Trump Ultimatum to Iran: Reopen Strait of Hormuz in 48 Hours or US Strikes Iranian Energy Sites
US President Donald Trump issued an ultimatum to Iran on 22 March: Tehran has 48 hours to fully reopen the Strait of Hormuz or the US will strike Iranian oil-related and energy infrastructure. Iranian officials and the IRGC responded with defiance, warning of retaliation and signaling that Iran could escalate maritime disruption—potentially moving from partial restrictions to a complete closure of the chokepoint. The dispute is unfolding amid an ongoing US-Israel-Iran conflict cycle, with reports of recent strikes and counterstrikes. Trump’s threat to target power plants—including references to nuclear-related energy infrastructure—raises the risk of violations of international humanitarian law and increases the likelihood of broader regional retaliation. Markets are likely to treat the Strait of Hormuz as the central risk driver: even limited restrictions or insurance/sailing premium spikes can quickly translate into energy price shocks and shipping disruptions.
