December PPI’s Broad-Based Mirage: Services +0.7% driven by trade margins +1.7% and machinery wholesaling +4.5%

In the official press release dated 2026-01-30, December’s Producer Price Index is sold as a “broad-based” services story. The data disagrees. The 0.7% rise in services is heavily concentrated: two-thirds comes from trade services margins jumping 1.7%, and over 40% of the entire services gain is traceable to a single line—machinery and equipment wholesaling margins up 4.5%. Meanwhile, the “goods unchanged” headline is balanced on falling energy, masking underlying firmness elsewhere.

Here’s what the data reveals:
- Headline final demand rose 0.5% in December, up from 0.2% in November and 0.1% in October—a clear Q4 re-acceleration.
- Core pressure persists: final demand less foods, energy, and trade services advanced 0.4% in December and ran 3.5% in 2025 (vs 3.6% in 2024).
- Goods “flat” is misleading: goods ex-food and energy +0.4%, while energy -1.4% and foods -0.3% did the flattening.
- Upstream heat is building: unprocessed goods +2.3% (unprocessed energy +5.5%, natural gas +34.8%), intermediate services +0.7%, and Stage 2 intermediate demand +1.4% with goods inputs +2.6%.
- Revisions to August–November and pending FD–ID allocation updates cloud clean deceleration narratives and raise revision risk—especially for volatile trade margins.

Q4 Momentum at a Glance

Broad-Based? Not Quite—Margins Did the Heavy Lifting

The headline “broad-based” services increase leans hard on trade services, not ubiquitous cost pressure. December’s +0.7% services rise is dominated by +1.7% in trade margins, with machinery and equipment wholesaling margins up 4.5% accounting for more than 40% of the entire services increase. Add contributions from portfolio management and guestroom rentals, and you’ve got a margin-centric story that’s inherently volatile.

The volatility is on display in Q4: trade services printed -0.8% in October, -0.6% in November, then +1.7% in December. If you follow the margins, you follow the headline. That’s a fragile basis for declaring broad-based services momentum—especially with wired telecom down 4.4%, a reminder that not all service categories are participating.

Revisions compound the uncertainty. The release flags revisions from August through November, without a side-by-side. Given that trade services can swing 1%+ in a month, December’s big pop is a prime candidate for recalibration. Investors should also note the materials’ warning about updated FD–ID allocations tied to the 2017 Input–Output Accounts. Changes in category weights can subtly recast the goods-versus-services narrative around year-end, complicating trend comparisons.

Goods “Unchanged” — Except Where It Counts

December’s final demand for goods is “unchanged,” but the composition tells a different story. Goods ex-food and energy rose 0.4% while energy fell 1.4% and foods -0.3%. The flat headline rests on energy’s downdraft—not a broad stall in goods pricing.

Under the hood:
- Non-energy goods showed life: nonferrous metals +4.5%; increases also cited for residential natural gas, motor vehicles, soft drinks, and aircraft.
- Energy’s plunge did the masking: diesel -14.6%, with gasoline and jet fuel also falling. Good for transport margins today—less reassuring for the sustainability of “flat goods” if upstream energy reverses.

This is a goods mix that’s anything but quiet. When the steady ex-energy rise is offset by volatile energy declines, the headline can look becalmed while underlying prices firm. That’s not disinflation; that’s composition.

Core Momentum vs the Deceleration Spin

The release emphasizes that final demand rose 3.0% in 2025 versus 3.5% in 2024, implying cooling. But the core tells a stickier tale: final demand less foods, energy, and trade services increased 0.4% in December and 3.5% for 2025, just a tick below 3.6% in 2024. Meanwhile, monthly momentum accelerated in Q4: 0.1% → 0.2% → 0.5% on the headline.

This is the classic mismatch between year-over-year optics and month-over-month reality. The y/y deceleration may be accurate, but the Q4 impulse is moving the other way. Add the December emphasis on margins and rents—like gross rents for retail properties up 10.1% within intermediate services—and the services story looks less like broad cost inflation and more like price-sensitive, revision-prone categories doing the work.

Note the context drift: prior narratives around August “edged down 0.1%” and September “increased 0.3%” have been revised, and the September 2025 release was delayed over five weeks by a funding lapse. Continuity has been messy; confidence in the neat deceleration storyline should be equally so.

Pipeline Pressures: The Heat Is Upstream

Upstream indicators are running hotter than the final demand headline:
- Unprocessed goods +2.3%, with unprocessed energy +5.5% and natural gas +34.8%.
- Processed goods -0.1%, dragged by processed energy -2.4%, even as utility natural gas and electric power advanced.
- Intermediate services +0.7%.

By production flow, the pressure points line up where pass-through risk tends to originate:
- Stage 2 +1.4% (goods inputs +2.6%, services inputs +0.5%)
- Stage 4 +0.6% (services inputs +0.9%)
- Stage 1 +0.5% (services inputs +1.0%, goods inputs -0.1%)
- Stage 3 +0.2%

That mix—rising Stage 2 goods inputs, rising Stage 4 services inputs—often precedes pressure in finished-services pricing and utilities. Pair residential natural gas up at final demand with natural gas +34.8% upstream, and you have a plausible pass-through channel the headline framing downplays.

What This Means for Markets

• Rates and breakevens: A 0.4% core ex F/E/Trade in December and 3.5% core for 2025 argue against a quick disinflation victory. The Q4 re-acceleration (0.1% → 0.2% → 0.5%) supports sticky inflation risk. Front-end yields may stay sensitive to upside surprises, and breakevens have room to defend recent levels if upstream pressures persist.

What to Watch Next

• Revisions to December’s trade services (+1.7%) and the concentration in machinery and equipment margins (+4.5%).

• FD–ID allocation changes tied to 2017 IO updates—assess whether sector contributions shift, particularly around goods versus services.

• Pass-through barometers: utility natural gas, electricity, and service-heavy categories sensitive to Stage 2 goods inputs +2.6% and Stage 4 services inputs +0.9%.

• Whether the Q4 acceleration carries into January, or if December’s margin pop mean-reverts.

The headline told you goods were flat and services were broadly firm. The data showed margin whipsaws, a quietly rising core, and upstream heat that hasn’t finished testing downstream prices. Don’t trade the headline—trade the composition, and stay nimble where revisions and reweightings can redraw the map overnight.
