K-Shaped Consumer Spending

K-shaped consumer spending is the source’s 2026 watchpoint for aggregate consumption that may be disproportionately carried by high-income households. In Indicators of 2025 and What to Watch in 2026, Cooper Katz-McKim contrasts resilient hard spending data with weak [[ConsumerSentimentIndicator|consumer sentiment]], then cites RBC for the claim that the top 10% of consumers account for a near majority of spending.

The concept matters because aggregate demand can look healthy while stress builds below the top income slice. The episode points to reduced confidence, record-high auto loan delinquencies, and record-high credit card debt outside the highest-income group, while higher-income consumers benefit from rising home values and a strong stock market.

Key Claims

• Consumer spending can remain strong even when most households feel worse if high-income households keep spending.
• Stock-market strength can support spending through richer households, but it also makes demand more vulnerable to a market correction.
• Tax cuts that mainly benefit upper-income households can reinforce the top-heavy spending pattern in the source’s account.
• The concept links CAPE Ratio Valuation Signal to the real economy through household wealth exposure, not only through market valuation.
