The Wealth of Nations

it would have been, had he not been obliged to keep such a sum unemployed. Let us suppose that he generally disposes of his whole stock upon hand, or of goods to the value of his whole stock upon hand, once in the year. By being obliged to keep so great a sum unemployed, he must sell in a year five hundred pounds worth less goods than he might otherwise have done. His annual profits must be less by all that he could have made by the sale of five hundred pounds worth more goods; and the number of people employed in preparing his goods for the market, must be less by all those that five hundred pounds more stock could have employed. The merchant in Edinburgh, on the other hand, keeps no money unemployed for answering such occasional demands. When they actually come upon him, he satisfies them from his cash account with the bank, and gradually replaces the sum borrowed with the money or paper which comes in from the occasional sales of his goods. With the same stock, therefore, he can, without imprudence, have at all times in his warehouse a larger quantity of goods than the London merchant; and can thereby both make a greater profit himself, and give constant employment to a greater number of industrious people who prepare those goods for the market. Hence the great benefit which the country has derived from this trade.

The facility of discounting bills of exchange, it may be thought indeed, gives the English merchants a conveniency equivalent to the cash accounts of the Scotch merchants. But the Scotch merchants, it must be remembered, can discount their bills of exchange as easily as the English merchants; and have, besides, the additional conveniency of their cash accounts.

The whole paper money of every kind which can easily circulate in any country never can exceed the value of the gold and silver, of which it supplies the place, or which (the commerce being supposed the same) would circulate there, if there was no paper money. If twenty shilling notes, for example, are the lowest paper money current in Scotland, the whole of that currency which can easily circulate there cannot exceed the sum of gold and silver which would be necessary for transacting the annual exchanges of twenty shillings value and upwards usually transacted within that country. Should the circulating paper at any time exceed that sum, as the excess could neither be sent abroad nor be employed in the circulation of the country, it must immediately return upon the banks to be exchanged for gold and silver. Many people would immediately perceive that they had more of this paper than was necessary for transacting their business at home, and as they could not send it abroad, they would immediately demand payment of it from the banks. When this superfluous paper was converted into gold and silver, they could easily find a use for it by sending it abroad; but they could find none while it remained in the shape of paper. There would immediately, therefore, be a run upon the banks to the whole extent of this superfluous paper, and, if they showed any difficulty or backwardness in payment, to a much greater extent; the alarm, which this would occasion, necessarily increasing the run.

Over and above the expenses which are common to every branch of trade; such as the expense of house-rent, the wages of servants, clerks, accountants, etc.; the expenses peculiar to a bank consist chiefly in two articles: First, in the expense of keeping at all times in its coffers, for answering the occasional demands of the holders of its notes, a large sum of money, of which it loses the interest: And, secondly, in the expense of replenishing those coffers as fast as they are emptied by answering such occasional demands.

A banking company, which issues more paper than can be employed in the circulation of the country, and of which the excess is continually returning upon them for payment, ought to increase the quantity of gold and silver, which they keep at all times in their coffers, not only in proportion to this excessive increase of their circulation, but in a much greater proportion; their notes returning upon them much faster than in proportion to the excess of their quantity. Such a company, therefore, ought to increase the first article of their expense, not only in proportion to this forced increase of their business, but in a much greater proportion.

The coffers of such a company too, though they ought to be filled much fuller, yet must empty themselves much faster than if their business was confined within more reasonable bounds, and must require, not only a more violent, but a more constant and uninterrupted exertion of expense in order to replenish them. The coin too, which is thus continually drawn in such large quantities from their coffers, cannot be employed in the circulation of the country. It comes in place of a paper which is over and above what can be employed in that circulation, and is therefore over and above what can be employed in it too. But as that coin will not be allowed to lie idle, it must, in one shape or another, be sent abroad, in order to find that profitable employment which it cannot find at home; and this continual exportation of gold and silver, by enhancing the difficulty, must necessarily enhance still further the expense of the bank, in finding new gold and silver in order to replenish those coffers, which empty themselves so very rapidly. Such a company, therefore, must, in proportion to this forced increase of their business, increase the second article of their expense still more than the first.

Let us suppose that all the paper of a particular bank, which the circulation of the country can easily absorb and employ, amounts exactly to forty thousand pounds; and that for answering occasional demands, this bank is obliged to keep
