The U.S. Bureau of Labor Statistics reported that the Consumer Price Index for All Urban Consumers rose 0.6 percent in September 2026 on a seasonally adjusted basis. Over the 12 months ending in September, the index rose 3.7 percent on a not-seasonally-adjusted basis, the bureau said.
The index for all items less food and energy — commonly referred to as core CPI — rose 0.3 percent in September on a seasonally adjusted basis, and was up 2.6 percent over the year, not seasonally adjusted, according to the release.
The bureau attributed much of the monthly increase to energy prices, stating that "the index for gasoline rose 9.1 percent in September, accounting for over half of the monthly all items increase." Over the 12-month period, it said "the energy index increased 20.4 percent... due in large part to the index for gasoline rising 34.2 percent."
Shelter costs continued to rise: the bureau said "the shelter index rose 0.4 percent in September after rising 0.3 percent in August," with the shelter index up 3.2 percent over the year.
The food index was unchanged in September on a seasonally adjusted basis, the bureau said, though it rose 2.5 percent over the preceding 12 months.
The release reports the measured price changes for the month and the year; it includes no assessment of future price trends or monetary policy.
