High interest rates have constrained credit card consumption in the United States. The average annual percentage rate for retail credit cards reached 28.93% in October, up from 26.72% last year, according to Bankrate. Many holiday shoppers could be in for even more financial strain if the high interest rate environment persists. About 52% of Americans incurred credit card debt during holiday shopping last year, and as of mid-August, nearly a third have yet to pay off their balances, according to NerdWallet.
