It’s possible the difference will disappear with future revisions, but for now the new report showed credit unions leading banks by a wide margin for December and January.

The report showed credit unions held $86.5 billion in credit card debt, up 5.2% from a year earlier. The gain was 0.9% from December to January, compared with the 10-year average December-to-January drop of 1.0%.

Banks held $1.2 trillion in credit card debt, down 0.4% from a year earlier and down 2.1% from December, slightly milder than their 10-year average December-to-January drop of 2.4%.

Credit unions’ share was 6.7% in January, up from 6.4% a year earlier and 6.5% in December. Banks’ share was 90.4% in January, down from 90.6% both a year earlier and a month earlier.

The Fed revised bank credit card balances for October through December, but the biggest change was for December. What was reported a month ago as a 5.2% balance gain for banks in December from a year earlier is now a 0.2% drop.

Bank gains also fell from 3.9% to a revised 3.2% for November, and from 6.4% to a revised 6.1% for October.

The G-19 also showed credit unions held $564.1 billion in auto loans, personal loans and other non-revolving consumer loans in January, down 2.5% from a year earlier. It was also down 0.1% from December, compared with their 10-year average December-to-January gain of 1.1%.

Banks held $822.7 billion in non-revolving consumer loans in January, down 9.1% from a year earlier. It was up 0.6% from December, compared with the 10-year average gain of 0.4%.
