How a Houthi blockade in the Red Sea tightens Iran's grip on global energy supplies

Summary

This is why it matters and what it means for the Iran war and the global energy crisis: HOW BIG IS THE RISK TO GLOBAL ENERGY MARKETS? It is not clear how the Houthis would carry out a maritime blockade of Saudi Arabia, its northern neighbour along the Red Sea coast, or whether it would include a return to attacks on shipping. Also read: Yemen's Houthis announce a maritime embargo against Saudi Arabia Yemen sits on the Bab el-Mandeb strait - the southern gateway to the Red Sea - and closing that would open up a new front in the energy crisis and Iran's overarching conflict with the U.S. With Hormuz already disrupted, the Red Sea has become a critical alternative outlet for Gulf oil and other products. A serious disruption would mean both of the Middle East's major oil export routes are shut simultaneously. Iran's partial blockade of the Strait of Hormuz after Israel and the U.S. attacked it on February 28 disrupted most oil and other exports from the Gulf, raising prices and delivering a global energy shock. Saudi Arabia responded by diverting more than 70% of its normal daily crude exports to the Red Sea port of Yanbu. Ships from Yanbu bound for Europe go north through the Suez Canal. Those heading to Asia go south through Bab el-Mandeb. Shipments from Yanbu averaged 4 million barrels per day in recent weeks according to data from Kpler and Signal Ocean, up from around 973,000 bpd a year earlier. Total petroleum volumes transiting Bab el-Mandeb amounted to 7.4 million bpd in June, or about 7% of global oil output, according to Kpler data, up from 4.2 million bpd last year. That has provided a lifeline for the energy market, helping to keep down global oil prices. Saudi Arabia is considering an expansion of its crude oil pipeline to the Red Sea coast, Reuters reported last week. When the Houthis launched attacks on Red Sea shipping in November 2023, Gulf oil exports were flowing freely. WHO ARE THE HOUTHIS AND ARE THEY CLOSING RED SEA ENERGY ROUTES ON BEHALF OF IRAN? The Houthis emerged as a military, political and religious movement in north Yemen in the 1990s, fighting guerrilla wars against the government in Sanaa. They have been in a civil war against the Saudi-backed, internationally recognised, government for more than a decade and have attacked Gulf neighbours with missiles and drones. However, a 2022 truce between the country's warring sides largely held until last week, when Yemen's internationally recognised government said it had struck Sanaa airport to stop an Iranian plane landing. The Houthis said Saudi Arabia was responsible and in response fired missiles at Abha airport in the kingdom's mountainous southwest. A senior Houthi official, politburo member Mohammad al-Farah, then warned in an interview on Iran's Press TV website that if the situation kept escalating, Bab el-Mandeb would be closed. Iran champions the Houthis as part of its regional "Axis of Resistance", which includes Lebanon's Hezbollah and Iraqi Shi'ite militias, though its ties with the Yemeni movement are less clear than with those other groups. The Houthis do not recognise Iran's supreme leader as their ultimate religious authority in the same way Hezbollah and the Iraqi groups do. Their motivations are mainly domestic, though the group is ideologically aligned with Iran. The U.S. says Iran has armed, funded and trained the Houthis with help from Hezbollah. The Houthis deny being an Iranian proxy and say they develop their own weapons. It is not clear how far the group's stance on Bab el-Mandeb and the Red Sea stems from its own strategic priorities or is being made on Iran's behalf. WHAT HAPPENED WHEN THE HOUTHIS ATTACKED RED SEA SHIPS BEFORE? After the October 7, 2023, Hamas attack on Israel, and Israel's devastating campaign in Gaza, the Houthis began firing at Israel and on shipping in the Red Sea, saying they were doing so in support of Palestinians. Also read: Why the Red Sea remains one of the world's most dangerous shipping routes The attacks severely disrupted global shipping, prompting Maersk, Hapag-Lloyd and other major companies to divert around Africa - a far longer, more expensive route. Red Sea traffic has not recovered since, with traffic through the Suez Canal down 52% in 2025 versus 2023 levels and at its lowest in at least 50 years, Suez Canal Authority data shows. A U.S.-led mission to restore free navigation in the Red Sea involved repeated strikes on Houthi targets and a defensive campaign that shot down hundreds of drones and missiles. But some Houthi attacks continued until last summer, only ending completely with the Gaza ceasefire in October. Last month the Houthis said they would ban ships linked to Israel from the Red Sea after Israel renewed military attacks on Iran. However, that threat was never acted on and shipping groups Maersk and Hapag-Lloyd are resuming some Red Sea routes that they had abandoned during the Houthi attacks last year, Maersk said this month. WHAT HAVE THEY DONE DURING THE LATEST IRAN WAR? While Hezbollah and the Iraqi groups joined the war early with rocket and drone fire after the first U.S. and Israeli strikes on Iran, the Houthis had been comparatively quiet. The group's leader Abdul Malik al-Houthi said on March 5: "Our fingers are on the trigger at any moment should developments warrant it". Iranian commanders have repeatedly warned that the Houthis could join the war. The Houthis launched a few missile and drone attacks on Israel in late March and early April. Revolutionary Guards Quds Force commander Esmaeil Qaani said on June 1 they could choke off the Red Sea. That may now have changed with their announcement of the blockade on Monday against what they called the "criminal" Saudi Arabia in retaliation for what they called the kingdom's siege of its ports and airports, including with last week's strike.

Another ship hit in Hormuz as Houthis add to regional risks A tanker has been struck by an unknown projectile northeast of Oman’s Limah, UK Maritime Trade Operations says on Tuesday - Hormuz was deserted on Jul 21, with no ships observed transiting, data shows.

PHOTO: REUTERS [SINGAPORE] Another tanker was attacked in the Strait of Hormuz as renewed hostilities empty the waterway, while a threat by Houthi rebels to blockade Saudi Arabia in the Red Sea heightened regional maritime risks. The Kaifan, an oil products tanker owned by Kuwait Oil Tanker, was the vessel attacked in the strait, according to security consultancy EOS Risk Group.

The ship was struck by an unknown projectile northeast of Oman’s Limah, UK Maritime Trade Operations said earlier on Tuesday (Jul 21), without naming the tanker. Kuwait Oil Tanker did not immediately respond to emailed requests for comment, and ship tracking data shows Kaifan last signalled its location more than a month ago near Sohar, Oman.

The attack on the Kuwaiti tanker follows strikes in recent days on vessels owned by Dynacom Tankers Management. Hormuz was deserted on Tuesday, with no ships observed transiting, data shows. Iran’s recent spate of attacks has focused on oil tankers shuttling through the strait along the Omani coast, often with their transponders turned off.

Earlier strikes have affected major operators such as South Korea’s Sinokor Group and Greece’s Dynacom, which have been instrumental in sustaining crude flows during much of the war with tankers sailing through Hormuz dark. In the week ended Jul 19, Hormuz crossings averaged seven tankers each day, compared with 16 per day a week earlier, said Rahul Kapoor, global head of shipping analytics and research for S&P Global Energy.

“Ship operators remain increasingly cautious, with risk tolerances continuing to be tested,” he said. An empty Sinokor supertanker, Plata Singapore, that was sailing towards the Gulf of Oman with the aim of reaching Saudi Arabia’s Ras Tanura in the Persian Gulf, deviated from its path on Sunday, according to ship tracking data.

The vessel is currently in the Arabian Sea. The South Korean company did not immediately respond to an emailed request for comment. The threat by Iran-backed Houthi militants to blockade Saudi Arabia’s maritime traffic has added another element of risk.

Shipowners with vessels seeking to transit the Red Sea were advised to review their affiliations with the kingdom, with at least one supertanker in nearby waters switching its broadcast to say that it belongs to the Indian government. The India-flagged supertanker, Desh Viraat, which is half-filled with crude from Fujairah, began sailing southwest earlier this week towards Bab el Mandeb in the Gulf of Aden, signalling it had armed guards onboard.

Soon after the Houthi threat on Monday, it switched that signal to “Govt. of India Await”, making clear that it has links to New Delhi. Desh Viraat’s owner, the Shipping Corporation of India, did not immediately respond to an emailed request for comment.

“Companies maintaining regular Saudi trade should consider their exposure elevated, particularly for vessels calling at Red Sea ports,” maritime risk company Marisks said in a note to clients late on Monday that was seen by Bloomberg News. Even though it remains to be seen whether the Houthis will carry through with their threat, “for shipowners, risks have heightened”, said Anoop Singh, global head of shipping research at Oil Brokerage.

Goldman Sachs has projected Brent crude averaging $80 per barrel in the fourth quarter and $75 in the following year, conditional on reduced Middle East tensions, while noting upside risks from potential shipping disruptions in the Strait of Hormuz or Red Sea.

Brent prices rose above $91 per barrel amid recent U.S.-Iran exchanges and Houthi threats to Saudi shipments before edging lower on Tuesday. A senior Iranian official told Reuters that mediators had proposed a 10-day ceasefire to preserve an interim agreement.

Opening summary: Iran claims attacks on strait of Hormuz ships amid fresh US strikes Welcome to our live coverage of the latest developments in the Middle East crisis. Iran attacked a tanker in the strait of Hormuz early on Tuesday, forcing its crew to abandon the ship, as Yemen’s Iran-backed Houthis announced they were imposing an immediate maritime blockade of Saudi Arabia in the Red Sea after the two sides traded fire last week for the first time in years.

A Houthi official said the Bab al-Mandeb strait – at the southern end of the Red Sea, through which about 12% of the world’s trade usually passes – would be closed to the Saudis in response to the kingdom’s “unjust blockade on Yemenis for over 10 years”.

Saudi Arabia said it would take “all necessary measures to protect its vessels in accordance with international law”. A 10 consecutive night of US airstrikes has not compelled Tehran to loosen its grip on the strait of Hormuz, a vital route for global energy supplies.

But even as Iran’s president said the country had returned “full-scale war”, the Iranian interior minister travelled to Pakistan – a key mediator in the conflict – for talks. In key developments: The latest US strikes came hours after Donald Trump said Iran would pay “many times over” for killing US soldiers after multiple service members were killed in action over the weekend.

A tanker came under attack early Tuesday in the Hormuz strait off Oman, forcing the crew to abandon the vessel, the British military’s United Kingdom Maritime Trade Operations centre said. Iran’s Revolutionary Guards claimed the attack as well as two other attacks on ships in the waterway on Monday.

The US military’s Central Command said its latest airstrikes were to “degrade” Iran’s ability to attack commercial shipping in the strait and included hitting military command centres and missile and drone launch sites. Iranian media reported strikes in parts of the country including Bandar Abbas, Tabriz and Bushehr, home to the country’s only operational civilian nuclear power.

Iran’s launched attacks in response against Bahrain, Kuwait and Jordan, which all host US forces. Oil prices softened after hitting their highest levels in more than a month in the previous session. Brent crude futures eased 0.4% to $88.87 a barrel by 0052 GMT on Tuesday while US West Texas Intermediate crude for September delivery was steady at $82.

47 a barrel. Democrats have seized on the deaths of three US troops killed in Iranian strikes to urge Trump to urgently reverse his resumption of the war with Iran amid widespread anxiety over climbing casualties. The Lebanese army began taking charge of security in three southern villages, the US said, as a deal to secure an Israeli withdrawal from southern Lebanon and the disarmament of Hezbollah faced its first test on the ground.

US forces struck the tanker Settebello in the Gulf of Oman on June 10, killing three Indian crew members when munitions hit the engine room and adjacent areas. Maritime tracking data indicate the vessel had transported Iranian oil under US sanctions for several years and conducted offshore transfers prior to the strike.

The US military described the action as a precision operation, while reports note the ship was stationary at the time.
