That’s  the secret of the JP Morgan  lawsuit with the Korean banks. It was  Korean Central Bank money that  these guys pissed away. You had this  incredible device—a Malaysian  corporation formed to write instruments  that would pay off according to  the relative values of the Thai baht  and Japanese yen, and designed  solely for the purpose of selling these  instruments to the Korean banks  because the Korean Central Bank wanted  to increase the return on its  reserve. 
Once  you start to get into this sort  of nonsense, serious problems can  occur for everybody, because you are  dealing in a world of thoroughly  artificial instruments that have  nothing to do with real production,  real consumption, real trade or real  anything. They are simply counters  in a game. But when the players have  to pay off, they have to pay  off in real resources, and that sort of  thing is extremely dangerous  over time.
In October 1997, when the  Brazilian real  came under dramatic attack, nobody could figure out why.  It turned out  that in September ’97, between 20 percent and 25 percent  of all the  Brazilian Brady bonds were held by South Korean banks. The  Brazilian  Brady bonds had a large, liquid market because people were  making a lot  of money trading them and trading derivatives off of them.  So when the  South Korean banks got in trouble, the easiest thing for  them to do was  to sell Bradys. The bonds took a hit and the real took a  hit. And that’s  crazy.
It’s one thing to  talk about a  spillover effect with countries that are closely related  to each other.  It’s another thing to talk about contagion. There have  been artificial  links created between currencies because of the  statistical correlation  in their path behavior. That has nothing to do  with anything.  Correlations and causes can get mixed up anytime, but  the notion that  you put hard money on correlations where there is  no—and can be  no—causation other than the correlation itself is bad  news.
What’s really happening is that  the guys  selling the hedging instruments are writing a form of  insurance. It’s  catastrophe insurance, but they don’t know it’s  catastrophe insurance,  so they have no way to price it that gives them  accurate premiums for  the risks. Nobody knows. The question is whether  there shouldn’t be some  regulator making sure that when the insurance  doesn’t pay off,  important players don’t go absolutely insane and bust.  That’s got to be  addressed.
Banks are supposed to do  information-intensive lending. The notion that the ratings agencies know  what the risks are on loans better than the banks do—well, that’s  really remarkable. It means that everybody has adjusted to a world in  which banks are not going to hold loans in their portfolios. They are  going to sell them off. And the ratings are important for the purpose of  selling off the loans.
We’re moving from a world that was  dominated by specific information in banks to a world dominated by much  less profound but much more widespread information in markets. The clash  between these two systems of valuing instruments is what makes for the  instability that we can see all around us and that will increase.
There’s obviously a real value in credit  derivatives because they allow the farm-belt bank and the rust-belt bank  to swap exposures. By diversifying, both of them have less risk. The  reduction of their returns is minor because the cost of these contracts  is minor.
In some cases, you’re not swapping  portfolios of loans. You’re gambling on the relative return of a  risk-free instrument against an equity portfolio, a portfolio with junk  bonds, a portfolio of foreign currencies or whatever, in which there is a  larger risk.Nobody knows what the hell is  going on in these private deals, and nobody knows the volume of what is  out there, including regulators. So nobody can have an informed opinion  about what the dangers are. What has happened over and over again with  these instruments is that people have assumed that there is measurable  risk where in fact there is immeasurable uncertainty.
