When it is said that a bank has $10,000,000, $50,000,000 or $100,000,000 or $200,000,000 of deposits, they are not deposits in cash at all; they are almost entirely pure credit, and are exactly equivalent to just as many "Bank Notes." They are nothing but an enormous superstructure of _Credit_ built up on a comparatively small basis of reserves exactly like the note circulation. These figures do not show the quantity of cash at the command of the bank that can be traded with; but they show the quantity of business the bank has done, and the debts or liabilities it has created. These deposits, then, which so many think are cash, are in fact nothing but the credits the banks have created in exchange for the cash and notes which figure on the other side of the balance sheet as assets or resources. This play of bank credit has been graphically described by Joseph T. Talbot, the Vice-President of one of our largest National Banks; he says: "A customer holding a bank note may present it for deposit and credit, instead of demanding redemption in cash. In this case, there is a conversion from the circulating form of credit, payable to bearer, back to a 'Book Credit,' payable to order, as was ordinarily the case. Thus it will be seen that all these forms of 'Bank Credits' are interchangeable, one for another, at the pleasure of the holder of the credit. The difference between these several forms of credit involves no changes whatever in the bank's liabilities. They amount to about the same difference which exists, let us say, between a coupon bond and a registered bond. The one is payable to bearer, the other is not. At one time a bank note may best serve a customer's needs; at another time he might prefer a deposit in the bank; or again he might prefer 'exchange.' All these interchangeable uses of credit actually and continuously take place. It will now be clear that a circulating 'Bank Note' in the hands of the public does not differ essentially from a 'Deposit Credit' on the bank's books. "If one of your local bankers were asked how much he allowed his bank to issue in cashier's checks, he would tell you that he issued whatever sums his customers wanted; either against their balances, or against new loans. He would tell you the same in respect of the amount of exchange he issued; his sole rule and guide being the amount of such credit which his customers require, and which he is in position to lend afresh, and to maintain against, or to redeem in cash, if demanded. If asked how long these obligations were allowed to remain outstanding, he would tell you that he had no control whatever over the period of their circulation; that these obligations stood out just as long as the holders wanted to use them in that form, and no longer; that his only concern was in being prepared to redeem the obligations on demand in cash.
