Secretary of State Marco Rubio warned Friday in Helsingborg, Sweden, that Iran is attempting to impose a tolling system on the Strait of Hormuz and called any such scheme illegal, even as U.S. forces have been rerouting commercial traffic away from the waterway.
U.S. Central Command said Thursday that American forces have redirected 94 commercial ships so far during what it described as a blockade of Iranian ports. The UK Maritime Trade Operations agency on Thursday labeled threats in the Strait of Hormuz and the Persian Gulf "critical," and said traffic through the strait was being "significantly reduced."
The flurry of statements and movements accelerated Friday. President Donald Trump said the United States did not want tolls in the strait. House Republican leaders, meanwhile, canceled a planned vote on a resolution that would have constrained the president’s ability to use military force against Iran without congressional approval.
Rubio, speaking in Helsingborg where he said he had traveled to attend a NATO foreign ministers meeting, emphasized that any Iranian attempt to charge passage through the internationally critical waterway would be unlawful and unacceptable to other states. He said Washington has been working primarily through Pakistan to de-escalate the crisis; a Pakistani security source told a news outlet on Friday that Pakistan’s military chief, Field Marshal Asim Munir, was heading to Tehran as part of efforts to broker a U.S.-Iran arrangement.
The numbers underline why the issue is urgent: 94 commercial vessels diverted and sustained warnings from the UK agency that shipping volume is markedly down. For countries dependent on oil and trade routes that thread the strait, those disruptions are practical and immediate. Diplomats are racing to prevent a change in the rules for an international waterway that, officials warn, could set a global precedent.
Context helps explain the stakes. The Strait of Hormuz is being described by officials as a critical chokepoint for global shipping, and the current episode centers on two linked developments: an effective blockade of Iranian ports that has prompted U.S. naval rerouting, and what U.S. officials characterize as an Iranian effort to erect a tolling regime in international waters. That mix of military maneuvering and diplomatic alarm has prompted urgent outreach to regional players and beyond.
The tension in the story is straightforward but consequential. On one hand, the president publicly disavowed any interest in a toll system; on the other, American forces are actively redirecting merchant traffic and Congress saw fit to shelve a binding test of its authority on military action. Those moves point to a mismatch between public reassurance and the preparations on the water and in capitals. At the same time, Rubio’s account that Pakistan is the primary interlocutor opens another friction point: Washington appears to be relying on quiet diplomacy through a third party even as it sustains a visible maritime response.
Diplomacy, not force, is now the linchpin the region is watching. Pakistan’s reported trip to Tehran will be one of the earliest and most consequential tests of whether back-channel negotiations can halt what U.S. officials call an illegal tolling attempt. If those talks succeed, the immediate pressure on shipping lanes could ease. If they fail, the combination of fewer transits, continued redirections of commercial traffic and a paused congressional check on the president’s authority will leave the United States and its partners with fewer clean options.
The central unanswered question is sharp: can the Pakistani-led diplomatic effort secure an agreement that neutralizes Iran’s tolling push before the temporary rerouting of ships and the shrinking of traffic through the strait harden into a new, riskier status quo?
