Despite the Brent benchmark staying below US$100 since Monday — its lowest since April 20 — oil prices rose on Thursday as US and Iran traded strikes
On Thursday morning, oil prices rose more than three per cent to US$97.80 after Iran's Revolutionary Guards said they targeted a US airbase in response to a US attack near Bandar Abbas airport.
Meanwhile, US President Donald Trump said at a Cabinet meeting on Wednesday that no single country would have control over the Strait of Hormuz and appeared to threaten Oman, a country with which the US has decades-long military and economic ties.
"Nobody's going to control (the strait)," Trump said. "It's international waters and Oman will behave just like everybody else or we'll have to blow them up. They understand that, they'll be fine."
Trump's comments and reports of new US military action showed that the two countries remain far apart, even after suggestions from the White House in recent days that an initial deal to end the war could be imminent.
At the time of this article's publication, Brent crude is hovering around US$96.
