The Theory of Money and Credit - Ludwig von Mises [5]
It is an unsatisfactory designation of this state of affairs to call it an emancipation from gold. None of the countries that have "abandoned the gold standard" during the last few years has been able to affect the significance of gold as a medium of exchange either at home or in the world at large. What has occurred has not been a departure from gold, but a departure from the old legal gold parity of the currency unit and, above all, a reduction of the burden of the debtor at the cost of the creditor, even though the principal aim of the measures may have been to secure the greatest possible stability of nominal wages, and sometimes of prices also.
Besides the countries that have debased the gold value of their currencies for the reasons described, there is another group of countries that refuse to acknowledge the depreciation of their money in terms of gold that has followed upon an excessive expansion of the domestic note circulation, and maintain the fiction that their currency units still possess their legal gold value, or at least a gold value in excess of its real level. In order to support this fiction they have issued foreign-exchange regulations which usually require exporters to sell foreign exchange at its legal gold value, that is, at a considerable loss. The fact that the amount of foreign money that is sold to the central banks in such circumstances is greatly diminished can hardly require further elucidation. In this way a "shortage of foreign exchange" ('Devisennot') arises in these countries. Foreign exchange is in fact unobtainable at the prescribed price, and the central bank is debarred from recourse to the illicit market in which foreign exchange is dealt in at its proper price because it refuses to pay this price. This "shortage" is then made the excuse for talk about transfer difficulties and for prohibitions of interest and amortization payments to foreign countries. And this has practically brought international credit to a standstill. Interest and amortization are paid on old debts either very unsatisfactorily or not at all, and, as might be expected, new international credit transactions hardly continue to be a subject of serious consideration. We are no longer far removed from a situation in which it will be impossible to lend money abroad because the principle has gradually become accepted that any government is justified in forbidding debt payments
