Global financial markets have entered a period of heightened uncertainty, with South Africa’s currency coming under sustained pressure as geopolitical tensions disrupt energy supply expectations.
The rand has weakened notably over recent weeks, reflecting a broader shift toward safer assets. By Monday, 23 March, the currency had fallen to around R17.25 against the US dollar, driven largely by escalating conflict involving the United States, Israel, and Iran.
Energy risks drive market instability
The turning point came after the United States launched “Operation Epic Fury” against Iran on 28 February 2026. Since then, oil markets have experienced sharp fluctuations, with traders reacting to the possibility of prolonged disruptions in the Strait of Hormuz — one of the world’s most critical oil transit routes.
According to Investec Chief Economist Annabel Bishop, uncertainty surrounding the duration of shipping disruptions has become a key driver of market volatility. As oil prices surged above $100 per barrel, concerns over global supply intensified, placing additional strain on oil-importing economies like South Africa.
A brief moment of optimism emerged when US President Donald Trump announced that Washington had entered discussions with Iran aimed at resolving the conflict. He indicated that military action would be delayed for five days to allow diplomacy to proceed.
Markets responded quickly. Oil prices dipped below $100 per barrel, while risk-sensitive currencies, including the rand, strengthened. The rand briefly recovered to an intra-day level of R16.74 per dollar.
Conflicting signals reverse gains
However, the recovery proved short-lived. Iranian officials denied that any negotiations were taking place, contradicting the US narrative and reigniting uncertainty across global markets.
Oil prices rebounded above $100, reaching approximately $103 per barrel later in the day. The rand weakened again, trading near R16.86 by the afternoon.
The impact of rising oil prices is expected to be significant for South Africa’s domestic economy. Fuel price projections indicate sharp increases from 1 April, with diesel expected to rise by more than R9.00 per litre, petrol by R5.42 per litre, and illuminating paraffin nearing R11.00 per litre.
These increases are likely to have widespread consequences. South Africa’s logistics and supply chains rely heavily on diesel, meaning higher transport costs will feed into broader inflation. Agricultural production is also at risk, as the country imports around 80% of its fertiliser needs.
Fertiliser costs typically account for between 35% and 50% of production expenses for key crops such as maize. Higher input costs could reduce usage, lower yields, and ultimately contribute to rising food prices.
This presents a challenge for economic growth. Agriculture played a key role in supporting South Africa’s economy in the previous year, but rising costs and constrained supply conditions now pose downside risks.
At the same time, the rand remains highly sensitive to global risk sentiment. Since the outbreak of the conflict, the currency has lost nearly 5% of its value, reflecting sustained pressure on emerging market assets.
Inflation concerns have also intensified, complicating the outlook for monetary policy. Expectations for interest rate cuts have largely faded, with markets increasingly anticipating that rates will remain elevated for longer — or potentially rise.
While diplomatic developments could still alter the trajectory, financial markets continue to react sharply to each new development, underscoring the fragility of the current environment.
