What it means
A direct US military strike on Iran combined with Iran declaring the Strait of Hormuz closed is one of the most severe geopolitical shocks in recent memory. Events of this type have historically been associated with sharp spikes in crude oil prices due to the chokepoint's role in global oil supply, strong safe-haven flows into gold, and gains in defense stocks. These are informational observations, not investment recommendations.
