President Trump posted an April 5 Truth Social ultimatum giving Iran until April 7 to reopen the Strait of Hormuz or face U.S. strikes on power plants and bridges. The Strait carries ~20% of global oil; Iran has disrupted transit amid Operation Epic Fury. In a Fox interview he also said the U.S. covertly sent weapons to Iranian protesters via Kurdish channels, claimed Iranian security forces killed ~45,000 demonstrators, and warned the U.S. might seize oil if no deal is reached. Comments follow ongoing U.S./Israeli strikes and Iranian missile and drone responses.

The story reports a direct U.S. threat to strike Iranian infrastructure tied to a deadline (April 7) and highlights that the Strait of Hormuz carries ~20% of global oil and has had disrupted transit—facts that materially raise near-term geopolitical and commodity-market risk. It also confirms covert U.S. arms transfers to protesters and ongoing reciprocal strikes, increasing the likelihood of further escalation. Those concrete, time-bound developments support a negative short-term sentiment for risk assets and mark this as market-moving news for short-term traders.
