The Federal Reserve Bank of New York has released research documenting what many economists suspected: the U.S. economy is increasingly dependent on spending from its wealthiest households, creating a potential vulnerability if financial markets stumble.
The data presents a stark picture of divergence across income groups since early 2023. High-income households, those earning more than $125,000 annually, have grown their real retail spending by about 7.6% through March 2026. Middle-income households managed roughly 3% growth. Low-income households, earning under $40,000, saw barely more than 1%.
This K-shaped split represents a fundamental shift from the pre-pandemic economy, when lower-income households actually outpaced the wealthy in spending growth. The reversal began in 2023 as federal relief programs for struggling Americans expired, and the gap has only widened since.
What makes the trend especially worrying is the underlying driver. Wage growth alone cannot explain the divergence, New York Fed researchers found. Instead, the real engine behind wealthy households' spending is their surging financial assets. The real net worth of the top 1% of earners has climbed more than 25% since 2023, fueled largely by stock market and investment gains. By contrast, the middle 40% of households has gained less than 10%.
Meanwhile, lower-income households have been hammered by inflation that continues to run above the national average, leaving them vulnerable to any additional economic shock.
"Reliance on a single segment of the economy has important implications for spending growth and its fragility, as well as for economic vulnerability and policy," New York Fed researchers wrote in a Friday blog post. They raised a critical concern: the economy's heavy dependence on wealth gains from financial assets means consumer spending could collapse rapidly if markets decline.
Complicating the picture, real spending has turned negative across all income groups in recent months, even as the gap between rich and poor persists. This suggests the entire consumer base is weakening, though the wealthy retain far more cushion to weather a downturn.
Not all economists accept the K-shaped narrative wholesale. Pantheon Macroeconomics has argued that the wealthiest households have accounted for a roughly stable 40% share of total consumer spending for the past 25 years. If true, this would suggest the current split reflects a long-standing feature of American consumption rather than a new vulnerability.
Yet the New York Fed's emphasis on financial assets as the primary driver of the wealth gap points to a genuine risk: the fragility of an economy increasingly reliant on stock market performance to fuel consumer demand. When bubbles burst, spending typically follows.
Author James Rodriguez: "A K-shaped recovery that depends entirely on Wall Street gains is a bet the economy can't afford to lose."
