Downix is explaining this pretty damn well right now, actually.
I would really appreciate a link to a site where I can find this information. And that site about the Treasury's tools is not it.
The Federal Reserve bank of San Francisco has one of the better websites explaining the structure. You then have to look over the various laws and regulatory changes made to the Fed over the years, and work them backwards.
I am looking specifically for a link somewhere that explains QE the way you explained it here.
The way I understood it was offensive enough. The way you explained it is downright frightening.
You won't find a nice neat packaging it up that I know of. It took me months of research to figure it out.
Perhaps I should put it into a book, the complexities of it are deep enough.
