Quote from Traden4Alpha:
You can't have a gold-based currency AND let the price of gold float -- that's a complete contradiction. The essence of a gold-backed currency is that a fixed number of currency units are backed by a fixed quantity of gold. Let the price float and currency units can be created out of thin air by changes in the price of gold.
And in a world where all economic expansion requires new gold (unless you allow fractional reserve banking), the miner of gold become extremely rich. Its no different than our geopolitical problems with black gold or oil (which also can't be created out of thin air but can be mined from certain countries and acquired by productive economies through trade). I doubt that any Western government would cede sovereignty over their currency to the Organization of Gold Exporting Countries.
I understand your position, but you have to understand the components of the gold price.
All commodities eventually wind up selling for the cost of their extraction plus some small premium that makes it economically viable to get the stuff. Every dollar over that small premium amounts to speculation on the commodity in question's price rising in the future due to some circumstance that makes it more valuable, which in the case of any other commodity means some new use for it that will make it more valuable, or some looming shortage due to, as in oil last year, the depletion of the resource.
In the case of gold, the price tends towards the residual premium unless there is, as Bernard Baruch once put it, "a question about the currency".
Call it atavistic, barbaric, or whatever other adjective you want, people will gravitate towards gold in times of crisis because it represents value. It probably costs, these days, somewhere between 400 to 600 dollars an ounce to extract gold. Given that, every dollar over, say, 660 or so represents a premium that gold buyers are willing to pay because, in these times, there is that question about the currency. Every single one.
The spot market in gold doesn't measure jewelry demand: it measures confidence in the world's currencies, which is another way of saying that it measures confidence in how the world is being governed, since currencies are, in this day and age, purely a product issued by the governments of the world.
The gold price has a persistent premium on it because the world, in its collective judgment, thinks the world's governments are not up to the challenges facing them.
A floating gold price doesn't really float: the world's currencies are still being measured in terms of gold, which is why there is, in normal times, a strong negative correlation between the gold price and the price of the world's reserve currency, which for the time being is the dollar. In terms of the gold price, then, all currencies are depreciating. Which explains how a floating gold price is nevertheless consonant with a gold standard.
In short, the gold standard never really went away. It just went underground.
