The Strait of Hormuz remains a flashpoint between the US and Iran, jeopardizing a fragile ceasefire and diplomatic efforts. Despite an interim deal signed on June 17 to reopen the vital waterway, "tit-for-tat" strikes have persisted. President Donald Trump declared the ceasefire "over" following recent exchanges, undermining mediators' attempts to maintain diplomatic progress. Iran's resistance to ceding control over the strait, which it views as its primary leverage, clashes with Trump's urgency to restore oil flow ahead of U.S. midterm elections.

Under the interim deal, Iran agreed to allow toll-free passage through the strait for 60 days in exchange for the U.S. lifting its naval blockade on Iranian ports. However, disputes over preferred transit routes—Iran favoring a route near its coast and the U.S. promoting an Omani route—have sparked retaliatory attacks. These clashes have repeatedly tested the ceasefire and the interim deal, complicating broader negotiations on a permanent settlement, including Iran's nuclear program. The U.S. has also revoked a waiver allowing Iran to sell crude oil in dollars, further escalating tensions.

The ongoing friction in the Strait of Hormuz, through which approximately a fifth of the world's oil and LNG passes, has rattled the shipping industry. Companies are warning of increased risks and insurance premiums. The situation's volatility threatens to derail talks and could lead to a full-blown conflict. Mediators are working to establish a hotline for incident prevention, but the immediate focus remains on navigating the disputes over the strait, which has overshadowed progress on nuclear discussions and a potential final settlement.
