I certainly did ask, and neither of you provided anything. On to the substance, this is from your own link:
"The CFTCs Bank Participation Report shows that one or more US banks held a gross short silver futures position equal to 19.1 per cent of the total number of outstanding contracts in early December. In January the share was 30.2 per cent.
The CFTC only reports data for the US silver futures market, a small corner of the global derivatives market for the precious metal, which is centred in London and largely traded via private over-the-counter deals. The data also do not cover transactions in the physical market.
Analysts and traders said that JPMorgans large short positions on New Yorks Comex exchange, a division of Nymex, were hedges for the banks long positions in physical silver and Londons over-the-counter market.
JPMorgan has invested nearly $3bn over the past two years in its commodities business led by Blythe Masters."
According to the Financial Times, the short positions are hedges for long positions in London. There's the answer to your question.
Your first link talks about the fact that gold is being withdrawn from the depositories. Doesn't this imply that it's being physically delivered to other parties? Don't forget, the dispute was about whether physical delivery ever take places. You all were saying no, no, no, even though the contract doesn't provide for cash settlement; substantial reductions in the inventories of the depositories seems fully consistent with delivery to me.
