The U.S. Consumer Price Index rose 0.6% on a seasonally adjusted basis in September, accelerating from 0.4% in August. Gasoline prices rose 9.1% and accounted for more than half of the monthly increase; the 12-month all-items inflation rate was 3.7% before seasonal adjustment.

U.S. consumer prices rose 0.6% on a seasonally adjusted basis in September, faster than the 0.4% increase in August, as gasoline prices surged and energy costs continued to climb, according to the Bureau of Labor Statistics. The all-items index was 3.7% higher over the 12 months through September, before seasonal adjustment.

The gasoline index jumped 9.1% during September, accounting for more than half of the monthly increase in the all-items Consumer Price Index, the BLS said. The broader energy index rose 5.2% over the month, following a 2.1% increase in August. Those figures show that energy was the main reported source of the faster monthly inflation reading.

Price increases were not limited to energy. The shelter index rose 0.4% in September, compared with 0.3% in August. The index for all items less food and energy increased 0.3% for a second consecutive month, indicating that the monthly measure excluding those two categories did not accelerate between August and September.

The BLS also reported monthly increases in indexes for recreation, used cars and trucks, education, airline fares, medical care and apparel. Communication was among the small number of major indexes that declined. The supplied report does not give the size of those individual changes or a September food-index figure.

The developmentThe Bureau of Labor Statistics reported that U.S. consumer prices rose faster in September than in August, with gasoline driving much of the monthly increase.

Energy Drove September’s Price Increase

The report matters to households because gasoline contributed more than half of the monthly CPI increase, while the overall index rose faster than it did in August. A sharp change in fuel costs can affect what consumers pay directly at the pump and can add to expenses for businesses that rely on transport, although the figures provided do not quantify those wider effects.

The figures also show a difference between the headline monthly movement and the measure excluding food and energy: the core index remained at 0.3% for the month, while the all-items measure accelerated. That distinction can help readers understand which reported categories drove the change, but the data alone do not establish how prices will move in coming months or what caused the gasoline increase.

August and September CPI Readings

The BLS reported that the all-items CPI rose 0.4% in August and then 0.6% in September, both figures measured on a seasonally adjusted monthly basis. The September 12-month increase of 3.7% is a separate, unadjusted measure; it compares the index with its level 12 months earlier and should not be confused with the one-month change.

September’s energy increase also followed a rise in August: the energy index moved from up 2.1% to up 5.2% month to month. The report provides the category movements cited above, but not additional detail on the causes of energy-price changes, regional patterns or how the figures affect particular household budgets.

“The Consumer Price Index increased 0.6% on a seasonally adjusted basis in September after rising 0.4% in August.”

What the CPI Report Does Not Show

The supplied report does not detail why gasoline prices rose, whether the increase will persist, or how prices varied across regions. It also does not provide the individual percentage changes for most categories, a September food-index figure, or information about how the CPI reading may affect future policy decisions. The September data describe price changes during that month; they do not establish a future trend.

The 3.7% 12-month figure is reported before seasonal adjustment, while the monthly figures are seasonally adjusted. The report does not provide a full breakdown of the annual increase by category, so it cannot show from these figures alone how much energy contributed to the year-over-year rate.

Further CPI Details and Trends

Readers can compare the September figures with subsequent monthly CPI releases to see whether the increase in energy costs continues and whether other categories change pace. The next data point will help establish whether September’s faster headline reading was a one-month movement or part of a broader pattern; that cannot be determined from this report alone.

For now, the confirmed development is the September increase: the all-items index rose 0.6% month to month, gasoline rose 9.1%, and the 12-month all-items rate was 3.7% before seasonal adjustment. Any explanation of what drove fuel prices or prediction of the next CPI reading remains outside the details provided.
