The Size of Derivatives Bubble = $190K Per Person on Planet

Via the SiliconValleyWatcher and yes I used their article title.

It gives a break down of the various types of derivatives and their USD value and comes up with a total USD value of outstanding derivatives ...

...the amount of outstanding derivatives worldwide as of December 2007 crossed USD 1.144 Quadrillion, ie, USD 1,144 Trillion.
