The U.S. economy is currently facing heightened vulnerability to a potential stock market correction, according to KPMG’s chief economist, Diane Swonk. High earners, who have significantly benefited from the recent surge in artificial intelligence (AI) investments, have been a crucial pillar of the economy, empowering the market to reach unprecedented heights. This growth has contributed to an enhanced “wealth effect,” where increased asset valuations bolster consumer confidence and spending, particularly among the wealthiest.
Swonk emphasized that this economic scenario has intensified the K-shaped recovery trend, where the wealthiest segment of the population, whose assets are closely tied to the stock market, continues to thrive. “We have built up a mountain of wealth that is highly concentrated,” she remarked. A pressing question arises, however: Will this pattern remain intact if there is a market correction, or is there sufficient financial cushion to mitigate the damages? This uncertainty is a source of concern for her.
Research from Moody’s Analytics underscores the significant economic influence exerted by the wealthiest Americans. Mark Zandi, Moody’s chief economist, noted that the top 20% of income earners—those with annual incomes exceeding $175,000—are responsible for nearly 60% of consumer spending. In contrast, spending among the bottom 80% has failed to keep pace with inflation, further intensifying the K-shaped economic divide.
Both Zandi and Swonk have pointed out the disconnect between disheartening consumer sentiment and the robust economic indicators. This disparity suggests that while aggregate economic metrics may appear strong, the reality experienced by many Americans feels quite different. “That has left us with an economy that looks better in the aggregate than it feels to most Americans,” Swonk observed. This sentiment renders the economy increasingly susceptible to downturns in the market.
The wealthiest consumers continue to drive economic growth, with their willingness to spend remaining strong, even amid inflationary pressures. Their financial well-being, bolstered by the bullish stock market, has provided them with greater confidence to spend. However, Swonk raises an important question about the sustainability of this spending behavior: “The unknown is whether those same affluent households will continue to spend as freely if financial markets correct.” This uncertainty looms over the economic landscape, presenting potential ramifications for future growth.
