The lack of progress in 12-month headline and core PCE inflation in 2025 is a concern because year-over-year growth in the rent components of PCE are currently downwardly biased. These components — which capture tenant rents and imputed rents of owner-occupied housing — make up over 15 percent of the headline inflation measure and nearly 20 percent of the core inflation measure. The downward bias in measuring year-over-year rent growth stems from the government shutdown late last year, which led statistical agencies to assume zero rent growth in October 2025. This issue will be resolved in April 2026 when the housing units that should have been measured in October will be reassessed by the Bureau of Labor Statistics.

In the meantime, price indexes that exclude rents arguably provide a less biased view of inflation progress. One such index is the price index for services excluding energy and housing (also called "core services ex housing"). Figure 3 below shows the three-month, six-month and 12-month annualized growth rates of the PCE core services ex housing price index. December saw the three-month rate rise to 3.9 percent, higher than the six-month rate of 3.7 percent and the 12-month rate of 3.3 percent. This ordering suggests price pressures in nonhousing core services worsened over the course of the year. By comparison, during the 2015-19 prepandemic period, all three growth rates were close to 2 percent.
