What it means
A direct US military strike on Iran combined with IRGC attacks on oil tankers near the Strait of Hormuz represents a genuine, major escalation — not a continuation of prior tensions. Events of this severity have historically been associated with sharp spikes in crude oil prices due to Hormuz supply risk, a strong safe-haven bid into gold, and significant gains in defense stocks. Broad equities and airlines face meaningful short-term pressure, though this chain focuses on the four highest-conviction, most direct relationships.
