The consequence of a bank upon mortgage, is to fill the nation with paper money, and to reduce the quantity of coin to the lowest sum possible. For the truth of this proposition, I appeal to the experience of Scotland, and of Rome, where banks upon mortgage, and moveable pledges, are found established. From these facts, and from the principles of their constitution, which is to melt down property into money, it follows, that when the credit of such money is well established, the coin, which is the money of the world, will be employed in trading with the world, and the paper, which is the money of the society, will be employed in trading with the society.
The consequence of this, is, that when the balance of trade runs against a country where banks upon mortgage are established, the coin first goes out; and when, by borrowing, it can be brought back, the interest paid for the coin borrowed, adds an additional balance against the country, until the whole revenue of it becomes the property of other nations. From this we may conclude, that the establishment of such banks is as dangerous a weapon in the hands of an idle nation, as an extensive credit is to the family of a young spendthrift.
But let us consider the consequences of such banks to an industrious people, who preserve, upon the average of their trade, a favourable balance with other nations.
The coin, then, goes out to return, and serves as a check upon the course of exchange. I here suppose proper regulations in the mint, and an entire liberty to export coin. Permitting the exportation of coin where you have a mint, for paper to supply its place, and a favourable balance on your trade to bring it back, is like establishing two shops for the course of exchange. If the exchanger will not serve trade at the price of transportation and insurance, the coin will do it for him.
In such a country, a bank, properly established, will find great profit upon the interest of their notes, notwithstanding of the obligation to provide, at all times, the quantity of coin necessary for circulation. All the great objects of trade will then be fulfilled; the rest must be left to the operation of political causes.
If the balance of the trade of such a country should have the effect of bringing in an addition of coin, which, because of the paper, would become unnecessary for circulation; this coin, or the value of it, will either be added to their stock in trade, or will be lent to other nations. This is the case of the Swiss: they are an industrious and a frugal people; they receive annually from their trade, and from the service of their citizens in many countries in Europe, a constant addition to their wealth, more than their trade demands, which they lend to their neighbours; by these means they increase the revenue of the society; and this increase has effects almost similar to an extension of their territory; because it is a means of increasing their population beyond the proportion of the natural produce of their lands; and the food they import from Germany and other countries, is paid with the money which arises from the interest of what they have lent abroad. All these operations are the consequences of credit and circulation.
In a country where a mercantile bank is established, the melting down of property is greatly circumscribed; and consequently coin becomes more necessary.
We have often said, that a circulating value (money) must constantly bear a proportion to alienation. Circumstances will determine what proportion of coin and what proportion of paper will be necessary for carrying it on. These circumstances, under banks of circulation upon mortgage, multiply paper so much that little coin is required.
Let us now examine how far the paper of a mercantile bank, like that of England, tends to supply the demand of circulation.
Were no bank established at London, all bills would be paid, or discounted in coin.
