The Growing Divides in the US Economy: Impacts and Implications for the Banking Sector
In today’s economic discourse, the term “K-shaped” economy is gaining traction. This term vividly illustrates the stark reality of economic divergence, with the top segment experiencing growth while the majority grapple with financial decline. To paraphrase Gene Ludwig, a significant majority of Americans are now living lives of permanent financial stress, and debt delinquency is on the rise. For bankers, that’s a recipe for problems with profitability, and perhaps with safety and soundness.
Unveiling the K-shaped Economy
For many years, I have been studying this economic phenomenon at the Ludwig Institute for Shared Economic Prosperity. Through our analysis of long-term trends, we have come to realize that this structural divergence is far more pronounced and deeply embedded than many realize. This research reveals a more pronounced K-shaped economy in which economic gains are increasingly concentrated at the top while financial stress intensifies for a majority of households.
The Impact on Households
The real concern for bankers is not merely the existence of the “K” but the wide gulf between those on the upward and downward slopes. This divide has left roughly 60% of Americans on the downward side, struggling with financial stress. Over the past quarter-century, the cost of essential goods and services such as housing, healthcare, childcare, transportation, and food has skyrocketed, outpacing wage growth and the Consumer Price Index. As a result, many households rely on credit, balance-sheet strain, or government assistance to maintain a minimal quality of life. This reliance on credit is increasingly visible on bank balance sheets with total U.S. credit card debt reaching roughly $1.23 trillion as of the third quarter of 2025.
Consumer Spending and the Banking Sector
Consumer spending has also become top-heavy. Today, more than half of consumer spending comes from the upper 20% of households, leaving the bottom 60% contributing a disproportionately smaller share. This economic bifurcation presents both opportunities and risks for banks. Banks are benefiting from the increased reliance on credit by many American households. However, the same dynamics that fuel loan demand also increase the share of borrowers with thinner margins for error. This pressure is beginning to be evident in credit performance.
Banking Industry: Opportunities and Challenges
As the K-shaped economy becomes more vertical, it increases systemic risk and poses more stress for banks. Over time, these dynamics are likely to reshape the banking industry. As income and spending become more concentrated, assets and earnings may increasingly accrue to the largest institutions, while smaller banks face pressure from credit stress, funding costs, and scale disadvantages. This pattern risks accelerating consolidation, leaving fewer institutions holding a larger share of the system’s assets.
What Can Banks Do?
Banks and other financial service providers have a role to play in improving the economic picture for those on the downward slope of the K. Expanded financial education, proactive money-management tools, and early intervention strategies can certainly help. However, these efforts, while important, are not sufficient to reshape the broader economic trajectory. Changing the shape of the K requires participation from other players and policy action beyond the banking sector. The government must leverage business tools, tax and regulatory policy, to stimulate U.S. business and reduce taxes on lower-income Americans, thereby expanding the availability of living-wage jobs.
Conclusion
Ultimately, a resilient system cannot rest on an economy that leaves a majority of households under sustained financial strain. Over time, that imbalance creates systemic pressure, challenging even well-capitalized institutions. For banks, long-term performance is inseparable from a more balanced economic trajectory. Supporting policy reforms and product innovations that broaden opportunity is therefore not ancillary to business but central to maintaining sound credit performance, stable growth, and the long-term health of the industry.
