Inflation from core services excluding housing—or “supercore” inflation—increased in January, contributing 0.24 percentage points to core Consumer Price Index (CPI) inflation, up from 0.11 percentage points in December (green bars). Of the three primary components of core CPI inflation—core goods, housing services, and supercore—supercore inflation is the most labor intensive and therefore especially sensitive to nominal wage increases. Although nominal wage increases moderated during 2023, they remain above their pre-pandemic levels, continuing to put upward pressure on supercore inflation.

Note: This chart replaces an earlier version to correct the calculation of supercore inflation.
