US Inflation: November CPI—Disinflation or Data Mirage?

US Inflation: November CPI—Disinflation or Data Mirage?
The markets have spent the last 48 hours in a state of caffeine-fueled euphoria. On paper, the November Consumer Price Index (CPI) print of 2.7%, a cooling from September’s 3.0%, looks like a decisive victory for the Federal Reserve. It is the kind of number that makes a soft landing feel less like a pilot’s prayer and more like an impending reality.

But at The Saturday Economist, we prefer to look under the hood. And right now, the engine of the US economy is emitting a very strange rattle. The November report is not a clean read; it is a "Franken-report," stitched together from missing pieces and statistical guesswork. Due to the 43-day federal government shutdown, October data was never collected. For the Bureau of Labor Statistics (BLS), this meant the "gold standard" of economic data had to be replaced by "bridging"—a polite term for imputation and technical extrapolation.


The "Shutdown Distortion" Factor : The headline 2.7% figure is arguably the least reliable data point of 2025. Because BLS field workers were sidelined during the shutdown, they relied heavily on proxies.

The most glaring issue lies in Shelter. Comprising roughly one-third of the total CPI, shelter costs were effectively "zeroed out" for the October portion of the calculation. This creates a mathematical downward bias. While the report suggests rents and housing costs are cooling, the reality on the ground, marked by rising property taxes and insurance premiums, tells a different story.

Furthermore, field work only resumed on November 14. This means the "November" report is effectively a snapshot of the month’s second half, missing the early-month consumer behavior that often sets the tone for the holiday quarter. We aren't looking at a full month of data; we are looking at a polaroid taken in a dark room with a failing flash.


The Kitchen Table Disconnect: While the "official" numbers cooled, the lived experience of the US consumer remains stubbornly hot. There is a widening divergence between technical disinflation and "kitchen table" inflation.

Consider the Energy and Utilities sector. Despite the headline drop, the energy index surged 4.2% year-over-year. Dig deeper, and it gets worse: electricity and natural gas are up 6.9% and 9.1% respectively. If you are a manufacturer or a homeowner, "disinflation" is a word used by people who don't pay your bills.

Even the cooling in Core CPI (ex-food and energy), which slowed to 2.6%, requires an asterisk. This was largely driven by a deceleration in discretionary categories like used vehicles and apparel. Retailers, fearing a shutdown-induced slump, slashed prices to move inventory. This is "desperation disinflation," not a systemic cooling of the services sector, which remains propped up by elevated wage growth.


The Fed is Flying with a Cracked Windshield: For Jerome Powell, this report is a strategic nightmare. The Fed’s preferred gauge, the Personal Consumption Expenditures (PCE) index, is also facing disruptions. The Fed is essentially flying a jumbo jet with a cracked windshield and a flickering GPS.

We expect the FOMC to treat this report as a technical outlier. While "doves" are already using the 2.7% figure to demand aggressive rate cuts in 2026, the Fed cannot credibly claim "mission accomplished" when nearly half the data in this report is imputed.

However, there is a pivot coming but not for the reason the markets think. With the labor market showing genuine signs of fatigue (unemployment hitting a 4-year high of 4.6%), the Fed is more likely to cut rates in January due to growth fears rather than inflation success. They aren't cutting because they won; they are cutting because the floor is starting to creak.


The Analyst's Verdict: The November data is a technical gift for equity markets but a strategic headache for economists. We are seeing a "catch-down" effect where the lack of October data artificially accelerated the path to the 2% target.

We advise strategic caution. The primary risk is a "snap-back" in the December or January data. Once full-month data collection stabilizes, we expect a "hotter" corrective read that could catch a jubilant market off-guard, forcing the Fed to pause its easing cycle just as investors are betting on a free-fall in rates.

In short: the trend is your friend, but the data is a stranger. Don't trust it with your house keys just yet.
