Why it matters

The rapid rise in gas prices in Montana is part of a broader national trend, with the national average price of gasoline climbing 97.9 cents per gallon over the past month. Experts attribute the price hikes to disruptions in global oil supply, which could push prices even higher and pose growing risks to the broader economy.

“The national average price of gasoline has risen 2.4 cents per gallon in the last week, averaging $3.95 per gallon today. The national average is up 97.9 cents per gallon from a month ago and stands 83.8 cents per gallon higher than a year ago. The national average price of diesel has increased 14.3 cents compared to a week ago and stands at $5.37 per gallon.”

“The situation remains highly volatile and unpredictable, but upward pressure on fuel prices is likely to persist as long as global oil supplies are constrained by the continued disruption in the Strait. We're likely to see the national average for gasoline push beyond the $4-per-gallon mark, while diesel could approach $6 per gallon and potentially set new records if conditions fail to improve. Americans have already spent nearly $8 billion more on gasoline over the past month, a trend that poses growing risks to the broader economy, while surging diesel prices may begin to reaccelerate inflation.”

Experts warn that if the situation does not improve, gas and diesel prices could reach new record highs, posing growing risks to the broader economy.
