2) Comparison of the price rises in gold and silver: This is also obtained from a Seeking alpha article. The figure shows that the relative growth of gold is well within 1 standard deviation (which is considered normal), while silver is off the charts.


3) Price of Gold needed to cover the US money supply: This graph intends to show the required rise in the price of gold to compensate the amount of money floating in the markets (say if the currency was supported by the gold standard). But basically, it shows that even in comparison with the issued money, and mined gold, the current price per ounce of gold is in limits.


5) Current holding of gold in pension funds: Is still very less, hence there is a potential for rise in this percentage.



Important to remember that the correlation does not imply causation. But in this case, as long as the correlation holds, things should be fine.
