Hormuz remains blocked under new ceasefire: Update 3

Updates with changes throughout

The strait of Hormuz remains largely closed to navigation and the US naval blockade of Iranian trade continues despite a ceasefire that President Donald Trump said on Tuesday will continue indefinitely, to give Iranian leaders time to craft a proposal to end the conflict.

The US will "extend the Ceasefire until such time as their proposal is submitted, and discussions are concluded, one way or the other," Trump wrote in a social media post at 4:09pm ET (20:09 GMT). The earlier US-Iran ceasefire was scheduled to expire at 7:50pm ET (23:50 GMT) on Tuesday, Pakistan said earlier in the day.

The Trump administration is casting the extension of the ceasefire with Iran and maintaining the naval blockade as economically damaging for Tehran. "In a matter of days, Kharg island storage will be full and the fragile Iranian oil wells will be shut in," treasury secretary Scott Bessent said on Tuesday. "Constraining Iran's maritime trade directly targets the regime's primary revenue lifelines."

But the Trump administration has no immediate solution for addressing much larger production shut-ins across the Mideast Gulf and the resulting spike in oil and gas prices globally.

Global oil demand has fallen by about 4mn b/d since the start of the war in the Mideast Gulf, compared with supply losses of around 12mn b/d, trading firm Vitol's chief executive Russell Hardy said on Tuesday.

Uncertainty over the course of the US-Iran confrontation pushed May Nymex WTI up by 3pc to $98.48/bl on Tuesday.

US energy secretary Chris Wright, who over the weekend suggested that oil prices would remain elevated through 2027, has had to change his messaging after Trump insisted on Monday that prices would decline as soon as he secures a deal with Iran, which he suggested would happen quickly.

"I don't know the future of energy prices," Wright told a Senate panel on Tuesday, but he added that US retail gasoline prices "peaked about a week or so ago".

Tehran, too, appears to believe that it holds the upper hand in the confrontation with Washington. "If the US wants to maintain the shadow of war, it must also consider the strait of Hormuz completely closed," Iran's Tasnim news agency, which is linked to Iran's Islamic Revolutionary Guards Corps, said in an opinion piece soon after Trump's ceasefire announcement.

Officials in Tehran did not immediately react to Trump's announcement of a ceasefire extension. Tehran did not request an extension and will not reopen the strait of Hormuz as long as the US naval blockade continues "and, if necessary, (Iran) will break the blockade by force", Tasnim said.

Trump said Pakistani leaders — who are mediating the peace talks — asked him to hold off on attacks so that Iran's leadership — which he claimed was "fractured" — could come up with a "unified proposal". Trump said the US military will continue its naval blockade against Iran and remain "ready and able".

The US naval blockade, in effect since 13 April, has forced 28 Iranian vessels to turn around and return to ports in Iran, the Pentagon said on Tuesday.

The US Navy seized a tanker carrying Iranian crude in the Indian Ocean on Tuesday, two days after disabling and boarding an Iran-flagged vessel in the Arabian Sea.

"Blockading Iranian ports is an act of war and thus a violation of the ceasefire," Iran's foreign minister Abbas Araqchi said hours before Trump's announcement. "Striking a commercial vessel and taking its crew hostage is an even greater violation," Araqchi said.

"I sincerely hope that both sides will continue to observe the ceasefire and be able to conclude a comprehensive ‘Peace Deal' during the second round of talks scheduled at Islamabad for a permanent end to the conflict," Pakistani prime minister Shehbaz Sharif said in a social media post Tuesday, after Trump's announcement. Sharif did not specify when the US and Iranian delegates will meet next.

US vice president JD Vance, who led the unsuccessful round of talks with an Iranian delegation on 11-12 April, is no longer planning to head to Pakistan on Tuesday for another round, the White House said after Trump's ceasefire announcement.
