FACTBOX: Strait of Hormuz: the world's most important oil artery
Reuters, , Friday 14 Jun 2019


Attacks on two tankers on Thursday forced the evacuation of more than 40 sailors south of the Strait of Hormuz, a vital gateway for the world's oil industry.

Below are details about the Strait:

What is the Strait of Hormuz?

* The strait lies between Oman and Iran

* It links the Gulf north of it with the Gulf of Oman to the south and the Arabian Sea beyond

* It is 21 miles (33 km) wide at its narrowest point, with the shipping lane just two miles (three km) wide in either direction

* The UAE and Saudi Arabia have sought to find other routes to bypass the Strait, including building more oil 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) versus consumption of about 100 million bpd in 2018, data from analytics firm Vortexa showed

* OPEC members Saudi Arabia, Iran, the UAE, Kuwait and Iraq export most of their crude via the Strait

* Qatar, the world's biggest liquefied natural gas (LNG) exporter, sends almost all of its LNG through the Strait

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 of Hormuz if the United States tries to strangle its economy

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

Major Past Incidents

* During the 1980-1988 Iran-Iraq war, the two sides sought to disrupt each other's oil exports in what was known as the Tanker War

* In July 1988, the US warship Vincennes shot down an Iranian airliner, killing all 290 aboard, in what Washington said was an accident and Tehran said was a deliberate attack

* In early 2008, the United States said Iranian vessels threatened three US Navy ships in the Strait

* In July 2010, Japanese oil tanker M Star was attacked in the Strait by a militant group called Abdullah Azzam Brigades linked to al Qaeda claiming responsibility

* In January 2012, Iran threatened to block the Strait in retaliation for US and European sanctions that targeted its oil revenue in an attempt to stop Tehran's nuclear programme

* In May 2015, Iranian ships seized a container ship in the Strait and fired shots at a Singapore-flagged tanker which it said damaged an Iranian oil platform

* In July 2018, President Hassan Rouhani hinted Iran could disrupt oil trade through the Strait in response to US calls to reduce Iran's oil exports to zero

* In May 2019, four vessels - including two Saudi oil tankers - were attacked off the UAE coast near Fujairah, one of the world's largest bunkering hubs, just outside the Strait of Hormuz
