U.S. drivers faced record-high gasoline prices over Labor Day weekend as global oil supply concerns and ongoing conflicts pushed fuel costs higher.
A late-summer increase in gasoline prices has made driving more expensive than ever during the Labor Day holiday period. Since the holiday weekend is traditionally one of the busiest travel periods of the year, higher fuel costs are adding pressure to road trip budgets across the country.
Gasoline Prices Reach Record Levels
The national average price for regular unleaded gasoline reached $4.15 per gallon on Monday, marking the highest Labor Day fuel price on record, according to AAA.
Gasoline prices had never exceeded $4 per gallon during Labor Day before. The previous record was set in 2012, when prices reached $3.82 per gallon.
Although prices have declined from the 2026 peak of $4.56 per gallon reached in May, drivers are still paying significantly more than last year. The current average is approximately 30% higher than the $3.20 per gallon consumers paid during the same period in 2025.
Diesel Prices Also Reach New Highs
Diesel prices have experienced an even sharper increase. Ahead of the holiday weekend, diesel reached a record $5.90 per gallon, compared with $3.71 per gallon one year earlier, according to AAA.
The increase in diesel costs is particularly concerning for freight companies, truck operators, farmers, and industries that depend heavily on transportation.
Global Oil Supply Pressures Fuel Price Increases
Oil supply disruptions remain the primary factor driving higher fuel prices. West Texas Intermediate crude futures were trading near $92 per barrel on Monday, compared with approximately $67 before the Iran War began on February 28.
Brent crude futures, the global benchmark, were trading around $97 per barrel, up from roughly $72 before the conflict.
Oil prices have remained volatile as disruptions in the Strait of Hormuz have limited global crude transportation. The strategic waterway has historically been one of the world’s most important routes for oil shipments.
According to the U.S. Energy Information Administration, approximately 4.9 million barrels of crude oil and petroleum liquids moved through the Strait of Hormuz daily during the second quarter of the year, significantly below the 21.6 million barrels per day recorded in late 2025 before the conflict began.
Refinery Disruptions Add More Pressure
Refinery shutdowns linked to both the Iran War and the Russia-Ukraine conflict have further reduced available fuel supplies.
Andy Lipow, president of Lipow Oil Associates, said that disruptions in the Middle East, combined with damage to refineries in conflict regions, have reduced the amount of fuel reaching global markets.
U.S. gasoline inventories were also below normal levels, with stocks 6% lower than average for the week ending August 28, according to the EIA.
Winter Gasoline Could Provide Relief
Consumers may receive some relief as the industry transitions from summer gasoline blends to cheaper winter-grade fuel.
Winter gasoline typically costs less to produce because it uses a different formulation. Summer gasoline blends, designed to reduce emissions during warmer months, are generally more expensive.
The Environmental Protection Agency announced that winter-blend gasoline could be sold beginning September 1 this year, ending summer fuel requirements earlier than usual in an effort to increase supply and reduce prices.
Oil Supply Remains the Key Factor
Despite the potential benefit from cheaper winter fuel, analysts say global oil supply conditions will continue to determine gasoline prices in the coming months.
Markets are closely watching whether the United States and Iran reach an agreement that would allow normal traffic through the Strait of Hormuz and ease pressure on global energy markets.
