South Africa's temporary R3 per litre fuel levy cut runs out at midnight on May 5, 2026. If Treasury does not extend it, the next price update on May 6 could push diesel up by more than R7 a litre. Shop owners, taxi operators, and anyone who pays for delivery trips need to plan now.

What the R3 levy cut did

On March 31, 2026, Finance Minister Enoch Godongwana cut the General Fuel Levy by R3 a litre on both petrol and diesel. The cut runs from April 1 to May 5, 2026.

According to BusinessDay SA, the petrol levy fell from R4.10 to R1.10 and the diesel levy fell from R3.93 to R0.93. The Road Accident Fund levy and the carbon fuel levy were not changed.

The cut was a direct response to the Strait of Hormuz oil supply shock that started on February 28, 2026. Without it, Treasury said petrol would have risen by R5.81 a litre in April and wholesale diesel by R10.27. The cut held the actual increases to about R3.06 for petrol and R7.51 for diesel.

The DA's finance spokesperson Mark Burke told Eyewitness News that the relief is costing Treasury about R6 billion in lost tax revenue.

What May fuel prices could look like

The Department of Mineral Resources and Energy will announce final May 2026 prices on May 6, 2026. The new prices take effect at midnight that night.

Forecasters are using mid-month Central Energy Fund (CEF) data to estimate the move. As of April 21, 2026, CEF data reported by The South African pointed to these projected changes:

Fuel	Projected change (May 2026)
Petrol 93	+R2.02 a litre
Petrol 95	+R2.36 a litre
Diesel 0.05%	+R7.07 a litre
Diesel 0.005%	+R7.09 a litre
Illuminating Paraffin	+R5.81 a litre

These are projections, not final prices. They assume Brent crude near $94 a barrel and the rand near R16.39 to the dollar. They also assume the R3 levy cut is not extended.

If Treasury does extend the levy cut into May, the increases above would shrink by roughly R3 a litre. Diesel would still rise. But the jump would be in the R4 range, not over R7.

The R3 cut is the difference between a tough month and an emergency month for diesel-heavy businesses.

The extension question

As of late April 2026, Treasury has not said whether the cut will be extended. IOL reported on April 21 that the relief was always meant to be a single-month measure, with a review at month-end.

Burke and the DA have called for a two-month extension, suggesting it could be funded from SETA balances and the Compensation Fund surplus. But that is a proposal, not a Treasury decision.

Cosatu and Business Leadership South Africa pushed for the original cut. They are likely to push again. Treasury has signalled that any extension is part of a broader phase 2 relief package, which has not been published.

The decision is expected close to the May 6 announcement. Plan for the worst case until you see the official notice.

What this costs your shop

Delivery and transport

If your supplier delivers in a diesel truck, expect them to pass on a fuel surcharge in the first week of May. Most logistics firms revise rates monthly. A R7 jump on diesel feeds into bread, maize meal, milk, and packaged goods within four to eight weeks.

If you do your own pickups in a bakkie, your fuel bill could rise about 17% on diesel and 4% on petrol from May 6.

Generators and backup power

Spaza shops, taverns, and small grocers running diesel generators during outages will feel this hardest. A small 5kVA generator burns roughly 1.5 litres per hour. An R7 jump means about R10.50 more per running hour.

Stock that travels far

Goods trucked from Gauteng to the Eastern Cape, KwaZulu-Natal coastal towns, or rural Limpopo will carry a higher freight cost. Wholesale prices on bulk staples often move within two weeks of a diesel hike.

Customers with less to spend

Petrol is also up. People driving to work or paying taxi fares have less cash for groceries, airtime, and small purchases. Watch for slower trading days in the second half of May.

Five things to do this week

Top up your fuel and stock now. If you have a generator, fill the tank before May 5. If you buy stock weekly, consider doing a slightly larger run before the May price update.
Talk to your supplier. Ask if their May price list is locked in, and whether a fuel surcharge is coming. Get it in writing if you can.
Reprice slow-moving stock first. Do not raise prices on fast-moving staples like bread and milk yet. Customers notice. Adjust margins on items with low turnover where the change is less visible.
Check if you qualify for the Diesel Refund Scheme. If you are in farming, fishing, or small-scale generation, SARS refunds part of the diesel levy. Read the SARS Diesel Refund page to see if you can register.
Watch for the May 6 announcement. The Department of Mineral Resources and Energy publishes final prices the morning of May 6. Adjust your delivery and pricing plans the same day.

Why This Matters

South Africa moves about 80% of its goods by road. When diesel jumps, the cost reaches every shelf in every shop within weeks. Small businesses do not have the buffer that large retailers have, so they feel the squeeze first. The R3 levy cut bought one month of breathing room. Whether it gets a second month is now a real question for shop owners, vendors, and anyone running a delivery business.

This is also a pan-African signal. Ghana, Kenya, Tanzania, and Namibia have all raised fuel prices in the past month due to the same Middle East shock. South Africa's response shows that governments can use levy cuts to soften the blow. But these cuts are short-term. The underlying oil price is still the bigger story.

Conclusion

The R3 fuel levy cut ends on May 5, 2026. Without an extension, diesel could rise by more than R7 a litre on May 6. Plan your stock runs, talk to suppliers, and watch the Treasury announcement. A few small moves this week could save real money next month.
