In February 2026, Iran’s Revolutionary Guards conducted live‑fire drills dubbed “Smart Control of the Strait of Hormuz,” a stark warning that President Trump largely ignored. Within days of the U.S. airstrikes, Iranian forces seized control of the waterway, menacing tankers with missiles and drones and halting commercial traffic.

The move forced global oil prices to spike and left energy traders scrambling. Analysts say Iran used shore‑based missiles and inexpensive drones instead of the expected minefield, exploiting U.S. naval assumptions and undermining a strategy built on “mining the strait.” The channel’s closure highlighted the U.S. reliance on a single chokepoint that can be commandeered within hours.

Trump’s administration had repeatedly warned that any interference would trigger a severe military response, yet it underestimated Iran’s willingness to use the strait as leverage. The incident exposed gaps in U.S. contingency planning, as allies failed to mount a swift naval counter‑offensive, leaving the United States in a strategic corner.

The episode underscores how a single geopolitical flashpoint can ripple through global markets, forcing investors to reassess risk in energy commodities and shipping. Firms with exposure to the Strait of Hormuz now face heightened scrutiny, and oil majors are revisiting supply‑chain resilience strategies.
