National gasoline prices rose to 4.47 dollars per gallon on September 17. Geopolitical tensions in the Middle East drive the increase against seasonal trends.

The national average for regular gasoline reached 4.47 dollars per gallon on September 17. This figure marks a significant jump from 4.37 dollars the previous day and 4.28 dollars one week earlier. Data from GN auto markets/energy: gasoline prices confirms the upward trajectory. Prices are rising despite typical seasonal demand drops after Labor Day.

Crude oil averages approximately 100 dollars per barrel. This elevation stems from geopolitical tensions and energy supply constraints. The national diesel average hit 6.40 dollars per gallon on the same date. Higher diesel costs often translate into increased shipping expenses for consumer goods.

Regional price variations remain stark

California recorded the highest national average at 6.09 dollars per gallon. Washington state followed with 5.58 dollars, while Nevada averaged 5.19 dollars. Indiana showed one of the lowest rates at 3.92 dollars. Texas, Mississippi, and Louisiana also kept averages below the 4.00 dollar threshold.

Pipeline disruptions impact global supply routes

Conflict in the Middle East threatens the Strait of Hormuz. This route handles roughly 20 percent of the world's oil supply. A drone attack forced Saudi Arabia to shut its East-West pipeline. The 745-mile line serves as a critical bypass for Hormuz disruptions.

Political debates focus on fuel costs

Gas prices have become a central issue for the November midterm elections. Democrats plan to highlight the cost increase to regain power. President Trump argues that higher prices are a necessary trade-off for security. He stated that fuel costs will eventually decrease.
