Oil prices rose on Monday after the United States and Iran exchanged attacks for the first time in a month, pushing the global benchmark for crude back above $90 a barrel after a sharp fall last week. The U.S. military said its forces attacked two Iranian rocket launchers attempting to disperse sea mines in the Strait of Hormuz. In response, Iran said it fired missiles at American air bases in Jordan, which the Jordanian military said it had intercepted.

Shipping in the Strait of Hormuz remains snarled, stocks are flat, and bond yields slip slightly. Refineries’ profit margins are expected to remain higher for longer. What they are saying: Gasoline prices are steady despite the volatility.
