The Strait of Hormuz crisis took its most dangerous turn yet in June 2026, as the United States and Iran traded direct military strikes over the world’s most important oil chokepoint. On June 8, an Iranian drone shot down a US Army Apache helicopter near the strait; within 48 hours the US had struck Iranian air-defense sites and Iran had retaliated against American bases across the Gulf — shattering a fragile ceasefire that had been on life support since April. The narrow waterway separating Iran from the Arabian Peninsula — through which roughly 20% of the world’s oil and about a third of its seaborne LNG normally flow — has been largely closed to commercial traffic since late February, with more than 600 vessels still stranded in the Gulf.
June 2026: US and Iran Trade Direct Strikes
After two months of an uneasy, repeatedly violated truce, the conflict reignited into open military exchange in the second week of June — the first direct US–Iran strikes centred squarely on the Strait of Hormuz itself.
Apache Helicopter Downed (June 8)
On Monday, June 8, a US Army AH-64 Apache helicopter went down in the sea near the Strait of Hormuz while patrolling the waterway. President Trump said the following day that the aircraft had been shot down by Iran; two US officials told CBS News that an armed Iranian Shahed drone struck the helicopter overnight. Both crew members were rescued within roughly two hours by an uncrewed US Navy drone boat — believed to be the first combat rescue of its kind — and were reported uninjured.
US Retaliatory Strikes (June 9)
Vowing to “respond to this attack,” Trump ordered strikes that hit Iran on Tuesday night. US Central Command said American forces struck Iranian air-defense systems, ground-control stations, and surveillance radar sites near the Strait of Hormuz — targeting the very assets Iran uses to monitor and threaten shipping through the chokepoint.
Iran Strikes Back at Gulf Bases (June 10)
Early Wednesday, Iran’s joint military command answered with attacks on US military bases in Bahrain, Kuwait, and Jordan, widening the confrontation beyond the strait and dealing a serious blow to the diplomatic track. The tit-for-tat strikes left the ceasefire — already extended indefinitely after April — closer to collapse than at any point since the war began.
Who Controls the Strait Now?
Despite a late-May framework under which Iran was meant to reopen the waterway, the strait remains effectively closed to most commercial traffic as of mid-June. Regional officials increasingly believe Iran has, in practice, taken control of Hormuz: passage is described as subject to permission, conditions, and political leverage rather than open transit. More than 600 vessels — including some 325 tankers — are still stranded in the Gulf, and the IRGC continues to police who moves through one of the planet’s busiest energy arteries.
The Crisis in Numbers
- Latest escalation: US Apache downed June 8 → US strikes on Iran June 9 → Iranian strikes on Gulf bases June 10
- Strait status: Largely closed to commercial shipping since late February 2026
- Vessels stranded: 600+ in the Gulf, including roughly 325 tankers
- Oil at risk: ~20 million barrels/day — about 20% of global seaborne oil trade
- LNG: ~One-third of seaborne LNG; Qatar’s Ras Laffan terminal effectively landlocked
- Brent crude oil: Around $95/bbl — elevated and volatile, spiking on each escalation
- Ceasefire: April 8 truce repeatedly violated and extended indefinitely; a 60-day extension deal awaits Trump’s approval
- IRGC toll: Reported ~$1 per barrel — roughly $2 million for a fully laden supertanker
- US bases hit (June 10): Bahrain, Kuwait, and Jordan targeted in Iran’s response
- Energy infrastructure: 40+ assets across 9 countries “severely damaged” (IEA)

US Navy Blockade (April 12–15)
Following the collapse of peace talks, President Trump ordered a full naval blockade of Iranian ports at the Strait of Hormuz. The blockade became operational within hours and is now in its third day. US Central Command reports the blockade is “fully implemented,” with no ships passing through the enforcement zone over a 24-hour period on April 14.
Six merchant vessels complied with orders to turn around during the first days of enforcement, though shipping data suggests at least four Iran-linked vessels may have crossed the waterway despite the blockade. Iran is estimated to be losing $435 million per day from the complete halt to economic trade. Hundreds of commercial vessels remain stuck in the region, caught between the threat of attack, sea mines, and the blockade itself.
Trump has indicated that direct peace talks could resume within 48 hours, describing the conflict as “very close to over” — though analysts remain skeptical given the scale of military deployments on both sides.
Peace Talks Collapse (April 12)
On April 12, high-stakes peace talks between the US and Iran collapsed in Islamabad, Pakistan, after 21 hours of marathon negotiations. US Vice President JD Vance, leading the American delegation, announced the failure, stating that no agreement could be reached on key issues including Iran’s 10-point plan for ending the conflict.
The talks, mediated by Pakistan, abruptly ended and left the existing two-week ceasefire in limbo. In response, President Donald Trump threatened to “blockade” the Strait of Hormuz and warned of further military action. Two empty supertankers attempting to transit the strait made U-turns immediately after the announcement. Iran’s Revolutionary Guard reiterated a “shoot at sight” policy for unauthorized vessels.
The April 8 Ceasefire
A two-week ceasefire between the US and Iran was brokered by Pakistan and officially announced on April 8 — the first pause in hostilities since airstrikes began on February 28. Key terms included:
- 14-day duration (set to expire around April 21)
- Safe passage for vessels coordinated with Iranian forces
- Framework for talks on Iran’s 10-point peace plan, which includes demands like US asset unfreezing and toll rights in the strait
However, compliance was limited from the start. In the first 24 hours after the ceasefire, only 10 vessels transited the strait — including just 4 tankers — while Israel continued bombing Lebanon on the same day the truce was announced.
Iran’s Toll Law and Safe Passage Deals
On April 4, Iran’s Parliament Security Committee formally approved a draft bill to impose transit tolls on commercial vessels. The “law of strategic action for peace and development of the Persian Gulf” would charge fees based on vessel type and cargo, with revenues distributed as “war reparations.” Legal experts note the law violates Article 26 of the UN Convention on the Law of the Sea, which prohibits charges solely for passage through international straits.
Iran has separately negotiated safe passage deals with five “friendly nations”: China, Russia, India, Iraq, and Pakistan. The Philippines became the latest addition on April 6, with assurances of “safe, unhindered, and expeditious passage.” Major shipping firms from other nations remain cautious — most Western-flagged vessels are avoiding the strait entirely.
Tanker Attacks in April
Aqua 1 — Cruise Missile Strike (April 1)
The QatarEnergy-owned fuel oil tanker Aqua 1 was struck by an Iranian cruise missile in northern Qatari territorial waters near Ras Laffan. Qatar reported that three missiles were launched from Iran; two were intercepted, but the third hit the vessel, causing a fire that was later extinguished. No casualties were reported. The attack came after a nine-day lull in Gulf shipping attacks.
MSC Ishyka — Drone Attack Claimed (April 4)
The IRGC claimed a drone strike on the MSC Ishyka, a container ship linked to Mediterranean Shipping Company, in the Strait of Hormuz. Iran cited alleged ties to Israel. However, no damage or injuries were confirmed, and maritime tracking showed the vessel was not actually hit. This brought the total to 21 confirmed IRGC attacks on merchant ships since the crisis began.
US Mine-Clearing Operations Begin
On April 11, the US military initiated mine-clearing operations in the Strait of Hormuz. Two Navy destroyers — the USS Frank E. Petersen (DDG 121) and USS Michael Murphy (DDG 112) — transited the strait to “set conditions” for de-mining, according to US Central Command. Operations continued into April 12, with three US officials verifying progress despite IRGC threats.
US officials said fewer than 10 mines had been laid by Iran, a lower number than the earlier estimate of “at least 12.” This is the first US mine-clearing effort since the war began.
New IRGC Naval Base on Qeshm Island
On April 9, the IRGC inaugurated a new naval base on Qeshm Island in Hormozgan Province, east of the Strait of Hormuz. The facility includes six buildings and is intended to consolidate IRGC control over the waterway. The move came just one day after the ceasefire was announced, signaling Iran’s intent to maintain its grip on the strait regardless of diplomatic outcomes.
UN Security Council — China and Russia Veto
On April 7, the UN Security Council voted on a Bahrain-led draft resolution to enhance maritime security and protect shipping in the Strait of Hormuz. The resolution was vetoed by China and Russia. The final tally: 11 in favor, 2 against (China, Russia), and 2 abstentions (Colombia, Pakistan). The UK expressed “deep regret” over the failure, while Iran’s allies framed the resolution as biased Western intervention.
Global Impact
The IEA’s Executive Director Fatih Birol described the disruption as “the largest supply disruption in the history of the global oil market.” It affects 11 million barrels of oil and 140 billion cubic meters of gas in daily global circulation. The impact extends well beyond energy:
- Fertilizers: About a third of global fertilizer trade passes through the strait. Nitrogen fertilizer prices have risen 30–40%, threatening food security.
- Helium: Qatar’s helium exports (critical for chip manufacturing) remain blocked, threatening semiconductor supply chains.
- LNG: Qatar’s Ras Laffan terminal — the world’s largest LNG export facility — effectively landlocked. Global LNG supply down ~20%.
- Methanol: One-third of global seaborne methanol trade passes through the strait, disrupting chemical manufacturing and plastics production.
- Aluminum, sulfur, graphite: Critical non-energy commodities also affected, with knock-on effects for the green energy transition.
What Comes Next
The June strikes have pushed the crisis to its most dangerous point yet. A late-May framework to extend the ceasefire by 60 days and open nuclear talks still sits unsigned on Trump’s desk, and the direct exchange of fire over the strait — a US helicopter downed, US strikes on Iranian air defenses, Iranian missiles on Gulf bases — has hardened positions on both sides. Whether the truce can be salvaged or tips back into full-scale war is now the central question.
Trump has signaled that peace talks could resume within 48 hours and described the conflict as “very close to over” — but his administration continues to tighten the economic vice on Iran with the blockade. Iran faces an estimated $435 million in daily losses, which could force a return to negotiations. Meanwhile, mine-clearing operations continue, and Iran’s safe passage deals with allied nations remain in effect.
The IEA’s Birol put it simply: the reopening of the Strait of Hormuz remains the “single most important” solution to the global energy crisis.
