STRAIT OF HORMUZ: CRITICAL MARITIME ALERT (Feb 28, 2026 22:30 UTC)
The world’s most vital energy chokepoint is currently at the center of a “De Facto” closure following the commencement of Operation Epic Fury—joint U.S.-Israeli strikes against Iranian targets.
Here is the situation for maritime operators and observers:
- The “Iranian Ban” vs. International Law
The Proclamation: The Islamic Revolutionary Guard Corps (IRGC) has declared the Strait of Hormuz “effectively closed” and “unsafe” for all transit.
VHF Warnings: Vessels in the region report receiving radio transmissions on Channel 16 (purportedly from the Iranian-flagged Bahram 1) stating: “From now on, the Strait of Hormuz is banned for all ships… No ship is allowed to pass.”.
The Legal Stance: UKMTO and Western authorities maintain that these broadcasts are not legally binding and do not constitute a lawful restriction under UNCLOS. They advise vessels to transit with “extreme caution”.
- Operational Reality: Diversions & Shutdowns
Carrier Suspensions: Industry giants like Hapag-Lloyd, Maersk, and CMA CGM have officially suspended all transits through the Strait until further notice to prioritize crew and cargo safety.
LNG Exodus: At least 9 LNG carriers were tracked changing course away from the Strait today.
Mixed Traffic: Despite the warnings, some vessels are still attempting to transit or are trapped within the Persian Gulf, facing a “maritime deadlock” at major hubs like Jebel Ali.
- Navigational Hazards: The “Electronic Fog”
GPS & AIS Spoofing: UKMTO warns of elevated electronic interference. Navigators are reporting massive spikes in GPS jamming and AIS spoofing, making positional data highly unreliable.
Standoff Requirement: MARAD (U.S.) has issued Alert 2026-001A, advising all commercial vessels to maintain a 30-nautical-mile standoff from U.S. military vessels to avoid misidentification during active combat operations.
- Immediate Impact
Oil Markets: Brent crude has surged to $78.50/bbl (+13%), with analysts predicting a jump past $100 if the blockade persists.
War Risk: Insurance premiums are expected to soar as Iran launches retaliatory strikes against regional infrastructure and U.S. bases in Bahrain and the UAE.
