MAPPED: Where gas prices are rising the fastest from the Iran conflict

Gas prices are surging as the ongoing conflict with Iran drives up crude oil costs, fueling higher prices at the pump nationwide.

The national average now stands at $3.98 per gallon, up $1 from a month ago, according to AAA.

Prices are climbing across nearly every region, with some states already well above the national average.

THE UNLIKELY TOOL TRUMP IS EYEING TO TACKLE RISING OIL PRICES AMID THE IRAN CONFLICT

Diesel prices are climbing faster than gasoline, reflecting their close ties to freight and industry—meaning increases can ripple through supply chains and raise costs across the economy. 

Diesel averaged $5.41 a gallon, up $1.65 over the same period, according to AAA, surpassing $5 for the first time since December 2022 as the war in Iran continues to disrupt global energy supplies.
