The Theory of Money and Credit - Ludwig von Mises [164]
But the defenders of orthodox banking policy have been no happier in their arguments. They evidence no very considerable insight into the problems lying behind such slogans as "protection of the standard" and "control of excessive speculation." Their prolix discussions are generously garnished with statistical data that are incapable of proving anything, and they devote scrupulous attention to the avoidance of the big questions of theory that constitute the bulk of their subject. It is undeniable that there are some excellent works of a descriptive nature to be found among the huge piles of valueless publications on banking policy of recent years, but it is equally undeniable that with a few honorable exceptions their contribution to theory cannot compare with the literary memorials left by the great controversy of the Currency and Banking Schools.
The older English writers on the theory of the banking system made a determined attempt to apprehend the essence of the problem. The question around which their investigations centered is whether there is a limit to the granting of credit by the banks; it is identical with the question of the gratuitous nature of credit; it is most intimately connected with the problem of interest. During the first four decades of the nineteenth century the Bank of England was able to regulate only to a limited degree the amount of credit granted by varying the rate of discount. Because of the legislative restriction of the rate of interest which was not removed until 1837 it could not raise its rate of discount above five percent; and it never allowed it to fall below four percent. [6] At that time the best means it had of adjusting its portfolio to the state of the capital market was the expansion and contraction of its discounting activities. That explains why the old writers on banking theory mostly speak only of increases and diminutions of the note circulation, a mode of expression that was still retained long after the circumstances of the time would have justified reference to rises and falls in the rate of discount. But this does not affect the essence of the matter; in both problems, the only point at issue is whether the banks can grant credit beyond the available amount of capital or not. [7]
Both parties were agreed in answering this question in the negative. This is not surprising. These English writers had an extraordinarily deep understanding of the nature of economic activities; they combined thorough knowledge of the theoretical literature of their time with an insight into economic life that was based upon their own observations. Their strictly logical training permitted them rapidly and easily to separate essentials from nonessentials and guarded them from mistaking the outer husk of truth for the kernel that it encloses. Their views on the nature of interest might diverge considerably—many of them, in fact, had but the vaguest ideas on this important problem, whose significance was not made explicit until a later stage in the development of the science—but they harbored no doubts that the level of the rate of interest as determined by general economic conditions could certainly not be influenced by an increase or diminution in the quantity
