True, but the stockpiles (Nickel for example) will have to decrease.

The USD will have to sink. When investors who got scared out of stock exchange will realize that T-bonds are not profitable anymore, they will turn to PM. As the USD goes down commodities will automatically rise as well as inflation. This process will take time but things are moving faster today than they did 80 years ago. The problem is that investors are not patient anymore. Their problem is that there is no more quick fix to make money. Waiting is the key word today.
