In the 1950s the United Arab Emirates and Iran opened their coasts to commercial tanker traffic, turning a regional waterway into a vital conduit for Middle‑East crude. Early pipelines and port upgrades accelerated export volumes, and the global oil boom cemented the Strait as a chokepoint whose smooth operation became a silent assumption for world trade.
Decades of growth gave way to conflict in the 1980s, followed by a period of uneasy stability. The 1990s saw multinational naval patrols and diplomatic accords, yet occasional skirmishes kept the route on alert. By the 2010s, missile drills, cyber threats, and heightened U.S.–Iran tensions revived worries that a sudden shutdown could shock the global energy system.
