U.S., Cuomo Open Credit Default Swap Investigation:

The U.S. government and New York Attorney General Andrew Cuomo opened a joint investigation into the $34.8 trillion credit-default swap market, the top federal prosecutor in New York said

Might be a scapegoat witch hunt though for they are targeting short sellers.

New York Times:

Mr. Cuomo and Mr. Garcia are investigating whether investors drove up the price of swaps in transactions that were reported to data providers but never actually completed, according to people briefed on the investigation. If so, that would have helped anybody who sold short financial shares. In a short-sale, investors sell stocks they do not own in the hopes of buying them back later at a lower price.

To identify whether there was any manipulation, Mr. Cuomo’s office has issued subpoenas seeking data from various parts of the industry, including stock exchanges, investment firms and three companies involved in processing trades in swaps and stocks, according to people briefed on the inquiry.

Those firms are: the Depository Trust Clearing Corporation, which serves as the clearing agent for most financial transactions including swaps and stocks; Markit, which provides swaps data to Wall Street banks and investors; and Bloomberg, the financial data company whose electronic system is used by traders to track markets and communicate with one another

So, if this will lead to more regulation and do something structurally about this massive unregulated market....initial reports don't seem to imply that.
