At the moment, the basic industrial and ornamental uses for gold have nothing to do with it. A combination of "flight to safety/quality" from the avowed policies of US and Japanese Central banks to trash their currencies and fear of war and economic troubles are the main fundamental drivers, but at the moment I think the overriding driver is that the commercials have lost control and have found themselves on the wrong side of the trade.
They are running the shorts, in the same way that the shorts were run in the recent equities rally. This one could be a good one though, because the gold market is very thin and the gold shorts are quite large.
