The banking system's management structure, comprising the IMF, the Bank of International Settlement, and sovereign central banks, they are all very heavily involved with gold, both the stock, and the flow.
So far I have not found any evidence about their interest in silver.
The biggest gold owner is Eurosystem Central Bank with 10300 tons, the US Treasury comes second with 8100 tons (I'll take their word for it for now). Russian Central Bank declared their intention to increase gold reserve consistently, and I believe PBOC is also accumulating gold.
The central banks will be the market maker for gold in my endgame senario.
Who will be the market maker for silver when the banking/monetary system is on the brink of collapse?
