Brent fell 1.3% to USD103.4 a barrel and WTI 1.5% to USD90 at the opening of 12 October trading, VnExpress reported via Reuters. Markets reacted to President Donald Trump's statement that Russia and Ukraine had agreed to stop attacking each other's energy infrastructure. The article says Ukraine was awaiting details and Russia had not commented on that statement. The prices are opening-session figures, and the announcement does not establish implementation of an agreement.
