South Africa's latest fuel price adjustment, which saw petrol prices increase while diesel prices declined, highlights the volatility that continues to shape business operating costs. For small and medium enterprises (SMEs) involved in cross-border trade, however, the impact extends far beyond the petrol pump.

Against a backdrop of constrained margins and economic uncertainty, many SMEs are having to reconsider pricing, supplier relationships, inventory, cash flow, and growth planning.

According to James Booth, Head of Revenue at Verto, the current fuel environment is creating a knock-on effect that smaller businesses are often not structurally equipped to absorb.

“Fuel costs don’t exist in isolation,” he says.

“They feed directly into transport, logistics, imported goods, supplier pricing, and ultimately the cost of doing business. For businesses operating on tight margins, ongoing fluctuations in fuel and transport costs create pressure at almost every stage of the value chain.”

The pressure is particularly significant in South Africa, where many companies rely on imported goods, raw materials, or cross-border supplier networks that are sensitive to both transport costs and currency movements. Because oil and fuel are priced in US dollars, local fuel costs are also amplified by rand weakness and foreign exchange fluctuations.

While the latest fuel price adjustment delivered mixed outcomes for motorists, it serves as a reminder of the increasingly complex operating environment facing SMEs involved in cross-border trade. Fuel costs, exchange rate movements and trade-related expenses continue to shift in response to global and local market forces, making long-term planning and forecasting increasingly difficult. For many businesses, that level of volatility can be just as challenging as the cost increases themselves.

While additional cost pressure may first be felt through transport and logistics costs, the knock-on effects can quickly spread across regional supply chains, imported goods, and supplier relationships. For small businesses reliant on predictable delivery schedules or imported inputs, even relatively small cost increases can have significant implications for profitability and planning.

“SMEs often don’t have the same financial buffers or procurement flexibility as larger corporates,” Booth explains. “A sudden increase in transport or import costs can force difficult decisions around pricing, stock orders, payment timing, or even whether expansion plans remain commercially viable.”

The challenge is not only higher costs, but growing unpredictability. Businesses managing supplier payments across borders must now contend with fluctuating shipping expenses, exchange rate movements and tightening cash flow cycles simultaneously.

For importers and distributors in particular, this creates a difficult balancing act between protecting margins and remaining competitive in a price-sensitive market.

“As economic pressure becomes more persistent, businesses are having to think far more carefully about operational resilience,” says Booth. “That includes everything from when they pay suppliers to how they manage foreign currency exposure and forecast future costs.”

This environment may also place additional pressure on regional trade ambitions for SMEs looking to expand into African markets, where logistics and cross-border payment costs already present significant barriers to growth.

Small businesses contribute substantially to South Africa’s employment and economic activity, making their ability to navigate rising operational costs increasingly important for broader economic stability.

“What this is exposing is how interconnected local businesses are with global trade and financial systems,” Booth says. “The challenge facing SMEs is no longer simply managing higher costs but adapting to an operating environment where global pressures are playing a far greater role in shaping local business decisions.”
