Bank-credit is the debt of responsible institutions, payable on demand in money. It may take the form of notes, or of the right to draw checks. Long evolution has begot a system of legal relationships, and of banking technique which makes these promises easily performed. The same process of development has led to social reactions toward banks and bankers which give them enormous prestige. Legal regulation, in the case of many banks, requiring adequate capital, and, in this country, requiring minimum cash reserves, have added to that prestige. The promise of the bank is commonly so liquid and saleable that the banks are not called upon to fulfill it by the actual payment of money—the promise alone is an object of value which is perfectly saleable, which runs in terms of money, and which functions as a perfect substitute for money in almost every use except for very small retail transactions. Even there, it is very much used.
Among the features of banking technique to which we must give especial attention are the following: (1) the banker has substantial resources of his own, his "capital," which constitutes the "margin" of protection which he offers to those who give him valuable things in return for his promises to pay money on demand; (2) the banker exchanges his promises to pay on demand, as far as possible, for those things which have a high degree of "liquidity," i. e., for those things which he can quickly dispose of for cash, or for the promises of other bankers which are the equivalent of cash. Farm mortgages are not good assets for a banker to hold in large amount. They are long-term obligations, with a very limited market, and they will not help him in emergencies to meet his obligations to pay on demand. Agricultural loans, and other mortgage loans are made in considerable volume by our State banks and trust companies. All classes of commercial banks make many non-liquid loans, as we shall later see. But all of them get as high a proportion of liquid loans as they can. Bills of exchange, running ten, thirty, sixty or ninety days, growing out of commercial transactions which automatically terminate themselves in the payment of cash or the promises of other bankers, constitute admirable assets. In return for these, the banker may give his promises freely. This is especially true where there is, in the banking practice, a wide "rediscount market," in which he can sell these bills before maturity if he wishes to get even more liquid assets. Promissory notes, for short periods, thirty, sixty, or ninety days, growing again out of commercial transactions, which, like those for which the bills of exchange were drawn, automatically bring in cash or the promises of other banks, are in many respects like the bills of exchange, even though the rediscount market for such notes has not been so highly developed as the market for bills of exchange in Europe. Whether such notes are as available for rediscount as bills of exchange is a question of technical banking which we need not here discuss in detail, though I venture the opinion that bills of exchange are superior decidedly for this purpose, especially "documentary" bills. The element of personal credit is commonly larger in the promissory note, and that limits the market. Banking organization, and particularly our new Federal Reserve System, may greatly reduce the disadvantages of the promissory note from this angle, but it seems not unlikely that the bill of exchange may be a factor of increasing importance in our internal banking arrangements. The general test, however, of what is available for a banker's assets depends on varying conditions, and is not to be answered by a simple formula. A bank in a rural region which loads up heavily with the safest local bonds is little better off than with farm mortgages. For neither is there a quick market in an emergency. A city bank, near the stock exchange, may very safely buy in large amounts highly saleable as a profitable substitute for part of its cash reserve. Even country banks may, and do, safely own such bonds. Short loans on stock and bond security, constitute the most important single type of bank-loan in the United States, as we shall later see. (3) The third feature of banking technique to which attention must be given is the reserve policy. The banker must keep some actual money on hand (how much we have in part considered in Part II, and shall again discuss).
I shall give attention to these points in what follows. The first point needs little discussion. Large "capital" for a bank gives prestige and security. Some capital is a sine qua non for a bank which expects its notes or deposit currency to have general acceptability.
It will be well to consider further the circumstances determining the form which a bank's assets shall take. Though commercial banks own enormous quantities of high grade bonds, it is rare for commercial banks in America to buy stocks of corporations.[515] They will often lend to owners of such stocks with the stocks as collateral, up to a high percentage of the value of the stocks, but they will rarely trade their demand obligations for the stocks directly. In general, a bank wishes to have its assets in the form of obligations of other people, expressed in terms of dollars, and having a definite term to run (or callable on demand).
One reason for this is a bookkeeping reason. "Par value" of stocks has little meaning any more. Market-prices of stocks, even the best stocks, are not absolutely fixed. They fluctuate, even though within narrow limits. This fact presents complications to the bookkeeper! Of course, the bank's buildings and fixtures, listed among its assets, fluctuate also, in value, and in the price that could be obtained on a given day, but the bookkeeper can abstract from that, since the bank has no intention of selling its buildings and fixtures. The notes and bills held in the bank's portfolios also in fact fluctuate in value, and in the price at which they might be sold on a given day, but they are expressed in terms of dollars, and the bookkeeper commonly has no need to look beyond the figures written on them. At irregular intervals, a small percentage of them may be marked off the books as "bad," but usually the minor fluctuations are abstracted from. The bank does not like to have assets whose published prices fluctuate. But this is, I suppose, not the main objection which banks have to stocks as assets since it does not prevent their buying bonds. I abstract from the legal restrictions that prevent many banks from buying stocks. The fundamental reason is to be found elsewhere. The point is to be found here: the transaction whereby property rights in roadbed, rolling stock, etc., were collected into property rights in a going, organic whole increased the saleability of all these rights; the further subdivision of these rights into many thousands of equal parts enormously increased the saleability of these rights, especially when coupled with listing in an organized market; the further transaction, by which a preferential claim upon these subdivisions of rights is embodied in a collateral note still further increases the saleability of the value of these rights. The whole of the value embodied in a share of stock has not the certainty and saleability which a banker wishes for his assets. It might not be possible to market the stock on a given day without loss. But a collateral note, embodying 80% of that value, with provision for additional collateral in case the margin is reduced, is highly liquid and the banker has no doubt that, with watchfulness, he can always realize the full face value of such a note. It becomes saleable enough for his purposes. The transaction by which this note is exchanged for the banker's demand obligation gives the drawer of the collateral note a perfectly saleable form of value with an almost universal market, which he can convert without loss into practically anything that money can buy. We have here a series, a scale, saleability of rights growing steadily greater, through a series of transformations and exchanges, till at last the virtually perfect saleability is reached. Again we are reminded of Menger's analysis[516] of the methods of primitive barter, whereby the man who possesses a good of low saleability, through successive exchanges, gradually gets goods of higher and higher saleability, until he finally reaches his goal. Bank-credit, this most highly saleable of all forms of rights except the rights to actual money in hand, and in general not inferior to money, cannot usually be had by direct offer to the bank of crude property rights. These must be refined and distilled, till a central core of highly saleable value emerges, and then they may enter the bank's assets in return for bank-credit. The best bonds likewise offer such a central core of highly saleable value.
A further point is to be noticed about this scale of saleabilities. At each stage of the exchanges of less saleable for more saleable rights, the holder of the less saleable rights must make concessions to the holder of the more saleable rights. And the degree of his concession is, in general, correlated with the lack of saleability of what he offers. Commonly this takes the form of giving up a right which has a higher yield for one which has a lower yield. Or, viewed more fundamentally, from the angle of the capitalization theory, income-bearers of low saleability are capitalized at a higher discount rate than income-bearers of higher saleability, with the same yield. Farm lands may be capitalized on a 10% basis. (There will be great differences between regions in this, depending in considerable measure, often, on the activity of farm sales. I would refer here to the facts mentioned in my chapter on "The Quantity Theory and International Gold Movements," contrasting Cass Co., Iowa, with Yazoo Co., Mississippi. Of course, the risks of agriculture count heavily, also, and the prestige of owning land as compared with other forms of property.) The farmer's mortgage note may bear 7%. A merchant who holds that note may use it as collateral, with a margin, backing his own note, and get accommodation for three months at 6%. The bank may rediscount the note of the merchant, giving it its own endorsement, on a 4½% basis. The coal mine owned by a small company may yield 12%; sold to a large iron company, which combines mining and smelting and manufacturing, that mine may be represented by 7% stock; a collateral loan, for sixty days, based on 80% of the value of the stock may be had for 4%; the demand liability of the bank given in exchange for the collateral note will either yield nothing at all, or else yield a low per cent, one, one and a half, or 2%, on large checking accounts. If the collateral note be a call note, the rate will be lower, in general, than on a time note. I here refer to what was said in the chapter on the functions of money with reference to the relation of short loans, especially call loans, to the "bearer of options" function of money. Part of the yields of these loans is in the bearing of options. This function grows out of the uncertainties of a dynamic market. It would disappear if uncertainties, "friction," and dangers disappeared.
The importance of liquidity and saleability in the assets of a banker needs little discussion. It has been reiterated by virtually every writer on the subject. Its connection with the need for meeting demand obligations is obvious. The point that I would here emphasize is, however, that this, too, grows out of dynamic changes, uncertainties, etc. An economic life in "normal equilibrium," in static balance, with all things going smoothly, in anticipated ways, could dispense in large measure, or wholly, with such liquidity. Obligations which matured at the time that the holders of the obligations had maturing obligations, would serve their purpose perfectly. Again I would emphasize the fact that the theory of money and bank-credit is essentially a dynamic theory, and that the notion of "normal equilibrium" which underlies the quantity theory has no bearing whatever on these fundamental matters.
The market where fluid bank-credit is exchanged for less fluid rights has been given the name, "the money market." The prices fixed in this market are "money-rates," figured as percentages on the amounts of bank-credit exchanged for the less fluid rights. It is, of course, strictly speaking, not a money market. Money, as the term has been used in this book, has been taken to mean gold coin, subsidiary coin, government paper, and for the United States, bank-notes. In a country where much bank-credit is elastic bank-notes, it is better to distinguish money from bank-notes. The term, money, is not one easily defined in a logical manner. A good logical definition should seize on some essential characteristic of the object defined, should include all the objects of that class, and should exclude all others. We can meet the tests of inclusiveness and exclusiveness in a definition of money, but we can hardly meet the first test. The differences between gold money, for example, and gold bullion are less than the differences between gold money and government paper. The differences between bank-notes and bank-deposits are less than the differences between bank-notes and government paper, or bank-notes and gold. The term, money, covers a group of more or less miscellaneous things, concerning all of which few general laws are possible. Gold, or other standard money, in particular, may obey different laws from other forms of money. I have been careful, in the foregoing, to avoid the danger of letting the argument rest on any ambiguity in the meaning of the term, however, and for the present shall not attempt further definition. For the present, we shall use the term, "money market," in its familiar sense, as meaning that market in which bank-credit is exchanged for less fluid rights. An organized money market commonly appears only in larger cities. In smaller places, relationships between banks and customers are much more personal, and indeed, even in larger cities, regular business houses have particularly intimate relations with special banks. A fluid, impersonal market, to which men may repair without reference to anything but the marketability of the collateral they have to offer, is a distinctively metropolitan affair. Only large dealers commonly have relations with more than one or two banks. Larger houses in the big cities often do sell their "commercial paper" through brokers, and some of the big New York mercantile houses have had their paper scattered a good deal throughout the country. The lack of protection which houses which sought such credit faced during the Panic of 1907 tended to check the practice in some measure, but it has revived, and even increased.[517] In the matter of a wide market for commercial paper, however, an impersonal market, with great fluidity, we are well behind not only England, but also Continental Europe. The London acceptance house has especially contributed to an impersonal market. The American money market is par excellence a New York market, and the primary type of paper discounted in the American money market is stock exchange paper, and foreign bills of exchange. For commercial paper, however, there are innumerable more personal, more restricted, markets, and commercial paper constitutes a very considerable part of banking assets, though much less than is often supposed. But this we shall discuss in the next chapter.
