Let's Try Simplifying Credit Default Swaps

One explanation you hear a lot today to explain the current crisis is how complex it is, because the financial instruments being used are so darn new and complicated. Let's examine that, and see if passes our common sense smell test.

Now, I like to simplify things. Take bonds. The trading of bonds can remarkably complicated, however, in general, bonds aren't. In my mind, bonds are loans. I loan you $10, and you pay me interest for some period on the $10 and, at the end of the period, you give me back the $10. Not too complicated.

The main problem in this transaction is will you give me back my $10, and will you pay me interest while you have it. If you can't do these things, I'm out of luck. So, like any loan, I need to know or assess how likely it is that you can pay me. Sometimes, there are third parties who will tell you the probability of the loan being paid back. Pretty straightforward, even though trading bonds is complicated stuff.

Now, take credit default swaps. Let's buy one. I've lent money to someone to buy a house. In case they can't pay me, I buy an insurance policy and pay premiums on it. Like any insurance, I need to know or assess how likely it is you will pay me if the borrower can't pay me. Just like bonds or any insurance, it's pretty straightforward. How you'll pay, how much, etc., are just details. And, again, trading them can be complicated, though not unknowable.


Now, suppose I buy insurance on a house I don't own. Does that pass the smell test? I didn't think so. Case closed.

Lollers.

I still want to buy insurance on my ex-wife. Does she have to know?

That's funny. But seriously: How the hell do I know?
