Latest update: 5.5 percent — May 12, 2021

The Atlanta Fed's sticky-price consumer price index (CPI)—a weighted basket of items that change price relatively slowly—increased 5.5 percent (on an annualized basis) in April, following a 3.5 percent increase in March. On a year-over-year basis, the series is up 2.4 percent.

On a core basis (excluding food and energy), the sticky-price index increased 5.7 percent (annualized) in April and its 12-month percent change was 2.3 percent.

The flexible cut of the CPI—a weighted basket of items that change price relatively frequently—increased 23.1 percent (annualized) in April and is up 10.3 percent on a year-over-year basis.
