On election day in the United States, gas prices reached historic highs. The average US gas price was $4.13 a gallon as of 10:00 a.m. New York time on Tuesday, according to GasBuddy. This is the highest price ever recorded on November 3 each year. It's also higher than any previous election day, including 2022, when US gas prices set an all-time high. The average price of diesel as of Monday was $6.29 a gallon, also the highest on record for Election Day, according to the American Automobile Association. And all this against the background of the lowest seasonal gasoline reserves. Diesel supply has also never been lower at this time of year, when the peak of the harvest season coincides with the start of the winter heating season.
