Hormuz Traffic Collapses to 10% as Multiple Vessels Attacked; Chevron CEO Warns of Ongoing Risk

Chevron CEO Mike Wirth disclosed on Bloomberg TV that multiple ships transiting the Strait of Hormuz suffered attacks this week, characterizing the incidents as previously unreported. Commercial shipping traffic through the chokepoint has fallen to roughly 10% of normal levels, down from the 20% of global petroleum that typically flows through the strait.

The 10% traffic figure is consistent with the broader Hormuz squeeze already underway since late May. If this persists past early June, LNG exporters (Qatar, Australia) face margin compression as spot LNG prices normalize from crisis levels — pushing some projects into negative cash flow.

Concurrently, the US munitions replenishment timeline (delayed to 2030-31 per May 27 signal) now overlaps with a potential extended Hormuz closure, which would degrade CENTCOM's ability to sustain a second simultaneous conflict. The constraint is not doctrine or intent — it's throughput.

WHY IT MATTERS

This is the second distinct Hormuz disruption signal in 72 hours — Treasury warned Oman on May 28 about sanctions over Iran-linked toll schemes, and now we have confirmation of active vessel attacks collapsing traffic to one-tenth normal flow.

The mechanism is supply-side: if sustained, a 90% traffic reduction forces European refineries dependent on Gulf crude into spot-market purchases at 20-40% premiums, bleeding $800M-$1.2B weekly from allied energy budgets.

Watch whether the Treasury's Oman threat escalates to actual designations by June 15 — that would signal the US is moving from deterrence to enforcement, which typically precedes either Iranian concessions or further Iranian escalation.

WHAT THIS DOESN’T TELL US

Did these attacks originate from Iranian state actors, Iranian proxies, or other hostile actors? The article attributes incidents to 'attacks' but does not identify the source. Attribution matters for the scale of retaliation risk.
