Iran says Strait of Hormuz closed 'until further notice'
Context
The IRGC says it fired a warning shot at a vessel in the strait and is warning the US not to respond with "aggression".
What it means
Iran's announcement of a Strait of Hormuz closure — backed by an IRGC warning shot and direct threat to the US — is a significant escalation that has historically been associated with large, immediate spikes in crude oil prices, a safe-haven bid in gold, and gains in defense stocks. The 'until further notice' framing and active military posturing distinguish this from routine rhetoric, suggesting the risk premium is not fully priced in.
