Published by 11:00 a.m. (ET) on the day of the CPI release, the sticky price index sorts the components of the consumer price index (CPI) into either flexible or sticky (slow to change) categories based on the frequency of their price adjustment.
The Atlanta Fed's sticky-price consumer price index (CPI)—a weighted basket of items that change price relatively slowly—increased 6.7 percent (on an annualized basis) in January, following a 4.2 percent (revised) increase in December. On a year-over-year basis, the series is up 4.6 percent.
On a core basis (excluding food and energy), the sticky-price index increased 6.8 percent (annualized) in January, and its 12-month percent change was 4.6 percent.
The flexible cut of the CPI—a weighted basket of items that change price relatively frequently—decreased 4.6 percent (annualized) in January and is down 0.9 percent on a year-over-year basis.
Note: All sticky-price and flexible-price series have been revised for the past five years due to new seasonal factors released by the BLS on February 9. In addition, we've changed our treatment of updating relative importance values to more closely align with BLS methods. This update results in modest revisions going back to the beginning of the series.
