Many commentators like to speculate on where the dollar-denominated gold price is ultimately headed. Some claim that it is destined to reach $3,000/oz, others claim that it won’t top until it hits at least $5,000/oz, and some even forecast an eventual rise to as high as $50,000/oz. All of these forecasts are meaningless.

Long-term dollar-denominated price targets are meaningless because a) they fail to account for — and cannot possibly account for, since it is unknowable — the future change in the dollar’s purchasing power, and b) the only reason a rational person invests is to preserve or increase purchasing power. To further explain by way of a hypothetical example, assume that five years from now a US dollar buys only 20% of the everyday goods and services that it buys today. In this case, the US$ gold price will have to be around $6,500/oz just to maintain its current value in purchasing power terms. To put it another way, in my example a person who buys gold at around $1300/oz today and holds it will suffer a loss, in real terms (the only terms that matter), unless the gold price is above $6,000/oz in April-2022. Considering a non-hypothetical example to make the same point, in 2007-2009 a resident of Zimbabwe who owned a small amount of gold and not much else would have become a trillionaire in Zimbabwe dollars and would also have remained poor.

The purchasing power issue is why the only long-term forecasts of gold’s value that I ever make are expressed in non-monetary terms. For example, throughout the first decade of this century I maintained that gold’s long-term bull market would continue until the Dow/gold ratio had fallen to at least 5 and would potentially continue until Dow/gold fell to 1.

The 2011 low of 5.7 in the Dow/gold ratio wasn’t far from the top of my expected bottoming range, although I doubt that the long-term downward trend is over. In any case, none of the buying/selling I do this year will be based on the realistic possibility that the Dow/gold ratio will eventually drop to 1. Such long-term forecasts are of academic interest only, or at least they should be.

If I were forced to state a very long-term target for the US$ gold price, it would be infinity. The US$ will eventually become worthless, at which point gold will have infinite value in US$ terms. But then, so will everything else that people want to own.
