The challenge for Ben Bernanke and the Fed governors since the 2008 bailouts has been how to deal with the backlog of fraud – not just fraudulent mortgages and fraudulent mortgage securities but the derivatives piled on top and the politics of who owns them, such as sovereign nations with nuclear arsenals, and how they feel about taking massive losses on AAA paper purchased in good faith.
On one hand, you could let them all default. The problem is the criminal liabilities would drive the global and national leadership into factionalism that could turn violent, not to mention what such defaults would do to liquidity in the financial system. Then there is the fact that a great deal of the fraudulent paper has been purchased by pension funds. So the mark down would hit the retirement savings of the people who have now also lost their homes or equity in their homes. The politics of this in an election year are terrifying for the Administration to contemplate.
