Sorry, but I've got to toot my horn on this one. The following link will connect you to the September 23rd, 2007 Econbrowser forum on "Money creation and the Federal Reserve." My post is about one-quarter of the way down on the page. You can find it most easily by doing a word search on the page for "morellid."
I included the link more or less to verify the date I made the observation. So you don't actually have to go there, the following is what I wrote:
"How does the Federal Reserve Bank value the "high-value" securities accepted as collateral. Hypothetically, wouldn't it be unsustainable, if the primary securities dealer, such as Countrywide Financial, uses the increase in reserves to cover a run on assets without using the additional funds to make a productive investment? If the Federal Reserve Bank rolls over the repo to that institution, wouldn't that constitute a feedback loop that ultimately will permanently expand monetary supply and leave the Federal Reserve Bank holding the "high-value" securities (i.e. -- AAA rated CDOs)?"
