Strait of Hormuz: What Happens If Iran Shuts Global Oil Corridor?

Iran has declared it will block the Strait of Hormuz, threatening to disrupt one of the world's most vital energy transit chokepoints. The strait, measuring only 33 kilometers at its narrowest point, facilitates the passage of approximately 20 million barrels of oil daily—representing nearly $600 billion worth of annual energy trade.
The strategic waterway, bounded by Iran to the north and Oman and the UAE to the south, serves as the primary export route for major Gulf oil producers. Under international law, countries can exercise control over territorial seas extending 12 nautical miles from their coastline, and at its narrowest point, the strait's shipping lanes lie entirely within Iranian and Omani territorial waters.
The ramifications of a closure would be profound and far-reaching. While alternative infrastructure exists—including Saudi Arabia's 1,200-kilometer pipeline and the UAE's connection to Fujairah—these routes could only offset a fraction of the potential supply disruption, leaving an 8-10 million barrel per day deficit. Asian economies, which received 82% of crude oil leaving the strait in 2022, face particularly acute vulnerability. The escalating crisis has already caused shipping costs to soar, with supertanker rates from the Middle East to China nearly doubling to record highs exceeding $400,000.
