Inflation's Monthly Reality Check
Cooling Headline, Warmer Core: January CPI’s 0.3% Core Re-Acceleration Hides in the Footnotes
On 2026-02-13, the Bureau of Labor Statistics announced that January CPI rose 0.2% month over month (SA) and 2.4% year over year (NSA)—a tidy cooldown from December’s 2.7%. The release leaned on “shelter was the largest factor” and “energy fell 1.5%,” but the internals told a more stubborn story: core accelerated to 0.3%, services less energy services jumped to 0.4%, and transportation services surged 1.4%. Meanwhile, the report invoked five years of seasonal adjustment revisions—without quantifying their impact—and showed October/November 2025 values for some categories while declaring those months “not available” for others.
Here’s what the data reveals:
- Headline cooled to 2.4% YoY, but underlying pressure firmed: core +0.3% MoM, services ex-energy +0.4% MoM, transportation services +1.4% MoM; airline fares +6.5% MoM
- Energy’s -1.5% MoM drop was gasoline-led (-3.2%), while utilities quietly bit: natural gas +1.0% MoM (+9.8% YoY), electricity -0.1% MoM (+6.3% YoY)
- Goods disinflation persisted: used cars -1.8% MoM (YoY -2.0%); “commodities less food and energy commodities” flat again
- NSA vs SA optics matter this month: NSA +0.4% vs SA +0.2%, with newly revised seasonal factors shaping the headline
- Transparency gaps: five years of revised seasonal factors but no before/after detail; inconsistent Oct/Nov 2025 data display across series undermines comparability
Cooling Headlines, Heating Underneath
The headline does cool: 2.7% YoY in December to 2.4% in January. But the month-over-month engine—the one the Fed actually drives by—revved. Core CPI rose 0.3% (vs 0.2% in December). Services less energy services climbed 0.4% (vs 0.3%), and transportation services spiked 1.4% (vs 0.4%). That’s not the profile of a clean disinflation glide path.
January’s composition also shifted in ways that matter for persistence:
- Shelter +0.2% MoM (YoY +3.0%) decelerated from December, yet remained above headline YoY.
- Services breadth expanded: airline fares +6.5%, personal care +1.2%, recreation +0.5%, communication +0.5%.
- Goods stayed tame: used cars -1.8%, new vehicles +0.1%, apparel +0.3%, household furnishings -0.1%.
The monthly re-acceleration of core and core services, paired with sticky shelter and broad service increases, is the uncomfortable center of gravity the headline avoids.
January vs December: Where Momentum Actually Shifted
| Series (MoM, SA) | Dec 2025 | Jan 2026 | Direction |
|---|---|---|---|
| Headline CPI | 0.3 | 0.2 | Down |
| Core CPI | 0.2 | 0.3 | Up |
| Services less energy services | 0.3 | 0.4 | Up |
| Shelter | 0.4 | 0.2 | Down |
| Energy | 0.3 | -1.5 | Down (gasoline-led) |
| Transportation services | 0.4 | 1.4 | Up sharply |
| Used cars and trucks | -0.9 | -1.8 | Down further |
| Food | 0.7 | 0.2 | Down |
The pattern is classic: goods disinflation remains intact, but services—where wages and capacity constraints live—are doing the heavy lifting.
Shelter Got Top Billing. Services Wrote the Script.
The release calls shelter “the largest factor” behind the monthly gain. That’s mathematically plausible in weight terms, but it buries the plot: non-shelter services were loud in January. Within transportation services alone, airline fares jumped 6.5%, while overall transportation services rose 1.4% despite the BLS flagging declines in used cars (-1.8%) and motor vehicle insurance (-0.4%). In other service niches, personal care (+1.2%), recreation (+0.5%), and communication (+0.5%) all pushed higher.
This breadth matters. When service categories outside shelter accelerate together, the implication is stickier underlying momentum. It’s also harder for headline disinflation to persist if goods can’t continue doing all the work.
Energy’s Optical Illusion
A -1.5% monthly drop in energy reads like relief—until you open the hood. Gasoline’s -3.2% MoM (-7.5% YoY) did the heavy lifting, while what households actually pay monthly in utilities moved the other way: natural gas +1.0% MoM (+9.8% YoY) and electricity -0.1% MoM (+6.3% YoY). The average household’s bill cares more about utility tariffs and winter heating than pump prices in January.
In short:
- Gasoline is delivering disinflation optics.
- Utilities are delivering the bills.
Treat the “energy fell” headline as a gasoline headline. Utility inflation remains a live wire for consumers and a risk for services margins where energy pass-through is less flexible.
Revisions, Gaps, and the SA/NSA Split
Two transparency issues complicate interpretation:
1) Seasonal adjustments: The BLS revised seasonal factors across five years—standard practice—but provided no before/after comparisons. In a month where NSA rose 0.4% and SA rose 0.2%, the revised seasonal recipe materially shapes the headline. Without a quantification of revisions, it’s hard to parse how much of January’s “cooler” print is math vs market reality.
2) Data availability inconsistencies: The note says “Oct and Nov 2025 data values are not available due to the 2025 lapse in appropriations,” yet Table A shows values for some series (used cars, new vehicles) while using dashes for others (transportation services, services less energy services). That unevenness muddies comparisons and can bias narrative emphasis toward categories with filled gaps.
Narrative vs Data: The Gaps That Matter
| BLS Framing | Data Reality | Why It Matters |
|---|---|---|
| “Inflation cooled to 2.4% YoY; +0.2% MoM.” | Core +0.3%, services ex-energy +0.4%, transportation services +1.4%. | Underlying momentum firmed even as YoY cooled. |
| “Shelter was the largest factor.” | Broad services rose; airline fares +6.5%, personal care +1.2%. | Inflation breadth extends beyond shelter. |
| “Energy fell 1.5%.” | Gasoline down; utilities still hot: nat gas +9.8% YoY, electricity +6.3% YoY. | Household energy pressure persists. |
| “Seasonal factors revised.” | No quantification; Oct/Nov gaps inconsistent. | Trend visibility is impaired. |
What This Means for Markets
- Rates and Fed path: January’s core 0.3% and services ex-energy 0.4% nudge the risk distribution away from an early or aggressive easing cycle. Expect policymakers to lean into “higher-for-longer until services cool.” Market-implied odds for front-loaded cuts should fade on prints like this; curves may re-steepen via the front end.
- Breakevens and TIPS: Headline softness from gasoline can cap near-term breakevens, but the stickiness in core services argues for owning intermediate TIPS or core-inflation-sensitive breakeven exposure on dips. The services impulse is not dead.
- Equities:
- Credit: Sticky services inflation can keep real incomes under mild pressure, a mixed setup for consumer ABS: supportive for auto credit via affordability improvements, but a headwind where utility/insurance costs remain elevated.
- Utilities and energy: The divergence between gasoline and utilities underscores a long trade in regulated utilities with tariff pass-through and a continued short leash on fuel-sensitive, price-taking industrials.
Looking Ahead: What to Watch
- February core services: Do we sustain 0.4% MoM in services ex-energy, or was January a one-off lift from travel and a few service niches? Persistence would cement the “patience” case for the Fed.
- PCE translation: Core CPI’s 0.3% doesn’t auto-convert to core PCE, but the services breadth usually bleeds through. Watch for February’s PCE services supercore.
- Seasonal revision fallout: Any supplemental detail from BLS on revisions would sharpen trend inference. In the absence of transparency, lean on multi-month averages and alternate cross-checks.
- Transport services mix: With airline fares +6.5%, monitor whether February normalizes or if yield management is tightening across carriers.
The investing takeaway is straightforward: the story being sold is “cooling.” The story being lived by prices is “re-accelerating where it counts.”
The Investor Takeaway
Don’t trade the gasoline headline. Trade the core engine. January’s CPI puts the burden of proof back on disinflation. Position with:
- Modestly reduced duration at the front end; favor carry in the belly if you need rates exposure.
- Selective TIPS/breakeven add on softness—we still see services stickiness as an underpriced tail.
- Tilt toward service sectors with demonstrable pricing power and disciplined capacity (travel, select communications, personal services).
- Stay cautious on residual-sensitive auto exposures as used car deflation grinds on.
- For consumer cyclicals, assume utility inflation quietly taxes wallets even as the pump offers relief.
The BLS gave markets a cooling headline on 2026-02-13. The data gave investors a hotter core and broader services pressure. In this tape, the smart money prices the momentum, not the mood.
