What is happening
The US military imposed a naval blockade on Iran in mid-April 2026, according to Al Jazeera 7, following what CNN reports was the downing of a US helicopter by an Iranian drone 6. US Central Command has since carried out precision strikes on at least seven vessels accused of breaching the blockade, Reuters and Al Jazeera report 37. The strikes have disabled ships accused of transporting Iranian oil or failing to comply with instructions.
On 8 June, the US Navy attacked the Palau-flagged MT Marivex in the Gulf of Oman, killing three Indian seafarers, TRT World reports 5. Days later, the MT Settebello was similarly struck, with three more Indian crew members confirmed dead 5. India summoned the US chargé d'affaires in protest 57. According to US Central Command, warnings were issued before strikes, which were aimed at disabling vessels that failed to follow instructions 5.
Iran's Revolutionary Guards have claimed retaliatory action, including closure of the Strait of Hormuz to all vessels and strikes on US airbases in Kuwait, Bahrain, and Jordan, CNN reports 6. State media claimed destruction of facilities at the Al-Azraq air base in Jordan 6. The US military has also launched strikes against Iranian surveillance, communications, and air defence sites 6. Explosions have been reported in multiple Iranian cities, including near Tehran and the Strait of Hormuz 6.
Reuters reports that two US military ships crossed through the strait on 11 June 2, and that the US is "setting conditions" to clear mines from the waterway 3. The UN Security Council held a vote on 11 June on a resolution regarding the crisis, with China opposing authorisation of force, Reuters reports 4.
Why it matters
The Strait of Hormuz is a critical chokepoint for global oil trade 14. The UN Food and Agriculture Organization predicts the crisis will disrupt global oil supplies and may lead to increased food prices worldwide 1. Business Insider Africa reports that 246 million barrels have been wiped from global oil inventories as a result of the crisis 14.
The blockade is believed to have significantly reduced Iran's oil exports, Al Jazeera reports 7. The New York Times notes that countries such as the United Arab Emirates and Qatar are seeing increased profits from the disruption, while others face economic losses 16. Reuters reports that Russia has increased its energy exports to cushion the economic blow 21.
The crisis has already caused tangible hardship. The BBC reports that high fuel prices linked to the conflict have paralysed public transport in Kenya 12, and Czech Radio notes shortages of food, fertiliser, and fuel in poor countries dependent on imports 13. The FAO warns the crisis could affect the stability of global agrifood markets and lead to higher energy costs worldwide 1.
The human toll has also been significant. At least six Indian seafarers are confirmed dead 5, with three more missing 7. India Today reports that an Indian cargo ship sank after a suspected drone strike near Oman 18. India has more than 18,000 seafarers deployed across the Gulf region, with 562 serving aboard Indian-flagged vessels in the affected waters and 13 Indian-flagged vessels currently stranded in the strait, TRT World reports 5.
Who is involved
US President Donald Trump ordered the blockade and has warned that strikes could resume if a deal with Iran is not reached, according to Fox News as cited by CNN 6. Politico reports Trump threatened to "blow up" Oman, a US ally, during an off-the-cuff cabinet meeting remark, urging the country to "get its act together" 1011.
Iran's Revolutionary Guards have been the primary Iranian actor, claiming retaliatory strikes and the closure of the strait 6. According to Iran International, an Iranian media outlet reported that Iran has begun receiving payment from ships passing through the strait 8.
India has emerged as a vocal critic of the blockade. The country summoned the US diplomat after strikes on vessels carrying Indian crew 7 and called the attacks "deplorable" 18. India also summoned the Iranian ambassador in April in response to earlier attacks, Al Jazeera reports 7. The Forward Seamen's Union of India has urged coordinated action to ensure crew safety 5.
China has opposed UN authorisation of force in the strait 4. According to Ynet and CNA, Trump stated that Chinese President Xi Jinping promised not to arm Iran 2024, though this claim has not been independently corroborated. South Korea has requested transparency from Iran regarding an attack on a Korean ship, Iran International reports 15.
Reuters reports that a vessel was seized off the UAE's Fujairah and was heading toward Iranian waters 19. Ynet reports that Iran seized what it described as a "floating armoury" near Hormuz 20.
What to watch next
The immediate focus is on whether diplomatic efforts can de-escalate the crisis. UN Secretary General António Guterres has urged all parties to work towards a diplomatic settlement, CNN reports 6. The outcome of the UN Security Council vote and any subsequent resolutions will shape the international response 4.
The safety of civilian shipping and seafarers remains precarious. The International Maritime Organization's secretary-general has raised concerns about the safety of international shipping, Al Jazeera reports 7. The US military's mine-clearing operations 3 and the question of whether the strait will remain navigable are critical for global trade.
The crisis's impact on US-India relations bears watching. Al Jazeera notes the incident could further damage ties, which are described as being at their lowest point in decades 7. How India responds to further casualties among its seafarers, and whether the US adjusts its blockade enforcement, will be significant.
Oil and commodity markets will remain volatile. The FAO warns of potential supply chain disruptions for oil-dependent countries and increased insurance costs for shipping in the region 1. Whether producer nations can compensate for lost Iranian supply, and how long inventories can sustain current consumption, will determine the breadth of economic fallout.
Finally, the risk of wider military escalation persists. Trump has vowed to attack Iran again if a deal is not reached 6, and Iranian forces have threatened continued closure of the strait 6. Whether the conflict expands beyond the waterway, and how regional powers such as Saudi Arabia and Israel position themselves, will shape the crisis's trajectory.
