[CROSSTALK] Topic for today is Credit Default Swaps. And I promised you, I've been promising for the whole semester that we could use our same balance sheet structure to talk about credit default swaps. and so now I have to deliver on that promise. so let's just think for, just let me give, give you as a way of motivation, motivating this, have a look here at this What I'm showing on this, on this slide here, this is from the internet, is the, there's a company called market.com and it says, if you can read that, it says, market CDX family of indices is the standard North American in emerging markets tradable credited default swap family of indices world wide. Okay. So they have, these are indices of credit default swaps. Which I haven't defined yet, but it's a. And I'm looking down here and here, you can see there, a key functions, exposure to corporate credits, exposure to diversified portfolio credit, hedge credit risk. We're going to see in what sense credit default swaps can do that. Enhance liquidity in a single name market, the liquidity of the index flows into single name CDS market, we'll be talking about that as, as well. So these are, these are indices, let me show you one of them. So there, this is. and then, and then we're going to get behind this. So, what this is showing is on the left hand you see there basis point spread, basis points. So these are basis points over, over some risk list rating, like a treasury rating and you can see that you have 450 basis points there, is the, is the lowest one and 580 is the largest. So these are, these are credit spreads okay, these are corporate bond rates. That are that many basis points, okay, over, over, over treasury rates. So these are not triple a bonds that we are talking about here. In fact, CDXNAHY stands for, this is the corporate bond index, North America, high yield. High yield means junk bonds, okay, is, is what it means. And the, you can see the index spread is red. So, there's fluctuation in that spread from 27th of September, this year to, to now. Fluctuation that's spread. And they create an index which moves inversely to that, which they set at 100 in that index, is approximately. look like it lines up with about 530, okay. So, their, their, their setting the index so that it fluctuates and the, and you can write CDS against this and so forth. Let me just show you one more thing about that. Constituents here, so, this is an index and what's in the index, here you can see, oh it slides over there, maybe it does it better on this side, yeah. You can read it on this side. You can see the different companies, there's 100 different companies there, there's the reference obligation, you can see the rating of this. They're b, double b, triple c, okay so these are low ratings okay. These, these, these bonds. and this is the percentage weight in the index, so there's 100 of them, each one is 1% weight in, in the index. and this is the, this is the kind of object that's underlying credit default swaps for the lecture today. Have in mind that we're thinking about a corporate bond that has a lot of credit risk. Okay, and a credit default swap is a way of peeling that risk off and selling it separately, just as an interest rate swap. Is a way of peeling off interest rate exposure and selling it separately. Okay, so that's just to have in your mind.
