(1.) The money is safe, as the banker provides strong rooms, locked and guarded at night.
(2.) It is easy to pay the money away by means of cheques or written orders entitling the persons named therein to demand a specified sum of money from the banker.
(3.) The banker usually allows some interest for the money in his care.
Bankers receive deposits on various terms; sometimes the depositor engages to give seven days' notice before withdrawing his deposit; in other cases the money is lent to the banker for one, three, or six months certain, and the longer the time for which it is lent the better the rate of interest the banker can usually give. But a great deal of money is deposited #on current account#, that is, the customer puts his money into the bank, and draws it out just when he likes, without notice. In this case the banker gives very little interest, or none at all, because he has to keep much of the money ready for his customers, not knowing when it will be wanted.
Nevertheless, while some depositors are drawing their money out, others will be putting more in, and it is exceedingly unlikely that all the thousands of customers of a large bank will want their deposits at the same time. Thus it happens that the banker, in addition to his own capital, has a large stock of money always on hand, and he makes profit by lending out this money to other customers, who need credit.
There are various ways in which a banker arranges his loans; sometimes he lends upon the mortgage of goods, houses, and other property, or of shares in railways and government funds, in the way described; but this is not a proper way for a banker to employ much of his funds, because he may not be able to get back such loans rapidly enough when he needs them. One of the simplest ways of lending money is to allow customers to overdraw their accounts, that is, to draw more money out of the bank than they have put in. But a banker naturally takes care not to allow overdrafts unless he has great confidence in his customer, or has received a guarantee of repayment from him or his friends.
#86. Discount of Bills.# The most common and proper way in which a banker gives credit and employs his funds is in the discount of bills, that is, in advancing money in exchange for a definite promise to pay it back at a stated time. Suppose that John Smith has sold a thousand pounds worth of cotton goods to Thomas Jones, a shopkeeper; several months will pass perhaps before Jones can sell the goods over the counter, and if he has not much capital, he agrees that John Smith shall give credit for the thousand pounds but in the mean time draw a bill upon Jones. This bill would very likely be somewhat in this form--
