This six and a half billions in checks saved on account of sales of stocks is no small matter, absolutely. But this, though measuring the extent of undercounted _sales_, by no means measures the services of the Clearing House to the Stock Exchange. Not merely stocks _sold_ have to be cleared. Stocks _borrowed_ are also cleared. Borrowing of stocks is not _trade_, but borrowing of stocks requires the passage of money and checks. When stocks are borrowed, money is _loaned_. A bear sells short. He has to deliver next day. He accomplishes this by having his broker "borrow" the stock he needs from a broker representing a bull, who is long on the stocks, and who needs money to "carry" them. The bull, who lends the stock, receives dividends from the bear, as they accrue, and pays the bear interest on the money lent. An enormous lot of this takes place. Moreover, to some extent, these transactions are increased artificially, in order that the broker may make his "clearing sheet" misleading, and avoid revealing his position with reference to the market.[435] Loans of stock and sales of stock appear alike in the transactions of the Clearing House. Moreover, apart from the necessities of the bears for stocks to deliver, we have the necessities of the bulls for money to carry their stocks. If a broker who has borrowed largely from the banks finds his customers turning to the bear side of the market, he has an excess of funds. He may repay his loans, but they may be, in part, time loans, and in any case, he may find it just as well, if he can make a small fraction of 1% in interest, to lend to another broker, among whose customers the bulls are increasing. A vast deal of money is thus transferred, on collateral security, by means of "loaning stocks." Brokers prefer to borrow money from one another in this manner, since no margins are required, in general, whereas banks would require margins. These various reasons make a vast deal of "borrowing and carrying" transactions, and a regular place is set aside for them on the Floor--Post 4, commonly called the "Money Post." At this post, also, the banks, through brokers, lend on call, and the published call rates are established there. Of this, however, we shall have more to say later.
