CHEYENNE (WNE) — Average gasoline prices in Wyoming have risen 35.1 cents per gallon in the last week, averaging $3.04 per gallon Monday, according to GasBuddy.com’s survey of 494 stations in Wyoming.

Prices in Wyoming are 38.2 cents per gallon higher than a month ago, and stand 9 cents per gallon higher than a year ago.

The national average price of gasoline has risen 51.1 cents per gallon in the last week, averaging $3.45 per gallon Monday. The national average is up 54.1 cents per gallon from a month ago, and stands 41.6 cents per gallon higher than a year ago, according to GasBuddy data compiled from more than 11 million weekly price reports covering over 150,000 gas stations across the country.

“In just a week, consumers have seen gasoline prices surge at one of the fastest rates in years after oil prices spiked following U.S. strikes on Iran and the effective closure of the Strait of Hormuz,” said Patrick De Haan, head of petroleum analysis at GasBuddy, in a news release.

“With additional attacks across the Middle East over the weekend pushing oil above $100 per barrel for the first time in years, fuel markets are now rapidly recalibrating to the risk of prolonged disruption to global supply flows. As a result, gasoline prices in many states could climb another 20 to 50 cents per gallon this week.”
