Iran's IRGC navy says Strait of Hormuz closed until further notice, state media reports
Context
July 12 (Reuters) - Iran's Revolutionary Guards navy said early on Sunday it had closed the Strait of Hormuz until further notice after firing a warning shot at a vessel it said had attempted to transit along an unapproved route, state media reported.

What it means
A formal IRGC closure of the Strait of Hormuz is one of the most severe supply-shock scenarios for global oil markets — roughly a fifth of the world's seaborne petroleum transits this chokepoint with no quick alternative. Events of this type have historically been associated with large, immediate spikes in both Brent and WTI crude, a strong safe-haven bid in gold, and gains in defense names as military escalation expectations rise. This is a genuinely new, high-severity escalation step that has not been called in the prior signals on this situation. (Lower-conviction channels were filtered out by our selectivity bar.)
