I think your take on currencies & gold & silver are correct, the directions each take are not behaving as they should if dollars were the primary medium, it could be overseas holders of dollars completed exchanges and therefor dollar transactions comprise a smaller (more domestic) share of commodity action. This move by the ChiCom's needs to be watched awfuly close though, everything those rotten bastards touch is designed to skim something off for them, so a big caveat emptor to potential customers! Plus, depending upon the size of the margin calls on existing leverages accounts, it will lessen the price increase due to any new demand for physical, but the impact is hard to gage since there as been some purging of neked holdings in at least 3 waves already.
