South Africa’s rand has weakened to its third-worst ranking among emerging-market currencies after the United States refused to lift its blockade of the Strait of Hormuz, with Iran-bound peace talks in Pakistan still uncertain as of Tuesday morning and the country’s financial markets absorbing the shock of R34.1 billion in foreign bond sell-offs.
Investec Chief Economist Annabel Bishop said the rand is now 3.5% weaker against the US dollar than it was before the Iran-US war began, trading at R16.34 to the dollar, R22.10 to the pound and R19.23 to the euro as of Monday afternoon.
Foreigners dump South African bonds as Hormuz blockade bites
The sell-off is sweeping and accelerating.
“Foreigners have sold R34.1 billion worth of South African bonds, weakening the rand to the third-worst performing emerging market currency in the Bloomberg ranking to date since before the Middle East war started,” Bishop said in a Monday note published by BusinessTech.
South Africa has been grouped alongside the Philippine Peso, Thai Baht, South Korean Won, Hungarian Forint, and Mexican Peso as a high-risk emerging-market play.
The reclassification marks a stark reversal: prior to the Iran war, the rand had been placed in a positive-sentiment grouping of developing economies. Bishop noted that the rand has also emerged as the most volatile currency in that basket, with implied volatility rising sharply.
The direct trigger is the US-imposed blockade of the Strait of Hormuz. US President Donald Trump declared on Monday that his administration is “highly unlikely” to renew a ceasefire with Iran ahead of scheduled peace talks in Pakistan, according to AP News.
Trump has repeatedly insisted that the blockade will not be lifted until a comprehensive deal is reached, keeping oil prices elevated and emerging markets on edge.
Petrol prices and interest rates under pressure
South Africa’s pain is not limited to the currency markets. Brent crude oil is currently trading at approximately $95 a barrel, a level that economists at Schroders and Bloomberg project will only decline slowly.
Bishop warned that “local fuel price recoveries are pointing to another massive increase in petrol and diesel prices for May,” adding that any cut remains highly unlikely given the trajectory of crude oil futures.
The inflationary impact of higher fuel costs is expected to push South Africa’s Consumer Price Index higher through the second quarter of 2026.
“The war in Iran is only seen by financial markets currently to allow traffic in the Strait of Hormuz to return to normal by the end of June,” Bishop said, a timeline that would keep pressure on both the rand and the petrol price through at least the middle of the year.
The South African Reserve Bank’s Monetary Policy Committee is now widely expected to respond with a 25-basis-point interest rate hike at its May meeting, a move that would push up the cost of home loans, vehicle finance, and business credit.
What happens next
The next significant market-moving event is the publication of March’s Consumer Price Index data this week, which economists broadly expect will remain close to February’s 3.0% year-on-year reading.
South Africa’s next official petrol price announcement will follow shortly thereafter, with May figures expected to confirm a substantial increase.
