Road Freight Association warns of inflationary pressure and rising transport rates following March 2026 fuel increase
South Africa’s road freight sector is bracing for renewed cost pressures after a sharp increase in diesel prices for March 2026, a move directly linked to escalating geopolitical tensions and volatility in global oil markets.
According to the Road Freight Association (RFA), the latest adjustment is a serious setback for transport operators and the broader economy.
“The increase in fuel prices in March 2026 is a direct result of upward pressure on the international price of oil due to both supply and logistics risks following the start of hostilities between Iran and the US and Israel. The Road Freight Association (RFA) has noted with both dismay and concern, that the price of diesel is increasing between R0.60 and R0.65 per litre.
Given that diesel is the primary source of fuel for most medium and heavy commercial transporters, this will place an immediate cost burden on daily operations.
Transporters will be faced with – either immediately or later, depending on their operating models or agreements – factoring this increase (and any others that may arise) into their pricing when offering freight transportation services. This means that the gains which were achieved through the gradual reduction of the basic fuel price during 2025, will be erased and the consumer will, inevitably, begin to feel this change in increasing prices at the till.
Unfortunately, fuel is one of the basic input costs in a transportation business that has huge impact on rates for transport. The general economy will also not be immune – with this pressure becoming an upward inflationary force – thus affecting both future decisions regarding the repro rate and the value of the Rand in the pocket of the man on the street.”
Immediate Impact on Transport and Consumers
Diesel remains the backbone of South Africa’s freight logistics network, powering the majority of medium and heavy commercial vehicles responsible for moving goods across provinces and borders.
An increase of between R0.60 and R0.65 per litre significantly affects operational margins, particularly for transporters operating on tight contracts or fixed rate agreements. Companies may initially absorb the increase, but over time, rising fuel input costs typically translate into higher freight tariffs.
As freight costs climb, the knock on effect moves swiftly through supply chains, from manufacturers and distributors to retailers, ultimately impacting the price consumers pay at the till.
Inflationary Pressure and Economic Ripple Effects
Beyond the logistics sector, the RFA warns of broader macroeconomic consequences. Fuel is a foundational input cost across multiple industries, meaning sustained increases can act as an upward inflationary force.
Higher inflation can influence interest rate decisions by monetary authorities and impact currency performance. In practical terms, this affects borrowing costs, household spending power and the overall value of the rand.
The concern is that gains made during 2025, when the basic fuel price gradually declined, could now be reversed, eroding relief previously experienced by businesses and consumers alike.
A Sector Watching Global Developments Closely
With global oil prices responding sharply to supply and logistics risks, South Africa’s fuel pricing structure remains highly sensitive to international developments.
For the freight industry, stability in fuel pricing is critical for planning, contract negotiations and maintaining competitive rates. The RFA’s message is clear that while geopolitical events may be beyond the control of local operators, their economic consequences are very real and immediate.
