Hormuz Crisis “Only Going to Get More Horrific Before It Gets Any Better”: Prof. Laleh Khalili

Summary

Media Options Guests - Laleh Khaliliprofessor of Gulf studies at the University of Exeter. Amid the ongoing crisis in the Strait of Hormuz, we speak with Laleh Khalili, a professor of Gulf studies who researches the shipping and logistics industry and its impact on the global economy. The U.S. implemented a naval blockade on Iran earlier this week, which Khalili says could lead to its military “firing on ships that it assumes are Iranian or carrying oil from Iran or other cargo to Iran.” Iran, in response, could “interpret this as a belligerent action,” ending the fragile ceasefire agreed to by both parties. “Iran is going to defend itself against this imperial imposition, and how it’s going to do that remains to be seen.” Meanwhile, explains Khalili, shipping disruptions in the Gulf have affected the supply chains of key resources including oil, aluminum, helium and fertilizer. “Transportation costs are going to be higher, so food prices are going to be higher; people’s MRIs are going to be scheduled out by six months … semiconductor manufacturing is going to be affected,” Khalili says. “The crisis is only going to get more horrific before it gets any better. ” Transcript NERMEEN SHAIKH: Iran’s military says it will begin disrupting shipping in the Sea of Oman and the Red Sea if the United States does not end its naval blockade of Iranian ports. Iran’s threat of escalation came as U.S. Central Command said U.S. forces have completely halted maritime trade to and from Iran, with at least 10 vessels forced to turn around. At a press conference today, Defense Secretary Pete Hegseth said the U.S. plans to enforce the blockade. Iran effectively closed the Strait of Hormuz in early March, disrupting global oil and trade markets. On Wednesday, White House Press Secretary Karoline Leavitt was questioned about the Navy blockade of Iranian ports. LIBBEY DEAN: On Iran, is there a timeline for how long this blockade is going to remain in place in the Strait of Hormuz by the United States that President Trump has voiced to you or that you’ve heard among officials? PRESS SECRETARY KAROLINE LEAVITT: Sure. I will never set timelines on behalf of the president of the United States. But with respect to the blockade, as you know, it has been fully implemented, and it’s being enforced against vessels of all nations entering or departing Iranian ports. I want to make that point clear. I’ve seen some misreporting on that, as well. This includes all Iranian ports on the Arabian Gulf and the Gulf of Oman. And our U.S. forces in the region are supporting the freedom of navigation for vessels that are transiting the strait to and from non-Iranian ports. So, I know some in the press were confused about that. We are supporting the freedom of navigation, just not with respect to any tanker or vessel that would benefit the economy of Iran as these negotiations continue. AMY GOODMAN: Karoline Leavitt went on to say that the White House is optimistic about continuing negotiations between the U.S. and Iran. On Wednesday, a high-level Pakistani delegation traveled to Tehran to lay the groundwork for a possible second round of talks. We go now to London, where we’re joined by Laleh Khalili. She’s a professor of Gulf studies at the University of Exeter and author of several books, including Extractive Capitalism: How Commodities and Cronyism Drive the Global Economy, as well as Sinews of War and Trade: Shipping and Capitalism in the Arabian Peninsula. I can’t think of any time that your work was more relevant than now, Professor. Let’s start off with this naval blockade of Iranian ports entering its fourth day. The blockade is being enforced, according to CENTCOM, by 10,000 U.S. troops, over a dozen warships, dozens of aircraft. Can you explain exactly what’s happening and, for the geographically challenged, the difference between the Strait of Hormuz, the Persian Gulf, and how it’s extending beyond to the Red Sea and the Sea of Oman? LALEH KHALILI: OK. Thank you very much for having me on. And yes, sadly, this is a terrible way for my area of expertise to actually be of relevance. So, first, the geography of the area. The Persian or Arabian Gulf sits between Iran on the north, a sliver of Iraq on the west, and then the various countries that are known as emirates or kingdoms of the Gulf — Kuwait, Bahrain, Saudi Arabia, Qatar and the United Arab Emirates — around the southern shore of the Persian Gulf. At the narrowest bit where the Persian Gulf meets the Gulf of Oman on the other side, that’s the Strait of Hormuz, which, depending on how you measure it, it’s around 25 to 30 nautical miles. So, the Gulf — the Strait of Hormuz lies in the north — between Iran in the north and the Musandam Peninsula, which is an extension of Oman, in the south. So, in fact, the water of the Strait of Hormuz is divided between those. There is no high seas. There is — this is territorial waters divided evenly between the two countries. So, that’s the first thing. The second thing is that, of course, the whole Iran basically lies on the entire northern shore of the Persian Gulf, but also the Gulf of Oman. So it does have capacities. In fact, one of Iran’s big ports, in which India invested, Chabahar, is in the eastern part of Iran in the northern shore of the Gulf of Oman. Red Sea is on the other — the Red Sea is on the other side of the Arabian Peninsula, so the Red Sea lies on the western shore of Saudi Arabia. And the way that Iran can disrupt trade in that, in the Red Sea, is through firing missiles, for example, as it has done already, to the port of Yanbu, which is a oil-lifting port for Saudi Arabia on the Red Sea, but also through possibly having its ally, the Ansar Allah of Yemen, which are otherwise also known as the Houthis, disrupting trade there, as they did during the Israeli genocide of Palestinians in Gaza. But there are a couple of things about that blockade question that I think is really important to note. First of all, the U.S. claims to have stopped completely and totally the trade of oil out of Iran, or indeed has blockaded any kind of ships going to or from Iran. In fact, reporting from shipping companies that actually track this stuff comes back that in the four days since the blockade has started, somewhere between 14 to 15 ships have gone through the Strait of Hormuz, at least half of them to Iran. And the way that they have done so is either through routes that obviously the U.S. is incapable of, or not particularly good at, policing, through spoofing their Automatic Identification System — spoofing is this process where the Automatic Identification System is essentially presented as somebody else’s ID system, indicating a different country or different flag country for the ship and — or ships have gone dark, which is something that happens all the time. In fact, when I traveled on a freighter many, many years ago, 10, 11 years ago, one of the things that was most striking when going through the Red Sea, the Gulf of Aden and indeed the Persian Gulf, was the extent to which warships, particularly U.S. or the EU warships, actually turned off their AIS and went dark. So, this is a practice, although a lot of people like to present it as some kind of a nefarious thing. If we are going to think of it as nefarious, in fact, a lot of ships take take part in this practice of going dark, including especially the United States. In fact, this, as in the case of U.S. naval ships, has resulted in all sorts of — in all sorts of problems, collisions, indeed, with U.S. Navy ships. Now, in terms of the actual blockade and the effects it’s having, I was just looking at the Bloomberg today, and forgive me as I read this out, because it was really striking to me. Bloomberg, which is, of course, one of the most reliable financial reporting sites anywhere in the world, reports that we are “moving from short-term jolt to a long-term shock as the largest supply disruption in the history of the global oil market takes place.” So, this is what’s happening. And obviously the blockade continues, because before the war, before the U.S. and Israeli war on Iran started on the 28th of February, somewhere between 140 to 170 ships a day were crossing the Strait of Hormuz; now it’s only 14 to 15. And one of the things that this has meant is that about 10 million barrels per day of oil supply has been lost. This includes — although, of course, the primary people being punished by this shortage of oil are the economies in Asia, in fact, it actually also affects the United States, because some of the last ships that left the Persian Gulf before the war started were actually delivering their supplies now, so we are going to see the effects of the blockade in the coming week or two. And apparently one of these ships actually arrived in California, because, unlike the rest of the United States, California actually does receive oil from the Middle East, and its refineries use a medium-sour oil, a kind of a medium grade, and “sour” meaning high sulfur, a kind of oil that comes specifically from the Middle East. So, the effects of this are, of course, being felt incredibly widely. Another really striking statistic was that an actual real-world barrel of oil was sold in Sri Lanka at more than $280 a barrel. That is double what the price is going elsewhere in the world. And so, the effects of this are incredibly, incredibly striking. What the blockade might mean, of course, is that the U.S. will start firing on ships that it assumes are Iranian or carrying oil from Iran or other cargo to Iran. But, of course, if it does so within the context of the ceasefire, it is violating the ceasefire. And if it does so outside the context of ceasefire, Iran can interpret this as a belligerent action, because, of course, a blockade is exactly that, particularly as it is blockading Iran in its territorial waters. So, the state that we’re in is that, of course, we’re not getting any reliable or credible kind of reporting from the Trump administration whatsoever. And the state of play in the region, of course, is that Iran is going to defend itself against this imperial imposition, and how it’s going to do that remains to be seen. NERMEEN SHAIKH: Laleh, as you mentioned, despite the fact that the U.S. says that its blockade is entirely effective and no ships are getting through, at least 14 to 15 have got through, including several Iranian ships. Now, The Washington Post reported just yesterday that more troops are expected — U.S. troops are expected to arrive in the region, an additional 6,000 to arrive soon and 4,000 to arrive at the end of the month. I mean, if you could say something about what would make and whether those troops — and obviously this is speculation — whether they might help to impose a more total blockade, or, you know, where you see this going? LALEH KHALILI: It’s really difficult to say, again, in part because reporting on this war has been so drastically narrow and that there’s so much misinformation coming from the United States and its allies in the region, both the Arab Gulf emirates, as well as Israel. And, of course, there is little reporting that comes from the Iranian side that is completely and totally verifiable. There’s an interest by everybody to sort of not give the whole picture. In the case of this troops arriving, I wonder how many of those troops that are arriving were the troops that were on the way when, a couple of weeks ago, the U.S. declared that there was going to be airborne troops deployed to Iran. There’s also some question for me, and it’s not a question that only I’m asking: I’m really curious as to why the pilot that was downed, the two pilots that were ostensibly rescued a couple of weeks ago, have not appeared on any television shows — they have not been paraded around as such things are customary — and, indeed, whether or not the story of a pilot rescue was actually cover for a trial run of taking away Iran’s uranium near Isfahan. So, to me, it’s unclear how the arrival even of another 15,000 or 20,000 troops are going to accomplish this, because in addition to, obviously, the troops arriving, you’re going to need to have equipment arriving, as well. You’re going to have to have more ships, etc. And so, this means repositioning, basically, the U.S. naval posture, not just in the Gulf, but also elsewhere in the world, as it shifts its ships to the region. This also indicates, to some extent, that perhaps what the aim of the Trump administration is is to return to hostilities after the end of the ceasefire period. The problem with, of course, this is that there is so much that the sort of the shocks that we saw in the first couple of weeks of the war are going to only accelerate in a number of different areas. So, obviously, the, as I said, about 10 million barrels per day of oil has been taken out of the market. But in addition to that, there was reporting today that there’s going to be an incredible shortage of aluminum, as aluminum smelters in the Gulf have either been hit — and in one case, there was a very dramatically describing instance where an aluminum smelter in Abu Dhabi was hit, and the actual molten aluminum froze in the pipes, making — I mean, they would have to basically replace a lot of the equipment in those. With aluminum, actually, prices being at a four-year high, higher than it has ever been since the Russian war on Ukraine, there’s also China has just banned export of sulfuric acid, which is really incredibly necessary for the production both of fertilizer, but also very more — much more significantly, in the manufacturing of semiconductors. Helium reserves are down massively, because, of course, Qatar was one of the world’s biggest — Ras Laffan plant was the world’s single largest producer of helium, although the U.S. is the largest country producer of helium. And with helium being — the helium amount being down, semiconductor manufacturers, including chip makers for companies like, for example, Nvidia are concerned, because, of course, helium goes to MRI machines and to chip makers. And, of course, given the way that the market is so overblown and there’s such a big bubble around AI, there’s probably going to be a shift from using helium for MRI machines to towards the chip makers, because, of course, that’s going to be, you know, out to the profits in the pockets of the tech bros. And what that indicates, of course, is that this is going to also hit people really hard. So, the effect of what the war is going to be is going to actually be felt even more strongly in the coming weeks, in both inflationary terms, in the inflation in the price of petrol at the petrol pump, but also in other ways, because, of course, transportation costs are going to be higher, so food prices are going to be higher, when people’s MRIs are going to be scheduled out by six months or some such, when semiconductor manufacturing is going to be affected. This is going to be quite significant. The other factor in all of this, of course, is the question of insurance. And a lot of insurance providers have actually either suspended providing insurance to any ships in the whole of the Middle East region, the whole of the sort of region surrounding the Arabian Peninsula, or have increased the war risk premium incredibly, in a very kind of dramatic sort of way. Now, the U.S. has kind of promised, since the beginning of the war, that it is going to cover the insurance via kind of a backstop for insurance. The U.S. International Development Finance Corporation has talked about how it is moving toward sort of getting — working with private insurance providers to insure about $40 billion worth of ships. But that’s actually like a drop in the bucket, because in the early part of the war, JPMorgan estimated that the actual amount needed for ships that are in the Gulf, as a minimum, is $352 billion, so this would be 10% of the amount of ships. So, again, this combination of both the market, the logic of commercial risk, on the one hand, but, on the other hand, the fact that Iran poses a credible threat to ships in the Strait of Hormuz, in the Gulf of Oman, and both directly and via its allies and Ansar Allah in the Red Sea, means that I actually think that the crisis is only going to get kind of more horrific before it gets any better. NERMEEN SHAIKH: Laleh Khalili, thanks so much for joining us, professor of Gulf studies at the University of Exeter and author of several books, including Extractive Capitalism: How Commodities and Cronyism Drive the Global Economy and Sinews of War and Trade: Shipping and Capitalism in the Arabian Peninsula. When we come back, the ongoing civil war in Sudan enters its fourth year, creating what the United Nations calls the world’s worst humanitarian crisis. Stay with us.

DUBAI, United Arab Emirates (AP) — Iran attacked a tanker in the Strait of Hormuz early Tuesday, forcing its crew to abandon the ship, while the United States conducted yet another round of airstrikes targeting the Islamic Republic as they struggle over control of the key waterway.

The 10 consecutive nights of U.S. airstrikes haven’t compelled Tehran to loosen its grip on the strait, through which about a fifth of all crude oil and natural gas traded once passed in peacetime. Even as the U.S. and Iran inch closer to all-out war again, Iran’s interior minister traveled to Pakistan, a key mediator in the conflict, for talks.

However, it remains unclear just what new deal could be reached to end the fighting. The interim deal signed last month that was meant to end the fighting has crumbled. Shipping through the Strait of Hormuz has largely stalled. And as fighting intensifies, both sides have targeted civilian infrastructure relied on by millions of people.

“Iran and groups supportive of Iran may target other U.S. interests overseas or at locations associated with the United States and Americans throughout the world,” the U.S. State Department said in a new warning to Americans. The escalation has pushed oil prices higher in recent weeks.

Benchmark Brent crude traded Tuesday above $88 a barrel and regular gasoline in the U.S. climbed to an average of $4 a gallon, keeping pressure on Americans’ wallets ahead of midterm elections this fall. Meanwhile, the U.S. military identified two soldiers who were killed in Jordan in attacks that left a third person missing.

Separately, the military confirmed another death in Iraq on Saturday during the “controlled detonation” of a downed Iranian drone. President Donald Trump took to social media on Monday to warn that “Every time Iran kills an American Soldier they will pay for that killing many times over!

” Trump was planning to attend a ceremony on Tuesday evening at Dover Air Force Base, where at least one service member’s remains were due to arrive. US strikes come as ships attacked The U.S. military’s Central Command said Tuesday it targeted “Iranian military command centers, maritime capabilities, missile and drone launch sites and air defense systems.

” It released more footage of bombings that targeted sites in Iran. “American forces remain postured and prepared to hold Iran accountable for unwarranted aggression toward civilian mariners seeking to freely and openly transit the strait,” the command said.

Iranian state media reported that explosions were heard in Fars, Hormozgan, Ilam, Kerman and Sistan and Baluchistan provinces. However, traffic through the strait has slowed to a crawl during the latest violence. Lloyd's List Intelligence said only three ships transited the strait on Sunday.

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

The route around Oman has been the one the U.S. military has encouraged ships to travel to avoid Iran’s control. The UKMTO separately reported Tuesday that another previously unknown attack on a ship took place early the previous day. Tehran also hit U.

S.-allied countries throughout the Middle East. Jordan military's said Tuesday that Iran targeted it with five drones and three missiles, all of which were shot down. Bahrain sounded its missile alert sirens Tuesday afternoon as another Iranian barrage targeted the island kingdom, which is home to the U.

S. Navy's 5th Fleet. Nearly 100 US injuries since early July The Pentagon’s chief spokesperson said nearly 100 U.S. service members have been injured since the U.S. restarted strikes on July 7, and 96% of them have returned to duty.

“The vast majority of injuries experienced were minor concussions,” Sean Parnell posted Monday on X in response to a New York Times report that the Pentagon has withheld information about troop injuries from Iranian strikes. He denied that the Pentagon was hiding data about injuries.

However, the Defense Casualty Analysis System, the military’s clearinghouse for reporting deaths and injuries in conflict, has not been updated as of Monday night with the latest attacks. Yemen rebels threaten attacks on other Mideast waterway Yemen’s Houthi rebels announced a maritime embargo against Saudi Arabia on Monday.

The Houthis, who are backed by Iran, said they would block shipping between the Red Sea and the Gulf of Aden by targeting the Bab el-Mandeb, a maritime chokepoint like the Strait of Hormuz, in response to an attack on Sanaa International Airport last week that they blamed on Saudi Arabia.

With the Strait of Hormuz blocked, Saudi Arabia has been relying on a pipeline to the Red Sea to get millions of barrels of oil out to market. The Houthis earlier demonstrated their ability to disrupt shipping there when they targeted ships for months over the Israel-Hamas war in Gaza, with over 100 vessels attacked.

Saudi Arabia’s military said it would keep the waterway open. “All Houthi threats against transiting vessels will be dealt with swiftly and firmly, as such threats are a blatant violation of international law and fall under acts of maritime piracy,” said Maj.

Gen, Turki al-Malki, a Saudi military spokesman. A glimmer of hope for diplomacy Pakistan has intensified diplomatic efforts in recent days to resuscitate the interim deal. Iranian Interior Minister Eskandar Momeni arrived in Islamabad on Monday for two days of talks with Prime Minister Shehbaz Sharif and others.

On Sunday, U.S. Secretary of State Marco Rubio told reporters that the U.S. is still open to negotiating with Iran but that “it has to be real.” “If the door opens to diplomacy — if the guys that want to do something productive for Iran win and take control of that system, or take control of the negotiations — that’ll be a very positive development,” Rubio said.

“That’s not where we are tonight, unfortunately.” Iranian authorities on Sunday said at least 50 people have been killed and 517 wounded in the latest rounds of U.S. strikes. Since the war began on Feb. 28, 17 U.S. service members have been killed.

US Secretary of War Pete Hegseth posted social media images showing damage to a maritime control tower at Iran’s Chabahar port following reported US military strikes, accompanied by the caption “Iran does not control the Strait of Hormuz.” India’s Ministry of External Affairs stated that the Shahid Beheshti terminal operated by India at the port sustained no damage.

The ministry reiterated its position that civilian infrastructure should not be targeted during conflicts.

U.S. strikes Iran and Houthis threaten Saudi Arabia shipping as mediators push 10-day ceasefire - The U.S. has carried out its tenth consecutive evening of attacks against Iran. - Iran attacked a tanker in the Strait of Hormuz early Tuesday, while Houthi militants in Yemen declared a maritime embargo against Saudi Arabia.

- Rystad Energy has warned about the risk of a significant rebound in oil prices. The U.S. completed a fresh round of strikes against Iran on Monday evening as Yemen's Iran-backed Houthis threatened to impose a naval blockade on Saudi Arabia, potentially opening a new front in the Middle East conflict.

The latest cycle of tit-for-tat strikes comes amid reports that regional mediators have presented Washington and Tehran with a proposal for a 10-day ceasefire, a pitch that could put last month's Memorandum of Understanding back on track. The U.S. Central Command said overnight that it had carried out another round of strikes on Iran at 9 p.

m. ET on Monday. "U.S. forces struck Iranian military command centers, maritime capabilities, missile and drone launch sites, and air defense systems to degrade Iran's ability to continue attacking commercial vessels flowing through the Strait of Hormuz," Centcom said in a statement.

It added that commercial vessel transits through the strategically vital waterway were continuing. Centcom forces, the statement said, had facilitated the transit of around 900 commercial vessels and 450 million barrels of crude oil through the strait since early May.

Iran, meanwhile, attacked a tanker in the Strait of Hormuz early Tuesday, forcing its crew to abandon the vessel as it seeks to tighten its control over the waterway, one that typically handles around 20% of the world's oil traffic. Houthi militants in Yemen on Monday declared a maritime embargo against Saudi Arabia effective immediately, a move that could substantially threaten Middle East oil supplies.

The Houthis have repeatedly threatened to close the Bab el-Mandeb Strait during the U.S.-Iran war. The strait is a choke point for commercial ship traffic that connects the Red Sea to the Gulf of Aden and global markets. The militants, in a statement carried by state news, accused the Saudis of laying an "aggressive siege" against them.

Tensions escalated last week after they claimed that Riyadh had bombed Sanaa International Airport. The Saudi-led coalition in Yemen said that it would respond to the Houthis naval blockade with force, reportedly describing such threats as "a blatant violation of international law.

" 10-day ceasefire 'won't be an easy task' Oil prices rose briefly on news of the Houthi statement but later pared gains as energy market participants closely monitored the prospect of a diplomatic breakthrough. International benchmark Brent crude futures with September delivery were last seen trading 0.

5% lower at $88.77 per barrel, having surpassed $90 in the previous session. U.S. West Texas Intermediate futures with August delivery, meanwhile, stood 0.4% lower at $82.88. Strategists at ING said there's some hope of de-escalation between the U.S.

and Iran given the reports that mediators are proposing a 10-day ceasefire. "This won't be an easy task," ING's Warren Patterson and Ewa Manthey said in a research note published Tuesday. "Large divisions remain between the US and Iran. And President Trump said the US would retaliate following the deaths of several American troops," they added.

In a post on Truth Social on Monday, President Donald Trump said: "Every time Iran kills an American Soldier they will pay for that killing many times over!" He added that this directive had been passed on to every leader in the military. Saudi Arabia oil risk Jorge León, senior vice president and head of geopolitical analysis at Rystad Energy, said the Houthis' threat puts approximately 2.

5 million barrels per day of Saudi Arabian oil at risk at a time when traffic through the Strait of Hormuz is at a standstill. "With the Gulf's primary maritime outlet largely closed, the market is increasingly dependent on Saudi Arabia's East-West pipeline and Red Sea terminals to maintain export flows," León said Monday in a research note.

Saudi Arabia's East-West pipeline network, or Petroline, is a roughly 750-mile system that transports crude across Saudi Arabia, connecting Abqaiq on the oil-rich kingdom's eastern Gulf coast to the port of Yanbu on the Red Sea. "Any disruption at Bab el-Mandeb would therefore threaten not only Saudi shipments but one of the few remaining routes capable of compensating for the severe reduction in Hormuz traffic," León said.

"If a ceasefire does not materialize and Hormuz remains largely closed while the Houthi threat to Red Sea shipping intensifies, the risk of a significant rebound in oil prices would be substantial," he added. — CNBC's Chloe Taylor and Spencer Kimball both contributed to this report.

Yemen's Iran-aligned Houthis announced Monday they would impose a maritime blockade on Saudi Arabia, further throttling a global energy market already greatly restricted by Iran's closure of the Strait of Hormuz. This is why it matters and what it means for the Iran war and the global energy crisis.

It is not clear how the Houthis would carry out a maritime blockade of Saudi Arabia, its northern neighbor along the Red Sea coast, or whether it would include a return to attacks on shipping. 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 the Strait of 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 Feb. 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. The Houthis have been in a civil war against the Saudi-backed, internationally recognized government for more than a decade and have attacked Gulf neighbors with missiles and drones.

However, a 2022 truce between the country's warring sides largely held until last week, when Yemen's internationally recognized 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. 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. After Israel's genocidal 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.

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 campaign that shot down hundreds of drones and missiles. But some Houthi attacks continued until last summer, only ending completely with the Gaza cease-fire 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.

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 Saudi Arabia in retaliation for what they called the kingdom's siege of its ports and airports, including last week's strike.
