Visualization of the Golden Cube by Deutsche Bank Commodities Special Report (Sep 2012)

An oft-cited gold trivia is that the volume of all gold ever mined in human history can be represented by a cube that sits neatly on a tennis court. How big exactly would that cube be, and does it really matter if its sides were 20m, 20.5m or 20.7m? James Turk of GoldMoney Foundation thinks it does.

The density of gold is 19.32 grams per cubic centimetre (gm/cc), which is equivalent to 19.32 tonnes per cubic meter (t/m³). The cube on the left would weigh 166,444 tonnes, which is close to Deutsche Bank’s estimate based on World Gold Council (WGC) data.

If the sides were increased to 20.7m, it would weigh in at 171,363 tonnes which is close to the widely reported Gold Fields Mineral Services’ (GFMS) estimate of 171,300 tonnes as at December 2011.

GoldMoney Foundation’s estimate based on a recently published study by James Turk assisted by Juan Castañeda concluded that GFMS has overestimated the cube size by 70 centimeters; Equivalent to 16,056 tonnes, or about $877 billion at $1,700 per ounce.

It is significant because that’s an over estimation of 10.3% or more than fve-times the current rate of annual production.

“The level of global physical gold stocks is important in the context of remonetization of gold, which is likely to become increasingly discussed in time, given the accelerating pace of monetary creation by central banks.” GoldMoney Research Director Alasdair Macleod.

The conclusion of their essay reads:
-

A. The size of the gold stock

Our estimate of the 1492 gold stock is 297 tonnes, which is the calculation of Federal Reserve analysts Velde and Webber. Using this estimate as the starting point, we add to it the annual production data available from various sources, as explained in Appendix 3.

According to the World Gold Council, which is using Thomson Reuters data, the world’s gold stock as of December 2011 was 171,300 tonnes. Our research provides a reasonable analytical framework to suggest that the gold stock as of December 2011 is 155,244 tonnes, meaning that Thomson Reuters GFMS overestimates the existing stock by 16,056 tonnes, or 10.3%.

Given that data provided by the World Gold Council is usually taken as the principal reference on this matter, we conclude that a general perception exists which overstates the current gold stock. The amount of the overstatement is more than fve-times annual production, and at the current price of $1,700 per ounce has a nominal value of $877 billion.

B. The importance of the gold stock

The 155,244 tonnes comprising the world’s gold money stock is gold’s M3. Changes in it compared with the supply of national currencies facilitate comparisons of relative purchasing power as explained by the quantity theory of money.

These comparisons show that gold maintains its purchasing power over time because the gold stock expands in a disciplined way, with the result that its annual percentage increases are remarkably similar, even over hundreds of years. These fairly consistent annual rates of growth are the goal of Milton Friedman’s “k-percent rule”. Thus, the quantity theory of money explains why gold maintains its purchasing power over long periods of time.

In contrast, the stock of national currencies is volatile. Increases/decreases in annual growth rates are the result of man-made factors that cause this volatility in the money stock, which result in fuctuating price levels and the erosion of purchasing power.

C. Gold is money

Even though it does not actively circulate as currency anymore, gold continues to fulfl two important functions of money. It is useful in economic calculation, and it preserves purchasing power over long periods of time.

Gold is not a consumable commodity. Like the dollar, euro, pound and other monies, gold has purchasing power, which can be used to acquire goods and services. Thus, gold’s value arises from its usefulness as money.
