President Donald Trump has warned the Iranian government that "time is running out" to reopen the Strait of Hormuz, setting a definitive 48-hour deadline before the United States initiates a massive expansion of military strikes against the Islamic Republic’s infrastructure.
Writing on his Truth Social platform late Saturday, April 4, 2026, the President stated that the window for a diplomatic resolution regarding the world’s most critical energy artery is rapidly closing. The ultimatum expires at 8:00 PM ET on Monday, April 6, marking a precarious turning point in a conflict that has already decimated global energy markets and halted 90% of typical maritime traffic through the region.
The President’s latest rhetoric follows a ten-day "pause" in strikes on Iranian energy sites, a reprieve Trump claimed was granted to allow for back-channel negotiations mediated by regional partners. However, with the Strait remaining effectively shuttered by Iranian naval assets and drone corridors, the White House appears prepared to pivot from negotiation to total kinetic enforcement.
"They have until Monday night to get those ships moving again or all hell will rain down on them," President Trump wrote, specifically referencing previous threats to target the oil export terminal at Kharg Island and Iran’s domestic power grid.
In Tehran, the response has been one of continued defiance despite the looming deadline. Iranian Foreign Minister Abbas Araghchi, speaking via state-affiliated media, characterised the American peace proposal as a series of "excessive and unreasonable" demands that infringe upon Iranian sovereignty. Araghchi emphasised that while Tehran does not seek a wider war, it will not reopen the waterway under the "shadow of a gun."
The geopolitical stakes remain unprecedented. Since the closure of the Strait in late February following Operation Epic Fury, daily vessel transits have plummeted from an average of 150 to fewer than 15. This bottleneck has forced global shipping to reroute around the Cape of Good Hope, sending crude oil prices to historic highs and straining Western economies.
Pentagon officials confirmed Saturday that U.S. Central Command has positioned additional carrier strike assets within range of Iranian coastal batteries, awaiting the expiration of the President's Monday deadline.
