Credit unions continued to build balances with credit cards and consumer term loans even amid signs auto loan balances among all lenders have stalled since last September, according to a Fed report.

The Fed's Consumer Credit Report released Tuesday showed credit unions held $80.3 billion in credit card debt, up 7.6% from a year earlier. The balance fell 0.4% from February, compared with the 10-year average February-to-March drop of 0.1%. Balances typically fall in the first three months of the year as households pay down balances from holiday spending, often with the help of tax refunds.
