The latest quarterly earnings from America's four largest banks convey an unexpected signal: despite geopolitical conflicts driving up oil prices and causing sharp stock market swings, American consumers' financial conditions remain robust.

First-quarter results released this week by JPMorgan Chase, Citigroup, Bank of America, and Wells Fargo indicate that consumer credit quality and spending patterns continue to trend healthily.

Jeremy Barnum, Chief Financial Officer of JPMorgan Chase, stated during an analyst conference call that the U.S. economy has demonstrated "surprisingly resilient" performance, as have consumers. "The story remains unchanged: a highly resilient consumer who continues to perform well despite higher oil prices."

Jefferies analyst John Hecht views the earnings reports from the Big Four banks as a positive indicator for payment companies, including American Express, which is scheduled to release its results later this month.

Bank Executives Unanimously Cite Consumer "Resilience"

"Resilience" has become the recurring keyword used by bank executives this week when describing customer conditions.

Barnum noted on the conference call that JPMorgan Chase examined consumer conditions across multiple dimensions, including early delinquency roll rates, delinquency rates, cash buffers, overall spending, discretionary spending, and non-discretionary spending. "All metrics align with prior trends, indicating a healthy fundamental picture," he said.

He also flagged potential risks: if the labor market weakens and the conflict in the Middle East persists, cascading effects could follow. However, for now, there are no clear signs of significant deterioration in consumer conditions.

Credit Quality Improves, Spending Structure Remains Stable

In terms of specific data, spending patterns and balance growth across the four banks' credit card portfolios maintain a "constructive" trajectory.

John Hecht of Jefferies pointed out that compared to a year ago, delinquency rates and net charge-offs at each bank have improved—two key indicators for assessing credit quality. In his Wednesday research report, Hecht wrote that banking results "support our view of stable borrower conditions, even amid ongoing macroeconomic uncertainty, with spending trends partially buoyed by higher tax refunds."

The first quarter was not without turbulence. The U.S.-Iran conflict pushed gasoline prices higher, reigniting inflation concerns, while significant stock market volatility dampened borrower confidence. Yet, these external shocks have not left obvious marks on consumer data.
