Consumers were starting to deplete savings, the banks said, and Citibank and Wells Fargo noted that losses on credit cards and other debts were starting to rise.
Wells Fargo said it was seeing charge-offs, or loans written off, increasing in its credit card portfolio.
"Currently, U.S. consumers and businesses generally remain healthy, although consumers are spending down their excess cash buffers," said JPMorgan CEO Jamie Dimon.
JPMorgan, Citigroup and Wells Fargo, the first, third and fourth biggest U.S. lenders, respectively, also increased their outlook for NII.
Shares of JPMorgan and Wells Fargo rose between 1% and 3%.
