Why is this you might ask? Silver is poor man's gold, making it the 2nd best ultimate form of currency. When gold is over $2000/oz, it will be unaffordable for most people to buy much gold to protect themselves. But at that point if the gold/silver ratio is still around 60, the price of silver will be a much more affordable $33/oz. I suspect that the ratio will be a lot lower by then. Furthermore, because the relative price of silver is much lower than gold, it is more "fungible," meaning it's more practical as a currency for everyday mundane use.
The chart below - inspired by DC from NJ - is another way of measuring the relative strength of silver vs. gold. As you can see, silver has been in a steady climb in price relative to gold and is currently chewing thru a lot of "resistance," as defined by the two horizontal black lines. Hedge funds currently like to "game" the gold/silver ratio, which may slow down the ultimate price movement of silver against gold. However, given that the total market value of all the available silver in the world is small compared to gold, when the "poor man's gold" effect really takes hold, expect the price of silver to really rocket higher. Eventually that ratio will decline to a level that is much more consistent with the ratio that held for centuries.
