IRGC designates specific routes through the Strait

What Happened

On Thursday, the Singapore-flagged container ship Ever Lovely was struck by a projectile on its starboard side 7.5 nautical miles southeast of Oman’s Dahit port, causing damage to the bridge but no casualties, according to UKMTO. British maritime security firm Ambrey assessed the incident as an attack. U.S. officials told The Wall Street Journal that the attack was conducted by Iran’s Islamic Revolutionary Guard Corps (IRGC). The same day, the IRGC declared that safe passage through the Strait of Hormuz would only be possible via routes designated by Iran, threatening action against non-compliant vessels. Following the attack, the International Maritime Organization paused its plan to evacuate the strait, where hundreds of ships have been stranded since the Iran war began at the end of February. Oil prices edged up about 1% amid renewed concerns over Gulf oil flow disruptions.

Key Actors

Why It Matters

The Strait of Hormuz is a critical chokepoint for global oil transport. Iran’s imposition of designated routes and an attack attributed to the IRGC escalate tensions in the Gulf, directly threaten freedom of navigation, and risk wider disruption to energy markets, as reflected by the immediate oil price increase. This development signals a potential shift to an active blockade-like posture by Iran, leveraging its geographic position in a broader conflict that began in late February.

Watch For

Monitor whether Iran or its proxies conduct further attacks on vessels not using the designated routes; observe U.S. and allied naval responses to safeguard commercial shipping; track IMO evacuation resumption decisions and new guidance; watch for revisions to war risk insurance and shipping rerouting; and follow oil price volatility and any emergency diplomatic meetings, including potential UN Security Council sessions.
