Capital One Financial Corp, one of the largest issuers of MasterCard and Visa credit cards, said on Tuesday that credit card defaults rose in January in the United States as job losses accelerated and unemployment soared to a 16-year peak.

In a regulatory filing, the company said the annual net charge-off rate -- a measure of credit default -- for U.S. credit cards rose to 7.82 percent in January from 7.71 percent in December, while the rate for loans at least 30 days delinquent increased to 5.02 percent from 4.78 percent.

In auto loans, Capital One's charge-off rate rose to 6.09 percent in January from 5.93 percent in December, but the delinquency rate went down to 9.18 percent from 9.91 percent.

In international operations, the charge-off rate fell to 6.1 percent in January from 6.2 percent in December, while the delinquency rate rose to 5.81 percent from 5.51 percent. (Reporting by Juan Lagorio, editing by Steve Orlofsky)
