The Theory of Money and Credit - Ludwig von Mises [102]
Yet credit money is not merely an acknowledgment of indebtedness and a promise to pay. As money, it has a different standing in the transactions of the market. It is true that it could not have become a money-substitute unless it had constituted a claim. Nevertheless, at the moment when it became actual money—credit money—(even if through a breach of the law), it ceased to be valued with regard to the more or less uncertain prospect of its future full conversion and began to be valued for the sake of the monetary function that it performed. Its far lower value as an uncertain claim to a future cash payment has no significance so long as its higher value as a common medium of exchange is taken into account.
It is therefore quite beside the point to interpret devaluation as national bankruptcy. The stabilization of the value of money at its present—lower—level is, even when regarded merely with a view to its effects on existing debt relations, something other than this; it is both more and less than national bankruptcy. It is more, for it affects not merely public debts, but also all private debts; it is less, for one thing because it also affects those claims of the state that are in terms of credit money while not affecting such of its obligations as are in terms of cash (metallic money) or foreign currency, and for another thing because it involves no modification of the relations of the parties to any contract of indebtedness in terms of credit money made at a time when the currency stood at a low level, without the parties having reckoned on an increase of the value of money. When the value of money is increased, then those are enriched who at the time possess credit money or claims to credit money. Their enrichment must be paid for by debtors, among them the state (that is, the taxpayers). Yet those who are enriched by the increase in the value of money are not the same as those who were injured by the depreciation of money in the course of the inflation; and those who must bear the cost of the policy of raising the value of money are not the same as those who benefited by its depreciation. To carry out a deflationary policy is not to do away with the consequences of inflation. You cannot make good an old breach of the law by committing a new one. And as far as debtors are concerned, restriction is a breach of the law.
If it is desired to make good the injury which has been suffered by creditors during the inflation, this can certainly not be done by restriction. In the simpler circumstances of an undeveloped credit system, the attempt has been made to find a way out of the difficulty by conversion of the debts contracted before and during the period of inflation, every debt being recalculated in the devaluated money according to the value of the credit money in terms of metallic money on the day of origin. Supposing, for instance, that the metallic money had been depreciated to one-fifth of its former value, a borrower of 100 gulden before the inflation would have to pay back after the stabilization, not 100 gulden, but 500, together with interest on the 500; and a borrower of 100 gulden at a time when the credit money had already sunk to half of its nominal value, would have to pay interest on and pay back 250 gulden. [8] This, however, only covers debt obligations which are still current; the debts which have already been settled in the depreciated money
