Ceasefire Uncertainty Keeps Markets on Edge as Inflation Risks Build

Global markets entered the week with renewed uncertainty as questions persisted over the status of the Strait of Hormuz and the durability of the current ceasefire. According to TreasuryONE’s latest weekly market review, mixed signals from Iran and the United States have left investors with few clear answers on whether negotiations will begin or whether the conflict will escalate again. With the ceasefire due to expire imminently, markets remain highly sensitive to every new headline.

TreasuryONE currency strategist André Cilliers said the bigger issue is no longer the day-to-day swings in rhetoric, but the broader economic impact of prolonged uncertainty. The absence of consistency is making planning difficult for businesses and consumers alike, while the threat of renewed conflict continues to weigh on global growth, inflation and interest rate expectations. In his view, this lack of clarity is becoming one of the most damaging aspects of the current environment.

For South Africa, the inflation implications are becoming harder to ignore. Higher fuel costs are expected to feed through into consumer prices, with additional pressure potentially coming from wider supply-chain effects. Cilliers noted that this creates a difficult policy backdrop for central banks, including the South African Reserve Bank, which may feel compelled to respond to inflation risks even as higher interest rates would place further pressure on households and businesses.

Despite the global volatility, the rand has held up better than might have been expected in previous periods of severe risk aversion. Even so, short-term spikes and pullbacks have become more frequent, reflecting a market driven by geopolitical headlines rather than fundamentals.
