Gold and crime go hand in hand… The schemes that spook the gold trade can’t be sorted out so simply. They are the shadowy events, the phantoms rippling through the tall grass of the business, not clearly visible or understood, and sowing panic for that very reason. One such passage shook the market for two weeks in July 2010, when a massive, unexplained transaction parked a load of bullion in a place where those who monitor such movements did not expect to find it. When they discovered it, their confusion about why it was there was deepened by the stubborn silence of a little known Swiss bank, The Bank for International Settlements, or BIS. Headquartered in Basel, BIS is sometimes called the central bankers’ bank, because that’s where they go to borrow. … The cause of the panic was a footnote to the bank’s annual report. The note revealed that a bank or group of banks had lent 349 metric tons of gold to BIS in exchange for cash. The deal was so colossal — a sixth of the world’s annual production — that the news of it, without elucidation, stunned the bullion market. Who had lent the gold, and why? Was a bank in trouble? Could it be a central bank? What did they know that the bullion market didn’t? As questions thickened the air, investors started bailing out of gold, and the price lost $40 in a day.
