The question
Why is the Strait of Hormuz important?
It is the only sea route out of the Persian Gulf, and about a fifth of the world’s oil and a quarter of its LNG pass through a channel 21 nautical miles wide. There is no full alternative.
One channel, no detour.
The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and the Indian Ocean beyond. It is the only maritime exit for the crude and gas produced by Saudi Arabia, Iraq, the United Arab Emirates, Kuwait, Qatar, Iran, and Bahrain. Roughly 20 million barrels of oil move through it every day in normal conditions, close to a fifth of what the world consumes and about a quarter of all oil carried by sea.
Qatar ships almost all of its liquefied natural gas through the strait, which is why it also accounts for about a quarter of global LNG trade. For many of these exporters there is no other way to reach the open ocean.
Bypass pipelines exist, the Petroline, ADCOP, and Goreh-Jask lines, but together they can carry only about 40% of normal Hormuz throughput. The remaining 60% of Gulf crude has nowhere to go that does not cross the chokepoint. That is why a single 21-mile channel can set the price of oil for the entire world, and why a disruption there is felt at fuel pumps thousands of miles away within hours.

Frequently asked.
FAQWhy is the Strait of Hormuz so important?
The Strait of Hormuz is the only sea route between the oil-rich Persian Gulf and the open ocean. About a fifth of the world's oil supply and roughly a quarter of its liquefied natural gas pass through a channel just 21 nautical miles wide at its narrowest. No combination of pipelines can carry more than about 40% of that volume, so most Gulf crude has no alternative path. A disruption there raises energy prices worldwide within hours.
How much oil passes through the Strait of Hormuz?
Roughly 20 million barrels of oil per day in normal conditions, close to a fifth of global consumption and about a quarter of all seaborne oil trade, carried by 90 to 100 commercial vessels a day. It is the single busiest oil chokepoint in the world. The live daily transit count, against a ~94/day pre-crisis baseline from IMF PortWatch, is tracked on the homepage.
What happens if the Strait of Hormuz is closed?
A closure strands Gulf crude and LNG behind the chokepoint, forces tankers onto far longer routes or pipelines that cannot absorb the volume, and pushes oil prices sharply higher. The 2026 closure that began on 28 February did exactly this: war-risk insurance jumped to multiples of normal, major carriers rerouted around the Cape of Good Hope, and hundreds of ships were left stranded on either side.
