Below is a cumulative tally of how much stimulus has come from the Fed and Treasury over the last four years. The total is now about $7T ($5T worth of deficits plus another $2T worth of monetary expansion). Amazingly, to the extent that one believes that the crisis was primarily housing market related, the $7T total represents ~70% of all the mortgage debt outstanding in 2008.
