I have divided credit into three branches, private, mercantile, and public. This distribution will be of use on many occasions, and shall be followed as far as it will go, consistently with perspicuity: but as I have often observed of subjects of a complex nature, they cannot be brought under the influence of a few general principles, without running into the modern vice of forming systems, by wire-drawing many relations in order to make them answer.
The great operations of domestic circulation are better discovered by an examination of the principles upon which we find banking established, than by any other method I can contrive. It has been by inquiry into the nature of those banks which are the most remarkable in Europe, that I have gathered the little knowledge I have of the theory of circulation. This induces me to think that the best way of communicating my thoughts on that subject, is to lay down the result of my inquiries relative to the very object of them.
After comparing the operations of different banks in promoting circulation, I find I can divide them, as to their policy, into two general classes, viz. those which issue notes payable in coin to bearer; and those which only transfer the credit written down in their books from one person to another.
Those which issue notes, I call banks of circulation; those which transfer their credit, I call banks of deposit.
Both indeed may be called banks of circulation, because by their means circulation is facilitated; but as different terms serve to distinguish ideas different in themselves, those I here employ, will answer the purpose as well as any others, when once they are defined; and circulation undoubtedly reaps far greater advantages from banks which issue notes transferable every where, than from banks which only transfer their credit on the very spot where the books are kept.
I shall, according to this distribution, first explain the principles upon which the banks of circulation are constituted and conducted, before I treat of the other.
This will lead me to avail myself of the division I have made of credit, into private, mercantile, and public: because, according to the purposes for which a bank is established, the ground of confidence, that is, the credit of the bank, is settled upon one or other of them.
In countries where trade and industry are in their infancy, credit must be little known; and they who have solid property, find the greatest difficulty in turning it into money, without which industry cannot be carried on, as we have abundantly explained in the 26th chapter of the second book; and consequently the whole plan of improvement is disappointed.
Under such circumstances, it is proper to establish a bank upon the principles of private credit. This bank must issue notes upon land and other securities, and the profits of it must arise from the permanent interest drawn for the money lent.
Of this nature are the banks of Scotland. To them the improvement of that country is entirely owing; and until they are generally established in other countries of Europe, where trade and industry are little known, it will be very difficult to set those great engines to work.
