US Launches Fresh Strikes as Iran Closes Strait of Hormuz – 12 July 2026
What it means
An actual Iranian closure of the Strait of Hormuz — as opposed to prior threats — is a qualitatively new escalation that has historically been associated with immediate, large crude-price spikes, a sharp safe-haven rush into gold, strong gains in defense names, and severe pressure on airline stocks via fuel costs. While prior signals already captured directional moves in crude and gold, a physical chokepoint closure of this magnitude represents a genuine step-change that markets would need to reprice significantly beyond those earlier calls.
