The Iranian Revolutionary Guard Corps (IRGC) confirmed on Thursday that its position regarding hostile vessels transiting the Strait of Hormuz has not changed, asserting that vessels it classifies as 'hostile' are unable to pass through the strategically vital strait. The statement signals continued Iranian leverage over one of the world's most critical maritime chokepoints. This declaration carries significant implications for global shipping, energy flows, and war risk insurance exposures in the Persian Gulf and Gulf of Oman.

Impact verdict
Medium impact. MEDIUM: Second-pass recalibration. An IRGC statement restricting hostile vessel passage creates a direct Marine Hull, Cargo and War Risk pathway for Persian Gulf traffic. Impact is not HIGH absent confirmed closure, vessel seizure, vessel damage, cargo loss, or a documented market-wide pricing/capacity response.

Iran has suspended indirect nuclear talks with the US in response to Israeli strikes in Lebanon and is threatening to close the Strait of Hormuz. The Strait of Hormuz is a critical chokepoint for global oil shipments, and any closure would have massive implications for marine, energy, war risk, and political risk insurance markets. This escalation raises the prospect of significant disruption to one of the world's most important shipping lanes.

US CENTCOM commander Admiral Cooper announced that 90% of Iran's military infrastructure has been destroyed through Operation 'Epic Fury', significantly degrading Tehran's ability to launch large-scale attacks or disrupt navigation in the Strait of Hormuz. The assessment marks a significant shift in the strategic balance in the Persian Gulf region. Iran's proxy networks in the broader Middle East have also reportedly been isolated as a result of the campaign.

US President Donald Trump and Chinese President Xi Jinping discussed the Strait of Hormuz during their Beijing summit, with both leaders agreeing it 'must remain open to support the free flow of energy'. This diplomatic development follows the IRGC's assertion that hostile vessels cannot transit the strait. Chinese vessels are actively transiting the waterway, underscoring Beijing's stake in keeping the route open. The discussions reflect broader international concern about the strategic chokepoint amid the ongoing Iran conflict.

UKMTO has issued a warning that a vessel was boarded by unauthorized personnel northeast of Fujairah, UAE, near the Strait of Hormuz, and is reportedly being taken toward Iran. The incident occurs in the context of ongoing IRGC assertions about denying passage to vessels it classifies as hostile. The seizure represents a significant escalation of maritime risk in one of the world's most critical shipping chokepoints, with direct implications for marine hull, war risk, and energy insurance lines.
