Click to expand

President Donald Trump urged China, Japan, the UK and other allies to send warships to the Strait of Hormuz on Saturday, escalating efforts to break Iran’s effective blockade of the world’s most important oil chokepoint.ft +1 The call came as US forces continued strikes on Iranian targets, including the Kharg Island oil export hub, and as attacks on commercial vessels mounted in and around the narrow waterway.bbc +1

The Strait of Hormuz normally carries around 20.3 million barrels of oil per day—roughly a quarter of global seaborne crude trade—leaving energy markets and shipping insurers on edge as traffic has largely stalled amid the US‑Israel–Iran war.eurasiareview +1 Iran’s Revolutionary Guard has said the strait is “under control” and closed to “tankers and ships of enemies,” while Washington insists it is acting to defend freedom of navigation.aa +1

In a Truth Social post and follow‑up comments, Trump said “many countries” affected by the closure “will be sending War Ships, in conjunction with the United States of America, to keep the Strait open and safe,” adding that US forces would meanwhile be “bombing the hell out of the shoreline” and targeting Iranian boats.reuters +1 France has indicated plans for a naval deployment, but key Asian partners and the UK stopped short of firm commitments.

Britain’s Ministry of Defence said it was “discussing a range of options” with partners to protect shipping, after a series of suspected missile, drone and mine attacks that UK maritime authorities say have hit at least 16 ships since late February.bbc +1 Japan’s government stressed it would make “its own decisions,” pointing to constitutional limits on Self‑Defense Forces operations as Prime Minister Sanae Takaichi prepares for talks with Trump in Washington.globalbankingandfinance +1 China has publicly urged de‑escalation and has not confirmed any participation, with ship‑tracking analysis showing Beijing’s tankers have largely abandoned the route rather than securing special passage.timesofisrael

International law experts noted that any multinational effort to “force open” the strait would sit in a legally fraught zone where rights of transit passage collide with the law of naval warfare. A detailed analysis on EJIL: Talk! argued that closing a strait to neutral shipping during armed conflict raises serious questions under the law of armed conflict at sea and states’ obligations to third‑party vessels.statista

Economic Shock Fears and Military Realities in a Blocked Chokepoint

The closure has already pushed oil prices higher and sent war‑risk insurance premiums soaring, with some underwriters suspending cover for transits near Hormuz.unctad +1 UN trade agency UNCTAD warned that a prolonged disruption could trigger “cascading effects” on energy, fertilizer and food markets, hitting import‑dependent developing countries hardest as cargoes are rerouted or cancelled.csis +1

Military planners and analysts cautioned that even a broad coalition would face a long, hazardous campaign to reopen safe passage. The US military says it has destroyed at least 16 Iranian mine‑laying vessels near the strait, but experts estimate that comprehensive mine‑clearing and restoring confidence among shippers could take weeks.itv +1 “Sending naval vessels without a diplomatic agreement … would only expose very, very expensive military vessels to very cheap but potentially very effective projectiles,” said Andreas Krieg, a Middle East security specialist at King’s College London.aa Iran, for its part, has framed the standoff as proof that the US “security umbrella” in the Gulf is “full of holes,” urging neighbours to expel “foreign aggressors.”aa

The Bigger Picture

The standoff over Hormuz has turned a long‑theorised worst‑case scenario—closure of the 22‑mile‑wide oil artery—into a live test of how far the US and its partners are willing, and able, to project naval power to protect global trade. Whether Asian importers and European allies join Trump’s proposed flotilla, or instead push for an emergency diplomatic arrangement involving Iran and Gulf states, will shape not only the trajectory of the war but also the future balance between gunboat protection and rules‑based management of the world’s sea lanes.unctad +1
