Markets Eye Relief as US-Iran Deal Raises Hopes for Oil, Inflation and the Rand

Global markets are entering the week with cautious optimism as a proposed peace deal between the United States and Iran appears to be moving closer to signature. In this week’s market review, TreasuryONE currency strategist André Cilliers said the presence of a signing date and location suggested that markets were increasingly pricing in a resolution, even though key details around nuclear discussions and the release of frozen assets remain unresolved.

The potential reopening of the Strait of Hormuz is expected to bring some relief to oil markets, but Cilliers cautioned that the economic impact of the conflict will not disappear overnight. With the disruption having lasted more than 100 days, ships, refineries and supply chains will need time to normalise, meaning the inflationary effects already working their way through the global economy could still be felt in the coming months.

Oil prices did not remain above the $100 level during the conflict, partly due to weaker demand dynamics and the use of strategic reserves, particularly in China. However, as supply routes reopen and confidence improves, oil prices could begin to ease, offering some support to the inflation and interest-rate outlook. This will be closely watched by central banks, including the US Federal Reserve, which will need to decide whether to focus on recent inflation pressure or take a more forward-looking view if energy prices start to normalise.

For South Africa, the rand has already benefited from a weaker dollar and improved emerging-market sentiment. Cilliers noted that if the agreement is signed and holds, the rand could move into a stronger trading range of around R15.80 to R16.20 against the dollar. However, should the deal fail to materialise, the currency could return to its previous weaker range, underlining that markets are likely to remain sensitive until the agreement is formally concluded.
