Is US inflation re-accelerating in 2026?

Yes, on the Fed's own gauge. Core PCE - the measure the Fed targets at 2% - is at 3.3% and re-accelerating, and has now spent 62 straight months above target (the 25-year pre-Covid average was 1.7%). Outside Covid, it was last this high in April 1992.

The pipeline points higher: producer prices (PPI final demand at 6.4%, core PPI 4.9%) are the hottest in the modern series outside Covid, and PPI is running about 2.2 points ahead of CPI - so producers are absorbing the bigger share now (margin compression), with consumer pass-through likely to follow. The consumer is already stretched: gasoline near $4.65 and 90+ day delinquencies on consumer debt at 3.4%, past the 2007 mark.
