Macroeconomic analyst Rob Kirby has 15 years' experience as an international derivatives broker. There are hundreds of trillions in derivatives spread around at the major global banks.
There is no public market, no standards, and no guarantees. If someone miscalculates by a small amount, Kirby says the whole system could crash.
Kirby explains, "You've got one bank in Germany that's got a derivatives book that is 20 times the size of Germany's GDP . . . . Germans have seen their currency go to zero. Germans know this can happen because it's happened to them.
