Why is the Strait of Hormuz so important to oil?

The U.S. has warned Tehran to stop killing protesters and not restart its nuclear program in the face of Iran's most violent unrest for years.

Analysts warn of a further escalation that could lead?Tehran, or any other country involved in oil exports, to try to close the Strait of Hormuz.

Here are some details on the?strait

What is the Strait of Hormuz?

The Strait is located between Oman, Iran and the Gulf of Oman. It connects the Gulf of Oman in the north with the Arabian Sea to the south.

The shipping lane is only 2 miles (3km) wide either way.

Why does it matter?

The Strait is responsible for about a fifth (or 5%) of all oil consumed in the world.

Data from analytics firm Vortexa revealed that on average more than 20 million barrels per day of crude oil, condensate, and fuels were transported through the Strait in 2017.

OPEC member Saudi Arabia,?Iran and the United Arab Emirates export the majority of their crude oil via the strait primarily to Asia.

Qatar, one of the world's largest LNG exporters, ships almost all its LNG through this strait.

The UAE and Saudi Arabia have been looking for other routes to bypass the Strait. The U.S. Energy Information Administration estimated in June of last year that existing UAE and Saudi pipelines have unused capacity of about 2.6 million barrels per daily (bpd).

Fifth Fleet of the United States, based out of Bahrain, has been tasked to protect commercial shipping in this area.

History of Tensions

In 1973, Arab producers led by Saudi Arabia imposed an "oil embargo" on Western supporters who supported Israel's war against Egypt.

While Western countries used to be the biggest buyers of Middle East crude oil, today Asia is the largest buyer, and the U.S. has become a major producer.

In the Tanker War, which lasted from 1980 to 1988, both sides tried to sabotage each other's trade.

In January 2012, Iran threatened a blockage of the Strait as a retaliation to U.S. sanctions and European ones. In May 2019, four vessels, including two Saudi oil tanks, were attacked near the UAE coast outside the Strait of Hormuz.

Iran seized three vessels in 2023, and another in 2024. Some of these seizures were made after U.S. tanker seizures related to Iran.

The U.S. attacked Iran's nuclear facilities last year. Iran was considering closing the strait. (Reporting and editing by Dmitry Zhdannikov, Ros Russell and Dmitry Zhdannikov.
