I read this article - shared by Mr. V.T. - and was stunned, and, I suspect you will be too, particularly in the context of those stories about gold repatriation that we've been following over the past few years. You'll recall that the whole "repatriation" game wa kicked off by the late Venezuelan President, Hugo Chavez, when he repatriated some of that country's gold. Others quickly jumped on the bandwagon - Ecuador, Austria, the Netherlands - and then it became serious when Germany wanted to repatriate its gold from the New York Federal Reserve, from Paris, and from London. You'll recall that when that happened, there was a great deal of thumb-twiddling, stuttering, hemming and hawing from all parties concerned, including the Bundesbank, but the bottom line was that Germany did not recover very much. Then China and India and Russia started buying the stuff in record amounts, only to find (in China's case), that some of the bars, at least on the commercial markets were filled with tungsten.
