Türkiye raised its security level for Turkish-flagged vessels in the Strait of Hormuz to Level 3 on Sunday (2 March). The development follows Iranian restrictions on shipping after U.S. and Israeli strikes and confirmation of Supreme Leader Ali Khamenei’s death.

Warnings in the Strait of Hormuz began on 28 February, shortly after major U.S. and Israeli strikes on Iran, when radio broadcasts from Iran’s Islamic Revolutionary Guard Corps told vessels that “no ship is allowed to pass the Strait of Hormuz”, according to an official with the European Union’s naval mission Aspides.

The broadcasts were received over standard VHF maritime channels.

Though Tehran did not formally confirm a closure, Türkiye’s General Directorate of Maritime Affairs confirmed that Turkish ships were instructed to operate under the highest security level.

Mariners have been urged to follow navigational warnings closely and maintain contact with the main search and rescue coordination centre if needed.

The warnings triggered heightened caution among shipowners and national authorities, with some vessels anchoring outside the waterway and major carriers suspending transits amid the heightened risk to commercial shipping and regional military activity.

This reflects a broader maritime risk as oil and LNG shipments through this chokepoint, which handles about 20% of global crude flows, are significantly impacted.
