"While gold is a main focus of the Central Bank market rigging apparatus, physical silver investment demand is their real enemy. The reason is simple. Central Banks have gold in their vaults to dump on the market (or to lease) to control the price, but they have very little if any silver for this purpose.
We must remember, Gold and Silver go hand in hand. If one is controlled, so must the other. If the price of silver got out of hand and skyrocketed higher, for whatever reason, it would impact the price of gold as well."
