At credit unions, revolving debt from credit cards and non-revolving loan balances increased from May to June at higher rates than the one-month increases a year earlier.

Credit unions held $58.6 billion in credit card debt on June 30, up 9.8% from a year earlier—and rising twice as fast as other lenders. Credit unions' gain from May to June this year was 0.5%, up from a 0.4% gain a year earlier.

All lenders held $2.9 trillion in non-revolving consumer loans in June, up 4.7% from a year earlier. This included $1.5 trillion in student loans, up 5.8% from a year earlier, and $1.1 trillion in car loans, up 3.6%.

Credit unions held $383.3 billion in non-revolving consumer loans in June, up 9.2% from a year earlier. The increase from May to June this year was 1.9%, up from a 0.7% gain a year earlier.

Total U.S. motor vehicle loans grew 1.6% from March to June, up from a 1.2% gain a year earlier and countering a trend of decelerating growth from the previous five quarters. However the March-to-June growth was still significantly slower than second quarter growth from 2012 to 2016 when it ranged from 2.4% to 2.9%.

Car loans made up only 39% of non-revolving debt among all lenders in June, but it makes up about 94% of credit union non-revolving debt based on total vehicle loans reported by CUNa Mutual Group.

That data places vehicle loans at credit unions at about $361 million as of June 30, or 31.9% of U.S. motor vehicle loans, up from 31.1% in March and 29.7% in June 2017.
