My tinfoil hat says that derivatives exposures are all a part of the globalists plan to collapse the world economic system to drive us to a one-world currency. It' a piece of the puzzle; another piece being to ensure every country is in some form of debt to everyone else. That way when it all falls apart - when can do a massive "do-over."
When derivatives start to go it becomes a chain reaction, like a nuclear detonation, and it can’t be stopped until the explosion occurs.
