Read this whole thing if you need to start understanding what’s happening in the financial markets and another reason to be anti-McCain.

Just read below if you want the kicked-in-the-genitals part:

How big did this market become? Here’s business correspondent Bob Moon and host Kai Ryssdal on American Public Media’s Marketplace from back in the spring.

BOB MOON: OK, I’m about to unload some numbers on you here, so I’ll speak slowly so you can follow this.

The value of the entire U.S. Treasuries market: $4.5 trillion.

The value of the entire mortgage market: $7 trillion.

The size of the U.S. stock market: $22 trillion.

OK, you ready?

The size of the credit default swap market last year: $45 trillion.

KAI RYSSDAL: That’s a lot of money, Bob.

As in three times the whole US gross domestic product, Bob. And the truth is that Moon probably underestimated. The unregulated and poorly reported credit default swaps may have actually passed $70 trillion last year, or about $5 trillion more than the GDP of the entire world.
