Slower spending by U.S. cardholders continued in 4Q, according to Citigroup. Citi says U.S. credit card spend volume was up 2% year-on-year, the same growth rate as in the previous quarter. That is a slowdown from in late 2022 and early 2023, when credit card volumes grew 7% from a year earlier, according to Citi results. Weaker spending growth among cardholders is a sign of slumping spending by consumers amid higher interest rates and dwindling pandemic-era savings.
