NATO 'considers deploying to Strait of Hormuz if it stays closed'

Summary

NATO 'considers deploying to Strait of Hormuz if waterway remains closed by July' NATO is considering deploying a mission to the Strait of Hormuz if the waterway remains closed by July. The Strait has been all but blocked since late February, after Iran deployed its navy there following the US and Israel's air war against the nation. Iran still has a chokehold on the Strait of Hormuz, the vital shipping lane for global oil supplies, even as the US military has enforced its own blockade on Iranian ports. The channel of water ordinarily sees a fifth of all oil pass through every day. Since its closure, oil prices have dramatically spiked. The result of the ongoing cessation of ships sailing through the waterway appears to have massively shifted NATO's strategy regarding the Middle East. Though Donald Trump has desperately tried to get the US' international partners to get involved with his war, the defence bloc has so far said it will only get involved once fighting has stopped and they can form a broad coalition that includes non-NATO members. But a diplomat told Bloomberg that the idea of sending a mission to Hormuz is gaining traction, though unanimous support has not yet been reached. A senior NATO official, meanwhile, said that while a few member nations still oppose authorising a mission, they will likely rally around the plan if the blockade carries on.

While some member states, like Spain, have outright refused to engage and have denied Trump the use of bases on their soil, others have quietly allowed the US to access their bases to provide logistical support. Trump has lashed out at his NATO allies for their refusal to engage in his war, recently announcing the US would pull 5,000 troops from its bases in Germany. Trump has considered himself an effective dealmaker above all else, but he appears to have hit a wall with Iran as his tough talk, threats and even military action haven't moved Tehran from its long-established positions. With shifting goals that make it difficult to judge the status of the US effort, Trump and his top aides have insisted the US has already won the war and that Iran is ready to reach an agreement in the wake of escalating US threats during a tenuous ceasefire. But Trump once again backed down, saying Monday that he'd put plans for an imminent resumption of attacks on hold at the request of Gulf Arab states because 'serious negotiations are now taking place, and that, in their opinion, as Great Leaders and Allies, a Deal will be made, which will be very acceptable to the United States of America, as well as all Countries in the Middle East, and beyond.' It comes as US Treasury Secretary Scott Bessent today called on allies to more forcefully disrupt Iran's financing networks and said the Treasury would scrub its sanctions list of outdated designations to make it easier for financial institutions to root out the most sophisticated terrorist financing schemes. In remarks prepared for delivery at an anti-terrorism financing conference after G7 finance leaders met in Paris, Bessent said that participants needed to 'stand with us in full measure' against Iran. Donald Trump speaks to the press aboard Air Force One enroute to the U.S. following his official visit with President Xi Jinping in China, May 15 AH-64 Apaches flying above the Strait of Hormuz during a patrol on April 17 'That will require, for example, our European partners to join the United States in taking action against Iran by designating its financiers, unmasking its shell and front companies, shuttering its bank branches, and dismantling its proxies,' Bessent said. 'It will require those of you in the Middle East and Asia to root out Iran's shadow banking networks.' As the Trump administration tries to pressure Tehran to reopen the Strait of Hormuz to unlock vital oil flows disrupted by the US-Israeli attacks on Iran, the US Treasury has stepped up its sanctions efforts through a program dubbed 'Economic Fury.' It aims to disrupt Iran's shadow banking networks, and has frozen nearly half a billion dollars worth of cryptocurrency linked to Iran's regime. To make this more effective, the Treasury will modernize its sanctions architecture because 'our adversaries adapt and innovate' by creating new shell companies. Most US Treasury sanctions are imposed on individuals, companies and other entities that are added to its Specially Designated Nationals List, which contains tens of thousands of designees that are cut off from the dollar-based financial system and see assets frozen. Anyone that transacts with designated entities risks being sanctioned themselves. 'To sharpen national security outcomes, Treasury is tailoring our sanctions program for the 21st century. We are reviewing outdated and obsolete designations to help financial institutions focus on the most sophisticated terrorist financing and sanctions evasion schemes,' Bessent said. An oil tanker burns after being hit by an Iranian strike in the ship-to-ship transfer zone at Khor al-Zubair port near Basra, Iraq, late Wednesday, March 11 He said the most effective sanctions are aggressive and targeted, and those left in place too long could create unintended consequences. 'Sanctions are meant to change behaviour, not to punish populations,' Bessent said. 'Sanctions left in place for years with no visible and tangible changes in behaviour can have generational impacts that are nearly impossible to predict.' He said the Treasury's approach would 'maintain agility to maximize effectiveness' and cited examples of easing sanctions on Syria and Venezuela after regime changes as examples of how the Trump administration intends to adjust sanctions.

Perspectives

Iranian Official

Iran has exercised its sovereign right to secure the Strait of Hormuz against US-Israeli aggression launched in late February, deploying naval forces to defend national waters and deter further attacks on its territory. This legitimate act of resistance has exposed NATO's willingness to escalate foreign intervention by considering a deployment mission if the closure persists, revealing the alliance's role in backing external threats to regional stability. Iran will continue to resist such hegemonic pressures while upholding its control over vital strategic routes.

Israeli

NATO's potential mission to the Strait of Hormuz exposes Iran's existential threat to Israel and global stability, as Tehran weaponizes its naval blockade—launched after US-Israeli strikes on its nuclear sites—to empower proxy networks and choke vital energy routes. This aggressive closure, holding a fifth of world oil supplies hostage, underscores the defensive necessity of preemptive action against Iran's expansionist regime. Growing alliance support signals recognition that unchecked Iranian aggression demands coordinated countermeasures to safeguard regional survival.

Neutral

Reports indicate that NATO is considering a naval mission to the Strait of Hormuz if the waterway remains closed after July. The strait has been largely blocked since late February following Iran's naval deployment after reported US and Israeli strikes on Iran. A diplomat cited by Bloomberg stated the proposal is gaining traction among members, though unanimous support has not been confirmed.

Western

NATO is evaluating a potential maritime deployment to the Strait of Hormuz to neutralize Iran's ongoing blockade and restore secure transit for global energy supplies. Iranian naval forces have effectively closed the critical chokepoint since late February, following US and Israeli operations targeting Iranian threats, driving sharp spikes in oil prices. Alliance officials indicate growing support for a mission to enforce freedom of navigation if the closure persists into July, prioritizing precision operations and a broad coalition to counter the strategic risk.

Pro-Peace

The US-Israeli air war on Iran has triggered a prolonged closure of the Strait of Hormuz, spiking global oil prices that inflict severe hardship on civilians through higher energy and food costs, especially in vulnerable regions. NATO's reported consideration of a military mission risks further escalation and civilian casualties, rather than addressing the root humanitarian crisis caused by blockades and conflict. Diplomatic efforts to negotiate safe passage and de-escalation with Iran and other stakeholders offer a far less destructive path than deploying additional forces.

Global South

NATO is weighing a naval deployment to the Strait of Hormuz to reopen the vital oil corridor, nearly five months after Iran asserted control in response to the US-Israeli air campaign. From a Global South vantage, the move exemplifies persistent Western efforts to police sovereign waterways and resource flows through military coalitions, disregarding regional states’ rights to secure their own maritime space. Internal NATO divisions over authorising the mission further expose the institutional fragility of such interventions when they clash with non-aligned resistance to external blockades.

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.
