Diesel prices have reached record levels, climbing to $6.50 per gallon due to ongoing supply constraints from the Iran conflict and other international pressures. This surge exposes a significant political weakness for the Republican Party just weeks before the midterms.
Data from AAA shows diesel has hit an all-time high of $6.53 as of Tuesday morning, compared to $3.69 a year ago. Some areas like California experience prices as high as $8.44. These increases have led to declining confidence in Donald Trump’s economic management. GOP lawmakers are urging immediate action to prevent further repercussions.
President Trump attributes rising diesel prices to the Russia-Ukraine war, viewing expensive fuel as a necessary cost to prevent a nuclear Iran. He promises quick price drops when the conflict ends and contrasts his fuel affordability record with that of his predecessor, Joe Biden. White House Spokeswoman Taylor Rogers reiterated Trump’s stance on American energy and economic policies in a recent statement to Newsweek.
States Facing High Diesel Prices
As of Tuesday morning, 16 states and the nation’s capital report diesel prices over $6.50 per gallon. Notable mentions include:
- California: $8.4387
- Washington: $7.4632
- Hawaii: $7.1360
- Indiana: $6.9138
- Michigan: $6.8813
Overall, diesel prices remain elevated across the country compared to a few months ago. Texas boasts the lowest per-gallon average at $5.97, yet this still exceeds pre-Iran-war costs by over $2.
Impact on Trump’s Approval
Using data from Civiqs, Newsweek analyzed Trump’s job approval in states with the highest diesel prices. Many states with $6.50 diesel have seen Trump’s approval drop below the negative 25 percent net rating from September 21.
Fuel price inflation affects voter preferences significantly. A Reuters/Ipsos poll in April found 77 percent of voters partly blame the president for the rising costs. Data for Progress revealed in September that 61 percent hold the Republican Party more accountable than Democrats for rising prices.
Economic Impact of High Diesel Prices
Besides political effects, record-high diesel prices are affecting the economy. Bank of America warns diesel is a crucial pressure point due to its importance in logistics, construction, and agriculture.
The agricultural sector faces challenges due to increased costs. John Boyd of the National Black Farmers Association highlighted that farmers are losing profit margins, pushing some out of business. The Department of Agriculture assured that the administration is actively addressing the issue.
Experts expect these pressures to persist until the Iran conflict is resolved. However, global supply issues and winter heating demands are additional concerns.
Bob Yawger from Mizuho Financial Group identified Middle East export issues and Ukrainian attacks on Russian facilities as contributing factors to high diesel prices. Tom Kloza from Gulf Oil added that disruptions in the Red Sea could sustain or raise current price levels.
