Credit card balances have typically fallen month-to-month from January through March, but start to show gains in April, based on 10-year averages of Fed data for all lenders from 2010 through 2019. The average March-to-April gain was 0.40% over those years.

The good news is that among all lenders, credit card balances rose from March to April, albeit by a bare 0.07%.

The bad news for credit unions was that the March-to-April gain was almost entirely at banks, where balances showed a 0.13% gain, while credit union balances fell 0.92%.

As a result, credit unions' share of the market fell to 6.3%, down from 6.4% in both March 2021 and April 2020.

The road was also bumpy for credit unions in auto lending in April.

CUNA's Credit Union Monthly Estimates released June 4 showed new car loans stood at $138.5 billion on April 30, down 5.6% from April 2020 and down 0.3% from March 2021. On the bright side, it was the smallest in the string of month-to-month drops. The previous four declines ranged from 0.6% to 2.4%.

Used car loans stood at $245.7 billion on April 30, up 6.1% from April 2020 and up 0.6% from March 2021.

Overall auto loans were $384.3 billion in April, up 1.5% from a year earlier and 0.2% from the previous month.

CUNA's report also showed credit unions had 128.1 million members in April, 3.3% more than a year earlier.

• Loans per member grew 1.7% to $9,404.
