Oil prices moved lower over the past week as markets responded to renewed diplomatic talks between the United States and Iran, with negotiations reportedly continuing in Switzerland. In this week’s TreasuryONE and ETM Analytics market review, André Cilliers said the decline in oil prices suggested that markets were pricing in a more constructive outlook, although tensions in the Middle East remain a key source of volatility.

The potential reopening and continued movement through the Strait of Hormuz has helped ease some immediate concerns around global oil supply. However, Cilliers cautioned that risks remain, particularly with ongoing tension between Israel and Hezbollah. For now, lower oil prices are positive for global energy costs and could provide some relief to fuel prices and inflation expectations, including in South Africa.

In the United States, attention now turns to upcoming inflation data, particularly Core PCE, which is closely watched by the Federal Reserve. While the Fed left interest rates unchanged at its most recent meeting, the tone from policymakers remained hawkish. If inflation remains above target, markets could begin pricing in the possibility of a change in the US interest-rate path later this year.

For the rand, Cilliers said he remains comfortable with a trading range of around R16.25 to R16.75 against the dollar. The currency has benefited from improved sentiment, lower oil prices and a more constructive domestic backdrop, but sustained rand strength will require fresh momentum. Over the next 60 days, markets will closely watch whether peace talks hold, how oil prices respond, and what this means for inflation and interest-rate expectations in both the US and South Africa.
