The Federal Reserve Bank of New York has confirmed that the U.S. economy is operating in a K-shaped pattern, with spending growth heavily concentrated among top earners. The research, published Friday, underscores a risk lurking beneath the surface of an economy already grappling with war-driven energy prices and AI uncertainty. Low-income households, the study finds, are being squeezed by inflation that continues to run above the national average.
The K-shaped dynamic is not a new phenomenon, but the New York Fed's analysis gives it fresh empirical weight. The divergence is largely explained by wealth gains from financial assets, which have disproportionately benefited upper-income brackets. This reliance on a single spending cohort raises concerns about overall economic vulnerability, particularly if the market turns.
Since January 2023, real retail spending growth has varied significantly by income level, according to the data. While high earners have maintained robust consumption, lower-income groups have seen their purchasing power eroded. The research indicates that persistent inflation has left these households with little buffer against additional shocks, deepening the economic divide.
The authors warn that the concentration of spending creates fragility. A sharp pullback by high-income consumers, potentially triggered by a market downturn, could have outsized effects on aggregate demand. The findings also carry implications for policy, suggesting that economic resilience may depend on broadening the base of spending power. "Reliance on a single segment of the economy has important implications for spending growth and its fragility," the New York Fed researchers wrote in a blog post accompanying the study. The research adds to a growing body of evidence that the post-pandemic recovery has been unevenly distributed.
