Analysts attributed growing US-Iran tensions to higher crude oil prices June 20. Light, sweet crude oil for July settled nearly $2.90/bbl higher on the New York market while Brent contract for August delivery also rose by more than $2/bbl in London.
An Iranian surface-to-air missile shot down a US military surveillance drone in what US officials called an “unprovoked attack.” But Iran says the drone was shot down over its territory.
The incident marked the latest in rising tensions between the US and Iran since President Donald Trump declared the nation’s exit from a 2015 international agreement about Iran’s nuclear program. Since then, US oil sanctions were imposed on Iran and encouraged other countries to refrain from buying Iranian oil.
Recently, US officials have accused Iran of attacks on oil tankers in the Persian Gulf region.
Trump tweeted on June 20 that Iran made a “very big mistake” by shooting a US drone.
