US restores blockade in response to Iran attacks on ships in Strait of Hormuz
What it means
A US blockade of the Strait of Hormuz in response to Iranian attacks represents a genuine, severe escalation — not a continuation — and has historically been associated with immediate large spikes in crude oil prices given the chokepoint's role in global supply. Safe-haven assets like gold and defense stocks have also historically risen during direct US-Iran confrontations. This is a high-severity, novel escalation that distinguishes it from the prior ongoing situation context. (Lower-conviction channels were filtered out by our selectivity bar.)
