The number was zero. Not a slight miss, not a modest deceleration, not a soft landing. Zero. US retail sales for December 2025 showed no growth at all — a 0.0% month-over-month change that landed approximately 40 basis points below what Wall Street economists had projected. In the context of an economy that had been recording 4.4% annualized GDP growth as recently as the third quarter of 2025, a flat retail sales print at the end of the year raises a question that markets are just beginning to grapple with: is the American consumer finally running out of runway?
The retail sales data was among the economic reports delayed by the federal government shutdown in late 2025. Its release this week, alongside the December trade deficit and other government statistics that were similarly held hostage by the funding lapse, provided a retroactive window into economic conditions at year-end. What that window showed was not the picture of resilient consumer spending that had characterized most of 2024 and the first three quarters of 2025. It was a consumer who had stopped.
What Happened in December
The December retail sales flat-line did not happen in isolation. It followed a period in which several of the structural supports for consumer spending had been weakening simultaneously. Excess savings from the pandemic era — the cushion that had allowed American households to spend beyond their incomes for nearly three years — were largely exhausted by mid-2025 according to Federal Reserve analysis. Credit card delinquencies, while not at crisis levels, had been trending upward since the middle of the year. And consumer confidence had been declining on a trend basis, even as headline economic data remained robust.
The December data suggested those underlying weaknesses had finally surfaced in actual spending behavior. Consumers were not simply being cautious — they were pulling back on discretionary purchases in a way that produced measurably no growth across the retail sector as a whole. The 0.0% print was not concentrated in one category. It was broad-based, which is what makes it particularly informative about the underlying health of consumer demand.
"The December retail sales number is telling us that the consumer, who has been the engine of this expansion, took a meaningful pause at year-end. Whether that pause becomes a sustained slowdown depends on what happens to real incomes, tariff costs, and the labor market over the next two quarters."

The Tariff Pressure That Is Still Building
The December retail sales data reflects a consumer operating in a tariff environment that, by most assessments, has only partially passed through to consumer prices. JPMorgan analysis published this month suggests that businesses absorbed approximately 80% of tariff costs in 2025 by compressing margins rather than raising prices. That dynamic — which allowed the inflation pass-through to remain muted even as tariff rates climbed — is not sustainable.
The same JPMorgan analysis projected that the balance would shift significantly in 2026, with consumers absorbing a much larger share of tariff costs as businesses reach the limit of their margin flexibility. The Tax Foundation has estimated that tariff costs to American households were approximately $1,000 per year in 2025 and are projected to rise to approximately $1,300 per year in 2026 as the pass-through accelerates. A Yale Budget Lab study found that American consumers and businesses are already paying 96% of US tariff costs, with foreign exporters absorbing just 4%.
If the December retail sales stall represents a consumer hitting a ceiling on spending capacity at current price levels — and the flat print provides some evidence for that interpretation — then the additional tariff pass-through projected for 2026 arrives into an environment that may be less resilient than the headline GDP numbers suggest.
What the Data Means for Friday's Releases
The Q4 GDP advance estimate arriving Friday morning will incorporate December data across the full economy, not just the retail sector. But retail sales — which are a proxy for consumer spending, the 70% of GDP that drives the American economic engine — carry significant weight in the GDP calculation. A zero in December creates a mathematical headwind for the Q4 average.
The consensus estimate for Q4 GDP has been around 3%, a healthy number that would validate the soft-landing narrative. But if the December weakness was broader than retail alone — if consumer services spending, which is not captured in retail sales, also softened in the final month of the quarter — the GDP number could surprise to the downside. A print below 2.5% would meaningfully change the economic narrative entering the spring.
The December PCE report, arriving simultaneously with GDP, will tell the inflation side of the story. PCE measures spending on both goods and services, and includes a broader basket of consumption than retail sales. If PCE shows that consumers were spending on services even as goods purchases stalled, the overall picture of consumer demand would be more nuanced. If PCE also shows weakness, the growth concern becomes more pronounced.
The Confidence Gap That Explains Everything
Beneath the aggregate data is a partisan divide in consumer confidence that is unlike anything economists have observed in the modern survey era. The gap between Republican and Democratic consumer sentiment reached approximately 50 percentage points in early 2026 — the widest recorded in the history of the Michigan consumer sentiment survey. Republican respondents were reporting near-record confidence in their financial futures. Democratic respondents were reporting near-recessionary pessimism.
This kind of bifurcated data creates interpretive challenges for economists. The aggregate sentiment numbers look moderate — neither overwhelmingly optimistic nor deeply pessimistic — because they are averaging across two populations that are experiencing the economy in entirely different ways. But the aggregate masks the reality that a very large share of American consumers are operating with the spending psychology of a recession, even if the economic data does not yet fully reflect that psychology in output.
The partisan confidence gap is not just a political curiosity. It has real economic consequences. Consumers who feel economically pessimistic defer large purchases, reduce discretionary spending, and increase precautionary savings. If that behavioral pattern is concentrated among half the population, the aggregate demand signal will show up in data like the December retail sales flat-line — not dramatic enough to trigger a recession alarm, but persistent enough to gradually erode the momentum that has characterized the expansion.
Three Scenarios for What Comes Next
The first scenario is that December was an anomaly — a one-month pause driven by weather, holiday timing effects, and the lingering shadow of the government shutdown rather than a genuine inflection in consumer behavior. Under this scenario, January and February data bounce back, Q4 GDP comes in solidly at 3% or above, and the consumer exhaustion concern fades as a narrative. The market's base case heading into Friday leans in this direction.
The second scenario is that December was the first visible sign of a genuine consumer deceleration driven by the combination of tariff cost pass-through, credit exhaustion, and confidence deterioration. Under this scenario, Q4 GDP surprises to the downside, and the Q1 2026 data shows continuation of the trend. This would strengthen the case for Fed rate cuts and produce a meaningful shift in market positioning.
The third scenario — and the most dangerous for portfolio construction — is the one where GDP comes in strong because of business investment and net exports, while consumer spending is quietly deteriorating beneath the surface. Under this scenario, the headline number masks the underlying consumer stress, the Fed sees no urgency to cut, tariff pass-through continues to accumulate, and the consumer slowdown that appears manageable in December becomes more pronounced in the spring without triggering the data-based response that would arrest it.
The December retail sales number at 0.0% is one data point. Tomorrow it becomes one data point in the context of a comprehensive picture of fourth-quarter economic activity. The weight of that context will determine whether zero was a pause or a warning.
