Middle East mayhem set to crush SA wallets

As global tensions rise again, the real question is how much more can South African households absorb. Energy markets tightened, grain exports were disrupted and inflation, already elevated after the pandemic, surged worldwide. In South Africa, petrol prices jumped and food costs followed, forcing the South African Reserve Bank (SARB) into an aggressive rate-hiking cycle as inflation pushed beyond the benchmark range of 3% to 6%.

For many households, the conflict was not just a geopolitical event; it quickly translated into higher living costs. Renewed tensions in the Middle East are beginning to produce similar warning signs. Much of the concern centres on the Strait of Hormuz, a narrow maritime passage through which roughly 20% of global oil shipments pass.

Investors have been shifting into safer assets, strengthening the US dollar and placing the rand under pressure. What makes this dynamic so powerful is not geography, but global integration. South Africa may sit far from the conflict, yet it remains deeply embedded in global trade, financial markets and dollar-based pricing systems.

In such an interconnected economy, shocks move quickly through commodity markets and exchange rates, often drawing capital towards US assets and placing additional pressure on emerging-market currencies. There are, however, reasons to believe the current situation may unfold differently from previous crises. Oil prices remain below the peaks reached in 2022 but are more than 18% higher than at the same time in 2025.

Global demand has slowed and inflation has stabilised somewhat. Domestically, however, South Africa enters this period with subdued economic growth, persistent energy and logistics constraints, and limited fiscal space. While recent gains in commodity markets may provide some support against tighter global liquidity conditions, the risk remains significant.

The shock is centred on oil, a commodity at the heart of global trade, at a time when household budgets are already stretched after years of rising prices and high interest rates. When the first reports emerged that the United States and Israel had launched military strikes on Iran, the question for many observers was not only how far the conflict might spread, but how quickly it would filter into prices and household finances. For South Africa, the most immediate transmission channel is the fuel price.

Petrol and diesel prices are determined using an import-parity formula that reflects international oil prices and movements in the exchange rate. Although adjustments occur monthly and include fixedlevies, global oil prices and the value of the rand remain the primary drivers of domestic fuel price changes. When oil prices rise and the rand weakens at the same time, a pattern often seen during periods of global uncertainty, domestic fuel prices tend to increase in the following adjustment cycle.

Fuel price increases are not inflation in themselves, but their secondary effects contribute to broaderinflationarypressures. Transport costs rise, logistics become more expensive and businesses facing higher input costs often attempt topasssome of these increases on to consumers. The result is a familiar chain reaction: fuel prices rise, transport and distribution costs increase, producer prices move higher and consumer prices follow.

Food prices are particularlysensitiveto this process. Energy costs are embedded throughout the agricultural value chain, from farm machinery and fertiliser production to refrigeration and long-distance distribution. As fuel prices rise, cost pressures accumulate across the entire food supply chain.

Recent inflationdatafrom Statistics South Africa has already shown how lower fuel prices helped moderate headline inflation. The reverse is also true. If geopolitical tensions push oil prices upward, transport inflation can rise rapidly and spill over into broader price increases.

Importantly, theburdenof these increases is not evenly distributed. Lower-income households typically spend a greater proportion of their income on food and transportation than wealthier households do. Rural and peri-urban households with long commuting distances face additional strain, while informal workers and small businesses that depend heavily on mobility struggle to absorb rising costs.
