The Strait of Hormuz is a narrow channel of water connecting the Persian Gulf to the Gulf of Oman. It is the world’s most critical energy chokepoint. Bordered by Iran and Oman, the passage is only 39 kilometers wide at its narrowest point. Before 2026, it was the primary maritime exit for the region's oil nations. While countries like Saudi Arabia and Iran have pipelines and terminals offering alternative routes, the vast majority of their exports still transited this passage. Every day, around 20 million barrels of oil, nearly a fifth of the world’s consumption, passed through. The massive tankers, some of the largest ships ever built, depended on this waterway to carry their cargo to global markets, making Hormuz’s stability vital to the world economy.

Frequently Asked Questions
Why is the Strait of Hormuz so important for the global economy?
It is the world's single most important oil chokepoint. Before the 2026 crisis, about one-fifth of global oil consumption, roughly 20 million barrels per day, passed through the strait, making it a critical artery for the world's energy supply.
Which European power first controlled the Strait of Hormuz?
Portugal was the first European power to control the strait. After a failed attempt in 1507, commander Afonso de Albuquerque successfully conquered Hormuz in 1515. Portugal held control for over a century until an Anglo-Persian force captured it in 1622.
What happened in the Strait of Hormuz in 2026?
A major crisis began on Feb. 28, 2026, after US and Israeli strikes on Iran prompted Iran to threaten the closure of the strait. Though not a formal blockade, attacks and mines halted nearly all shipping, causing oil prices to spike and creating an ongoing global economic disruption.
