Oil Tankers Use New Route Through Strait of Hormuz
Iran Says Route Is 'Unacceptable' and 'Dangerous'
Key Takeaways:
- Several tankers exited the Strait of Hormuz June 25 via a new U.N.-backed coastal route along Oman despite Iranian threats against vessels using it.
- The alternative passage could ease global economic pressure and reduce Iran’s leverage in U.S. talks as oil prices fall near prewar levels and transit traffic recovers.
- The U.S. and Iran are negotiating details of a 60-day interim deal while tensions persist, including Iranian warnings and regional clashes involving Israel and Hezbollah.
DUBAI, United Arab Emirates — Several tankers made their way out of the Strait of Hormuz on June 25 using a new route promoted by a U.N. maritime agency. Iran has threatened vessels using the path, which runs along the coast of Oman.
The opening of an alternative passage through the vital waterway would relieve pressure on the world economy and remove Iran’s main source of leverage in ongoing peace talks with the United States.
U.S. Secretary of State Marco Rubio, on a visit to the Gulf to reassure American allies, said Washington was committed to the new route.
Traffic through the strait has increased but is still well below prewar levels. Oil on June 25 briefly dipped below its last prewar price of just under $73 per barrel, a sign that the market believes the situation is improving.
The two sides are still debating terms of an interim peace deal — from getting ships through the narrow mouth of the Persian Gulf to the future of Iran’s stockpile of highly enriched uranium.

Under the memorandum of understanding signed last week, the U.S. and Iran agreed to a 60-day period to iron out the details. As talks are held behind closed doors, U.S. President Donald Trump and Iranian leaders have seemed to negotiate in public, trading threats and claiming concessions the other side denies.
The flare-up of fighting in Lebanon between Israel and Iranian-backed Hezbollah militants has meanwhile threatened the wider truce. Israel's first airstrike on Lebanon since a ceasefire took effect over the weekend killed two people on June 24, according to Lebanon's state-run news agency.
More Ships Are Passing Through the Strait
The oil tankers, led by the Stoic Warrior vessel, sailed along the coast of the United Arab Emirates and then Oman early June 25, passing by Oman's Musandam Peninsula fairly close to the shore. The route was laid out by Oman and the International Maritime Organization, a U.N. agency.
North of the route is the Traffic Separation Scheme corridor, in the center of the strait, where ships had moved through freely before the war, transporting about a fifth of all the world’s oil and natural gas.
Iran said it mined that passage after the U.S. and Israel attacked it on Feb. 28, and at least one mine has been sighted there.
Though some ships had been getting out of the strait, with U.S. military support, the U.N. agency's effort is the latest to free trapped vessels. The shipping company Maersk said its containership, the Maersk Baltimore, and another chartered vessel had also made it out of the strait on June 25.
Last week, 125 vessels crossed the strait, up from 33 the week before, according to marine data and analysis firm Lloyd’s List Intelligence.
According to S&P Global, June 24 saw 78 transits, the most since the war began. Among the vessels were 10 crude oil tankers, including five outbound large carriers that can carry up to 2 million barrels of oil.
Still, that daily total is below the average of 130 or more from before the war.
“Opportunistic operators — and there are many of them — emboldened by the lower transit risk, or at least the perceived lower transit risk, have begun chasing the backlog of trapped cargoes that built up during the conflict,” said Richard Meade, editor in chief at Lloyd’s List.
Iran Says New Route Is ‘Unacceptable’
The naval arm of the Revolutionary Guard, apparently reacting to the new shipping route and increased traffic, issued a warning June 25, carried by Iran's state-run IRNA news agency.

It said the new route was established “without notice or coordination with the Islamic Republic of Iran,” calling it “unacceptable and completely dangerous.”
“The only authorized route for passing through the Strait of Hormuz is the one declared by the Islamic Republic of Iran,” the Iranian force said. “Vessel traffic outside these routes is extremely dangerous and prohibited.”
“Violators will be dealt with,” it added, without elaborating.
There were no immediate reports of any incidents in the strait. On June 24, however, the Guard threatened one tanker over the radio, with a soldier warning “you are in range of my missiles and maybe (I) fire on you,” according to the private security firm Ambrey.
Rubio Says U.S. Will Ensure No Tolls

Those countries, including major energy producers reliant on the Strait of Hormuz for exports, came under attack by Iran after the start of the war.
“There is no part in this deal that’s undertaken that in any way undermines the security, the stability or the prosperity of any of our partners in the Gulf region,” Rubio said at the meeting in Bahrain, home to the U.S. Navy's 5th Fleet.
He later told journalists the U.S. and Gulf allies would ensure there would be no fees charged on ships moving through the strait.
He also criticized Iran's hard-liners for going “on their official media and making all kinds of pronouncements” that he described as not true.
He said the U.S. wanted to make sure the Oman route continued for ships to transit the strait. “If that stops, then we’re going to have a problem,” Rubio said.
The GCC countries have expressed reservations about the limitation of the U.S.-Iran deal signed last week, including conflicting claims over the strait and the fact that the memorandum of understanding does not specifically cover Iran’s nuclear or ballistic missile programs.
Bahrain’s Foreign Minister Abdullatif bin Rashid al-Zayani thanked the U.S. for its support, saying that because of the agreement, “today we see a glimmer of hope for our region” but stressed that it was “critically important that Iran adheres to its obligations.”
Lebanon Remains a Flashpoint
Israel’s military said on June 25 that a reservist soldier was killed and another hurt in southern Lebanon, where troops are occupying swaths of the country.

At least 37 soldiers have been killed in Lebanon or northern Israel during the fighting, as well as one civilian defense contractor. Two civilians in northern Israel have also been killed.
Over 4,000 people in Lebanon have been killed in Israeli strikes since the latest Israel-Hezbollah war began in March, two days after the Iran war started and when the Lebanese militant group fired at Israel.
