December Fuel Price Forecast: 5 Important Things South African Drivers Need to Know
December 2026 fuel price forecasts point to cheaper petrol but potentially higher diesel prices. See what South African motorists should expect.
South African motorists could receive some relief at the petrol pumps in December 2026, but diesel users may face another increase. Early fuel-price calculations suggest that petrol prices could fall while diesel prices move in the opposite direction. The latest projections come as households prepare for the festive season, when millions of South Africans travel to visit family, attend events and take holidays.
However, motorists should not treat the projected figures as confirmed prices. The Department of Mineral and Petroleum Resources (DMPR) will announce the official December adjustments closer to the next price-change date. Here are five important things drivers should understand about the December fuel price forecast.
1. December petrol prices could decrease
The latest Central Energy Fund (CEF) figures point towards lower petrol prices in December. A report published by CAR Magazine on 11 November estimated that 93 petrol could decrease by approximately R1.52 per litre, while 95 petrol could fall by around R1.82 per litre. These figures are projections, not official government prices.
The outlook offers some encouragement to motorists after petrol prices crossed R30 per litre in Gauteng during October. From 4 November, inland motorists paid R29.87 per litre for 93 petrol and R30.24 for 95 petrol. If the projected reductions materialise, drivers could see a noticeable difference when filling their vehicles. However, international oil prices, the rand-dollar exchange rate and government fuel levies can still change the final calculation before December’s announcement. CAR Magazine+1
2. Diesel drivers could face another increase
The December outlook is less encouraging for diesel users. CAR Magazine’s report indicated that diesel prices could increase by approximately R1.49 per litre for 0.05% sulphur diesel and R1.15 for 0.005% sulphur diesel. This could create additional pressure for transport operators, delivery businesses, farmers and companies that depend heavily on diesel-powered vehicles and machinery.
Diesel also plays an important role in moving goods across South Africa. If transport companies experience higher fuel expenses, businesses could face additional operating costs. Some may eventually pass part of those expenses on to customers through higher delivery charges or product prices.
It is important to remember that diesel prices are not regulated at the pump in the same way as petrol. The government publishes wholesale prices, while individual retailers determine their selling prices. The final December adjustment could still differ from current projections. CAR Magazine+2
3. The temporary fuel levy relief is changing
One of the biggest factors affecting December’s fuel prices is the temporary fuel levy relief announced by Finance Minister Enoch Godongwana. The government introduced reductions to help households and businesses manage rising fuel costs. From 4 November, the general fuel levy reduction amounted to R1.50 per litre for petrol and R3 per litre for diesel. However, the relief is scheduled to become smaller from December.
According to the published projections, the petrol reduction will fall from R1.50 to R1 per litre, while diesel relief will decrease from R3 to R1.50 per litre. That means 50 cents per litre of petrol relief and R1.50 per litre of diesel relief will fall away. This matters because even when international fuel costs improve, a reduction in government relief can offset some of the savings motorists might otherwise receive. The final price will depend on how these levy changes combine with movements in international petroleum prices and the rand. CAR Magazine+2
4. International oil prices and the rand remain important
South Africa imports crude oil and finished petroleum products, making local fuel prices sensitive to developments in international markets. Two major factors influence the monthly calculation: global oil prices and the exchange rate.
When international oil prices rise, importing fuel generally becomes more expensive. A weaker rand can make those imports even more costly because South Africa needs more local currency to purchase products priced in US dollars. The opposite can also happen.
Lower international oil prices and a stronger rand can help reduce the cost of importing petroleum products. The DMPR’s November announcement highlighted how expensive crude oil, higher international product prices and a weaker rand contributed to pressure on the fuel-price structure.
The department reported that average Brent crude increased from US$101 to US$108 per barrel during the period used for that adjustment. Although the December outlook has improved for petrol, motorists should remember that international conditions can change before the next official announcement. South African Government+1
5. When will South Africans know the official December prices?
The next monthly fuel-price adjustment is expected to take effect on Wednesday, 2 December 2026. The government normally announces the new prices shortly before implementation. Until then, motorists should treat all December figures as estimates rather than confirmed pump prices.
The CEF updates its fuel-price information during the review period, meaning projections can move as new international oil prices and exchange-rate figures become available. Drivers planning festive-season trips should therefore avoid relying entirely on early forecasts when preparing their budgets.
Checking the official announcement closer to the adjustment date will provide a clearer picture of what motorists will actually pay. The DMPR publishes official fuel-price information through its website, while the CEF provides the underlying daily calculations used to assess possible changes. OilPrices.co.za+2
What the December fuel forecast means for households
December could bring welcome relief for petrol motorists, but diesel users may have a different experience. The smaller fuel levy relief also means that any improvement in international prices will not necessarily translate into an equally large reduction at the pumps.
For families planning festive-season travel, even a modest reduction could help manage transport expenses. Businesses that rely on diesel will need to watch the final announcement carefully. The biggest question now is whether the latest projections will hold until the end of November.
