Fuel Price Going Up or Down: Latest View
Trying to budget for the month ahead in South Africa usually involves one critical question: is the fuel price going up or down? Because fuel prices are regulated by the government and change on the first Wednesday of every single month, keeping track of daily market shifts can save you serious money at the pumps.
Before looking at the numbers, it is vital to know where we stand in the monthly cycle. Are we looking at a speculative forecast, or has the official rate been locked in?
Confirmed vs Forecast Movement
- The Daily Forecast (Live Indicators): Throughout the month, the Central Energy Fund (CEF) releases daily over- or under-recovery data. This tells us whether the current exchange rate and oil prices are working in our favour or against us. This is an indicator, not a guarantee.
- The Official Adjustment: On the Friday or Monday preceding the first Wednesday of the month, the Department of Mineral Petroleum and Resources (DMPR) announces the finalized, official price changes.
Current Market Snapshot (September 2026 Forecast):
- Petrol (93 & 95 ULP): Expected decrease of roughly R1.52 to R1.63 per litre.
- Diesel (50ppm & 500ppm): Expected decrease of roughly R1.08 to R1.61 per litre.
- Illuminating Paraffin: Expected decrease of roughly R1.59 per litre.
- Status: Forecast Phase (Based on volatile mid-July CEF data; early massive cushions are actively shrinking due to sudden international crude oil spikes).

Expected Petrol, Diesel and Paraffin Movement
Fuel products don’t always move in tandem. It is common to see petrol prices drop while diesel climbs, or vice versa, due to different international refining margins and global demand cycles.
Expected Increase/Decrease Breakdowns
When evaluating the expected fuel price next month, we have to separate consumer petrol from commercial diesel grades:
- Petrol (93 ULP & 95 ULP): Retail petrol prices are strictly fixed by law. Whether you fill up at a premium highway station or a quiet suburban garage, you pay the exact regulated price per litre for your zone. Current mid-month indicators point toward a welcome, yet diminishing, decrease for August.
- Diesel (500ppm & 50ppm): Unlike petrol, diesel prices are deregulated at a retail level. The figures published by the media are the wholesale price indicators. Individual fuel stations add their own retail margins, which is why diesel prices vary from station to station. Fleet operators tracking the wholesale diesel price forecast South Africa pages will get a clearer view of bulk commercial procurement costs than consumer retail estimates.
- Illuminating Paraffin: Crucial for millions of South African households for heating and cooking, paraffin pricing closely tracks global distillate markets similarly to diesel.
If you are planning your personal budget or tracking commercial logistics costs, looking at the broader fuel price forecast South Africa data allows you to anticipate structural shifts before they hit your balance sheet.
What is Driving the Change
The South African fuel pricing mechanism relies on the Basic Fuel Price (BFP), which simulates what it costs to buy fuel from international refineries and land it on our shores.
Key Price Drivers
Two primary forces dictate whether we see a fuel price increase next month or a welcomed fuel price decrease next month:
- The US Dollar / South African Rand Exchange Rate ($/R): Because oil is traded globally in US Dollars, the strength of the Rand is half of the equation. If the Rand strengthens against the USD, it costs fewer Rands to import the same amount of fuel, driving an over-recovery (potential price drop). If the Rand tanks, fuel prices usually spike.
- Global Brent Crude Oil Prices: The cost of raw crude oil on the international market directly dictates refinery output costs. Supply cuts, geopolitical tensions, or shifting global economic demand can rapidly push Brent Crude up or down.
[Oil Price Up] + [Rand Weakens] = Fuel Price Increase (Under-Recovery)
[Oil Price Down] + [Rand Strengthens] = Fuel Price Decrease (Over-Recovery)
In July, a massive initial price drop cushion was built on a brief US-Iran ceasefire that dropped oil to $72 a barrel. However, the resumption of hostilities in the Middle East has sent oil spiking past $80–$85 a barrel, actively eroding our over-recoveries. Furthermore, because National Treasury’s temporary relief has ended, the General Fuel Levy is back at its full rate, leaving pump prices fully exposed to international volatility.
Additionally, local elements like the Slate Levy are adjusted periodically by the DMPR to manage self-insurance balances for the oil industry. For a deeper breakdown of this math, read our guide on how fuel price predictions are calculated.
Inland vs Coastal Impact
South Africa is split into distinct pricing zones. Because fuel is imported primarily via coastal ports and transported inland via pipelines, rail, and road networks, transporting that fuel costs money.
- Coastal Prices: Cheapest for petrol because there are no major inland transport costs added to the BFP.
- Inland Prices (Gauteng, Free State, etc.): Higher due to the inclusion of zone differential costs to cover the expense of moving fuel hundreds of kilometers away from the coast.
| Fuel Grade | Coastal Base Rate (September 2026) | Inland Base Rate (September 2026) |
| 93 Unleaded Petrol | R25.97 / L | R26.76 / L |
| 95 Unleaded Petrol | R26.05 / L | R26.92 / L |
| 50ppm Diesel (Wholesale) | R28.68 / L | R29.56 / L |
When asking yourself, “Should I top up my tank tonight?”, the decision often hinges on how big the impending shift is. Motorists looking to optimize their weekly spend can play around with the should I fill up before petrol price increase calculator or figure out exactly how much can I save before petrol price increase to see if waiting in a queue at the garage is actually worth the real-world savings.
