Okay IHBer's gather around, it is time for graphrix to review risk based pricing for MBS. As some of you know, I kinda know what I am talking about, not always being a nutter and all, but for the most part on this subject, I do. For some of the newer people, I recommend doing a search for some of my posts on this subject. In fact, in my 2000 comment thread I referred to a post about risk based pricing, and ironically that was before the subprime blow up and it basically predicted what would happen. Also, I highly recommend reading the <a href="http://calculatedrisk.blogspot.com/2007/07/compleat-ubernerd.html">three posts on MBS from Tanta</a>.
First, you have to understand that most jumbo loans have been underwritten by Fannie Mae or Freddie Mac guidelines, since well before the August crunch. Granted, there may have been a few exceptions made, but for the most part they had to "conform" to the same guidelines as "conforming", except that the loan amount was larger. I am not talking about ALT-A, I am talking about plain ol' A-paper jumbo loans.
Now, come August investors no longer wanted jumbo loans, and the pricing skyrocketed. It has since come back down to a more reasonable spread compared to conforming, but the spread is still higher than normal. What this means, are the investors want and are demanding a premium for the amount of risk they are taking on. The defaults on jumbo loans has increased significantly, and this is not just a subprime/ALT-A problem. It is a problem, that people can't afford their mortgage.
So here is what happens... Fannie raises the loan limit to $625k. Woo hoo! The bottom is here, everyone can buy home now, YAY! Oops... sorry about that, I had a kool-aid flashback there. Well, when Fannie does this, and they price the loan the same as all their conforming loans, when they go to sell it, the investors will balk. They will say we aren't buying that crap for that price, we have been buying it for the last two years, and it is crap. So, Fannie will have to take a loss on the sale, since they can't get the price they thought it was "worth", and now they will have to raise the risk based pricing. What does this mean? They have to add a risk based fee to the loan amounts above $417k. Just a guess here, but lets say for loans above $417k to $525k, there is a 100bps hit in fee, and for loans above $525k, there is a 150bps hit in fee. The hit is in the fee, or the yield spread, and not the rate.
What that looks like today, at one wholesale lender (and, this isn't to discuss what rates are and where you can find better, but for consistency of pricing. If you want to discuss rates, then there is a thread for it, but not here.)...
A conforming loan up to $417k, would have a rate of 5.75% for 0 points.
A conforming loan between $417k and $525k, would have a rate of 6.25% for 0 points.
A conforming loan between $525k and $625k, would have a rate of 6.75% for 0 points.
So, look at it this way... a $625k loan at 5.75% would have a payment of $3647 (roughly an income of $205k to qualify), and at 6.75%, would have a payment of $4053 (roughly an income of $220k to qualify).
Is it just me, or does increasing the loan limit look like it won't do sh*t to help the market? Or, do I just sound like a nutter? It's okay to call me a nutter, I am used to it, but a nutter who has been right is better than being normal and wrong.
And, do not even get me started on how this really hurts the GSEs capital requirements, that they are already on the brink of breaking.
