Electrum is a gold and silver alloy found in nature, with traces of copper, platinum and other metals. Thus begins the story of this very long and close relation between gold and silver. It is said that a picture is worth a thousand words, so let us analyze this relation between gold and silver with some graphs.

Graph #1 shows why gold, silver, platinum and palladium are considered precious metals, by comparing them to other metals such as copper and nickel. The abundance of non-precious metals is obvious. Copper is 800 times more abundant than silver, which is the most abundant precious metal.

If we take a closer look to precious metals in graph #2, we observe that gold is rarer than platinum and that silver is the most abundant one. The gold/silver ratio is 19/1, whereas the platinum/gold ratio is 1.25/1. Even though platinum is 1.25 times more abundant than gold in the Earth’s crust, 16 times more gold is extracted than platinum.

In regards to the relationship between gold and silver, we observe great variations in the ratio. Even though there is 19 times more silver than there is gold in the Earth’s crust, only 9 times more silver than gold is extracted today. The historical 15/1 gold/silver ratio is closer to their abundance ratio of 19/1. One must not forget, however, that the historical 15/1 ratio has always been fixed or imposed by the state, one-way or the other, and never by the markets.

Relative mass proportion ratio = 64/1
Abundance in weight ratio in the Earth’s crust = 19/1
Total supply ratio = 7/1
Mining only supply ratio = 9/1
Historical price ratio = 15/1
Actual price ratio = 62/1
Stock/flow ratio = 2/1

 

Let us take a closer look at the stock, supply and demand factors for gold and silver, to see if they can justify the historical ratio of 15/1 or the actual market ratio of 62/1. If we look at graphs #4 and #5, we realize that the silver stock is twice the gold stock. However, it is important to know that the silver stock is much harder to get back into the market than gold’s, because it is not stored in its simplest form, contrary to gold. A lot of silver is wasted.

If we study the gold and silver supply, we observe that the total silver supply in relation to gold is 7/1, and the mining supply ratio is 9/1. 60% of the gold market and 75% of the silver market are fed by mining production.

50% of silver’s demand is industrial, whereas industrial demand for gold represents only 10% of the market. It is important to know that industrial demand consumes the metal and makes it hardly recoverable and, consequently, costly in terms of time and money.

According to Ted Butler, silver market analyst, known silver reserves have shrinked 95% since the end of World War II. This is due to a persistent deficit between supply and demand that is continuing today. This known deficit is remarkable, since there has been steady growth of silver world production in the last 50 years, but not enough to satisfy growing industrial demand.

Now, let us compare (graph #5) the stock/flow ratio of the two precious metals. It is approximately 2/1 in relation to the total market or the mining production. This means that the stock is twice as menacing in the gold market than in silver’s and, once again, this stock is much more liquid than silver’s. Moreover, the silver stock is quickly dwindling, whereas gold’s is practically constant, or augments only slightly.

Graph #6 shows us the gold/silver price ratio since 1260, that is 750 years of history. We can see that the ratio has stayed almost constant for about 600 years, around 15/1. This is because it has been fixed by the state and not by the market. Since the moment when silver lost its monetary aspect, it has become a simple commodity. On the other hand, gold has remained a monetary metal, and its price has been officially fixed until 1971. Since gold and silver prices became free, we can observe that the ratio started to fluctuate enormously, going from 10/1 to close to 100/1. However, one must not neglect the fact that, even if the gold price is not fixed officially anymore, it still is a monetary metal for central banks, whereas they own almost no more silver. The relation between gold and silver changed around 1876, when the bi-metallic standard ended. Silver then stopped to be a medium of exchange, while gold remained the currency of last resort and a store of value.

Since the gold price is no more fixed, the ratio has fluctuated between 10 and 100, without indicating a trend or a cycle. This can be explained, as far as I am concerned, by the fact, that the two metals have different stock, supply and demand parameters that determine their prices and one must, consequently, study them separately.

However, there is one exception (see graph #8), because there is a great correlation between the prices of gold and silver. It is the highest correlation of any metals, and it has been 72% in the last five years. This, I think, can be explained by the fact that we are in the midst of a financial crisis and that a collapse of the present monetary system is probable. This has caused a staggering rise in the price of gold that was followed by a transfer of funds toward silver by those who couldn’t afford to buy gold. This is the reason why silver is called ?poor man’s gold?. The higher the gold price, the higher the correlation with silver.

Silver’s price never moves independently from gold, despite its fundamentals. Silver’s monetary aspect dictates its price at this moment. Silver investors are much the same as gold investors, in that they focus mainly on the monetary aspect of silver, instead of its industrial aspect. If gold ever makes a return in the international monetary system, silver will be traded as a currency, though it
