Credit union card issuers, like card issuers overall, have enjoyed a relatively strong drop in credit card delinquency over the past few months as more consumers cut back on their spending and focus on paying off debt. But there are signs that trend may be reaching its end.

A website that specializes in tracking credit card trends and recommending consumer-friendly credit cards says the months long decline in credit card delinquency rates overall may have run its course. Card delinquency has slid sharply from its previous high in 2009.

Bill Hardekopf, CEO of LowCards.com, said an analysis of data from major card issuers shows that five of the top six saw delinquency rise by a small amount in September.

LowCards looked at the rates of cardholders who were at least 30 days late with their September payments and noted that “it could be a signal that consumers are again struggling to pay down credit card debt and are a higher risk for default in the future.”

The five major issuers that LowCards found had higher delinquency in September were American Express, Capital One, Bank of America, Chase and Discover. The one major card issuer that saw delinquency drop was Citibank.

American Express saw its delinquency rise to 1.5% from 1.4% in August. Capital One saw its rate increase to 3.65% from 3.43% in August. Bank of America saw its delinquency rise to 3.99% from 3.96%. Chase' delinquency rose to 2.53% from 2.48% and Discover's rate moved to 2.5% from 2.49%. Citibank's card delinquency declined to 1.7%, down from 1.81% in August.

All card issuers reported their charge rates continued to decline, reflecting the previous delinquency drops. Credit unions have generally had card delinquency sharply lower than that of major issuers, but credit union card delinquency has often increased and decreased along with the overall industry.
