Can the rich continue to prop up US consumer spending?

U.S. consumer spending's surprising resilience, a key factor in avoiding recession, is increasingly reliant on high-income earners, with the wealthiest 10% now accounting for a record 50% of total consumption. While this cohort maintains credit card headroom and benefits from robust labor income growth, supporting the current economic trajectory, significant risks remain, including the potential for a Wall Street correction to negatively impact their substantial equity holdings, a flatlining of inflation-adjusted spending in H1, and the prospect of consumers absorbing a larger share of tariff costs, creating a nuanced outlook for future economic growth.

Analysis

The US economy's continued expansion is disproportionately reliant on the spending of high-income households, creating a concentrated and precarious source of growth. Analysis from Moody's Analytics indicates a structural shift, with the wealthiest 10% of Americans now responsible for a record 50% of all consumer spending, a significant increase from 36% three decades prior. This cohort's capacity to spend is supported by strong balance sheets, as noted in a Boston Fed paper, which found their credit card debt remains below pre-pandemic levels, suggesting available borrowing capacity. Furthermore, robust labor market dynamics, highlighted by a Bank of America calculation of a 5.5% annualized increase in aggregate labor income, are fueling real wage growth and supporting consumption. However, this foundation faces significant risks. The extreme concentration of wealth means a stock market correction could severely impact spending via the negative wealth effect, as the top 10% own approximately 90% of equity assets. This risk is compounded by other headwinds, including a flatlining of inflation-adjusted personal consumption expenditures in the first half of the year and the potential for consumers to absorb a greater share of tariff costs, which Goldman Sachs estimates could rise from 22% to 67%, directly threatening purchasing power.

Key Decisions for Investors

• Given that the top 10% of earners now drive half of all consumption, investors should closely monitor luxury goods sales and high-end consumer sentiment as key leading indicators for the broader economy's health.
• The heavy reliance of this consumer cohort's wealth on financial markets means that consumer discretionary sector performance is now highly sensitive to equity market volatility; consider hedging strategies for this sector during periods of market instability.
• Monitor upcoming data on tariff cost absorption by consumers and real wage growth, as any material erosion of purchasing power for top earners could rapidly undermine the current economic resilience and challenge the prevailing 'soft landing' narrative.
• The cited strength in labor income underpins the case for a 'higher for longer' interest rate environment, suggesting investors should remain cautious about positioning for imminent Federal Reserve rate cuts.
