The GSE's awesome crappy mortgages were hurt by other mortgages? Weird.
They weren't crappy mortgages. Delinquency rates were the same or better during the mortgage bubble. GSE's saw delinquencies the same that non-GSE, non-prime loans saw. The chart is the proof. Why are you so allergic to the chart? Why do you argue as a sophist? There's no reason to. At this point, you're doing more harm to your cause.
But GSE's didn't cause the private label market to collapse.
Who said they did?
YOU DID! Originally, you did. Then you shifted the goalposts as you became more informed. Now, I don't even think you know what argument you're making because every time you post, it just seems like you're flailing more and more, trying to land a punch of some kind. That's why you argue as a sophist, as I pointed out above.
So if GSE's didn't cause the collapse,
what did?
GSE purchases of crappy loans helped inflate the bubble, not surprising the collapse hurt the buyers of crappy loans.
BULLSHIT! GSE market share was cut
in half during the bubble years of 2004-7. They weren't inflating the bubble. They weren't even
helping to inflate the bubble. GSE loans performed the same, or better, than they did prior to the bubble. They only entered delinquency as a consequence of the bubble burst, which was driven by those private-label subprimes. I'm going to keep posting this chart until you accept it, or reconcile it:
GSE loans performed better than private-label loans, as the chart shows.
They bought a better class of crappy loans than some. So what?
The loans they bought were no better or worse than the ones prior to the bubble.
That's the point you are missing. You have this inherent belief that GSE loans were crappy. They weren't. Clearly, the chart above proves they weren't. In fact, the chart above shows GSE-backed loans performed the best, even before the bubble started. The chart goes all the way back to 1998. Since 1998, GSE-backed loans performed better
than all other loans.
So your attempt to pin the blame of the mortgage bubble, even partially, on GSE's is wrong.
50% or more of the GSE purchases were from the dodgy end of the pool, of course they contributed to the bubble.
You sure about that? Because GSE loans defaulted at rates much, much lower than those of private labels. In fact, you allege the loans they bought were "dodgy", but those loans didn't default in 2006, like the private-label subprimes did. In fact, GSE loans defaulted at rates below 3% during the bubble while everyone else had much higher default rates. Again, this is in the chart. Not sure why you have such a hard time accepting it.
