Into these we shall not inquire: the principle on which they depend appears sufficiently plain, and this is the principal object of our attention.
I proceed now to consider how far those reciprocal profits and losses, between merchants in the same country, affect the trade of it in general.
When the balance is favourable, we have said that the exporters lose the exchange, and the importers gain it; and both being citizens, the country would not be concerned in their relative interests, were it not that these interests are connected with that of the country, which reaps great benefit from the trade of those who deal in exportations, and loss from the other.
If, therefore, exchange is found to hurt exportation, when the balance is favourable, in this respect the country has an interest in bringing it as low as possible. But as it may be said that since the return of an unfavourable balance hurts in its turn the interests of importation, and favours the other, exchange thereby operates a national compensation; it will not be improper, in this place, to throw out one reflection more, in order to destroy the strength of that argument.
Were this proposition admitted, as I am afraid it cannot, from what we have already said, it affords no argument against doing what can be done, to render exchange as little hurtful as possible to exportation, during the favourable balance. But as to the question itself, of national compensation, I cannot allow that even exporters and importers are thereby brought on a level in point of trade: for this reason, that the exchange affecting the exporters, in proportion as it augments, discourages manufacturers, who must have regular, and even growing profits, according to the increase of demand. These the merchant exporter cannot afford; because he cannot draw back from his foreign correspondents, any advance upon manufactures at home, arising from domestic circumstances. But when the merchant importer is affected by the exchange against him; this additional expence he can draw back; because he sells to those who are affected by all domestic circumstances.
Let us therefore determine, that it is the interest of a state to disregard that compensation which is given to exportation by a wrong balance, which does so much harm; and to avoid the discouragement given to it by a right balance, which does so much good. The only way to compass those ends, is to keep exchange as near to par as possible.
Could reciprocal debts be always exchanged at par, and could the expence of bringing home, and sending a balance abroad, be defrayed by the state, I think it would prove a great advantage to the trade of a nation. I do not pretend to say that, as matters stand, the thing is practicable; but as it is a question which relates to my subject, and seems both curious and interesting, I shall here examine it.
At first sight, this idea will appear chimerical; and some readers may despise it too much, to be at the trouble to read what may be said for it. I shall therefore set out by informing them that the scheme has been tried, in a great kingdom in Europe, under a great minister; I say it was attempted in France, in the year 1726, under the administration of Cardinal Fleuri, and produced its effect; although it was soon given up, from a circumstance which, I think, never can occur in Great Britain.
After the last general coinage in France, 1726, exchange became so unfavourable to that kingdom, that there was a general outcry. The Cardinal, to put a stop to the clamour, and set trade to rights, as he thought, ordered Samuel Bernard, at that time a man of great credit, to give bills on Holland at par, to all the merchants. To enable him to place funds in Amsterdam, for the payment of his bills, the Cardinal supplied this exchanger with sufficient quantities of the old coin, then cried down, and paid for the exportation of it to Holland.
Upon this exchange on Holland came to par; and all exchangers at Paris looked on the operation with amazement. The minister, however, in a short time discovered, that by this he was undoing with one hand, what he wanted to establish with the other. He therefore stopped in his career, after having paid, perhaps, ten times the balance due to Holland.
