I haven't been posting much because I've been researching and writing a very long analysis of the credit default swap market, which it seems almost no one understands. I've found really only about five sources that seem to understand what's going on -- three are pretty much nutcases, but also one NY Times Reporter, plus the Attorney General of New York, Andrew Cuomo.
It is a very, very serious, dangerous situation, but not for the reasons most people think. The size of the market, for example, which lots of people are variously mis-estimating, from $45 trillion to $450 trillion to $800 trillion, obviously isn't being accurately portrayed because all those different estimates can't be right; but more to the point, they are probably not relevant.
I'll hopefully post this longish analysis later. Basically, if you can understand "dynamic hedging," you'll be able to understand both why the market seems so large, why the size isn't important, but what the real dangers are.
But in the meantime, here's a child's game that helps explain by analogy what's going on with the size.
Remember the game "hot potato"? You get a bunch of kids in a circle, and the kids pass a potato around. They pass it as fast as possible while music plays, and when the music stops, the kid with the potato loses. It's kind of like musical chairs with a potato.
Imagine a slight variation. Let's say you line up 100 kids. Each kid has about $2.00 in change in his pocket. You start with a baseball card that is worth somewhere between $1 and $2.
You as the zero player "sell" the baseball card to kid number 1 for $1.01 . The kid does not have to pay you right now, but only promises to pay you. That kid 1 now owes you $1.01 .
Each kid in turn sells that card to the next kid adding one penny to the price. Each kid does not pay, but promises to pay. Kid 1 sells the card to kid 2 for $1.02 . Kid 2 sells the card to kid 3 for $1.03 . And so on.
When we get to kid 100, the price is now $2.00 . Each kid owes the kid next to him one dollar and something; but that same kid is owed one dollar and something. In fact, each kid has a net debt of 1 penny.
If you add up the "market" for that baseball card -- the total of all amounts owed on the cards -- it is $150 ! The total debt owed by all the kids in the market is $150! Wow, no kid has that kind of money, right? Oh my God! Holy shit, there are $150 in derivatives but the underlying asset is only worth $2! or maybe only $1 if the market has collapsed! Each kid has only $2, so how can any one kid possibly pay $150?!?!?
But in reality, each kid is only a net debtor of one penny, and a gross debtor of between $1 and $2. The $150 is misleading because it aggregates the value of all the trades (or notional value of all the debts) rather than the value of all the net debts (100 kids owing one penny each or $1) or the value of the underlying asset (between $1 and $2).
Now it is true that if you tried to settle these debts with a bunch of screaming kids, you could create an unsolvable problem which would freeze up the baseball card market -- and the kids are about as disciplined as derivatives traders -- but that's a different problem from the scale of the market.
Now here's some scary data. It seems that Lehman was said to "owe" $400 billion in credit default swaps, and that helped put in in liquidation. But at least one source says that when all the counterparty trades were "netted" against each other Lehman's actual debt was $8 billion. So an $8 billion net debt that Lehman could easily have paid or raised, was magnified 50 times.
On edit: I would ask that you NOT rec this post. I want to work out the rest of the longish piece and get my sources in order before I present it to a larger audience.
