U.S. Strikes Hit Greater Tunb Island in Strait of Hormuz
Context
The U.S. military said on Wednesday it had attacked Iranian cruise missile storage and launch sites on Greater Tunb, one of several small islands in the Strait of Hormuz subject to a decades-old territorial dispute.
What it means
A U.S. strike on an Iranian-controlled island inside the Strait of Hormuz is a genuine escalation beyond prior signals in this conflict — targeting a chokepoint for roughly a fifth of global oil supplies. Events like this have historically been associated with sharp crude oil price spikes, a safe-haven bid in gold, and gains in defense stocks in the immediate aftermath.
