Published by noon (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) measure—the measure of the weighted basket of goods consumers purchase that change prices relatively infrequently—rose 0.8 percent (annualized) in April, following 1.8 percent growth in March. The 12-month change in the index was 2 percent.
The sticky price index increased 0.4 percent (annualized) on a core basis (excluding food and energy) in April, and the 12-month index was 1.9 percent.
The flexible cut of the CPI—a weighted basket of goods that change price relatively frequently—declined at a 15 percent annualized pace in April. The flexible CPI is now 0.8 percent below year-ago levels.
