The Sticky Price CPI sorts the components of the consumer price index (CPI) into either flexible or sticky categories based on the frequency of their price adjustments. A good or service is called “sticky” if its price is resistant to change.

The Sticky CPI is the most in-depth version of the core CPI. It does not limit the exclusions to only food and energy like the core CPI. It does not have a set number of exclusions like the PCE price index. The Sticky CPI reflects price trends that are expected to persist.
