First off, Chaz knows a guy who saw the documents in question. Unfortunately, this character had no idea what anything in there meant.
...one source who claims to have read some of the documents held by WikiLeaks confirms that they do in fact involve Bank of America. Adding to the mystery, however, this source says that they found it difficult to determine just what they mean. Given that Wall Street's straightforward business—buying and selling, borrowing and lending—now requires a math Ph.D. to understand, this shouldn't be too shocking.
And so it falls to Gaspo, naturally, to come up with something.
Here's the problem for Bank of America: Its mortgage origination business, like the rest of that industry, probably witnessed rampant fraud during the bubble years. Banks made loans to borrowers without proper documentation of employment and other pertinent information. Since Countrywide focused on the low end of the market, the so-called subprime market where people who borrowed money have lousy credit histories, it's only logical to assume many of those loans were at least risky, if not made fraudulently.
This is just an educated guess: I have no evidence whether Countrywide's lending practices were so lax (and some would say corrupt) that loans were made to people who either lied about their finances or had mortgage brokers lie about that information. But it's the same educated guess made by many sophisticated traders last week when the WikiLeaks issue emerged, and BofA's share began to tank.
