It’s the second straight quarter that credit card delinquency rates have remained at about 13%. Credit card delinquency reached its highest level in early 2010 at nearly 14%. Credit card delinquency rates are similar to levels seen in early 2011. Despite having the highest rate of credit card balances with a missed payment of 90 or more days, 18- to 29-year-olds make up the lowest total of credit card debt at $80.8 billion. The Federal Reserve Bank of New York revised its March credit card balance estimate from $1.25 trillion to $1.24 trillion.
