According to Equifax's May National Consumer Credit Trends Report, existing bank credit card balances as of April 2012 were 28% below their peak.  Balances were $531 billion in April 2012 compared to slightly more than $730 billion in January 2009. Retail card balances have not trended up or down, remaining even with seasonally adjusted pre-recession levels, however the number of retail card accounts fell sharply. Over the 28 months ending December 2010, card accounts fell by 22%. They have since grown by 4.7%, now reaching 173 million accounts. In April 2012, available credit for retail credit cards (the difference between total credit limits and balances) increased approximately $5 billion after bottoming out in Q4 2011, driven primarily by rising credit limits.

"The combination of increased available credit and more timely payments among card borrowers has led to the recent growth in card lending," said Equifax Chief Economist Amy Crews Cutts. "Consumers are starting to respond to increased credit availability both in cards and other tradelines, a signal of both their financial confidence and improving economic conditions. In turn, this increased consumer credit activity bodes well for U.S. economic growth through the second half of 2012."

Other highlights of the data include:

• Aggregated bank card credit limits have held steady for the past six months at $2.4 trillion, roughly 6.6% higher than the low point set in February 2011.
• From April 2010 to April 2012, bank card balance write-off rates declined by more than half (from 13.2% to less than 6%).
• New bank card issuance rose almost 37% in February 2012 relative to the same month a year ago.
• The credit limit on new cards averaged $4784 in February 2012, a 17% increase from February 2011 average of $4,008.
• Utilization (the ratio of balances to credit limits) was slightly more than 22% in April 2012, nearly equaling November 2007 lows.
• As of March 2012, roll rates (the rate at which consumers progress from the "current" stage in payments to 30 days past due) have remained below 1% since February. This marks the first instance in more than five years roll rates have remained at this level for more than two months.  
• Bank credit card charge-off dollar rates (amounts deemed uncollectable by banks) hit 5% in April 2012, nearly 58% lower than the March 2010 peak of nearly 12%.
• Retail card credit limits are stabilizing after falling 15% in early 2010 and another 7% in mid 2011 (currently at $299 billion).
