Iran-US war latest: Strait of Hormuz closed indefinitely amid fresh strikes The Independent US strikes Iran, Tehran hits Gulf states, says Strait of Hormuz closed Reuters US, Iran Trade Wave of Attacks as Tehran Says Hormuz Closed Bloomberg.com Iran privately told Trump advisers "they made a mistake" in shooting at ships in Strait of Hormuz CBS News Iran war updates: IRGC navy declares Strait of Hormuz closed Al Jazeera
What it means
The IRGC's formal declaration of an indefinite Hormuz closure is a genuine escalation beyond prior tension signals — a chokepoint closure at this scale has historically been associated with a sharp crude spike and a defense sector bid. Airlines face a compounding jet-fuel cost shock. While Brent and Gold were already called in prior signals, the formal, indefinite closure announcement and active strike exchange represent new, incremental information that markets have not yet fully absorbed.
