Some of these slides are from my previous blog site, when I was considering some of the policy decisions and data from the first Great Depression in the US. This study was from 1999 to 2001. It was fully fleshed out in my mind by Bernanke's (in)famous essay of 2002, The Fed Has a Printing Press. That pretty much cleared the air for me on the future investment path for gold.
Although I do not list it here, you may also be interesting in the posting, Why the Feds Seized the Gold in 1933. The purpose was to devalue the dollar AND to use the proceeds to recapitalize the banks that were remaining after the FDR bank holiday.
Since the US is not on a gold standard now, the Fed has no need for the gold. It can expand its balance sheet with a few keyclicks, as long as that is their policy decision. Any wide scale confiscation of private property at this point would be purely gratuitous and rather unlikely, recent hysteria not-withstanding.
