the reality of the derivative paper market in Gold is that the majority of contracts will be settled in fiat. If a big player had the temerity to demand physical delivery it would break the market and send Gold parabolic. Consequential to that : would be that the govt would step in and a request made to accept fiat settlement, like they did with Buffet when he strangled the Silver market and demanded physical delivery. If they played hardball then a series of mysterious accidents and suicides would possibly occur. This is why we are seeing a big divergence between the paper price and the physical price as physical bullion becomes scarce due to high demand and reducing supply.
