Seeing that the Miners could be selling Gold at twice the price if they really wanted to , I guess the paper futures are basically killing the equation of supply / demand in the Au/Ag market, simply by not needing to deliver anything.
Solution I proposed years ago : ONLY those that deal in the REAL THING should be allowed to trade in their respective futures market.
From your link :
Chinese Shanghai Gold Exchange (SGE) physical metal deliveries are at an all-time high having already this year exceeded the full year total for 2013 – the previous record year.
Furthermore, deliveries out of the SGE are rising again as we draw nearer to the year-end with the latest figure for the week ending Nov 20th at 54 tonnes bringing the year to that date total to a massive 2,313 tonnes (as compared with the previous record 2013 full year total of 2,181 tonnes). The year to date figure is equivalent to around 80% of current global new mined production on its own.
