Missoula, MT (KGVO-AM News) - Montana gas prices continue to rise. Patrick De Haan is the head of petroleum analysis at GasBuddy, and he provided the current numbers.    

“Average gasoline prices in Montana have risen 9.1 cents per gallon in the last week, averaging $4.55 per gallon today,” De Haan said. “Prices in Montana are 70.2 cents per gallon higher than a month ago and stand $1.38 per gallon higher than a year ago."

Montana is currently ranked 17th in the U.S. when it comes to the average price of gas, which is seven spots higher than last week.                  

"The national average price of gasoline has fallen 1 cent per gallon in the last week, averaging $4.47 per gallon today,” De Haan said. “The national average is up 45.2 cents per gallon from a month ago and stands $1.33 per gallon higher than a year ago. The national average price of diesel has decreased .5 cents compared to a week ago and stands at $5.62 per gallon.”

According to De Haan, the national average price of gasoline spent much of last week drifting lower after jumping early in the week as oil prices softened on hopes that diplomatic progress between the U.S. and Iran could help ease supply concerns. 

“However, that optimism faded after President Trump’s meeting with China’s Xi Jinping failed to produce a breakthrough on Iran, while renewed warnings toward Tehran have helped push oil prices higher again,” De Haan said. “With global oil inventories continuing to trend toward historically tight levels, markets remain extremely sensitive to geopolitical developments and potential supply disruptions. As a result, gasoline and diesel prices are likely to remain volatile, and with Memorial Day approaching, any sustained increase in oil prices could begin pushing retail fuel prices higher again in the weeks ahead.”
