On the morning of the 25th Beijing time, the US WTI crude oil futures rose 1.1% on Monday. There are signs that US gasoline demand is strengthening, and the outbreak of Middle East geopolitical tensions has supported crude oil prices.
New York Mercantile Exchange's August delivery of West Texas Intermediate (WTI) crude oil futures rose 90 cents, or more than 1.11%, to close at $81.63 a barrel.
Intercontinental Exchange's Brent crude oil futures for August delivery rose 77 cents, or 0.9%, to $86.01 a barrel.
As of the close of Monday this month, the monthly gains of WTI crude oil and Brent crude oil were 6% and 5.4%, respectively, according to the most active contract.
US crude oil had the worst monthly performance this year in May, but oil prices have rebounded as the market expects summer fuel demand to tighten.
