In the narrow waters of the Strait of Hormuz, where a fifth of the world's oil passes daily, the United States seized an Iranian cargo vessel over the weekend, unraveling in hours the fragile calm that Friday's diplomatic signals had briefly produced. Oil climbed 4% and equities retreated modestly — not in panic, but in the measured caution of markets that have learned to read geopolitical confrontation as a language of its own. The episode is a reminder that in contests over strategic chokepoints, relief is often borrowed, and the underlying struggle rarely pauses for long.

Similar to 2019 tanker seizures and 2020 Soleimani tensions; mirrors Cold War-era brinkmanship in contested waterways with asymmetric responses.
