Why Gold's Value is Historically Stable

If all Gold Mining operations ceased tomorrow, it really wouldn't make much difference...

SOMETHING that you often hear about gold, as a monetary asset, is that the supply of gold – the amount of gold in the world – increases by about 2% each year due to Gold Mining activities, writes Nathan Lewis, of New World Economics.

We don't really consume gold. Most of the gold that has ever been mined (the US Geological Survey estimates 85%) still exists today as bars, coins and jewelry. Even the small bit that is used in industry is often recycled.

The next thing you typically hear is that a gold standard system works because the "money supply" increases at a stable rate, in line with mining production. In other words, the rate of growth of quantity is stable.

This is totally incorrect. If you look at any historical gold standard system, such as the Bank of England in the 1880s, you find that the "money supply" (base money) is in fact quite variable, and doesn't follow this "2% per year" rule at all.

For example, in 1900, the US monetary base increased to an estimated $1,344 million, from $1,126 million in 1899. That's an increase of 19.4%.

In 1896, however, the US monetary base fell to $944m from $1,022m in 1895, a decrease of 7.6%.

There's nothing stable at all about the "money supply" with a gold standard system. It adjusts, automatically via the value parity, to the economic conditions of the time.

The "stable" part is stable value. The British pound maintained a defined value compared to gold. Gold, likewise, maintained a stable value in part because the supply was very large and stable.

Here is one of our favorite 19th century references, John Stuart Mill, on the subject:

"[O]n the whole, no commodities are so little exposed [as gold and silver] to causes of variation. They fluctuate less than almost any other things in their cost of production. And from their durability, the total quantity in existence is at all times so great in proportion to the annual supply, that the effect on value even of a change in the cost of production is not sudden; a very long time being required to diminish materially the quantity in existence, and even to increase it greatly not being a rapid process. Gold and silver, therefore, are more fit than any other commodity to be the subject of engagements for receiving or paying a given quantity at some distant period."

Let's look at some of the recent specifics. How is gold different than copper?

Almost all the gold ever mined is stored in the form of bullion and jewelry. Copper is completely different. Almost all the copper mined today is used immediately, for some practical purpose. Very little is stored for the long term.

In 2010, world production of copper was estimated at 16.2 million tons. However, known world inventories of copper, on major exchanges, were about 645,000 tons. So, the physical inventory was only 4% of world production. Likewise, industrial demand for copper was also around 16.2 million tons per year.

What if, for some reason, copper mining ceased completely? Obviously, there would only be that small inventory of 645,000 tons available. This would be a big problem.

Now let's look at gold. In 2010, world production of gold was estimated at 72 million troy oz. The amount of gold in the world was about 5.0 billion ounces. So, the production was only about 1.4% of the inventory.

What if world gold production stopped completely? It would mean that we would have 5.0 billion ounces of gold, instead of 5.072 billion ounces. Big deal. That's one reason why gold's value is stable, making it usable as a monetary benchmark.

The World Gold Council produces some statistics on uses of gold. In 2010, the WGC says that there was 2,586 tons of gold produced. The amount used for industrial purposes was 466 tons. The remainder went into coins and jewelry.

Let's look at that: 466 tons into industry, 2,586 tons produced, and roughly 155,000 tons in existence. Industrial demand is only 0.3% of available supply.

Even that industrial demand is largely satisfied from recycling. The WGC says that 1,645 tons were available from recycling in 2010. This includes both industrial recycling and scrap jewelry, but it shows that recycled gold is also a major source of bullion.

We are accustomed, in the US, to seeing gold jewelry that costs much more than the value of the bullion contained. Maybe that's why we own hardly any gold jewelry. It's different in the rest of the world. Most of the gold jewelry in the world is in Asia, notably India. In Asia, the cost of the jewelry is just a bit higher than the value of the bullion contained – about 2% higher on average. In other words, there's about a 2% "fabrication premium" to turn the bullion into something wearable.

Actually, that's about the same "fabrication premium" as we have today for bullion coins like Krugerrands and American Eagles. Most of this jewelry serves the same function as Krugerrands and Eagles serve for us. It is, in essence, a store of monetary value. Plus, you can wear it. Maybe those Asians are on to something.

Gold has been money for thousands of years because its value is stable. The sorts of "supply and demand" issues that affect other commodities are not relevant for gold.
