US and Iran trade strikes as Tehran closes Strait of Hormuz until further notice
What it means
A direct US-Iran military exchange combined with a formal Strait of Hormuz closure is one of the most severe geopolitical shocks in modern history — roughly 20% of global seaborne oil is at risk of disruption. Events of this magnitude have historically been associated with immediate, large spikes in crude oil prices, a strong safe-haven bid for gold, and sharp gains in defense stocks. While the continuation context notes 12 prior signals on Iran-US tensions, a formal Hormuz closure with actual strikes between the two parties is a genuine, qualitative escalation beyond what was previously called.
