with $billions must have a game plan. After all he does have a track record.
Let's see, how about buying a boatload of GLD ETF and letting the world know about it....of course he only has to put down 5%. George knows the boys don't have the gold but he has made a deal with them because the optics were timely for the GLD boys. You would think that the GLD boys would know that George is one step ahead of them but desperation can do knee jerk things to people. George lets it ride for a month or two. Of course, George has a ton of gold bullion stashed in vaults elsewhere(leveraged no doubt) and a very healthy basket of the best gold stocks money can buy...via various means. That's a secret.
One day soon George may call the GLD boys and tell them he wants delivery on his certificates. If that is inconvenient, he will settle for cash plus 50%. If they can't manage that (but they should have no trouble with a printing press pass) then there is a mammoth default and gold and all the shares he owns will go nuts, probably by more than 50% in short order. No matter what, it's a win-win for good old, foxy George.
I realize that's a very simplistic thought bubble for George's gold bubble because the intricacies are far beyond my understanding, but that in essance, might be somewhat plausible. George didn't have any compassion when he nearly brought down the pound sterling so I can't see him being nervous about taking down GLD ad the COMEX.
Just a wild theory.
