Strait of Hormuz: Most important oil artery of the world

Three weeks ago I wrote an article ‘Brewing turmoil in Pakistan’s backyard’ and the concluding remarks were, “The fact remains that none of the country (United States or Iran) wants to get the blame for initiating a conflict, but it doesn’t mean that the threat of eminent war is not there. There is a fear that miscalculation or misunderstanding can trigger confrontation and an outbreak of war. As the US expands its military presence in the region, the risk of beginning an accidental war rises further.”

The apprehension came true last Thursday when two oil tankers were attacked and left adrift in the Gulf of Oman. Washington was prompt in accusing Tehran of being behind a similar incident on 12^th May when four tankers were attacked in the same area, a vital oil shipping route. Russia was quick to urge caution, saying no one should rush to conclusions about Thursday’s incident or use it to put pressure on Tehran, which has denied the US accusations. There were no immediate statements apportioning blame after Thursday’s incidents, nor any claims of responsibility.

WHERE IS STRAIT OF HORMUZ LOCATED?

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. 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.

CURRENT POLITICAL TENSION

The US 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 US 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 US said Iranian vessels threatened three of its 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 program.

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.
