U.S. benchmark oil prices settled Tuesday at their highest in three weeks, as trade-war optimism helped “alleviate consumer-demand concerns and recession worries,” said Tyler Richey, co-editor at Sevens Report Research.

Oil futures added to last week’s gains as the U.S. and China agreed to slash tariffs for 90 days, but settle off the day’s highs as talks on Iran’s nuclear program and the Russia-Ukraine war keep open the possibility of sanctions eventually being lifted.
