The annual inflation rate in the US likely remained at 2.7% in December 2025, while the core rate probably edged up to 2.7% from 2.6% in November which was the lowest level since early 2021. On a month-over-month basis, headline CPI is expected to have increased by 0.3%, with core CPI also seen rising by 0.3%, driven mainly by higher goods prices. Month-over-month figures for November were not published by the BLS, as the agency was unable to collect data during the government shutdown. The December report may point to a reversal of the downward inflationary pressures observed in November; however, concerns over data quality remain as distortions linked to the shutdown may still be affecting the figures.
