Strait of Hormuz and Global Energy Security

The Strait of Hormuz is a narrow waterway between Iran and Oman-UAE, connecting the Persian Gulf to the Gulf of Oman and Arabian Sea. At its narrowest point, the shipping lanes are just 6 km wide (3 km in each direction), making it the world's most critical oil chokepoint. Approximately 30% of the world's seaborne crude oil, 20% of global LNG, and 16% of gasoline and naphtha pass through it daily. Iran's IRGC has periodically threatened closure, most recently in 2019 and now in 2026.

Key details
  • 20 million barrels of oil per day transited through the strait in 2024, worth ~$500 billion annually
  • Tanker traffic dropped approximately 70% following IRGC closure warnings in early March 2026
  • Brent crude rose 13% to $82/barrel within days of the conflict escalating
  • Alternative route: Oman's Madhab pipeline and Saudi Arabia's East-West pipeline have limited bypass capacity
