Key takeaway

The US naval blockade widened to 121 redirected ships even as the negotiating channel froze.

CENTCOM (US Central Command) confirmed on Monday 1 June that it had redirected 121 commercial vessels and disabled five ships to enforce the US blockade, up from the 116 redirections it logged on 30 May 1. CENTCOM is the US military command running operations across The Gulf. It redirected 121 vessels yet disabled only five, a roughly 4% kinetic share of the ships it stopped, which means most traffic is turned by warning rather than by fire.

The container ship MSC Sariska V was holed by an unidentified projectile in the Persian Gulf on 1 June, a large breach above the waterline, with no claim of responsibility 2. It is the third named commercial vessel struck after the Olympic Life and the Lian Star. No party has claimed the strike, so whether it was the IRGC, a proxy, or stray ordnance stays unconfirmed.

A blockade this wide raises war-risk premiums and, for European and Asian consumers, means dearer goods and slower deliveries. It widened on the precise day diplomacy briefly opened and slammed shut, with Iran's 09:56 talk suspension running in parallel above it. The militaries kept doing what they do regardless of the diplomatic whiplash overhead.

Deep Analysis

In plain English

CENTCOM (US Central Command) is the US military's regional command for the Middle East. It has been stopping commercial ships from entering Iranian ports since mid-April 2026, turning them away and in some cases disabling them. By 1 June it had redirected 121 ships and disabled five. A 'disabled' ship means it cannot move under its own power and must be towed, leaving crew stranded on board. Separately, the container ship MSC Sariska V was hit by an unknown projectile while sailing through the Persian Gulf. No country or group has said they did it. This is the third named civilian cargo ship to be hit in the conflict. When no one claims an attack on a merchant vessel, it complicates insurance claims and leaves the ship's operators, crew and cargo owners in legal limbo.

Kananaskis ended without a joint communique for the first time in the body's history; Macron credited G7 pressure with speeding the ceasefire while Trump publicly denied the summit played any role. The split between US and European G7 partners over what the memorandum means for sanctions relief was the direct cause of the text failure.

London-based P&I mutual clubs declined to underwrite Hormuz crossings while the IRGC Strait Authority remained operational, making the passage commercially impassable regardless of the memorandum's terms. Shipping operators said they would wait weeks for on-water conditions to change before routing tankers through.

P&I mutual insurers declined to underwrite Hormuz crossings on 15-16 June while the IRGC's Strait Authority remained in operation, reducing actual transits to two vessels against a pre-war daily rate of 94. The corps' revenue-generating toll mechanism, created 5 May and collecting $1.5-2 million per VLCC in crypto, has not been stood down and cannot be dissolved by Ghalibaf's signature.

Netanyahu admitted he had not seen the memorandum's text but confirmed IDF forces would stay in southern Lebanon; Finance Minister Smotrich called for ten Beirut buildings destroyed per Hezbollah drone and National Security Minister Ben-Gvir said the agreement 'does not bind us in any way'. Israel signed nothing in Islamabad and is the central unresolved variable in the Lebanon clause.

Around 60 MPs signed a letter demanding Ghalibaf explain the memorandum; Paydari faction MP Sabeti said the deal violates the Supreme Leader's red lines, and MP Aboutorabi argued the document carries binding obligations 'that cannot be resolved by simply changing the name'. President Pezeshkian defended the negotiators against accusations of betrayal, confirming the fracture inside Iran's political class.

Vance signed on 15 June and said the memorandum was 'not conditioned on Israel withdrawing from Lebanon' while also saying it 'envisioned a ceasefire that covers both Iran and Lebanon'. The two formulations are incompatible and hand Iran's foreign minister a ready-made violation claim before Geneva.
