Iran begins de facto blockade of Strait of Hormuz

March 5, 2026 — Strait of Hormuz

Last updated: March 5, 2026

The Blockade

Iran moved to block commercial shipping through the Strait of Hormuz, a chokepoint between Iran and Oman:

  • ~500 oil tankers trapped in the Persian Gulf
  • Only five oil tankers left the area in a single day
  • The IEA declared this the largest supply disruption in the history of the global oil market
  • Shipping insurance costs for the region surged

Why It Matters

The Strait of Hormuz handles about 20% of the world’s oil and significant trade between Asia, Europe, and the Middle East. Its disruption affects every consumer on the planet through higher energy and goods prices.
