The gold price began its long tanking soon after Germany requested 300 tonnes be returned from New York They were told it would take SEVEN YEARS What if the gold was all leased out and bullion banks had to buy back 300 tonnes on market ? Damn good incentive to push the price down if there ever was one http://www.mauldineconomics.com/ttmygh/what-if
I've said just the same previously. The *ONLY* reason you would take 7 years, and refuse inspection of someone's gold is simply that you don't have it any more. Remember, in any puzzle, it's usually the simplest/most obvious answer that's the correct one.
