Iran-US war latest: Strait of Hormuz closed indefinitely after US and Iran trade fresh strikes
Context
Iran says it destroyed US aircraft carrier support and refuelling platforms in Oman after Centcom claims it struck 140 military targets
What it means
An indefinitely closed Strait of Hormuz combined with direct US-Iran strikes represents a genuinely new and severe escalation — not a continuation — historically associated with large, immediate spikes in crude oil prices, a strong safe-haven bid into gold, and gains in defense stocks. This is among the most extreme Hormuz scenarios historically, as prior episodes involved threats or brief disruptions rather than an indefinite closure backed by active strikes on US assets.
