Food for thought.
Historically, the CPI has run hotter than the PCE, which the Fed targets.
That relationship has flipped, notably on core CPI and PCE. The nonfood and non-energy measure of PCE are a full percent HIGHER than core CPI.
Why?
First, are shelter costs, which have cooled. They have a larger weight in the core CPI than core CPI.
Second, are some measurement issues that the BEA is working to improve and will shave 0.2% give or take to Y/Y PCE with benchmark revisions next week.
Third, and most important. The PCE better captures health car costs when they are rising rapidly than the CPI. Those costs are rising so fast that many employers have slowed wage gains to deal with the jump.
We have not seen the gap anywhere near its current spread since 1983.
Those costs are particularly hard for the Fed to reign-in. Instead, it must hammer other more cyclically sensitive prics to offset those increases.
That is more painful than the near immaculate disinflation the Fed laid out with the press conference and forecasts after it raised rates for the first time since 2023 in September.
