The South African rand weakened toward 16.5 per USD, reaching a new one-week low, as investors moved into the US dollar following the collapse of US–Iran peace talks. Gold prices also declined, removing an important source of support for the currency. At the same time, renewed threats of a Strait of Hormuz blockade pushed oil prices higher, heightening global inflation risks and reinforcing expectations that monetary policy will remain restrictive worldwide.
For South Africa, higher oil prices typically translate into increased fuel import costs and more persistent inflation, strengthening expectations that domestic interest rates will remain elevated for longer. The rand faced additional downward pressure from a fresh bout of diplomatic tension, after reports that the US declined to accredit South Africa’s delegation to the G20 finance meetings in Washington, scheduled for April 13–18.
