Inflation Guy’s Overview of US CPI (December 2025)

Reflecting on Last Month's CPI Confusion

As we kick off this month, it's worth recalling the chaos surrounding last month's Consumer Price Index report. The November figures were immediately questionable, and it quickly became clear that the Bureau of Labor Statistics had presented two-month changes that actually reflected just a single month's shift. In particular, it appeared that for categories like housing, the BLS treated October as unchanged, effectively stretching a one-month change across two months. This led to some glaring inconsistencies in the data.
