Oil jumps 6% as Trump imposes 20% toll on Hormuz transit
President Trump’s plan to charge a 20% levy on cargo moving through a U.S.-defended Persian Gulf corridor adds a steep financial penalty to an already perilous transit route, sending crude prices sharply higher.
President Donald Trump announced on Monday that the U.S. will begin charging a 20% fee on all cargo transiting the Strait of Hormuz under American naval protection. The policy immediately rattled energy markets, pushing oil prices up 6% following a violent weekend of skirmishes in the Persian Gulf.
The levy marks a dramatic shift from the U.S. military’s previous posture of escorting commercial ships for free. Washington had previously demanded that Iran fully restore free navigation without tolls. “The U.S.A. will be, from this point forward, known as ‘THE GUARDIAN OF THE HORMUZ STRAIT,’ but as such, and as a matter of FAIRNESS, will be reimbursed, at the rate of 20% on all cargo shipped, for any and all costs necessary to do the job of providing safety and security to this very volatile section of the World,” Trump said on social media, adding that “the process and formation” of his plan will begin immediately.
The toll forces shipping companies and their insurers to weigh a steep new financial burden against the physical risks of the ongoing U.S.-Iran war. Traffic along the U.S.-defended Omani corridor has already nearly vanished because American forces have failed to stop all Iranian projectiles aimed at commercial ships.
As a result, vessels are increasingly turning off their transponders and sailing under the cover of night to use unofficial "dark" routes. Others are paying Tehran to use its controlled northern lane, after Iran used missiles and drones to close off the strait and demand its own tolls for safe passage.
The scale of the potential U.S. charges is significant for global energy supply chains. According to U.S. Central Command, American forces have facilitated the transit of more than 800 commercial vessels carrying 400 million barrels of crude oil through the strait since early May. A 20% levy on that cargo value represents a massive new cost.
The new toll effectively ends American demands for a return to the pre-war status quo, instead mirroring Iran’s own monetization of the chokepoint. With neither Washington nor Tehran willing to back down, Oman has reportedly drafted a proposal to manage traffic by splitting the waterway into two separately controlled routes.
Despite the posturing from both governments, commercial fleets and insurance companies will ultimately determine the reality of the strait. If the combined cost of Iranian attack risks and Trump’s 20% toll proves too high, shippers will simply avoid the corridor altogether, further constraining global crude supplies.
