What is the Strait of Hormuz?

The Strait of Hormuz lies between Oman and Iran. It links the Gulf with the Gulf of Oman to the south, and the Arabian Sea beyond. It is 33km wide at its narrowest point, with the shipping lane just 3km wide in either direction. The United Arab Emirates (UAE) and Saudi Arabia have sought to find other routes to bypass the strait, including building more pipelines.

Why does it matter?

Almost a fifth of the world's oil passes through the strait - some 17.4 million barrels per day (bpd), out of a consumption of about 100 million bpd last year, data from analytics firm Vortexa showed. Opec members Saudi Arabia, Iran, the UAE, Kuwait and Iraq export most of their crude oil via the strait. Qatar, the world's biggest liquefied natural gas exporter, also sends almost all of its gas through the strait.

Any disruption to the oil supply will cause prices to rise and impact consumers.

Political tensions

The United States has imposed sanctions on Iran aimed at halting its oil exports.

 
 
 
 

Iran has threatened to disrupt oil shipments through the strait if the US tries to strangle its economy .

The US Fifth Fleet, based in Bahrain, is tasked with protecting commercial shipping in the area.
