From my point of view that Banks have been gathering by the X's/ 100's of tonnes of GOLD year over year since mid first decade,,2001-2010.  Convinces me that an even bigger interest is lurking in the very near time frame for GOLD to make its historic moves in a GOLD Bull move.  IMO Banks are buying against asset to currency valuation and likely for stabilization of currency rates.  Also with stability would come economic infusion based on the public trust in exchange of promissary notes that are GOLD backed certificates.  Much more can be said, but trust in the currency is a very vital point to preceed increased spending in the public markets.  With a GOLD infussion into the vaults of Banks that is a direct fix to the financial world.
