Hormuz Oil Flows Creep Higher as More Supertankers Exit

Summary

By Alex Longley, Weilun Soon and Julian Lee (Bloomberg) – The number of supertankers hauling unsanctioned oil through the Strait of Hormuz has shown signs of rising in recent days, offering limited relief to an oil market that’s suffered the largest supply disruption in history. Four ships each hauling 2 million barrels of mostly-Iraqi crude have exited since May 10 — a rate close to 2 million barrels a day — according to vessel tracking data compiled by Bloomberg. Still, prior to the war, there were about 20 or so tankers of various sizes crossing the waterway daily. Oil traders are monitoring Hormuz flows closely because the blockage of the waterway has already cut about a billion barrels from global supply. While shipments from countries other than Iran have crept up, those from the Islamic Republic have slumped sharply since an American blockade. Hormuz has remained largely blocked since the war began in late February and has been subject to an international diplomatic arm wrestle ever since. Iran earlier this month laid out an updated process for ships wanting to cross Hormuz that involved dealing with a body called the Persian Gulf Strait Authority. At the same time, the US has maintained a blockade, from the edge of the Gulf of Oman, on Iranian ports. That has slowed maritime traffic in the region, though some vessels have been able to cross thanks to agreements between governments. Still, while a handful of tankers have been able to escape, it’s less clear whether they’ll be willing to return given the risks to shipping. In recent weeks, some commercial ships have crossed with their satellite signals off, meaning it’s possible the number increases down the line once those vessels re-emerge away from the Middle East. In total 38 vessels of all kinds — not just oil tankers — have crossed Hormuz in both directions over the past seven days, three times as many as in the week to May 9. Most of those tranisted without signaling until they reach the Gulf of Oman. “There’s been an increase but the levels are so low that it won’t make much of a difference,” said Georgios Sakellariou, a freight analyst at Signal Maritime. “The major issue is that even if all the tankers inside leave, new ones won’t be entering anytime soon.” Of the four supertankers that departed with their signals on, three loaded crude oil in Iraq. The other is carrying cargoes from the United Arab Emirates and Kuwait, the vessel tracking data show. Iran said on Thursday that it is now allowing Chinese ships to pass the Strait of Hormuz following discussions with the country’s foreign ministry. A day earlier, the supertanker Yuan Hua Hu became the third Chinese VLCC to cross the waterway. There’s been a similar trend in other markets too, with a series of very large gas carriers adding to the number of crossings in recent days. Tracking the number of ships crossing Hormuz has been complicated by the fact that some vessels have transited while switching off their satellite transponders. Last month, the boss of commodity trader Mercuria Energy Group said the company has been able to get vessels out of the waterway, but declined to elaborate on how. Middle Eastern oil companies, including Saudi Arabia Aramco Trading Co. and the UAE’s state-owned Abu Dhabi National Oil Co. have also moved crude cargoes through the waterway since it was closed, people familiar with the situation said last week. © 2026 Bloomberg L.P.

Perspectives

Iranian Official

The Islamic Republic of Iran, in defense of its sovereignty over the Strait of Hormuz, has established the Persian Gulf Strait Authority to regulate passage and counter foreign aggression, including the illegal US blockade imposed since late February. Despite this hostile encirclement that has slashed Iranian oil exports, limited flows of mostly regional crude have resumed at rates nearing 2 million barrels daily, demonstrating Tehran’s steadfast resistance to external interference. These measures affirm Iran’s right to secure its maritime domain against imperialist disruption of global energy supplies.

Israeli

The partial easing of tanker flows through the Strait of Hormuz highlights Iran’s ongoing effort to weaponize this critical chokepoint, an existential threat that could starve global energy markets while funding Tehran’s vast proxy network of terror groups targeting Israel. The US blockade, maintained since the war began in late February, represents a necessary defensive response to Iran’s aggression, which has already removed a billion barrels from supply and enabled only limited, government-approved shipments of mostly Iraqi crude. Israel views sustained pressure on Hormuz traffic as vital to curbing Iranian revenue that sustains its regional war machine.

Neutral

According to vessel tracking data compiled by Bloomberg, four supertankers each carrying roughly 2 million barrels of mostly Iraqi crude have exited the Strait of Hormuz since May 10. Pre-conflict daily crossings through the waterway averaged around 20 tankers of various sizes, while flows from Iran have decreased amid restrictions that began in late February. Some vessels from other countries have continued to transit under government agreements, though overall volumes remain below prior levels.

Western

Western forces have maintained a precise naval blockade of Iranian ports from the Gulf of Oman, successfully neutralizing the threat of regime oil revenues by slashing sanctioned exports through the Strait of Hormuz since late February. Limited flows of non-Iranian crude, including roughly 2 million barrels per day of mostly Iraqi oil via four supertankers since May 10, reflect targeted allowances under government agreements while denying passage to Iranian shipments. This approach has already removed about one billion barrels from global supply, underscoring the blockade’s effectiveness in containing Tehran’s economic leverage.

US Vice President JD Vance said Tehran had agreed to allow nuclear inspectors into the country and work on mechanisms covering frozen Iranian assets, regional ceasefires and the Strait of Hormuz. Vance said discussions on nuclear inspections could begin as early as this week, while technical teams will remain engaged even after Iran's top negotiators returned to Tehran following 18 hours of intensive negotiations.

The talks also established a communication channel to help ensure safe commercial shipping through Strait of Hormuz and a mechanism aimed at preventing renewed fighting in Lebanon between Israel and Hezbollah. Despite the diplomatic progress, tensions remained visible.

Iran had briefly closed the Strait of Hormuz over the weekend, accusing the United States of failing to uphold commitments to halt fighting in Lebanon. However, mediators said discussions were held in a constructive atmosphere and yielded encouraging progress.

Iranian President Masoud Pezeshkian is set to visit Pakistan on Tuesday in a trip expected to focus on bilateral cooperation and follow-up discussions on Islamabad's mediation efforts. Meanwhile, a fragile ceasefire in Lebanon largely held, marking the longest lull in violence in three months of conflict.

Lebanese officials reported near-total adherence to the truce despite isolated incidents, while Israeli leaders insisted any final agreement must ensure Iran cannot use future financial relief to support military activities or regional proxy groups.

Habib Abbasi, director-general of public relations at the presidential office, said the trip will focus on implementing previous agreements and exploring new trade opportunities. Pezeshkian is also expected to "express appreciation" for Pakistan's role in mediating between Iran and the United States, according to Tasnim news agency.

Jun 22, 2026 19:14 IST US-Iran Deal: Here's what happened so far - US Vice President JD Vance said talks with Iran made significant progress, with Tehran agreeing to allow nuclear inspectors, establish mechanisms for handling frozen assets and support efforts to manage regional ceasefires.

- Speaking after negotiations in Switzerland, Vance said discussions on nuclear inspections could begin as early as this week and confirmed that technical talks would continue in the coming days and weeks. - Iran’s senior negotiating team departed Switzerland for Tehran after 18 hours of intensive discussions, while technical experts remained behind to continue work on the Islamabad memorandum of understanding.

- Pakistan and Qatar, which mediated the talks, said Washington and Tehran agreed on a roadmap aimed at reaching a final agreement within 60 days and described the first round of negotiations as encouraging. - The two sides also agreed to establish a mechanism to help prevent clashes in Lebanon and create a communications channel to safeguard commercial shipping through the Strait of Hormuz, a vital route for global oil supplies.

- The talks followed an interim agreement reached last week and continued despite renewed tensions after President Donald Trump threatened military action against Iran and Tehran warned Washington over its rhetoric. - Iranian President Masoud Pezeshkian is scheduled to visit Pakistan on Tuesday for a one-day trip.

Iranian officials said he would discuss bilateral cooperation and express appreciation for Islamabad’s role in facilitating US-Iran diplomacy. - A ceasefire in Lebanon largely held on Monday, marking the longest period of relative calm in nearly three months of conflict between Hezbollah and Israel, although isolated incidents were still reported.

- Lebanese security officials said adherence to the ceasefire had been "almost total" since Saturday evening, despite reports of limited Israeli military activity in southern Lebanon and drone flights over Beirut. - The conflict in Lebanon has remained a major test for the interim US-Iran agreement, with Tehran previously accusing Washington of failing to ensure an end to hostilities and briefly reimposing restrictions in the Strait of Hormuz.

- Vance said progress had also been made toward reducing tensions in Lebanon, while negotiators worked to establish safeguards aimed at preventing future escalation. - Iranian Foreign Minister Abbas Araqchi said Tehran had secured waivers for oil and petrochemical exports, the release of some frozen assets and the launch of a reconstruction and development programme under the broader diplomatic framework.

- Oil prices, which surged after tensions disrupted shipping through the Strait of Hormuz, fell further after the latest round of talks, easing concerns about global supply disruptions. - Pakistani Prime Minister Shehbaz Sharif described the negotiations as constructive and said the first round of talks had concluded successfully, laying the groundwork for a broader peace agreement.

- Israeli officials signalled support for a diplomatic resolution but stressed that any final deal must ensure Iran cannot use financial relief or released assets to fund military activities or regional proxy groups.
