US drivers are facing significantly higher fuel costs, with the national average price for regular gasoline reaching $4.33 a gallon, a 34.2% increase from a year ago. This surge in gasoline prices contributed to a 9.1% rise in September alone, pushing overall consumer inflation to 3.7% annually. The broader energy index has climbed 20.4% over the past year. Diesel prices have also seen a substantial increase, up approximately 72% year-over-year to $6.30 a gallon. These rising energy costs are attributed to disruptions in global oil supplies amid the conflict involving Iran and restrictions on Middle Eastern shipping routes. Heating oil prices have also climbed sharply, with the national average at $6.04 a gallon, and electricity and utility gas costs have also seen annual increases.
