Ships sail silent as U.S.-Iran tensions tighten the Strait of Hormuz

U.S. strikes on Iran have prompted Iranian retaliation across the Gulf, leaving only a handful of vessels to cross the Strait of Hormuz with their transponders turned off.

Over the weekend, U.S. forces launched roughly 140 attacks on Iranian positions, triggering Iranian strikes on locations in Jordan, Bahrain, Kuwait and Oman. The Joint Maritime Information Center confirmed that the southern lane of the Strait of Hormuz near Oman remains navigable, yet classified the threat as severe. Shipping activity has plummeted, with Shipfinder reporting only 23 vessel passages in the last 24 hours, many of which are disabling their transponders to avoid detection.

Brent crude oil prices climbed to $77 per barrel, reflecting investor concern over supply disruptions. Analysts warn the undeclared naval conflict could persist for months, keeping oil flows below normal levels and pressuring prices toward $90 a barrel. The tension is also rippling through global markets, with mixed reactions across regions and a modest dip in U.S. futures.
