South African consumers are being urged to brace for higher prices at the tills following a fresh increase in fuel costs for March 2026. The warning comes from the Road Freight Association (RFA), which has expressed serious concern over the latest diesel price adjustment.
According to the RFA, diesel prices are set to rise by between R0.60 and R0.65 per litre. The association attributes the increase to renewed upward pressure on international oil prices, driven by supply and logistics risks after the outbreak of hostilities involving Iran, the United States, and Israel.
Diesel remains the primary fuel source for medium and heavy commercial transporters. As a result, the increase is expected to place immediate strain on daily transport operations. Freight companies will be forced—either immediately or over time, depending on contractual agreements—to factor the higher fuel costs into their pricing structures when offering transport services.
The RFA cautions that the benefits gained from the gradual reduction in the basic fuel price throughout 2025 could now be wiped out. As transport costs rise, retailers and suppliers are likely to pass these increases down the supply chain, ultimately affecting the prices consumers pay for goods.
Fuel is one of the most significant input costs in the transportation industry, and even modest increases can have a wide-reaching impact on freight tariffs. The broader economy may also feel the pressure, as higher fuel prices can contribute to inflationary trends. This, in turn, could influence future interest rate decisions and affect the purchasing power of ordinary South Africans.
With global tensions continuing to impact oil markets, the RFA has urged businesses and consumers alike to prepare for potential further volatility in fuel pricing in the months ahead.
