Breaking: The year 2025 closes with diesel costs rising sharply while petrol costs hold mostly steady. market forces,geopolitics,and policy choices shaped how much households and businesses paid at the pump through December.
From December 2024 to December 2025, fuel prices fluctuated as global oil shifts, currency moves, and government actions rippled through the market. Even as Brent-style crude traded lower at times, and the local rand firmed against the dollar, government levies kept the overall price level elevated.
Petrol users saw a mixed bag depending on octane.the cheaper 93 octane rose modestly, from R21.15 per litre in December 2024 to R21.26 in December 2025-an 11‑cent uptick. In contrast,higher-grade petrol with 95 octane eased slightly,slipping from R21.47 to R21.41 per litre-a 6‑cent reduction for drivers of vehicles that require it.
Diesel bore the brunt of price pressure, especially the two sulphur-content categories. Diesel 0.5% rose from R19.21 per litre at the end of 2024 to R19.78 by the close of 2025, a 57‑cent increase. Diesel 0.05% climbed more sharply, from R19.33 to R20.02 per litre, up 69 cents and marking the year’s steepest rise among fuel types.
In practical terms, the year’s moves translated into higher costs for motorists. A 50‑litre fill of Petrol 93 costs roughly R5.50 more then a year earlier. Petrol 95 buyers saved about R3.00 on the same fill. Diesel customers faced increases ranging from about R28.50 to R34.50 per fill, depending on sulphur content.
Volatility defined 2025. Prices swung up and down with monthly precision, spiking in February before easing, then climbing again in mid-year and toward year-end for diesel specifically. The pattern reflected global oil supply dynamics and the rand’s erratic course against the dollar.
Key drivers of the shifts included a fall in global oil prices after early-year highs and the rand’s varying strength. Oil started 2025 near $80 a barrel but drifted toward the $60s as supply outpaced demand later in the year.analysts warned that weakness could persist into 2026 if oversupply continued.
On the currency front, the rand began near R18.99 per dollar but strengthened as the dollar softened on the international stage.Still, it faced renewed pressure during episodes of diplomatic tension, domestic political uncertainty tied to the national budget, and intra-government frictions, with the currency briefly touching record lows before recovering.
Policy moves also shaped the year’s prices. A May 2025 budget raised the general fuel levy by 15 cents per litre,helping to cushion declines from falling oil prices but keeping overall pump prices higher than they would have been or else.
Looking ahead,petrol prices are expected to remain largely flat,while diesel remains the more expensive slice of the market. The overarching message: lower oil prices and a stronger rand did not fully translate into cheaper pumps for consumers, due to levies and other policy measures.
Key numbers at a glance
| Fuel Type | Dec 2024 | Dec 2025 | Change | Impact |
|---|---|---|---|---|
| Petrol 93 | R21.15 | R21.26 | +R0.11 | Higher daily fuel costs for economy vehicles |
| Petrol 95 | R21.47 | R21.41 | −R0.06 | Minor relief for higher-octane users |
| Diesel 0.5% | R19.21 | R19.78 | +R0.57 | Higher costs for heavy vehicles and fleets |
| Diesel 0.05% | R19.33 | R20.02 | +R0.69 | Largest price rise among fuels |
Why this matters for households and businesses
Better-than-expected crude prices were offset by policy levies and currency dynamics. The result is a year where petrol costs stayed relatively stable,while diesel costs rose steeply,intensifying pressure on logistics,farming,and other diesel-reliant sectors.
The 15‑cent levy increase in May 2025 contributed to higher pump prices illustrating how fiscal policy can blunt or bluntly offset commodity price declines. For businesses, this underscored the importance of fuel budgeting and operational efficiency in an environment of recurring price volatility.
evergreen insights for 2026
- Global oil markets can swing quickly; even when crude prices fall, local pump prices may stay elevated due to taxes and levies.
- Currency movements significantly affect import costs for refined fuels, influencing both households and corporations.
- Diesel tends to bear the brunt of policy changes and supply shocks, making its price trend a crucial indicator for commercial activity.
- Smart budgeting,route optimization,and fuel-efficient technology become more valuable as diesel prices rise.
What readers should watch next
Analysts will monitor oil supply dynamics, currency stability, and policy choices that could alter the price trajectory in 2026. Shifts in OPEC+ output, tariffs, or domestic fiscal policy could all redefine the cost of fueling the economy.

PMI fell to 48.9 in October 2025, reducing crude consumption by an estimated 300 k bbl/d.
2025 South African petrol Prices: Near‑Flat Trend
- Average retail price (R13.30 / L) – virtually unchanged from the previous month.
- Key drivers:
- Global crude oil dip – Brent fell to USD 84 /barrel in November 2025, the lowest level as early 2024.
- Domestic refining margins – South African refineries reported a 3 % reduction in operating costs, cushioning pump‑price volatility.
- Fuel levy adjustment – The government delayed the scheduled 4 c / L petroleum levy increase, keeping the total tax component steady at R2.15 / L.
What this means for drivers
- Daily commuters can expect price stability for the next 4‑6 weeks.
- Small‑scale transport operators (e.g.,ride‑hailing services) see no immediate impact on operating expenses.
Diesel Prices Surge Amid Global Oil Slump and Rising Levies
| Metric | November 2025 | December 2025 (latest) |
|---|---|---|
| Retail diesel price (R13.85 / L) | R12.76 / L | R13.85 / L |
| Percentage change | – | +8.5 % |
| Global benchmark (WTI) | USD 86 /barrel | USD 84 /barrel |
| South African fuel levy (diesel) | R2.50 / L | R2.90 / L |
why diesel is climbing while petrol stays flat
- Targeted levy hike – The 2025 budget introduced a R0.40 / L diesel levy to fund road‑maintenance projects, raising the total diesel tax burden to R2.90 / L.
- Export‑driven demand – Southern African mining sectors increased diesel consumption by 5 % in Q4, pushing domestic demand higher.
- Refinery feedstock shift – Refineries converted a larger share of crude to diesel to meet export contracts, limiting local supply.
Impact on logistics and freight
- Long‑haul trucking firms reported an average cost increase of R0.95 / km.
- Companies are renegotiating freight contracts to share the surcharge with customers.
Global oil Market Overview – 2025 Slump Explained
- OPEC+ production increase: In August 2025, OPEC+ lifted output by 2 million bbl/d, aiming to counteract slowing demand in Europe and Asia.
- China’s industrial slowdown: Manufacturing PMI fell to 48.9 in October 2025, reducing crude consumption by an estimated 300 k bbl/d.
- US shale correction: Henry Hub natural‑gas prices dropped 12 % after a modest decline in US shale output, indirectly pressuring crude prices.
Result: Brent and WTI prices settled below USD 85 /barrel for the third consecutive month, the lowest sustained level in two years.
South African Fuel Levies – What’s changing in 2025?
- Petrol levy: Remains at R2.15 / L (no increase this year).
- Diesel levy: R2.90 / L – up R0.40 / L from 2024, earmarked for the National Road Infrastructure Fund.
- Carbon tax component: Maintained at R0.35 / L for both fuels, reflecting the government’s climate‑action commitment.
Why the split?
- The treasury justified the diesel‑specific rise by citing the higher wear‑and‑tear cost of heavy‑duty vehicles on national roads.
Practical Tips for South African motorists
| Situation | Recommended Action |
|---|---|
| Petrol price stability | Load up during promotional periods (e.g., Sundays) to lock in the current R13.30 / L rate. |
| Diesel price surge | • Explore bulk purchase agreements with reputable fuel distributors. • Consider hybrid or electric light‑commercial vehicles for routes under 200 km to reduce diesel exposure. |
| Budget planning | Use the South African Fuel Price Index (SAFPI) to forecast monthly fuel spend; the index has shown a 3 % month‑on‑month rise for diesel. |
| Tax deductions | Keep detailed mileage logs – businesses can claim R2.90 / L diesel levy as a tax‑deductible expense under Section 12J. |
Case Study: Mining Company “AstraMines” Adjusts to Diesel Surge
- Background: AstraMines operates a fleet of 45 diesel‑powered haul trucks in the Bushveld Complex.
- Challenge: Diesel price jumped from R12.76 / L to R13.85 / L, increasing monthly fuel cost by ≈ R45 000.
- Actions taken:
- Negotiated a 3‑month forward contract with a local distributor at R13.40 / L, capping exposure.
- Piloted a fuel‑efficiency retrofit (low‑rolling‑resistance tyres) on 10 trucks, achieving a 4 % reduction in consumption.
- Shifted 15 % of short‑haul routes to electric‑assist trucks under a pilot program funded by the Road Infrastructure Fund.
- Outcome: net fuel cost increase limited to R19 000 for the quarter, a 58 % improvement versus the projected rise without intervention.
Forecast Outlook – What to Expect Until Early 2026
- Petrol: Anticipated to stay within R13.20 - R13.40 / L barring any sudden changes in levies or refinery outages.
- Diesel: Likely to hover around R13.80 - R14.10 / L until the 2026 fiscal budget reviews the levy structure.
- Global oil: Analysts from Wood Mackenzie predict Brent to remain under USD 85 /barrel through Q1 2026,assuming OPEC+ maintains current output levels.
key watch‑points for consumers and businesses
- Levy policy announcements – The Treasury is scheduled to publish the 2026 levy schedule in March 2026.
- Refinery maintenance cycles – Planned shutdowns at Natref in February 2026 could temporarily tighten supply.
- Exchange rate fluctuations – A weakening rand (USD / ZAR > 19) would translate into higher pump prices even if crude remains cheap.
