ERBIL, Kurdistan Region of Iraq – US President Donald Trump said Monday that Washington is reinstating its naval blockade of Iran, while keeping the Strait of Hormuz open to non-Iranian shipping in return for a charge of 20 percent on shipped goods in exchange for vessels' protection.

“The Hormuz Strait is OPEN, and will remain OPEN, with or without Iran,” Trump wrote on the Truth social platform, while adding that Washington is “reinstating the Iranian blockade” in the strategic waterway, referring to the restriction of vessels seeking to avail of Iranian ports in the Gulf. 

The blockade was previously in place from April and had seen over 100 commercial vessels redirected by US forces after it was lifted in mid-July amid Washington and Tehran reaching a provisional peace agreement.

“All other countries will have fair and open use of the Strait. 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 added.

“The process and formation will begin immediately.”

The comments followed an earlier warning Monday by Iran's Islamic Revolutionary Guard Corps (IRGC), which said it would not allow US interference in the management of the Strait of Hormuz.

Any transit through the Strait of Hormuz without prior notice to Iran would face "severe disruption," the Khatam al-Anbiya Central Headquarters said.

"Any cooperation with the US and logistical support for that country's aggressor military will be considered a war against Iran's sovereignty and national security,” it added.

Since the start of the US-Israel war with Iran in late February, Tehran has shut off the Strait of Hormuz, a key waterway responsible for the transport of roughly 20 percent of the world’s oil, sharply driving up global oil prices.

The free navigation of the waterway has been a key Washington demand in the memorandum of understanding reached with Iran to end hostilities and return to talks.

However, Trump has appeared increasingly frustrated with the notion of free transit in the waterway, which he told Fox News on Monday had operated under US protection “for 50 years” free of charge.

“We guarded it for nothing,” the president said.

Iran has also spoken of their desire to implement a tolling mechanism through the strait.

On Monday, Iran’s foreign ministry said that the US was “so impatient” during the ceasefire that it did not allow Tehran’s one-month period to fulfill its Strait of Hormuz commitments to expire, adding that Tehran will not upload the memorandum with the US if Washington fails to honor its commitments to end the war in the Middle East.

Renewed tit-for-tat strikes started after the US Central Command (CENTCOM) alleged that Iran had “blatantly attacked” a Cyprus-flagged container ship transiting the strait.

Since then, hostilities have resumed between Iran and the US, with Washington targeting sites in southern Iran, primarily near the Strait of Hormuz, while Iran has targeted regional countries, citing that they host US military bases.
