Mises Corrected a Fallacy Held by a Leading Official of the Hungarian Soviet Republic Who Assumed that the Valuation of the Monetary Unit Depended on the Wealth of the Country

In the course of speculation in stocks and securities, the speculator has developed the procedure which is his tool in trade. What he learned there he now tries to apply in the field of foreign exchange speculations. His experience has been that stocks which have dropped sharply on the market usually offer favorable investment opportunities and so he believes the situation to be similar with respect to the monetary unit. He looks on the monetary unit as if it were a share of stock in the government. When the German mark was quoted in Zurich at ten francs, one banker said: “Now is the time to buy marks. The German economy is surely poorer today than before the war so that a lower evaluation for the mark is justified. Yet the wealth of the German people has certainly not fallen to a twelfth of their prewar assets. Thus, the mark must rise in value.” And when the Polish mark had fallen to five francs in Zurich, another banker said: “To me this low price is incomprehensible! Poland is a rich country. It has a profitable agricultural economy, forests, coal, petroleum. So the rate of exchange should be considerably higher.”

Similarly, in the spring of 1919, a leading official of the Hungarian Soviet Republic told me: “Actually, the paper money issued by the Hungarian Soviet Republic should have the highest rate of exchange, except for that of Russia. Next to the Russian government, the Hungarian government, by socializing private property throughout Hungary, has become the richest and thus the most credit-worthy in the world.”

These observers do not understand that the valuation of a monetary unit depends not on the wealth of a country, but rather on the relationship between the quantity of, and demand for, money. Thus, even the richest country can have a bad currency and the poorest country a good one. Nevertheless, even though the theory of these bankers is false, and must eventually lead to losses for all who use it as a guide for action, it can temporarily slow down and even put a stop to the decline in the foreign exchange value of the monetary unit.
