CASPER, Wyo. — Natrona County’s average gasoline price rose 8 cents in the past week to $2.65 on Monday. That’s more than three times the amount the national average rose, according to GasBuddy.
The national average rose 2.5 cents over the last week to stand at $3 per gallon, according to GasBuddy data compiled from more than 12 million individual price reports. That’s down 10.8 cents from a month ago and is 7.4 cents per gallon lower than a year ago.
The national average price of diesel increased 4.7 cents in the last week and stands at $3.638 per gallon.
AAA reports a national average price of $3.05, up 2 cents from last week. Wyoming’s state average remained flat at $2.93, AAA said.
“The national average saw a slight rise over the last week, as gas prices surged in parts of the Midwest after a refinery fire pushed wholesale gasoline prices sharply higher in the region,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “While the spike in prices in affected areas was significant, relief is likely in the weeks ahead as the situation stabilizes.
“For now, the possibility of a U.S.-China trade deal could lift oil prices on optimism that it would increase trade and reduce tariffs — potentially keeping the national average slightly above the $3-per-gallon mark for a couple more weeks before slipping back below $3 ahead of Thanksgiving.”
Natrona County’s average price of $2.65 is Wyoming’s lowest for the 10th consecutive week. The cheapest fuel in the county on Monday is $2.45 at Loaf ‘N Jug, 3830 E. 2nd St. and 285 Honeysuckle St., Sam’s Club, 4600 E. 2nd St., and Ridley’s Family Market, 300 SE Wyoming Blvd., according to GasBuddy’s report.

OIL MARKET DYNAMICS
With President Trump imposing new sanctions on Russia last week, oil prices jumped, with both China and India likely to decrease oil purchases from Russia, thereby reducing supply and causing oil prices to see solid weekly gains. In early Monday trade, WTI crude oil was up 3 cents to $61.53 per barrel, up from last week’s $57.03 per barrel start. Brent was also up in early trade, rising 2 cents to $65.96 per barrel, up from $60.72 in early trade last week. “Oil prices got a boost last week following the U.S. Treasury Department’s sanctioning of the two largest Russian oil companies. The impact on the oil market will depend on whether India and Turkey scale back their Russian oil purchases and if Russia finds alternative buyers for its oil,” said Giovanni Staunovo, UBS commodities analyst, in an e-mail.
