U.S. equities finished the week higher, supported by resilient macro data and stable rate expectations, but gains came against a rapidly escalating geopolitical backdrop centered on the Strait of Hormuz—a critical artery for global energy supply. Iran reasserted control over the waterway, turning back or firing on multiple tankers and forcing others to reverse course, effectively disrupting transit flows. With roughly 20% of global oil supply moving through the strait, even partial disruptions introduced a meaningful risk premium into crude markets and capped broader equity upside.
