U.S. gas prices are expected to hit a new September record, according to an analysis by the motor club AAA. As of Thursday, the average price for a gallon of gasoline was $4.48, with the average for the month of September sitting at $4.30. If current trends continue, prices could rise by nearly 50 cents, surpassing the previous September record set in 2023. Normally, the beginning of autumn brings a decline in gas prices, but this year, factors like geopolitical tensions and high oil prices are keeping them elevated. AAA noted that "lingering volatility in the Strait of Hormuz and the high cost of crude oil are driving up pump prices," and added that "This month is on track to set a new September record." If September breaks the record, it will be the second consecutive month that gas prices have set a new benchmark. August was the first time in history that gas prices remained above $4 for the entire month. California currently has the highest gas prices in the country, with an average of $6.23 per gallon, followed by Hawaii, Washington, Nevada, and Oregon. In contrast, Texas has the lowest prices at $3.95 per gallon, with Indiana and other states following closely behind. Diesel prices, which are crucial for heavy-duty and commercial vehicles, are also at record highs. As of Thursday, diesel averaged $6.51 per gallon, up nearly $3 from the same time last year. The rising cost of diesel has ripple effects on the economy and consumers, as it influences transportation costs and, in turn, the prices of goods and services. GasBuddy, a gas-price tracking site, explained that diesel powers much of the U.S. economy, including freight trucks, trains, and construction equipment. As diesel prices climb, so do the costs of moving goods and services, often leading to higher prices for consumers. President Donald Trump has previously expressed indifference to the rising gas prices, stating that high fuel costs are a small price to pay for preventing Iran from developing nuclear capabilities. However, Trump recently suggested he might consider banning diesel exports to reduce domestic prices. This potential policy shift could have significant implications for both the energy market and the broader economy.
