Prices of crude oil fell yesterday after the United States President, Donald Trump, said that he was meeting in the White House Situation Room to make a final determination about an agreement with Iran.

According to Reuters, Brent crude futures for July, which expire later on Friday, were down $1.89, or 2%, at $91.82 a barrel. The more active August contract was down $1.89, or 2%, at $90.81.

WTI U.S. oil futures were down $1.70, or 1.9%, at $87.20. Recall that oil prices were on track for their steepest weekly decline since early April after reports that the U.S. and Iran had reached agreement on a potential ceasefire extension.

Reuters noted that the price drop could be forcing some market players to close their long positions.”
