Brent crude climbed past $70 a barrel on Thursday amid fears of a possible U.S. military attack on Iran — OPEC’s fourth-largest producer, which pumps about 3.2 million barrels per day.

Global benchmark Brent crude futures were trading at $69.34 a barrel at 12:15 p.m. ET on Thursday, after climbing to $70.44 at 9:30 a.m. — their highest level since Aug. 1, 2025.

US West Texas Intermediate crude futures were trading at around $65.29 a barrel at 12:15 p.m. ET on Thursday, up 3.29% from Wednesday’s close of $64.11.
