In the early morning of September 14, Saudi Aramco's "world's largest oil processing facility" and an oil field were attacked by unmanned aerial vehicles, resulting in a fire at a "processing facility critical to global energy supply". Saudi officials said at the time that the attack reduced Saudi crude oil supply by 5.7 million barrels per day, accounting for about 50% of Saudi oil production.
On October 11, an oil tanker of the Iranian National Oil Company exploded and caught fire near the Saudi port city of Jeddah, causing serious damage to the ship. After the explosion, the oil leaked into the Red Sea. Technical experts believed that this was a terrorist attack. The official website of Iran's Ministry of Oil reported that the explosion of the oil tanker may be caused by missiles.
With the successive attacks by Saudi Arabia and Iran, the tension in the Middle East continues to rise, especially the relationship between Iran and Saudi Arabia. This undoubtedly has a huge impact on the international oil market, not only endangering the global oil supply, but also triggering the rise of the international crude oil price.
At 13:30 Beijing time on October 11, US WTI crude oil and Brent crude oil rose by more than 1%. WTI crude oil stood at $54/barrel, and Brent hit the $60/barrel mark, breaking the new high since October 1.
As a downstream industry of oil, the price of some chemical raw materials has also been greatly affected. After the Iranian oil tanker accident, the price of some products began to rise.
