The development of bank loans on stock exchange collateral is a remarkable feature of the three or four decades preceding 1909. The following figures, of national bank loans in New York City,[531] illustrate the tendency:

The tendency is not peculiar to America, however. The following table gives a classification of the loans and discounts of all the great European banks[533] in selected years from 1875 to 1903:

We conclude, therefore, that the great bulk of banking credit in the United States, even of "commercial banks," is not commercial credit. Much of it, in the smaller places, especially, represents in fact, whatever the form, long time advances to agriculture and industry. Most of it, in the great cities, and to a large extent in even the smaller places, represents advances to the permanent financing of corporate industry. Excluding real estate loans, more than half of bank-credit represents either ownership of bonds (with some stocks) or else advances on stocks and bonds. Another important part of bank-credit, which I shall not even attempt to measure, is employed in financing commodity speculation.

It is worth while to compare our figures concerning bank loans with Kinley's figures, which we have previously considered, for deposits made on March 16 of 1909, the year we have chosen for the bank loans figures. It is important to remember that "deposits," as used by Kinley in this investigation, does not mean what the term means in a bank balance sheet. Kinley's figures relate to the actual items deposited on the day in question, and not to the net balance after deposits and withdrawals have been compared when the bank has closed for the day. A large deposit in the balance sheet sense might show no "deposits" in Kinley's sense, in a given day; while enormous "deposits" in Kinley's sense might be so offset by incoming checks that virtually nothing is left on the balance sheet at the end of the day, for a given depositor. Kinley's figures thus give us a means of getting at the degree of activity of different classes of deposits in the balance sheet sense, and so, indirectly, of different classes of loans.

Loans and deposits (in the balance sheet sense) are, as we know, closely correlated. This is true for banks in the aggregate, and for banks individually at a moment of time. It is not generally true of a given individual deposit account at a moment of time, but through a period of time, for business deposits, it tends to be true that the items deposited offset the amounts borrowed.[534] If the items deposited are numerous, if the depositor has an "active" deposit account, receiving a large flow of banking funds, as compared with his net deposit balances, we may infer that his loans are also active, that he pays off loans frequently, that his paper, in the assets of the bank, is "liquid."

I need not give the details of Kinley's figures again, as they have been elaborately analyzed in connection with the estimate of the "volume of trade."[535] The figures show that retail and wholesale deposits between them make up about 25% of the total deposits. This would serve to show that "commercial paper," which we have allowed to be about 24.8 of total loans, is slightly more active (and hence "liquid") than the average of loans.[536] It will also suggest, however, that our figure for "commercial paper," truly liquid, is too high, since we should expect this kind of paper to be more active than the average—unless, indeed, stock exchange collateral loans are so exceedingly active as to make a tremendously high average. I refrain from trying to get a definite answer on this point, since there are many indeterminate elements: among others, uncertainty as to the extent to which wholesale deposits and retail deposits include all commercial deposits, and uncertainty as to the extent to which they exclude manufacturer's deposits. The great bulk of Kinley's deposits, however, fall into the "all other" class, and the great bulk of the "all other deposits" are located in the great financial and speculative centres, particularly New York. We have concluded that they represent chiefly (a) transactions in securities; (b) other speculation; (c) loan and other financial transactions, particularly the shifting of call loans on stock exchange collateral. It is, then, the deposits of those connected with the great financial and speculative markets, particularly the stock market, whose deposits are most active, and whose loans are most liquid. Stock market collateral loans thus constitute the most perfectly satisfactory sort of bank loan, from the standpoint of liquidity. Though such loans do not make up the bulk of bank loans (we have concluded that they constitute 30.6% of the loans of State and national banks and trust companies in 1909), they do account for the bulk of banking activity, and supply the greatest part of the liquidity of total bank loans.

When we consider further the item of securities (chiefly bonds) in banking assets, we find another highly important source of liquidity. The sales of bonds in the great banking centres are enormous. The figures of bond sales on the exchanges do not begin to tell the story. One big bank in New York in 1911 sold more than half as many bonds as were sold in that year on the floor of the Stock Exchange.[537] It has been frequently stated that ten bonds, of those listed on the Exchange are sold over the counter for one on the floor. This is truer of Boston than New York. The "outside market" for unlisted bonds is a very important matter. Dealings among banks in these items and in foreign exchange are exceedingly important. This is especially true of the business of the great private bankers, as Morgan, Kuhn-Loeb and others. Much of this does not appear in Kinley's figures, since neither the deposits of the great private banks in other banks, nor the deposits made in the private banks themselves (so far as New York City is concerned) figure in his totals.[538] Had they been included, the percentage of the "all other deposits" would have grown, and we should have had still more impressive evidence of the fact that modern banking in the United States is largely bound up with the security market, and that modern bank-credit gets its liquidity chiefly from that source.

The story is even more impressively told by the figures for bank clearings, which include the transactions between banks, and the transactions of the private bankers. In New York, in 1909, total clearings for the year were 104 billions, as against 62 billions for the whole country outside New York.[539] That bank clearings are closely correlated with stock exchange transactions, has been demonstrated fully by N. J. Silberling, who has shown the following correlations: New York Stock Exchange share sales with New York clearings, r = .718; total clearings for the country with New York share sales, r = .607; total clearings for the country with railway gross receipts (as representative of ordinary trade), r = .356.[540] The active deposits and the liquid loans are chiefly connected with activities in finance and speculation.
