U.S. motorists are poised to pay the lowest Labor Day gasoline prices in five years, with fuel-price tracker GasBuddy projecting a national average of $3.15 a gallon for the Sept. 1 holiday. The level is 14 cents below last year’s mark and sits well under the pandemic-hit 2020 average of $2.22, capping what GasBuddy calls the most affordable summer for drivers since COVID-19 struck. The U.S. Energy Information Administration put the average retail price of regular gasoline at $3.15 a gallon on Aug. 25, about 5% cheaper than a year earlier. The agency attributes the drop to a 15% slide in Brent crude to roughly $67 a barrel, growing global oil supply and the seasonal switch to less-costly winter-grade fuel. While nationwide prices are falling, the EIA notes that refinery outages have triggered localized increases and that the West Coast remains the priciest region. Lower pump costs arrive as holiday travel accelerates. The Transportation Security Administration expects 17.4 million passengers between Thursday and Wednesday, a record for the Labor Day period. The White House has seized on the figures, saying President Donald Trump’s efforts to expand domestic energy production are easing household budgets, while analysts caution that hurricanes or geopolitical shocks could still reverse the trend later in the year.
