Paul Krugman says “…there’s no longer any reason to believe that the wizards of Wall Street actually contribute anything positive to society, let alone enough to justify those humongous paychecks.” Bank of America’s credit card practices are a perfect demonstration, right down to the part where they make stuff up.

Let’s look at the latest 10-Q. Massive businesses like BAC (the ticker symbol for Bank of America) report their businesses by segment. After acquiring Merrill Lynch, BAC changed its segment descriptions. The new segments are on page 92. Credit cards have their own segment now. Page 95.

Banks make money on cards from interest on balances and from fee income. The latter category is down from the first quarter of 2008, for non-operational reasons. Interest income, on the other hand, is up from $4.5bn to $5.2bn. The SEC requires management to explain significant changes:

Net interest income grew $680 million, or 15 percent, to $5.2 billion for the three months ended March 31, 2009 compared to the same period in 2008 driven by increased loan spreads due to the beneficial impact of lower short-term interest rates on our funding costs partially offset by a decrease in managed average loans and leases of $4.7 billion, or two percent.

Page 95-6. BAC had higher interest income because its cost of money was a lot lower, which is due directly to the infusions of money from the Treasury and Fed programs. But, BAC doesn’t tell us about its increases in credit card rates to its paying customers. There has been extensive reporting of anecdotal evidence over the last year or so. ABC News gives us an example:

One of those taxpayers, Mindy Busch, graduated from college today. She and her husband, Michael, are now expecting a baby. What they were not expecting were the rate hikes on the credit cards they pay faithfully. Bank of America raised their interest rate from 20 percent to 32 percent.

"It’s just not fair," Busch said. "We pay every month, and this is a bank that is benefitting already from our taxpayer dollars."

Bank of America told ABC News they could not comment on an individual’s account. As far as rates go, the bank said, "Any hikes reflect the current economic conditions. Our costs of providing credit have significantly increased."

Liar, liar, pants on fire. Too bad ABC News didn’t take a look at the 10-Q.
