The price of gold is dominated by investment demand* to such an extent that nothing else matters as far as its price performance is concerned. Investment demand is also the most important driver of silver’s price trend, although in silver’s case industrial demand is also a factor to be reckoned with. In addition, changes in mine supply have some effect on the silver market, because unlike the situation in the gold market the annual supply of newly-mined silver is not trivial relative to the existing above ground supply of the metal.

Given that the change in annual mine supply is irrelevant to the gold price and is not close to being the most important driver of the silver price, why do some analysts argue that the gold/silver ratio should reflect the relative rarities of the two metals in the ground and therefore be 10:1 or lower? I don’t know, but it isn’t a valid argument.

A second way of using relative rarity to come up with a very low gold/silver ratio is to assert that the price ratio should be based on the comparative amounts of aboveground supply. Depending on how the aboveground supplies are calculated, this method could lead to the conclusion that silver should be more expensive than gold. It would also lead to the conclusion that gold should be the cheapest of all the world’s commonly-traded metals, instead of the most expensive. For example, if gold’s relatively-large aboveground supply was a reason for a relatively low gold price then gold should not only be cheaper than silver, but also cheaper than copper.

Another argument is that the gold/silver ratio should be around 16:1 because that’s what it averaged for hundreds of years prior to the last hundred years. This is also not a valid argument, because changes in technology and the monetary system can cause permanent changes to occur in the relative values of different commodities and different investments. For example, when monetary inflation was constrained by the Gold Standard the stock market’s average dividend yield was always higher than the average yield on the longest-dated bonds, but the 1934-1971 phasing-out of the official link to gold permanently altered this relationship. In a world where commercial and central banks can inflate at will, the stock market will always yield less than the bond market (except when the central-bank leadership goes completely ‘off its rocker’ and implements the manipulation known as NIRP). This is because stocks have some built-in protection against inflation. The point is that the ratio of gold and silver prices during an historical period in which both metals were officially “money” does not tell us what the ratio should be now that neither metal is officially money and one of the markets (silver) has a significant industrial demand component.
