How to Check June 2026 Diesel Price Forecast
South African motorists and businesses are closely watching the June 2026 diesel price forecast as fuel costs continue to affect transport, food prices, farming, and household budgets. After months of sharp increases, diesel users are finally expected to get some relief, with forecasts showing possible cuts of more than R2 per litre after levy adjustments.
At the same time, petrol prices are still expected to rise because the government is reducing temporary fuel levy relief. Understanding how to check the diesel price forecast correctly can help drivers, logistics companies, and households plan fuel spending early and avoid surprises when official prices are announced.

June 2026 Diesel Price Forecast Overview
The latest projections from the Central Energy Fund (CEF) show significant diesel price decreases for June 2026. These estimates are based on international oil prices, fuel import costs, and the rand-to-dollar exchange rate.
Expected Diesel Price Changes
| Fuel Type | Current Price | Expected June Price | Estimated Change |
|---|---|---|---|
| Diesel 0.05% | R31.17/litre | R28.73/litre | −R2.44 |
| Diesel 0.005% | R31.88/litre | R30.33/litre | −R1.55 |
| Illuminating Paraffin | R28.43/litre | R24.06/litre | −R4.37 |
These forecasts may still change slightly before the Department of Mineral and Petroleum Resources announces the official prices at the end of May 2026.
Why Diesel Prices Are Falling in June 2026
Diesel prices are expected to decrease mainly because global fuel markets have become more stable after heavy volatility earlier in the year. International diesel product prices have softened compared to April and May.
Several important factors are helping diesel prices move lower:
- Lower international diesel recovery prices
- Improved stability in crude oil markets
- A relatively stable rand exchange rate near R16.50–R16.64/$
- Reduced pressure in global fuel supply chains
- Slower fuel demand growth in some international markets
These combined factors are creating temporary relief for diesel users across South Africa.
Why Petrol Prices Are Still Increasing
Although diesel is expected to become cheaper, petrol users may still face higher pump prices in June 2026. The main reason is the government’s fuel levy relief rollback.
The temporary levy relief introduced earlier in 2026 is now being reduced by half. This change removes part of the subsidy motorists previously received, which directly increases petrol prices.
Fuel Levy Relief Changes
| Fuel Type | Previous Relief | June 2026 Relief |
|---|---|---|
| Petrol | R3.00/litre | R1.50/litre |
| Diesel | R3.93/litre | R1.96/litre |
Because of this adjustment, inland petrol prices may increase by around R1.63 to R1.69 per litre despite smaller underlying fuel price movements.
How to Check the June 2026 Diesel Price Forecast
Checking fuel price forecasts is simple if you use reliable sources. South Africa updates unofficial projections several times before the final monthly fuel price announcement.
Best Sources to Check Fuel Forecasts
- Central Energy Fund (CEF) fuel snapshot reports
- Department of Mineral and Petroleum Resources updates
- Major South African news websites
- Automobile associations and transport industry reports
- Fuel retailer market updates
It is important to compare multiple trusted sources because projections can change daily depending on oil prices and currency movements.
What Information You Should Monitor
When checking forecasts, pay attention to:
- Diesel 0.05% and Diesel 0.005% price estimates
- Inland versus coastal fuel prices
- Fuel levy adjustments
- Brent crude oil prices
- Rand/dollar exchange rate movements
- Official government announcement dates
Tracking these details gives a more accurate understanding of expected pump prices.
Difference Between Inland and Coastal Diesel Prices
Fuel prices in South Africa are not identical across all regions. Inland areas usually pay more because transportation and distribution costs are higher.
Current May 2026 Diesel Prices
| Region | Diesel 0.05% | Diesel 0.005% |
|---|---|---|
| Inland | R32.09 | R32.30 |
| Coastal | R31.26 | R31.54 |
Coastal areas generally benefit from lower logistics costs because imported fuel enters through ports closer to distribution centers.
When Official June 2026 Fuel Prices Will Be Announced
The Department of Mineral and Petroleum Resources normally confirms official fuel price adjustments during the final week of each month.
For June 2026, the official announcement is expected near the end of May, while the new fuel prices are likely to take effect during the first week of June.
Motorists should remember that forecasts are unofficial until the department publishes final confirmed prices.
How Diesel Price Changes Affect South Africans
Diesel prices influence far more than transport costs. Lower diesel prices can reduce pressure across several sectors of the economy because many industries depend heavily on diesel-powered vehicles and machinery.
- Trucking and freight companies
- Farmers and agricultural businesses
- Public transport operators
- Construction companies
- Delivery and logistics services
- Small businesses using generators
Lower diesel costs may also help slow increases in food and transport prices over time.
Common Mistakes People Make When Checking Fuel Forecasts
Many motorists misunderstand how fuel forecasts work and often expect projections to remain fixed until implementation day.
- Treating early forecasts as final official prices
- Ignoring fuel levy adjustments
- Only tracking crude oil prices
- Forgetting the impact of the rand exchange rate
- Comparing inland and coastal prices incorrectly
Fuel forecasts can change daily, especially when global oil markets become volatile.

Expert Tips for Managing Fuel Costs in June 2026
Even with expected diesel relief, fuel prices remain historically high. Smart budgeting and fuel-saving habits can still make a meaningful difference.
- Refill before official price increases take effect
- Maintain proper tyre pressure
- Avoid aggressive acceleration
- Reduce unnecessary vehicle weight
- Combine trips to save fuel
- Service diesel vehicles regularly
Businesses with vehicle fleets should also monitor forecasts weekly to improve operational planning.
South Africa’s Fuel Pricing Formula Under Review
The South African government has confirmed that the country’s fuel pricing formula is currently under review. Officials believe the country remains too dependent on imported refined fuel products.
The proposed South African National Petroleum Company (SANPC) Bill could eventually change how fuel pricing and energy security are managed in the future. However, major structural changes are unlikely to affect June 2026 fuel prices immediately.
Conclusion
The June 2026 diesel price forecast brings welcome relief for South African diesel users after months of extreme fuel pressure. While petrol motorists may still face significant increases due to reduced fuel levy relief, diesel prices are expected to decline noticeably.

To check the latest diesel price forecast accurately, motorists should follow updates from the Central Energy Fund, monitor government announcements, and keep an eye on international oil prices and currency movements. Since projections can still change before the final announcement, staying updated throughout May remains important for both households and businesses.
