The Consumer Price Index for All Urban Consumers rose 0.6% in September on a seasonally adjusted basis, lifting the 12-month headline rate to 3.7% from 3.4% in August, the U.S. Bureau of Labor Statistics reported. A 9.1% jump in gasoline prices drove more than half of the monthly increase. Core inflation, which excludes food and energy, rose 0.3% in the month and 2.6% over the year.

The Consumer Price Index for All Urban Consumers increased 0.6 percent in September on a seasonally adjusted basis, after rising 0.4 percent in August, the U.S. Bureau of Labor Statistics reported. Over the last 12 months, the all-items index increased 3.7 percent before seasonal adjustment - accelerating from the 3.4-percent annual pace reported in August. Energy was the dominant driver. The energy index rose 5.2 percent in September following a 2.1-percent increase in August, and the gasoline index jumped 9.1 percent, accounting for more than half of the monthly all-items increase. Over the past year, energy prices are up 20.4 percent. The shelter index rose 0.4 percent in September after a 0.3-percent rise in August. The food index was unchanged, as a 0.2-percent increase in food away from home offset a 0.1-percent decline in food at home. Core inflation - all items less food and energy - rose 0.3 percent for the second consecutive month and 2.6 percent over the past 12 months, up from a 2.4-percent annual pace in August. The persistence of underlying price pressures alongside the energy shock keeps inflation running well above the Federal Reserve's 2 percent target ahead of its October meeting.
