The latest quarterly earnings from America's four largest banks convey a surprising signal: despite geopolitical conflicts driving up oil prices and significant stock market volatility, the financial health of U.S. consumers remains robust. Results for the first quarter, released successively this week by JPMorgan Chase, Citigroup, Bank of America, and Wells Fargo, indicate that consumer credit quality and spending continue to reflect a healthy trend.

JPMorgan's Chief Financial Officer, Jeremy Barnum, stated during an analyst conference call that the U.S. economy has shown "surprising resilience," and the same holds true for consumers. "The story remains the same: a very resilient consumer, performing well even in the face of higher oil prices," he said. Jefferies analyst John Hecht views the results from the big four banks as a positive indicator for payment companies, including American Express, which is set to report earnings later this month.

Bank executives were unanimous in their assessment, repeatedly using the term "resilient" to describe customer conditions. Barnum explained that JPMorgan examined consumer health from multiple angles, including early-stage delinquency roll rates, delinquency rates, cash buffers, overall spending, and both discretionary and non-discretionary expenditures. "All metrics remain consistent with prior trends, with healthy fundamentals," he noted. He did caution, however, that a weakening labor market combined with ongoing Middle East conflicts could have ripple effects. For now, though, there are no clear signs of deterioration in consumer conditions.

Looking at specific data, spending patterns and balance growth in the credit card businesses of the four major banks have maintained a "constructive" trajectory. Jefferies analyst John Hecht pointed out that delinquency rates and net charge-off rates have improved compared to a year ago—both key indicators of credit quality. In a research report released on Wednesday, Hecht wrote that the banking results "support our view of stable borrower conditions, despite lingering macroeconomic uncertainties, with spending trends also partly boosted by higher tax refunds."

The first quarter was not without turbulence. Conflict in the Middle East pushed gasoline prices higher, reigniting inflation concerns, and sharp stock market swings also weighed on borrower confidence. However, these external shocks have not yet left a clear mark on consumer spending data.
