Mike, I found the credit writedowns site very interesting and bookmarked it. Did you read this:
Reported estimates of the size of the credit default swap market have so far been based on surveys. These surveys tend to overstate the size of the market due to each party to a trade separately reporting its own side. Thus, when two parties to a single $10 million dollar trade each report their “side” of the trade, the amount reported is $20 million, which overstates the actual size by a factor of two since both reports relate to a single $10 million contract. When examining the outstanding amount of actual contracts registered in the Warehouse (not separately reported “sides”) as of October 9, 2008, credit default swap contracts registered in the Warehouse totaled approximately $34.8 trillion (in US Dollar equivalents). This is down significantly from the approximately $44 trillion that were registered in the Warehouse at the end of April this year.
I wonder how much the $516 trillion # in your chart may eventually come down.
