FX.co ★ US Core PPI Rebounds in December, Signaling Renewed Pipeline Price Pressures

The core Producer Price Index (PPI) in the United States accelerated in December 2025, rising 0.7% month-over-month after remaining flat in October at 0.0%. The latest data, updated on 30 January 2026, underscore a renewed pickup in underlying producer prices after a period of stability.

Measured on a month-over-month basis, the December increase marks a notable shift from the stagnation seen in October, when core producer prices showed no change compared with the prior month. As core PPI excludes more volatile components, the rebound suggests that underlying cost pressures at the producer level have strengthened into year-end.

This sharper monthly gain in December may draw attention from investors and policymakers monitoring whether producer-level inflation is re-emerging after earlier signs of moderation. The comparison framework highlights that while October showed no change versus the previous month, December’s 0.7% rise points to a firmer upward trajectory in core production costs heading into 2026.
