The Monetary Breakdown of the West
The Classical Gold Standard, 1815-1914
We can look back upon the "classical" gold standard, the Western world of the nineteenth and early twentieth centuries, as the literal and metaphorical Golden Age. With the exception of the troublesome problem of silver, the world was on a gold standard, which meant that each national currency (the dollar, pound, franc, etc.) was merely a name for a certain definite weight of gold. The "dollar," for example, was defined as 1/20 of a gold ounce, the pound sterling as slightly less than 1/4 of a gold ounce, and so on. This meant that the "exchange rates" between the various national currencies were fixed, not because they were arbitrarily controlled by government, but in the same way that one pound of weight is defined as being equal to sixteen ounces.
The international gold standard meant that the benefits of having one money medium were extended throughout the world. One of the reasons for the growth and prosperity of the United States has been the fact that we have enjoyed one money throughout the large area of the country. We have had a gold or at least a single dollar standard with the entire country, and did not have to suffer the chaos of each city and county issuing its own money which would then fluctuate with respect to the moneys of all the other cities and counties. The nineteenth century saw the benefits of one money throughout the civilized world. One money facilitated freedom of trade, investment, and travel throughout that trading and monetary area, with the consequent growth of specialization and the international division of labor.
It must be emphasized that gold was not selected arbitrarily by governments to be the monetary standard. Gold had developed for many centuries on the free market as the best money; as the commodity providing the most stable and desirable monetary medium. Above all, the supply and provision of gold was subject only to market forces, and not to the arbitrary printing press of the government.
The international gold standard provided an automatic market mechanism for checking the inflationary potential of government. It also provide an automatic mechanism for keeping the balance of payments of each country in equilibrium. As the philosopher and economist David Hume pointed out in the mid-eighteenth century, if one nation, say France, inflates its supply of paper francs, its prices rise; the increasing incomes in paper francs stimulates imports from abroad, which are also spurred by the fact that prices of imports are now relatively cheaper than prices at home. At the same time, the higher prices at home discourage exports abroad; the result is a deficit in the balance of payments, which must be paid for by foreign countries cashing in francs for gold. The gold outflow means that France must eventually contract its inflated paper francs in order to prevent a loss of all of its gold. If the inflation has taken the form of bank deposits, then the French banks have to contract their loans and deposits in order to avoid bankruptcy as foreigners call upon the French banks to redeem their deposits in gold. The contraction lowers prices at home, and generates an export surplus, thereby reversing the gold outflow, until the price levels are equalized in France and in other countries as well.
It is true that the interventions of governments previous to the nineteenth century weakened the speed of this market mechanism, and allowed for a business cycle of inflation and recession within this gold standard framework. These interventions were particularly: the governments' monopolizing of the mint, legal tender laws, the creation of paper money, and the development of inflationary banking propelled by each of the governments. But while these interventions slowed the adjustments of the market, these adjustments were still in ultimate control of the situation. So while the classical gold standard of the nineteenth century was not perfect, and allowed for relatively minor booms and busts, it still provided us with by far the best monetary order the world has ever known, an order which worked, which kept business cycles from getting out of hand, and which enabled the development of free international trade, exchange, and investment.
