Such a thing can't ever happen because:
1. Derivatives are bought and sold by the smartest guys on earth and they can be trusted to know what they are doing.
2. Whatever it is they're doing, don't dare call it speculation, you goldurn commie!
3. Even if there are some speculators (only a few, trust us) then there are an even number of them on either side of the trades so it'll all turn out OK in the wash, trust us.
4. Derivatives never ever led to a bubble. It's only when the government interferes that we have to worry.
5. And BTW, most of the derivatives are sold OTC so we don't even know how many there are out there and they say ignorance is bliss. And last time I checked bliss was a good thing.
Spot on.
