KEY TO SILVER PRICE

Keep one thing in mind: the key to the silver price is monetary demand.

My question: Whose monetary demand?

For gold, it is the system. The banking/monetary system itself needs gold to recapitalize the system itself. This can be seen through the actions of the central banks.

Central banks (amongst others) are buying gold now .

Who is  buying silver now? Investors and speculators, and industrial/commercial users.

I see a big problem/contradiction putting these two statements together:  

1. the key for silver is Monetary Demand, and

2. Central banks are not buyers.
