Anecdotal evidence suggests even affluent consumers are pulling back on spending, despite a strong stock market. This may be driven by concerns over the weakening job market, as even well-to-do parents worry about their adult children's employment prospects, creating caution across the family unit.

The economic theory that rising asset values boost spending is flawed. It ignores 'mental accounting'—people treat different types of wealth differently. A rise in home value leads to almost zero increased spending, while a cash windfall from a stock sale or lottery win is spent freely. The source of wealth dictates its use.

Consumer spending resilience is not broad-based. It's largely driven by the top 10% of income earners (making over $275k), who now account for almost 50% of total spending. This is the only cohort whose spending has outpaced inflation since the pandemic, making the wider economy highly sensitive to their behavior.

The resilience of consumer spending, despite weak employment growth, is driven by affluent consumers liquidating assets or drawing down cash. This balance sheet-driven consumption explains why traditional income-based models (like savings rates) are failing to predict a slowdown.

While high-income spending remains stable, the next wave of consumption growth will stem from a recovery in the middle-income segment. This rebound will be driven by stabilizing factors like reduced policy uncertainty and neutral monetary policy, not a major labor market acceleration.

A significant gap exists between weak real income growth (~1%) and stronger real consumption (~2%). This suggests consumers are funding their spending through the wealth effect of a rising stock market, creating a fragile dependency on equity performance.

Despite a still-growing labor market, real wage growth has slowed to "stall speed." This lagged effect on middle and lower-income households is the primary driver for the projected 2-percentage-point drop in real consumption growth for Q4 and Q1.

The link between asset prices and spending, which weakened after 2008, has restrengthened to levels last seen in the 1990s tech bubble. Surging stock prices are directly fueling consumption, explaining why spending remains robust despite near-zero real income growth. This makes the economy highly vulnerable to a market correction.

Headline income figures are being distorted by one-off government payments. The critical underlying metric—real, after-tax disposable income—has shown zero year-over-year growth for three consecutive months. This is the primary fuel for spending, and its stagnation is a major red flag for the U.S. consumer.
