The Consumer Price Index rose at an annual rate of 3.7% in September, marking a sharp acceleration in U.S. inflation driven primarily by soaring energy costs. The Labor Department's data reveals that price pressures remain stubborn just weeks before the midterm elections, challenging the Federal Reserve's recent trajectory of holding rates steady.
Economists surveyed by FactSet had forecast a more moderate 3.6% annual increase for the month. The actual figure represents a pickup from the previous two months, during which inflation held steady at an annual pace of 3.4%. Core CPI, which excludes volatile energy and gas categories, also accelerated, rising 2.6% from a year ago compared to a 2.4% rate in August. This core figure exceeded the 2.5% forecast provided by economists.
The surge in headline inflation is directly linked to the war in Iran and Russia's ongoing conflict with Ukraine, which have sent energy prices sharply higher since the start of the year. The Labor Department attributed more than half of the monthly CPI increase to gasoline prices, which jumped 9.1% in September from the prior month. On an annual basis, energy prices rose 20.4%, while gasoline specifically spiked 34.2%.
Current pump prices remain elevated despite a slight recent cooling trend. AAA reported that the national average for a gallon of gasoline stood at $4.33 on Wednesday, a significant increase from $2.98 before the war began. Diesel prices hit a record high in late September, with the national average reaching $6.29 per gallon. Higher diesel costs complicate logistics by increasing the expense of transporting goods across the U.S., a factor that often translates into higher prices for everyday consumer items such as groceries.
Market analysts view the data as difficult to downplay. Adam Crisafulli, head of Vital Knowledge, stated in a note to investors that the CPI was "clearly hot" and that there were few ways to sugarcoat the results. He emphasized that energy played a "huge role" in the numbers and warned that prices may not decline soon as conflicts in the Middle East and Ukraine escalate. Crisafulli noted that prolonged high energy prices are beginning to seep into the broader economy.
Consumer sentiment reflects this economic reality. A CBS News poll released earlier this month found that nine in 10 Americans identify prices as the most important factor shaping their views of the economy.
