President Trump threatened Oman with military action on Wednesday if the Gulf ally proceeds with an Iranian partnership to charge fees for vessels transiting the Strait of Hormuz. Speaking during a cabinet meeting, Trump warned of bombing campaigns before quickly backtracking, insisting the sultanate would ultimately comply with U.S. demands.

The warning comes amid escalating tensions following February's U.S.-Israeli attack on Iran, which triggered a months-long conflict spreading across the region. Iran's closure of the strait has already disrupted global shipping routes and rattled financial markets, with energy prices particularly volatile. Trump emphasized that the waterway must remain open to all nations without fee-based control.

Oman's foreign ministry has not responded to the president's remarks. The potential deal between Iran and Oman would establish a fee-collection system for one of the world's most critical maritime chokepoints, through which roughly 20% of global petroleum passes. Such arrangements could fundamentally alter shipping costs and insurance premiums worldwide.

Despite ongoing diplomatic efforts to reopen the strait quickly, the likelihood of immediate breakthrough diminished significantly after this week's intensified hostilities. Trump's contradictory messaging—threatening military action while claiming Oman will cooperate—creates uncertainty for energy markets already grappling with supply chain disruptions.
