The IMO Secretary-General has formally warned that safe passage cannot be assumed in the Strait of Hormuz, citing a volatile situation with no reliable security assurances. The Joint Maritime Information Centre maintains a CRITICAL maritime security classification for the Arabian Gulf, Gulf of Oman, and Strait of Hormuz, with vessel transits down 44.4% week-on-week. U.S. officials, including the Energy Secretary, characterise traffic and oil exports as recovering, citing nearly 1,000 commercial transits since the 8 April ceasefire and attributing tracking gaps to a rising share of dark transits.

Impact verdict
High impact. The IMO formal no-safe-passage declaration, the JMIC CRITICAL classification, and a 44.4% week-on-week decline in transits directly affect war risk, marine hull, and marine cargo underwriting for a chokepoint handling roughly 20% of global oil trade. The loss pathway runs through potential vessel strikes, seizures, and rerouting, with knock-on effects on energy supply chains. No specific vessel total loss or named commercial asset casualty is reported, so insured severity is bounded by the regulatory and security environment rather than by an explicit loss event. A diverging U.S. official narrative of recovering traffic adds uncertainty for underwriter response.

The International Maritime Organization (IMO) has issued a warning advising against transits through the Strait of Hormuz due to escalating security threats, including armed conflict, maritime incidents, and violence against seafarers. This represents a critical advisory affecting one of the world's most vital oil chokepoints, with immediate implications for marine war risk premiums, vessel routing, and energy supply disruption. The warning underscores severe threats to commercial shipping through Persian Gulf waters, a JWC listed war risk area.

Initial Detection
IMO Secretary-General Arsenio Dominguez warned that no safe passage exists in the Strait of Hormuz, stating there are no credible security guarantees for commercial shipping despite U.S. claims of recovering traffic. JMIC continues to classify the maritime security environment as 'CRITICAL,' with vessel transits down 44.4% week-on-week. This signals ongoing war risk exposure for marine hull, marine cargo, and energy underwriters operating in the Persian Gulf.
The current situation remains highly volatile, with no reliable security assurances in place. Under such circumstances, safe passage cannot be considered to exist.
