The Strait of Hormuz serves as a critical chokepoint through which nearly 20% of the world’s petroleum flows, linking the rich oil fields of the Persian Gulf with global markets. Its narrow passage, only about 21 miles wide at its tightest point, makes it especially susceptible to disruptions stemming from geopolitical tensions in the region. The ongoing friction between Israel and Iran adds a complex layer to these risks, as any escalation could threaten the already fragile security environment, prompting delays or blockades that send shockwaves through international energy prices.

Several vulnerabilities intensify the Strait’s strategic fragility:

  • Military presence: Multiple navies patrol the waters, raising the chances of miscalculation or confrontation.
  • Infrastructure target: Critical oil tankers and export terminals are prime targets for sabotage or missile strikes.
  • Environmental hazards: A strategic conflict could lead to oil spills, devastating marine ecosystems and complicating recovery efforts.
