BOISE – (December 29, 2025) – As Idahoans prepare to flood customer service counters with gift returns, there’s one thing they’ll treasure for as long as possible – cheaper gas prices.
Today, the average price for a gallon of regular in the Gem State is $2.84, which is five cents less than a week ago, 39 cents cheaper than a month ago, and 24 cents less than a year ago.
Today’s price is also just two cents higher than the national average, which currently sits at $2.82 per gallon – three cents lower than a week ago, 20 cents less than a month ago and 21 cents less than a year ago. Idaho has dropped to 18th in the country for the most expensive fuel, well below its usual position in the top ten.
“It’s difficult to predict future trends, but it’s a very positive sign that Utah, which supplies much of our finished gasoline, currently ranks 31st in the nation,” says AAA Idaho public affairs director Matthew Conde. “That gives us some optimism that we’ll kick off the new year on a positive note.”
The West Texas Intermediate benchmark for crude oil is currently trading near $58 per barrel, about $2 per barrel less than a month ago. But geopolitical tensions could destabilize crude prices at any time, with Iran recently declaring a “full-scale war” against the United States, Israel, and Europe and as negotiations continue between Ukraine and Russia.
“If the market predicts supply uncertainty, it could create upward pressure on the cost of crude and, in turn, pump prices,” Conde said. “But for now, with a lot of the gasoline and crude oil demand in hibernation mode, we may have enough of an offset to relieve supply chain pressure.”
