Nothing has changed for the better at J.P. Morgan Chase, as described by Matt Taibbi. It's clearly time to break up the big Wall Street banks.

If you can fight through the jargon, what this basically means is that Chase decided to go into the fiction business and invent a new way to value its crazy-ass derivative bets, using, among other things, a computerized model the company designed itself called "P&L predict" which subjectively calculated the value of the entire fund toward the end of every business day. If this all sounds familiar, it's because it's the same story we've heard over and over again in the financial-scandal era, from Enron to WorldCom to Lehman Brothers - when the going gets tough, and huge companies start to lose money, they change their own accounting methodologies to hide their screw-ups, passing the buck over and over again until the mess explodes into the public's lap. The difference is that Chase is a much bigger and more dangerous company to be engaging in this kind of behavior. An even scarier section of the report regards the reaction of the Office of the Comptroller of the Currency, or OCC, the primary government regulator of Chase. The report exposes two huge problems here. One, Chase consistently hid crucial information from the OCC, including the sort of massive increases in risk the OCC was created precisely to monitor. Two, even when the bank didn't hide stuff, the OCC was either too slow or too disinterested to take notice of potential problems.
