Brent crude futures gained as much as 3.5% to $108.41 a barrel, while West Texas Intermediate crude futures rose 3.9% to $102.84 a barrel. The surge follows renewed Houthi attacks on Saudi Arabia and increased activity around the Bab el-Mandeb strait over the weekend. Additionally, Oman's foreign minister announced on Sunday that a regional meeting between Iran and Gulf states, originally scheduled for Monday to discuss the Strait of Hormuz, has been postponed, increasing concerns about Middle East supply disruptions.
