Lets say you thought interest rates were going up so you went out and
bought a futures contract. If you bought a $10 million dollar futures
contract for 1%, or $100,000, and the interest rates went up, than your
$10 million dollar contract went to $15 million and you are a hero.
But with futures there is no limit to your liability, so if the
contract dropped from $10 million to $5 million, then you are liable for
the $5 million. If American banks bet the futures (derivatives) than the
bailout will be in the tens of trillions. And have no fear, the banks
bet on derivatives.
