The Consumer Price Index (CPI) rose 2.4% on a year-over-year basis in September, up from a 1.9% increase in August.
On a year-over-year basis, gasoline prices fell less in September (-4.1%) compared with August (-12.7%) due to a base-year effect, leading to an acceleration in headline inflation. Excluding gasoline, the CPI rose 2.6% in September, after increasing 2.4% in August.
A slower year-over-year decline in prices for travel tours (-1.3%) and a larger increase in prices for food purchased from stores (+4.0%) also contributed to the upward pressure in the all-items CPI in September.
The CPI rose 0.1% month over month in September. On a seasonally adjusted monthly basis, the CPI was up 0.4%.
