What it means
Iran closing the Strait of Hormuz — through which roughly one-fifth of global oil flows — combined with active US strikes represents a genuine, extreme escalation rather than a continuation of prior tension. Historically, a credible Hormuz closure has been associated with very large spikes in crude oil prices, a strong safe-haven bid into gold, and gains in defense stocks. This is among the highest-severity supply-disruption and geopolitical-risk events possible.
