Readings in Money and Banking / Selected and Adapted

by Chester Arthur Phillips

It is, of course, not true that the banks ordinarily allow their reserves to run as low as the legal limit, or make the utmost possible use of the privilege of counting claims against one another as legal reserves. Nor is it accurately true that all forms of money are of equal efficiency in the support of credit. Not all forms of money, but only those of the higher levels in the money scale, are allowed to be counted as legal reserves.... Some forms of money make demands upon other forms for redemption, or are limited in exchange power to the exchange power of the form in which redemption is to be made. The total exchange efficiency of the money of a country is, then, not accurately to be computed on the assumption that all moneys are equally efficient for all purposes—that some are not in varying degree burdens upon the money functions of the others.

Banking Viewed in Detail and in the Aggregate.—And one further modification is called for. The analysis so far made, while valid for any isolated bank, or for the banking system regarded as an aggregate, is not precisely accurate for the affairs of any one competing bank among other banks. When the check drawn by the borrowing depositor may be deposited in other banks and collected by them against the lending bank, its granting of credits rapidly draws down its reserves to swell the reserves of its competitors. One hundred thousand dollars of new reserves may not mean to it an increase of lending power of more than, say, $125,000. For banks in the aggregate, however, this increase of reserves brings its full several-fold increase of lending power, provided that all the reserve efficiency is utilized in whatever bank it rests. As the lending by each bank is depleting its reserves, the lending which other banks are doing is reinforcing these reserves. The aggregate possible extension of credit is not changed.

What Banks Actually Do and Lend.—It follows from the foregoing analysis that, in the main, banks do not lend their deposits, but rather, by their own extensions of credit, create the deposits; that these deposits are funds which the deposit-creditors of the bank can lend if they will, and that many men into whose hands these deposits fall through transfer are certain to use them as funds to be lent. In fact, also, even when the deposits in the bank are not derived from the lending activity of the bank, but are really funds deposited from outside sources, these funds are commonly used by the bank as a reserve basis on which loans are extended rather than as funds which are themselves loaned out by the bank. Banks are, in truth, mostly intermediaries between debtors and creditors—but not in the sense of borrowing funds from one class of customers in order to lend them to another class, but rather in the sense of creating for their borrowing customers funds which may be used by these borrowers as present purchasing power. The borrower becomes indebted to the bank in order that for his own purposes he may use the promise of the bank as the equivalent of cash to himself. In the form of a deposit liability the bank becomes a debtor to whomever the borrower shall nominate. The fact that the borrower pays interest while the bank undertakes a noninterest-bearing obligation, or pays relatively low interest, explains in the main the gains attending the business of commercial banking.

Deposits and Solvency.—It is, therefore, a sheer blunder to infer that a bank is rich or strong because of its great total of deposits, or to regard deposits in banking institutions as making part of the aggregate wealth of the community. Instead, the deposits indicate for a bank the extent of its operations, and indicate for a community the extent to which the banks, under the guise of noninterest-bearing obligations, have assumed the debts of business men, on terms of these business men becoming debtors—and interest-paying debtors—to the banks. The solvency of the bank is in its portfolio of securities. Its deposits are not its assets, but its liabilities. These liabilities it has mostly created for the use of its borrowers. The further it may safely go in assuming liabilities, the larger its holdings of borrowers' notes may be, and the more interest or discount charges it may collect. Essentially, therefore, the business of a bank is a form of suretyship—the guaranteeing of its borrowers' solvency—an underwriting of the credit of its customers. The bank transfers its customers' prospective future paying power into present funds. It is for this reason that the contract takes the form of a money loan and the premium the guise of an interest payment.

Bank Loans Related to Currency and Loan Funds.—And note now that it is precisely because the business of a bank is to furnish to its borrower a present purchasing power for his own use that the business of banking becomes the source of the larger part of the circulating medium of society. In their service to their customers the banks create currency; and in creating currency they create loan funds which, in the hands of the holders of them, are available like other currency for any purpose, either lending or other.

The Sources of Currency Supply.—It is, then, clear that the larger part of the circulating medium of society is not money; that not all of the money that there is is bullion money; and that not even all of the bullion money need be ultimate money—redemption money of the highest rank. The sources of currency in society are various—some of it bullion, with a cost of production limit upon its supply, some of it government paper, substantially free of cost, some of it banking credit with certain peculiar and appropriate costs attending its issue.

Currency and Its Cost of Production.—It is obvious that the actual limitations upon the supply of exchange media must be made clear if we are to understand the influences which are fundamental to the exchange values of the currency unit. Only, indeed, by this investigation of the sources of the supply, and of the terms on which each different factor of the supply is available, are we in position to understand the influences which impose upon bidders for money a certain level of sacrifice in obtaining it.

What, then, are the limitations upon the supply of credit currency supplied by the banks? In other words, what are the banking costs in the granting of demand deposit rights to customers? Evidently limitations there must be, and limitations in the nature of costs, else the competitive activity of the banks would indefinitely increase the supply of currency, and any would-be purchaser of goods or payor of debts or projector of an enterprise could have the time use of purchasing power gratis; no limit would exist to the rise in prices which must attend this increase in the circulating medium.

What are these limitations? (1) Each bank must conform the volume of its lending, and therewith its issue of circulating credit, to the fundamental requirement that it be always able to make good its agreement to discharge its deposit liabilities on demand. To maintain reserves involves expense. Especially may it be expensive if they have been allowed to get low; securities may have to be marketed at a sacrifice, or good customers pressed for payment at inconvenient times. In periods of general pressure or panic, other banks are not likely to be in a position to lend their own reserve funds or to consent to create deposit credit in aid of still other suffering banks. Not rarely the Bank of England, in the attempt to attract reserve funds, advances bank notes or deposit credit to importers of gold, without imposing the customary interest charge for the covering of the delays of the mint. In at least one case, in 1890, it borrowed reserves from the Bank of France. In 1907 the United States Treasury made especially large money deposits with the national banks of New York to help eke out the needed reserves. Meantime the interior banks were compelled to pay to exporting merchants generous premiums for exchange bills upon Europe, through which, despite the high interest rates ruling in European markets, these banks were able to import 107 millions of gold for their own reserve requirements. In fact, the banking business involves the hazard not merely that some of the debtors of the bank may become insolvent, but also the general and overhead hazard attaching to its underwriting service that it may itself in time of stress become unable to meet its obligations. Its liabilities must not be allowed to get seriously out of ratio to its cash resources.

The Protection of Reserves.—In point of fact also the efforts of the various different banks to maintain each its own reserve place a limit on the extent to which any one bank can extend its activity in the expansion of loans and of the derivative liabilities. Just as a relatively liberal granting of credit by one bank must tend to transfer its reserves to other banks, so a relatively great extension of credit in one center or in one country must tend to transfer the reserves, e. g., gold, to other centers or countries. Even were it true that a local credit expansion has no effect upon local prices and thereby upon the currents of trade, some transfers of reserves would still take place, and would impose a policy of restriction in credit accommodations.... The influence is actually exerted by both methods.
