Producer Prices Jump 0.81% in December — The Biggest Monthly Gain Since March

Producer prices surged 0.81% in December, the sharpest monthly increase in nine months and more than double what economists expected. Year-over-year producer inflation now sits at 2.38%, marking the fifth consecutive month of acceleration from the summer lows.

Here’s what makes this reading particularly noteworthy: producer price spikes typically flow through to consumer prices within 2-3 months, which means January and February CPI readings could run hotter than the Federal Reserve wants to see. The December jump was broad-based too — not driven by a single volatile category like energy, but spread across goods and services. That suggests underlying inflationary pressures are building, not just temporary price shocks working through the system.

This fits a pattern we’ve been tracking since August: producer inflation bottoming out and now climbing steadily higher. It’s the mirror image of what happened in early 2023, when falling producer prices gave the Fed confidence that consumer inflation would follow suit. Now we’re seeing the reverse dynamic unfold. The timing matters because the Fed has been signaling they’re nearly done with rate cuts — data like this reinforces that pause.

Many professional investors view rising producer prices as a yellow light for bond markets, since higher wholesale costs eventually squeeze either corporate margins or consumer wallets. Historically, when PPI acceleration coincides with tight labor markets and steady consumer spending, investors have rotated toward sectors that can more easily pass through higher costs — think utilities, consumer staples, and companies with strong pricing power.

Bottom Line: Producer prices are telling us the same story as wages, services inflation, and housing costs — underlying price pressures are reaccelerating. The Fed’s “soft landing” isn’t in jeopardy yet, but the landing is getting bumpier.
