In Trump’s Truth Social post on Monday, he insisted that the strait “will remain OPEN, with or without Iran.”

“From now on, the United States will be known as “THE GUARDIAN OF THE STRAIT OF HORMUZ,” but as such, and as a matter of JUSTICE, it will be reimbursed, at a rate of 20% of all cargo shipped, for any and all costs necessary to do the job of providing security to this most volatile section of the world,” he wrote.

The US president added that “the process and training will begin immediately.”

His comments came shortly after he told Fox News that the United States would “probably control” the Strait of Hormuz, alleging that Iran “broke” an agreement made with the United States.

“We are taking over the strait,” he said.

Later on Monday, US Central Command (Centcom) said its forces will “resume blocking maritime traffic in and out of Iranian ports” on July 14.

“The US military continues to support the flow of traffic through regional waters for all vessels that do not violate the blockade,” a Centcom statement said.

In response to Trump’s announcement, Iranian Foreign Minister Abbas Araghchi wrote in a post on

He continued: “Iran has always been the GUARDIAN of the Strait and will remain so FOREVER.”

“Of course, 20% is too much. We will be fair,” Araghchi added.

Meanwhile, a spokesperson for the International Maritime Organization – the UN agency that regulates global shipping – was quoted by the Reuters news agency as saying that “the IMO is firmly opposed to charging fees for passage through straits used for international shipping.”

“There is no legal basis to introduce mandatory tolls simply to transit a strait,” the spokesperson added.

Before Trump’s announcement, Iran’s top military headquarters said it would not allow the United States to “interfere in the management” of the Strait of Hormuz.

In a statement shared by Iranian media, Ebrahim Zolfaghari, spokesman for Khatam al-Anbiya, said that “repeated adventurism and malicious actions” by the United States in the strait have “seriously endangered regional security, international trade, and the passage of oil tankers and commercial vessels.”

Any cooperation with the United States would be considered an act of “war” against Iran’s sovereignty, he added, warning that if the conflict spreads “the flames of war will engulf all countries in the region.”
