Lack of Central Control
[281]There is no country in the world where the volume of currency in circulation and the demand for bank credits fluctuate more widely than in the United States. This is due to the great expanse of our territory, to the annual harvest requirements of the agricultural sections, to the prevailing business activity and enterprise, and to the rapid and unequal increase of population and wealth in different sections. Furthermore, there is no country in the world where intelligent control over bank credits and bank reserves is needed more than in the United States. There are in the United States nearly seven thousand national banks, besides twice as many state banks and trust companies. Each of these institutions acts for its individual interest alone, independently of the others, and the prevailing tendency of each at all times is to expand its credits to the limit permitted by law. The country banks lend their surplus resources in the form of deposits at interest to the banks in the larger cities, and the banks in the principal money centres commonly expand their credits as much as practicable by lending on call such sums as they deem it unsafe to lend on time or by discount of commercial paper. Each bank with a deposit in another bank assumes that, in case of need, it can strengthen its reserve by drawing upon this deposit; but it fails to consider that, when thus it strengthens its own reserve, it must to the same extent weaken the reserve of the other bank, and that the deposits of banks with other banks add no strength to the general credit situation. Each bank that has loaned money on call assumes that, in case of need, it can strengthen its reserve by calling such loans; but it fails to consider that, generally, when a loan is called the borrower is obliged to borrow the same sum from some other bank, although a high rate of interest may be exacted, and, therefore, that call loans affect the security of the entire bank situation practically to the same extent as time loans.
In the United States there is no way of regulating the supply of bank credits and of holding part of the potential supply in reserve for periods of financial stringency. Consequently, nearly always there is either an over-abundance of money (meaning credit which the banks are ready to lend) or a money famine. It has been argued that the volume of credits granted by the banks depends upon business activity and upon the consequent demand for credit and not upon the power of the banks to grant credits, and, therefore, that low interest rates have little effect in causing an expansion of bank credits. Experience, however, shows that the contrary is the case, at least in the United States. It is true that, when there is loss of confidence and when business is depressed, interest rates are low, because there is less currency in circulation and more in the bank reserves, while at the same time the demand for bank credits is diminished. It is true, also, that low interest rates will not stimulate speculation and enterprise unless people have confidence and are ready to speculate and to embark in new enterprises. But we know by experience that when people are in a mood for speculation and for business expansion low interest rates operate as a powerful stimulus to speculation and business expansion. A leading banker has said: "In the long run commerce suffers more from the periods of over-abundance (of money) than from those of scarcity. The origin of each recurring period of tight money can be traced to preceding periods of easy money. Whenever money becomes so over-abundant that bankers, in order to keep it earning something, have to force it out at abnormally low rates of interest, the foundations are laid for a period of stringency in the not far distant future, for then speculation is encouraged, prices are inflated, and all sorts of securities are floated until the money market is glutted with them."[282] [The need of intelligent control over discount rates and bank credits is (was) imperative.]
