The Strait of Hormuz is not just another waterway. It is a critical oil corridor, and Trump’s proposal puts U.S. power, Iranian claims and global shipping costs on a collision course.
Donald Trump says the United States will take control of the Strait of Hormuz, and the U.S. will charge shipping fees or tolls to vessels using the passage, a claim that immediately sharpened the U.S.-Iran confrontation over the strait. The Hormuz charge for shipping matters because the narrow waterway off Iran is one of the world’s most important oil-shipping routes, and any dispute over who controls it can ripple through energy markets, military planning and diplomacy.
According to USA TODAY, Trump made the comments in a July 13 phone interview with Fox News, saying the U.S. would become the “guardian” of the strait after renewed fighting between Washington and Tehran.
A bold claim over Hormuz
Trump’s statement went beyond the usual U.S. pledge to keep shipping lanes open. He said the United States is reinstating a naval blockade on Iran and seeking operational control of the Strait of Hormuz, the passage connecting the Persian Gulf with the Gulf of Oman and the Arabian Sea.
“We’re taking over the strait,” Trump said, according to USA TODAY’s account of the Fox News interview. He also said other countries using the waterway should reimburse the United States for the cost of securing it.
In a later Truth Social post cited by USA TODAY, Trump said the Strait of Hormuz would remain open “with or without Iran” and described the U.S. as “THE GUARDIAN OF THE HORMUZ STRAIT.” He framed the renewed blockade as aimed at Iranian ships or customers, not all commercial traffic.
The most striking part was the proposed price tag. Trump said the U.S. should collect a fee equal to 20% of the value of cargo shipped through the strait to cover security costs, according to the report.
Why this waterway matters
The Strait of Hormuz is one of the world’s most sensitive maritime chokepoints because so much oil and liquefied natural gas moves through it. Even threats involving the strait can jolt markets because traders, governments and shipping firms price in the risk of delays, attacks or insurance spikes.
For Gulf energy exporters, Hormuz is a lifeline. For Iran, it is also leverage. Tehran has repeatedly used the possibility of closing or disrupting the strait as a warning to the U.S. and its allies during periods of heightened conflict.
That is why Trump’s claim is not just symbolic. A U.S. move to “run” or control the strait would be read by Iran as a direct challenge in waters it considers central to its security and regional influence.
It would also put U.S. allies in a difficult spot. Many want the waterway open and secure, but a sweeping American fee system could create new diplomatic fights over who agreed to pay, who benefits and who decides the rules.
The toll plan faces limits
The legal question is immediate: can the United States charge vessels for using an international waterway? USA TODAY noted that transit tolls on international waters are not allowed under international law, though fees can be permitted for specific services.
That distinction matters. Charging for a pilot, port service or direct security escort is different from imposing a broad cargo levy on ships simply because they pass through a strategic route.
The proposal also sits awkwardly beside the Trump administration’s own recent position. Secretary of State Marco Rubio said in June that “no country is allowed to charge tolls or fees on an international waterway,” according to the USA TODAY report.
If the U.S. attempted to collect a 20% cargo-value fee, it would likely trigger resistance from shippers, insurers, energy buyers and foreign governments. It is not clear from Trump’s remarks whether the plan is a policy decision, a negotiating threat or a political message aimed at Iran and Gulf states.
Iran pushed back fast
Iran did not treat Trump’s wording as a throwaway line. Seyed Abbas Araghchi, Iran’s foreign minister, responded on X by arguing that Iran remains the true guardian of the Strait of Hormuz.
His response used Trump’s logic against him. If the country providing safe passage should be compensated, Araghchi suggested, then Iran could claim that role too. He also mocked the proposed 20% charge, saying it was “too much” and that Iran would be “fair,” according to USA TODAY.
The exchange highlights the danger of competing claims over the same waterway. If both Washington and Tehran claim authority to secure, restrict or charge passage, commercial shipping could be caught between rival powers.
Iran’s reaction also signals that the dispute is not only about ships. It is about prestige, sovereignty and deterrence at a moment when both sides are trying to show they are not backing down.
A ceasefire framework unraveled
Trump’s comments came after renewed military strikes and threats shattered hopes for a more stable pause in the U.S.-Iran conflict. USA TODAY reported that the U.S. launched new strikes against Iran on July 12 after Tehran targeted U.S. facilities across the Persian Gulf and said it had again closed the Strait of Hormuz.
Trump said negotiators had believed they had reached a long-term peace plan after an 11-hour meeting, but he accused Iranian leaders of breaking the deal and adding new demands.
That matters because the strait dispute is now tied to the collapse of a broader diplomatic track. A June memorandum between the U.S. and Iran had been intended to reopen the strait and create space for further talks, but the latest exchange suggests that framework has largely fallen apart.
The result is a more volatile mix: military escalation, legal uncertainty, economic pressure and public threats over one of the world’s busiest energy corridors.
What is still unclear
The biggest unanswered question is whether Trump’s comments represent an imminent operational plan or an aggressive bargaining position. “Taking over” a strait is not a simple administrative step. It would require military assets, rules of engagement, coordination with regional partners and a legal theory for enforcement.
It is also unclear whether Gulf allies or other countries shipping through Hormuz have agreed to any reimbursement system. Trump said wealthy nations on the U.S. side should pay, but USA TODAY reported that it was not immediately clear whether Middle Eastern allies had agreed to the fees.
Shipping companies will be watching for practical signals: naval deployments, insurance warnings, rerouting guidance, sanctions language or formal notices to mariners. Oil markets will watch for any sign that the dispute could reduce actual supply, not just raise fears.
The clean takeaway is that Trump’s Hormuz claim has opened several fights at once. One is with Iran over control and deterrence. One is with international law over fees and passage. And one is with the global economy, which has little patience for uncertainty at a chokepoint where politics can quickly become a price shock.
