Iran Declares Strait of Hormuz Closed Until Further Notice
Context
Iran said Saturday that it’s closing the Strait of Hormuz, saying no vessels will be allowed to pass through until foreign interference ends, according to state-run IRIB News.
What it means
A declared closure of the Strait of Hormuz — through which roughly one-fifth of the world's seaborne oil flows — is one of the most severe supply-shock scenarios in energy markets, historically associated with immediate and large spikes in both Brent and WTI crude prices. Safe-haven assets like gold have also historically surged in tandem with this type of extreme geopolitical shock, and defense stocks tend to benefit from escalating conflict expectations. This is an extremely high-severity event; market reactions will be sensitive to whether the closure is enforced in practice and how quickly major powers respond.
