This we apprehend to be the cause why the rate of interest in this country was so high as it is well known to have been during the last war. It is, therefore, by no means to be inferred, as some have done, that the general rate of profits was unusually high during the same period, because interest was so. Supposing the rate of profits to have been precisely the same during the war, as before or after it, the rate of interest would nevertheless have risen, from the causes and in the manner above described. The practical use of the preceding investigation is, to moderate the confidence with which inferences are frequently drawn with respect to the rate of profit from evidence regarding the rate of interest; and to shew that although the rate of profit is one of the elements which combine to determine the rate of interest, the latter is also acted upon by causes peculiar to itself, and may either rise or fall, both temporarily and permanently, while the general rate of profits remains unchanged. * * * * * The introduction of banks, which perform the function of lenders and loan-brokers, with or without that of issuers of paper-money, produces some further anomalies in the rate of interest, which have not, so far as we are aware, been hitherto brought within the pale of exact science. If bankers were merely a class of middlemen between the lender and the borrower; if they merely received deposits of capital from those who had it lying unemployed in their hands, and lent this, together with their own capital, to the productive classes, receiving interest for it, and paying interest in their turn to those who had placed capital in their hands; the effect of the operations of banking on the rate of interest would be to lower it in some slight degree. The banker receives and collects together sums of money much too small, when taken individually, to render it worth while for the owners to look out for an investment, but which in the aggregate form a considerable amount. This amount may be considered a clear addition to the productive capital of the country; at least, to the capital in activity at any moment. And as this addition to the capital accrues wholly to that part of it which is not employed by the owners, but lent to other producers, the natural effect is a diminution of the rate of interest.
