March 2026 Fuel Price Adjustment: What It Means for Your Business
The Department of Petroleum and Mineral Resources has published the official fuel price adjustments taking effect from Wednesday, 4 March 2026 — and increases are back on the table. While fuel prices have been hovering at four-year lows, the current upward movement signals that the window of relief may be closing.
| Fuel | Change |
|---|---|
| Petrol 93 | increase of 20 cents per litre |
| Petrol 95 | increase of 20 cents per litre |
| Diesel 0.05% (wholesale) | increase of 62 cents per litre |
| Diesel 0.005% (wholesale) | increase of 65 cents per litre |
What’s Driving the Increase?
The primary driver behind the March adjustment is the rise in international product prices during February.
According to the Department:
- The average Brent Crude oil price increased from US $64.08 to $69.08.
- Oil prices surged during the month due to geopolitical volatility and escalations between the US and Iran, including military actions involving the US and Israel.
- Increased global shipping costs further contributed to price pressure.
The South African rand showed resilience, which helped cushion the full impact. Without currency strength, petrol increases could have approached 35 cents per litre and diesel close to 80 cents per litre.
However, the cushioning effect was not enough to prevent upward adjustments entirely.
Why Diesel Increases Matter More
For industrial users, transport fleets, mines, farms, and manufacturers, diesel is not discretionary — it is operational.
A 62–65 cent increase per litre may appear manageable at surface level. But when applied to:
- High-volume monthly consumption
- Multi-site operations
- Long-haul logistics
The financial impact compounds rapidly.
Fuel remains one of the largest controllable operating expenses in diesel-dependent sectors.
The Bigger Picture: Are Further Increases Likely?
While prices remain comparatively low relative to historical peaks, current geopolitical instability and global supply uncertainty suggest continued volatility.
With tensions in the Middle East still unfolding and oil markets reacting sharply to developments, March may not be the final adjustment upward.
Businesses should not plan based on short-term relief but rather on structured fuel strategies.
How Businesses Should Respond
Price movements are beyond any individual company’s control.
Preparation, however, is not.
Forward planning can include:
- Securing reliable supply agreements
- Evaluating storage capacity
- Budgeting for volatility rather than stability
- Waiting for the next increase often means reacting too late.
