JMO; if the past rumoprs were true there is no way to return the lent, leased, swapped, papered over, stolen, sold gold to Ft Knox without a price way above today's price.
I doube seriously if the gold was removed from Ft knox, that it was just sitting in someone's den waiting for the day or return, unless it went to Madoff. The estimates of physical gold necessary to cover the S/D deficit over the last years is something like twice the total amount og gold in Ft K.
The amount of gold mobilized to suprress the price over the last 13 years is imense. If a fraction was being supplied from Ft knox it would still be a lot of gold. There would be no way to buy it without an explosion in price or transport it into Ft Know without a video showing up on the web.
I would be happy to be wrong, but this just doesn't pass the smell test.
