U.S. and Iran Reach Preliminary MOU to Reopen Strait of Hormuz

President Trump warns of military action if terms are violated even as oil prices drop and negotiators head to Geneva.

The United States and Iran have moved from a draft framework to a formal memorandum of understanding (MOU) aimed at de-escalating the ongoing conflict and reopening the Strait of Hormuz. The agreement, which has already sparked a reaction in global energy markets with oil prices dipping below $80, establishes a 60-day window for further negotiations. Core components of the deal include the dilution of Iran’s highly enriched uranium stockpile under international oversight and a commitment from Tehran not to pursue nuclear weapons in exchange for maritime relief. Despite the diplomatic progress, President Trump has maintained a forceful posture, stating that the U.S. remains prepared to "attack Iran again" or "bomb the hell out of them" should Tehran fail to comply with the MOU's provisions. The deal has faced immediate friction as Iranian negotiators indicated they intend to implement a fee system for ships crossing the Strait of Hormuz after an initial fee-free period, a move that may conflict with U.S. interpretations of the maritime agreement. The broader regional situation remains volatile. While the U.S. and Iran negotiate, Hezbollah-linked fighting continues in southern Lebanon, underscored by a drone attack that wounded five Israeli soldiers within the last 24 hours. A formal signing ceremony for the MOU is expected to take place in Geneva, Switzerland, on Friday, with Vice President JD Vance reportedly scheduled to attend on behalf of the Trump administration. France has also expressed readiness to support a maritime monitoring mission in the Strait to ensure the agreement holds.
