The Iran war is producing the sharpest spike in US gas prices since Hurricane Katrina
The average US national gas price jumped a little more than $0.05 to $3.84 on Wednesday, per the American Automobile Association, its highest level since September 2023.
While front-month West Texas Intermediate futures have come off the boil, down roughly 20% from their March 8 peak, front-month gasoline futures are trading about 2% shy of their 2026 peak as of 8:20 a.m. ET.
Prediction markets currently imply that gas prices will end the month near (but below) $4.30 per gallon.

Prices are up nearly 29% over the past 20 days, per AAA, making this the sharpest such rise in fuel costs in more than two decades.
Hurricane Katrina, which made landfall in the US in late August 2005, was one of the deadliest and costliest natural disasters in American history. The damage wreaked havoc on energy infrastructure in the region, prompting gas prices to jump above $3 per gallon by early September from less than $2.30 in early August.
