Gas prices "will likely start to rise across much of the country later this evening in response to Israel's attacks on Iran, which have caused oil prices to surge," Patrick de Haan, the head of petroleum analysis at GasBuddy, said on Friday in a post on X.

Oil prices surged, stocks dropped and investors flocked to safe havens like gold on Friday after tensions between Israel and Iran escalated, stoking concerns of a broader conflict in the region.

Ukrainian President Volodymyr Zelenskyy says rising global oil prices following Israeli strikes on Iran will strengthen Russia by increasing its oil revenues, aiding its war effort in Ukraine.

That scenario now appears alarmingly close. On the evening of June 12th, Israel launched dozens of air strikes on Iranian military and nuclear sites. The attack threatens to inflame the Gulf, which pumps a third of the world’s oil. Brent crude, the global benchmark, rose by 8% on June 13th, to $74 a barrel (see chart). How high might it now go?
