The percentage of Americans falling behind on credit card bills stabilized in January, according to data from the six major lenders, signaling that U.S. consumer credit woes may be leveling off.

Shares of the credit card companies all jumped to at least one-week highs, as analysts said the loan delinquency rates were surprisingly benign, suggesting the worst for U.S. consumers may have already passed.

Bank of America Corp and American Express Co reported drops in both credit card delinquency rates and in charge-offs. Bank of America stock, which ended 4.9 percent higher at $15.16, was the biggest percentage gainer in the Dow Jones Industrial average, while American Express gained 3.1 percent to $39.62, its highest level in more than three weeks.

Capital One Financial Corp, Discover Financial Services, JPMorgan Chase & Co and Citigroup Inc also posted delinquency rates for January little changed from December. The rates signal how likely credit card issuers are to have to write off bad loans in the future.

What is very positive is that the delinquency trends ... were at the low end or better than the range that we were expecting, said Richard Shane, an analyst at Jefferies & Co.

The data is suggesting that not only will we see a seasonal recovery (in March or April), but there is a cyclical recovery that's beginning that will start to impact data in the second half of 2010.

Charge-offs -- or loans the company does not expect to be repaid -- were mixed in January.

The January data, while not uniform, follows a December that also showed signs fewer Americans were falling behind in payments. It continues a reversal from November, when most companies reported a rise in charge-offs, which reflect stress on consumers.

The delinquency rate at Bank of America, the biggest U.S. bank, was 7.35 percent in January, down 0.09 percent from 7.44 percent in December. Its charge-offs dipped 0.28 percent in the same period.

While Bank of America had the highest numbers in the group, American Express, the largest U.S. credit card company by purchase volume, posted the lowest. American Express said its delinquency and charge-off rates each fell by about 0.1 percent in January, compared with December.

Capital One, JPMorgan Chase, and Citigroup wrote off a higher percentage of loans, while American Express, Bank of America and Discover wrote off a lower percentage.

Companies lifted credit card rates last summer, which set off an expected rise in charge-offs last month, Shane noted.

You're going to see loss rates rise for another month or two, it's a function of seasonality, but also a function of that spike in delinquencies that we saw late summer and early fall, the analyst said.

Capital One shares climbed 4.5 percent to close at $36.74; JPMorgan shares added 2.9 percent to $40.07; Citigroup was up 4.1 percent at $3.31; and Discover was up 4 percent at $13.55.

For Capital One, borrowers with about 5.8 percent of U.S. credit card loans were more than 30 days behind on their bills in January, on an annualized basis. That is essentially unchanged from December's 5.78 percent. Capital One's charge-off rate rose 0.3 percent month-over-month.

JPMorgan Chase wrote off 10.91 percent of its loans, on an annualized basis, a big increase from December's 7.11 percent. The company said in January that write-offs could approach 11 percent, due to a payment holiday it allowed customers in May, which lowered defaults in late 2009 and are boosting them now.

Discover reported a 0.06 percent rise in its delinquency rate in January, and a very slim drop in the charge-off rate. Citigroup, the last company to report on Tuesday, said its delinquency rate rose 0.13 percent -- the steepest rise of the six companies -- and its charge-off rate rose 0.24 percent.

Credit card charge-offs and delinquencies usually track U.S. unemployment, which fell to a five-month low of 9.7 percent in January. That surprised economists and hinted at a labor market recovery despite the loss of 20,000 jobs in the month.
