(The Center Square) – Wisconsin saw a 44.8-cent increase in the average price per gallon over the past week and diesel prices hit a record high Monday with an average price of $5.62 per gallon, topping the previous record set in 2022.
Wisconsin’s price increase to $4.37 per gallon of unleaded gas ranked below Indiana, Ohio, Michigan and Illinois as the Midwest states felt the impact of both the conflict in the Middle East and issues at a BP refinery in Whiting, Indiana.
“Gasoline prices rose in every state over the last week, with some of the most significant and fastest increases concentrated in the Great Lakes, where states like Michigan, Indiana, Ohio, and Illinois saw sharp spikes, while Wisconsin experienced more modest gains,” Patrick De Haan, head of petroleum analysis at GasBuddy, wrote. “At the same time, diesel prices surged to new records in parts of the region, with some areas touching the $6-per-gallon mark.
“While refinery outages were a key driver behind those outsized increases, early signs of improvement could help ease some of the most extreme price pressures in the Great Lakes in the days ahead. Beyond the region, markets are also digesting a wave of new developments – including OPEC+ raising production for June and President Trump outlining a plan to free stranded ships—which could help restore some supply. However, with so many moving pieces, the outlook remains highly fluid, and while some localized relief may emerge, broader price volatility is likely to persist in the near term.”
Despite the increases, Wisconsin remained below the national average of $4.42 per gallon as of noon Monday.
Indiana rose 83.3 cents, Ohio went up 78.1 cents, Michigan went up 68 cents and Illinois rose 49.3 cents over the week.
Wisconsin diesel prices rose 73.2 cents over the week, behind only Michigan and Indiana and ahead of Illinois and Ohio. The median national price is $5.49 across the U.S.
