This is the most important chart of the housing bubble because, while Federally Related Mortgage Pools contributed to the early part of the housing bubble, the real bubble went wild when mortgage originations came from Private-label ABS. Private shadow banks, as the chart clearly indicates, exploded the housing bubble with massive originations and helocs, all allowed by the Fed from plans initiated at Basel 2.
I used this chart in two articles at Business Insider.
One criticized Bill Clinton here.
One criticized the Libertarians here.See also this article as to the intent and fraud of this shift to private shadow bank lending.
This page was originally found here and I corrected the spelling of "chart" on this new page.
