If the compensation be considered only in relation to the merchants importers and exporters, there, indeed, I agree, that their profit and loss upon the exchange is most exactly balanced; because what the one party gains the other loses; and the country loses the balance only, as has been said.
The reciprocal debts thus transacted by bills of exchange, we see that no profit can be made, nor loss incurred, either to London, or Paris, by that operation.
The profit to Frenchmen is compensated by the loss to Frenchmen; the same may be said of the English merchants: but the balance due after those operations are over, and the more remote consequences of high exchange, affect the relative interest of the two nations.
This balance is generally sent by the country-debtor, either to the country-creditor, or to their order in a third country, to which they are indebted.
The transportation and insurance of this balance is an expence to those who owe it, and the profit, if any there be on that operation, naturally falls to exchangers of the same nation, who conduct it. So whether exchange be paid upon bills drawn, or expence be incurred in the transportation of balances, no profit can accrue upon that to the nation-creditor, to the detriment of the debtor: it must, therefore, do hurt to both, relatively to nations where, upon the average of trade, exchange is lower.
I come now to the method of transporting balances in the metals.
We have seen how the creditors of the nation-debtor pay exchange upon the sale of their bills on Paris, which owes the balance. If by the operations of exchangers, this exchange should rise, to their detriment, higher than the expence, trouble, and insurance, of bringing the balance from Paris, then they will appoint some factor at Paris, to whose order they will draw bills upon their debtors in that city; and as what the Paris-debtors owe to London is stated in pounds sterling, the London-creditors will value the pound sterling, according to the rate of exchange, in their favour; and in their bills upon their Paris-debtor, they will convert the sum into livres, including the exchange.
By this operation, we see how the transportation of the balance may become the business of the creditors to the nation-debtor: which is a combination we have not as yet attended to: a few words will explain it.
When the creditors of the nation-debtor sell their bills, they must pay the exchange, as has been said. When they draw bills to the order of a friend in the place where the balance is owing, they superadd the exchange. This their debtors pay: but then they themselves must be at the trouble and expence of bringing home the money.
It is from this alternative which both parties have of either sending what they owe to their creditors in bullion, or of allowing them to draw for it at the additional expence of paying the exchange, that a check upon the extravagant profit of exchangers arises: and from this combination arises all the delicate operations of drawing and remitting.
