With debts among other lenders falling faster, credit unions' share of the nation's credit card debt rose slightly to 5.8% in February 2018, up from 5.77% in January 2018 and 5.6% in February 2017.

The other component of the G-19 report is non-revolving consumer debt, which credit unions have been gaining at twice the rate of other lenders.

For credit unions, more than 90% of non-revolving consumer debt comes from car loans. For the national total, student loans account for more than half and car loans about 40% of the debt. The rest comes from a medley of loans for recreational vehicles, boats, computers and appliances.

Credit unions held $372.2 billion in non-revolving debt on Feb. 28, up 11% from a year earlier. Total non-revolving debt was $2.8 trillion in February, up 5% from a year earlier.

That gave credit unions a 13.1% share of non-revolving loans in February, up from 12.4% a year earlier. Their share of all consumer credit was 11.2% in February, up from 10.6% a year ago.

One of reasons for the gains is the increasing ability of members to get a card through their own credit union. About 92% of U.S. credit union members belonged to a credit union that issued credit cards as of December 2017. The NCUA data shows:

• There were 102.8 million members of the 3,430 credit unions that offered credit cards at least since December 2016. Those credit card debts rose 9.5% to $57.8 billion, and represented 6.5% of total loans.
• Another 1.3 million members belonged to one of the 47 credit unions that began issuing cards last year, adding $222.1 million in credit card debt, representing 2.1% of their total loans.
• About 357,000 members belonged to one of the 16 credit unions that stopped issuing cards in 2017, eliminating $25.2 million in credit card debt.
• About 8.3 million members belonged to one of the 2,196 credit unions that have not offered cards—at least in the past year.
