Gas Prices In Illinois, Iowa Going Up Amidst U.S.-Iran Attacks

It may be time to get your bicycle out.

Over the weekend, the U.S. and Israel attacked Iran, which resulted in a huge jump in oil prices. It pretty much sets the stage for an immediate jump in gas prices for us here, according to CNBC.

It's already not looking good. Stats from a survey of 2,036 stations in Iowa by GasBuddy show that as of today (3/2/26), the average price of gas in the state is $2.63.

Iowa's gas price average is 12.5 cents higher than a month ago. Don't love that.

The numbers show the cheapest gas in Iowa was $2.14 while the most expensive was $4.11, almost double.

As for Illinois at the moment, where gas is already pricey, the average price for gas today (again, 3/2/26) is $3.06, which is 11 cents higher than last week.

So basically, part of the reason that the Iran Conflict could up gas prices here is because Iran closed the Strait of Hormuz, which impacts tanker traffic. About 20% of the world's oil goes through the strait every day.

Patrick De Haan, Head of Petroleum Analysis at GasBuddy, said:

The national average price of gasoline has climbed for a fourth straight week, driven primarily by seasonal tightening and broader market dynamics. Looking ahead, markets will now begin reacting to this weekend’s U.S.–Iran attacks, which have elevated geopolitical risk premiums even in the absence of immediate supply disruption. Oil prices have firmed as traders assess the potential for further escalation, and while fundamentals such as inventories and refinery activity remain important anchors, the risk of broader instability— particularly involving key transit routes— has injected fresh uncertainty into energy markets. In the week ahead, gasoline prices are likely to face heightened upward pressure as seasonal trends continue and markets navigate this evolving geopolitical landscape, with the national average poised to reach the $3-per-gallon mark for the first time this year.

If the price of oil goes up $10, that's going to mean a 25 cent increase for you at the pump.
