Currency world news: Bessent will announce on Monday what the Trump administration calls the harshest Iran sanctions in history. Rezaei warns that if economic pressure continues, Iran will halt all oil exports through the Strait of Hormuz and the Persian Gulf. Bessent says the sanctions will force allies into a binary choice, potentially spreading secondary sanctions risks to shipping, insurance, and financial intermediaries and further tightening global crude oil logistics. It is expected that Monday’s announcement will trigger volatility in crude benchmarks, tanker freight rates, and regional equities.
