Qualitative Credit Theorists Joined the Austrians in Opposing the Bank Credit Inflation of the 1920s and in Warning of Impending Depression

Various “qualitative credit” schools, however, also see the depression as inevitably generated by an inflationary boom. They agree with the Austrians, therefore, that booms should be prevented before they begin, and that the liquidation process of depression should be allowed to proceed unhampered. They differ considerably, however, on the causal analysis, and the specific ways that the boom and depression can be prevented.

The most venerable wing of qualitative credit theory is the old Banking School doctrine, prominent in the nineteenth century and indeed until the 1930s. This is the old-fashioned “sound banking” tradition, prominent in older money-and-banking textbooks, and spearheaded during the 1920s by two eminent economists: Dr. Benjamin M. Anderson of the Chase National Bank, and Dr. H. Parker Willis of the Columbia University Department of Banking, and editor of the Journal of Commerce. This school of thought, now very much in decline, holds that bank credit expansion only generates inflation when directed into the wrong lines, i.e., in assets other than self-liquidating short-term credit matched by “real goods,” loaned to borrowers of impeccable credit standing. Bank credit expansion in such assets is held not to be inflationary, since it is then allegedly responsive solely to the legitimate “needs of business,” the money supply rising with increased production, and falling again as goods are sold. All other types of loans—whether in long-term credit, real estate, stock market, or to shaky borrowers—are considered inflationary, and create a boom-bust situation, the depression being necessary to liquidate the wasteful inflation of the boom. Since the bank loans of the 1920s were extended largely in assets considered unsound by the Banking School, these theorists joined the “Austrians” in opposing the bank credit inflation of the 1920s, and in warning of impending depression.
