Admittedly, we don't have a crystal ball on that question, but we do know some basic facts that help to explain just how far from its baseline value the yellow metal has come.
Gold's Supply/Demand Profile
According to the World Gold Council, 3.3 billion pounds of gold has been mined from the earth over the course of human history. [InvestingAnswers Feature: 50 Surprising Facts You Never Knew About Gold.]
So with most of the mined gold still in existence, and more gold being taken out of the ground every year, there doesn't appear to be a shortage of supply. For as long as they can sell it for more than it costs to mine or recover it, gold suppliers will do all they can to meet demand.
Global gold demand comes from four main sources:
It's hard to get a true read of how much gold is bought and sold between countries. Some countries have sold off major gold reserves, while others have loaded up on it. Most analysts assume that major governments do not impact gold prices, and the amount of gold sold by governments roughly equals the amount purchased.
In terms of the other three factors affecting global demand, 50% of gold mined annually is used for jewelry, 40% is used as investments/hedges by individuals and financial institutions, and the remaining 10% is used in dentistry, medicine and electronic devices like conductors and industrial connectors.
But like anything else, as prices go up, suppliers use ever-more expensive methods to deliver gold at higher prices, while at the same time end users start looking for cheaper substitutes. Both can have a chilling effect on prices.
As prices rise, gold becomes less attractive to central banks, jewelry buyers and industrial users, some of which substitute other metals with properties similar to gold. Using jewelry as an example, rising gold prices means existing jewelry is turned in and melted down, providing ample supply to the manufacturers of new gold jewelry. But those jewelers must then turn around and find buyers at even higher prices. Eventually, buyers dry up and the gold price finds its top. Buyers will substitute silver jewelry for gold, and there's evidence this is already happening.
The Inflation Argument
So that 40% factor -- as an inflation hedge -- is now an ever more important part of the demand equation. And it's certainly the factor that has caused gold to nearly triple in the past five years to around $1,400 an ounce.
Why has gold become so popular among some investors? Because they fear that current government policies are awfully risky. They note that there are two ways a government with massive budget deficits can meet future obligations: 1) By defaulting on their bonds or 2) by subtly encouraging inflation so assets can rise in value while debts stay constant. Either way, gold would become more valuable.

Their fears have a degree of logic. Germany in the 1920s and Zimbabwe in the last decade showed that a sharply-expanded money supply and crushing foreign debts can lead to runaway inflation. But the fact is, the odds of such an event happening in the United States or another developed country is extremely remote. The simple fact remains that there is still too much idle money sitting around earning low bond yields because investors see risk in stocks, housing and other assets that would otherwise be bought, putting pressure on prices.
In the 1990s, money chased tech stocks. In the last decade, money chased housing. And in this decade, it's chasing gold. Those first two manias ended badly, and gold may be set up for a similar fall. Here's why...
Rising prices of any asset creates an environment for its own downfall. High prices are a cure for high prices. Trees do not grow to the sky.

#-ad_banner_2-#As gold has risen in value, demand for non-investment purposes has begun to fall (as noted above). Rising gold prices has also stimulated supply. The 1990s tech boom led to the appearance of hundreds of new dot-com IPOs. The housing bubble led to the construction of far too many homes, many of which are now empty. And the gold price spike is leading many gold mining firms to re-open mines that were no longer cost-effective when gold was at $500 an ounce. As those re-opened mines crank up, the output of gold will follow suit (after notable output declines in recent years). Rising supply that lacks a commensurate rise in demand sets the stage for falling prices.
Can gold climb yet higher? Sure. Nasdaq stocks were sharply overvalued in the summer of 1999, yet they rose much higher at the end of that year in what's known as a "melt-up." I don't foresee that happening with gold, where we would go from $1,400 to, say, $2,000 very quickly. But that Nasdaq melt-up set the stage for an ugly meltdown when the music finally stopped.
Even if the inflation hawks are correct and inflation re-emerges, it's unlikely to be the sky-high inflation like we saw in the 1970s. In the context of a reasonable rise in inflation, gold bugs are bound to be disappointed. Investors are playing a game of musical chairs, pushing gold higher and higher -- but the music always stops.
