begin to unwind in the coming months, creating a compounding risk for fuel costs regardless of what happens in global oil markets:
- May 2026: Diesel levy relief at R3.93/litre (General Fuel Levy effectively zero for diesel)
- June 2026: Petrol relief reduced to R1.50/litre; diesel relief cut to R1.96/litre
- July 2026: All relief removed — full levies reinstated
This means that even if Brent crude stabilises and the rand holds, South Africans will face another structural baseline increase in July when the levy cushion disappears entirely.
Policymakers are reportedly exploring longer-term fuel pricing reforms, but no concrete mechanism has been announced.
Outlook: The May 2026 Fuel Price Forecast Remains Fluid
The May 2026 fuel price forecast has already shifted dramatically from the doomsday figures circulated in early April, when some analysts projected diesel increases of R10 per litre or more.
A partial ceasefire announcement in mid-April briefly pushed Brent below $94 per barrel before markets reasserted the uncertainty premium. Prices have since climbed back above $110.
The two decisive variables for the final adjustment remain global oil prices and any last-minute government policy action on levies.
Markets will be watching closely for any diplomatic movement on the Strait of Hormuz and any shifts in the rand-dollar rate through the final trading days of April.
For now, the message for South African households, logistics operators, and heavy industry is consistent: the relief programme has bought time, but it has not resolved the underlying structural pressure.
Elevated fuel costs look set to remain a defining feature of the South African cost environment through at least the third quarter of 2026.
