Trump reinstates Iran port blockade and vows 20% charge on cargo passing through Hormuz

President Donald Trump has said the US is reinstating a naval blockade of Iranian ports and will impose a 20% charge on all cargo shipped through the Strait of Hormuz following days of escalating strikes between the two countries.

He said this would stop “Iran’s ships or customers” from entering or leaving the key oil shipping route, but “all other countries will have fair and open use of the Strait”. The blockade will be in effect from 16:00 Eastern Time (20:00 GMT) on Tuesday.

Iran’s foreign minister later said whoever provides safe passage “should be compensated for this service”, but Iran would remain the strait’s “GUARDIAN” – using Trump’s word.

Tehran and Washington clashed over the strait’s control after exchanging strikes in the region overnight and on Monday.

The US said it carried out strikes against military targets in Iran, targeting air defence systems, coastal radars, and missile and drone sites.

Iran said it responded by striking US military bases in Kuwait, Jordan and Bahrain, and radars in Oman.

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

“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,” he wrote.

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

His comments came shortly after he told Fox News the US would “probably run” the Strait of Hormuz, claiming that Iran “broke” a deal that was made with the US.

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

Later on Monday, US Central Command (Centcom) said its forces “will resume blockading maritime traffic entering and exiting Iranian ports” on 14 July.

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

Responding to Trump’s announcement, Iranian Foreign Minister Abbas Araghchi wrote in a post on X: “POTUS is absolutely right. Whoever provides secure and safe passage of commercial vessels through the Strait of Hormuz should be compensated for this service.”

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

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