First, though it were certain that in the case of a free trade between France and England, for example, the balance would be in favour of France, it would by no means follow that such a trade would be disadvantageous to England, or that the general balance of its whole trade would thereby be turned more against it. If the wines of France are better and cheaper than those of Portugal, or its linens than those of Germany, it would be more advantageous for Great Britain to purchase both the wine and the foreign linen which it had occasion for of France than of Portugal and Germany. Though the value of the annual importations from France would thereby be greatly augmented, the value of the whole annual importations would be diminished, in proportion as the French goods of the same quality were cheaper than those of the other two countries. This would be the case, even upon the supposition that the whole French goods imported were to be consumed in Great Britain.
But, secondly, a great part of them might be re-exported to other countries, where, being sold with profit, they might bring back a return equal in value, perhaps, to the prime cost of the whole French goods imported. What has frequently been said of the East India trade might possibly be true of the French; that though the greater part of East India goods were bought with gold and silver, the re-exportation of a part of them to other countries brought back more gold and silver to that which carried on the trade than the prime cost of the whole amounted to. One of the most important branches of the Dutch trade, at present, consists in the carriage of French goods to other European countries. Some part even of the French wine drank in Great Britain is clandestinely imported from Holland and Zealand. If there was either a free trade between France and England, or if French goods could be imported upon paying only the same duties as those of other European nations, to be drawn back upon exportation, England might have some share of a trade which is found so advantageous to Holland.
Thirdly, and lastly, there is no certain criterion by which we can determine on which side what is called the balance between any two countries lies, or which of them exports to the greatest value. National prejudice and animosity, prompted always by the private interest of particular traders, are the principles which generally direct our judgment upon all questions concerning it. There are two criterions, however, which have frequently been appealed to upon such occasions, the custom-house books and the course of exchange. The custom-house books, I think, it is now generally acknowledged, are a very uncertain criterion, on account of the inaccuracy of the valuation at which the greater part of goods are rated in them. The course of exchange is, perhaps, almost equally so.
When the exchange between two places, such as London and Paris, is at par, it is said to be a sign that the debts due from London to Paris are compensated by those due from Paris to London. On the contrary, when a premium is paid at London for a bill upon Paris, it is said to be a sign that the debts due from London to Paris are not compensated by those due from Paris to London, but that a balance in money must be sent out from the latter place; for the risk, trouble, and expense of exporting which, the premium is both demanded and given. But the ordinary state of debt and credit between those two cities must necessarily be regulated, it is said, by the ordinary course of their dealings with one another. When neither of them imports from the other to a greater amount than it exports to that other, the debts and credits of each may compensate one another. But when one of them imports from the other to a greater value than it exports to that other, the former necessarily becomes indebted to the latter in a greater sum than the latter becomes indebted to it; the debts and credits of each do not compensate one another, and money must be sent out from that place of which the debts overbalance the credits. The ordinary course of exchange, therefore, being an indication of the ordinary state of debt and credit between two places, must likewise be an indication of the ordinary course of their exports and imports, as these necessarily regulate that state.
But though the ordinary course of exchange should be allowed to be a sufficient indication of the ordinary state of debt and credit between any two places, it would not from thence follow that the balance of trade was in favour of that place which had the ordinary state of debt and credit in its favour. The ordinary state of debt and credit between any two places is not always entirely regulated by the ordinary course of their dealings with one another; but is often influenced by that of the dealings of either with many other places. If it is usual, for example, for the merchants of England to pay for the goods which they buy of Hamburg, Dantzic, Riga, etc, by bills upon Holland, the ordinary state of debt and credit between England and Holland will not be regulated entirely by the ordinary course of the dealings of those two countries with one another, but will be influenced by that of the dealings of England with those other places. England may be obliged to send out every year money to Holland, though its annual exports to that country may exceed very much the annual value of its imports from thence; and though what is called the balance of trade may be very much in favour of England.
In the way, besides, in which the par of exchange has hitherto been computed, the ordinary course of exchange can afford no sufficient indication that the ordinary state of debt and credit is in favour of that country which seems to have, or which is supposed to have, the ordinary course of exchange in its favour: or, in other words, the real exchange may be, and, in fact, often is so very different from the computed one, that from the course of the latter no certain conclusion can, upon many occasions, be drawn concerning that of the former.
When for a sum of money paid in England, containing, according to the standard of the English mint, a certain number of ounces of pure silver, you receive a bill for a sum of money to be paid in France, containing, according to the standard of the French mint, an equal number of ounces of pure silver, exchange is said to be at par between England and France. When you pay more, you are supposed to give a premium, and exchange is said to be against England and in favour of France. When you pay less, you are supposed to get a premium, and exchange is said to be against France and in favour of England.
But, first, we cannot always judge of the value of the current money of different countries by the standard of their respective mints. In some it is more, in others it is less worn, clipt, and otherwise degenerated from that standard. But the value of the current coin of every country, compared with that of any other country, is in proportion not to the quantity of pure silver which it ought to contain, but to that which it actually does contain. Before the reformation of the silver coin in King William’s time, exchange between England and Holland, computed in the usual manner according to the standard of their respective mints, was five-and-twenty per cent against England. But the value of the current coin of England, as we learn from Mr Lowndes, was at that time rather more than five-and-twenty per cent below its standard value. The real exchange, therefore, may even at that time have been in favour of England, notwithstanding the computed exchange was so much against it; a smaller number of ounces of pure silver actually paid in England may have purchased a bill for a greater number of ounces of pure silver to be paid in Holland, and the man who was supposed to give may in reality have got the premium. The French coin was, before the late reformation of the English gold coin, much less worn than the English, and was perhaps two or three per cent nearer its standard. If the computed exchange with France, therefore, was not more than two or three per cent against England, the real exchange might have been in its favour. Since the reformation of the gold coin, the exchange has been constantly in favour of England, and against France.
Secondly, in some countries, the expense of coinage is defrayed by the government; in others, it is defrayed by the private people who carry their bullion to the mint, and the government even derives some revenue from the coinage. In England, it is defrayed by the government, and if you carry a pound weight of standard silver to the mint, you get back sixty-two shillings, containing a pound weight of the like standard silver. In France, a duty of eight per cent is deducted
for the coinage, which not only defrays the expense of it, but affords a small revenue to the government. In England, as the coinage costs nothing, the current coin can never be much more valuable than the quantity of bullion which it actually contains. In France, the workmanship, as you pay for it, adds to the value in the same manner as to that of wrought plate. A sum of French money, therefore, containing a certain weight of pure silver, is more valuable than a sum of English money containing an equal weight of pure silver, and must require more bullion, or other commodities, to purchase it. Though the current coin of the two countries, therefore, were equally near the standards of their respective mints, a sum of English money could not well purchase a sum of French money containing an equal number of ounces of pure silver, nor consequently a bill upon France for such a sum. If for such a bill no more additional money was paid than what was sufficient to compensate the expense of the French coinage, the real exchange might be at par between the two countries, their debts and credits might mutually compensate one another, while the computed exchange was considerably in favour of France. If less than this was paid, the real exchange might be in favour of England, while the computed was in favour of France.
Thirdly, and lastly, in some places, as at Amsterdam, Hamburg, Venice, etc, foreign bills of exchange are paid in what they call bank money; while in others, as at London, Lisbon, Antwerp, Leghorn, etc., they are paid in the common currency of the country. What is called bank money is always of more value than the same nominal sum of common currency. A thousand guilders in the bank of Amsterdam, for example, are of more value than a thousand guilders of Amsterdam currency. The difference between them is called the agio of the bank, which, at Amsterdam, is generally about five per cent. Supposing the current money of the two countries equally near to the standard of their respective mints, and that the one pays foreign bills in this common currency, while the other pays them in bank money, it is evident that the computed exchange may be in favour of that which pays in bank money, though the real exchange should be in favour of that which pays in current money; for the same reason that the computed exchange may be in favour of that which pays in better money, or in money nearer to its own standard, though the real exchange should be in favour of that which pays in worse. The computed exchange, before the late reformation of the gold coin, was generally against London with Amsterdam, Hamburg, Venice, and, I believe, with all other places which pay in what is called bank money. It will be no means follow, however, that the real exchange was against it. Since the reformation of the gold coin, it has been in favour of London even with those places. The computed exchange has generally been in favour of London with Lisbon, Antwerp, Leghorn, and, if you except France, I believe, with most other parts of Europe that pay in common currency; and it is not improbable that the real exchange was so too.

Part II
Of the Unreasonableness of those Extraordinary Restraints upon other Principles
In the foregoing Part of this Chapter I have endeavoured to show, even upon the principles of the commercial system, how unnecessary it is to lay extraordinary restraints upon the importation of goods from those countries with which the balance of trade is supposed to be disadvantageous.
Nothing, however, can be more absurd than this whole doctrine of the balance of trade, upon which, not only these restraints, but almost all the other regulations of commerce are founded. When two places trade with one another, this doctrine supposes that, if the balance be even, neither of them either loses or gains; but if it leans in any degree to one side, that one of them loses and the other gains in proportion to its declension from the exact equilibrium. Both suppositions are false. A trade which is forced by means of bounties and monopolies may be and commonly is disadvantageous to the country in whose favour it is meant to be established, as I shall endeavour to show hereafter. But that trade which, without force or constraint, is naturally and regularly carried on between any two places is always advantageous, though not always equally so, to both.
By advantage or gain, I understand not the increase of the quantity of gold and silver, but that of the exchangeable value of the annual produce of the land and labour of the country, or the increase of the annual revenue of its inhabitants.
If the balance be even, and if the trade between the two places consist altogether in the exchange of their native commodities, they will, upon most occasions, not only both gain, but they will gain equally, or very near equally; each will in this case afford a market for a part of the surplus produce of the other; each will replace a capital which had been employed in raising and preparing for the market this part of the surplus produce of the other, and which had been distributed among, and given revenue and maintenance to a certain number of its inhabitants. Some part of the inhabitants of each, therefore, will indirectly derive their revenue and maintenance from the other. As the commodities exchanged, too, are supposed to be of equal value, so the two capitals employed in the trade will, upon most occasions, be equal, or very nearly equal; and both being employed in raising the native commodities of the two countries, the revenue and maintenance which their distribution will afford to the inhabitants of each will be equal, or very nearly equal. This revenue and maintenance, thus mutually afforded, will be greater or smaller in proportion to the extent of their dealings. If these should annually amount to an hundred thousand pounds, for example, or to a million on each side, each of them would afford an annual revenue in the one case of an hundred thousand pounds, in the other of a million, to the inhabitants of the other.
If their trade should be of such a nature that one of them exported to the other nothing but native commodities, while the returns of that other consisted altogether in foreign goods; the balance, in this case, would still be supposed even, commodities being paid for with commodities. They would, in this case too, both gain, but they would not gain equally; and the inhabitants of the country which exported nothing but native commodities would derive the greatest revenue from the trade. If England, for example, should import from France nothing but the native commodities of that country, and, not having such commodities of its own as were in demand there, should annually repay them by sending thither a large quantity of foreign goods, tobacco, we shall suppose, and East India goods; this trade, though it would give some revenue to the inhabitants of both countries, would give more to those of France than to those of England. The whole French capital annually employed in it would annually be distributed among the people of France. But that part of the English capital only which was employed in producing the English commodities with which those foreign goods were purchased would be annually distributed among the people of England. The greater part of it would replace the capitals which had been employed in Virginia, Indostan, and China, and which had given revenue and maintenance to the inhabitants of those distant countries. If the capitals were equal, or nearly equal, therefore this employment of the French capital would augment much more the revenue of the people of France than that of the English capital would the revenue of the people of England. France would in this case carry on a direct foreign trade of consumption with England; whereas England would carry on a round-about trade of the same kind with France. The different effects of a capital employed in the direct and of one employed in the round-about foreign trade of consumption have already been fully explained.
There is not, probably, between any two countries a trade which consists altogether in the exchange either of native commodities on both sides, or of native commodities on one side and of foreign goods on the other. Almost all countries exchange with one another partly native and partly foreign goods. That country, however, in whose cargoes there is the greatest proportion of native, and the least of foreign goods, will always be the principal gainer.
If it was not with tobacco and East India goods, but with gold and silver, that England paid for the commodities annually imported from France, the balance, in this case, would be supposed uneven, commodities not being paid for wi
th commodities, but with gold and silver. The trade, however, would, in this case, as in the foregoing, give some revenue to the inhabitants of both countries, but more to those of France than to those of England. It would give some revenue to those of England. The capital which had been employed in producing the English goods that purchased this gold and silver, the capital which had been distributed among, and given revenue to, certain inhabitants of England, would thereby be replaced and enabled to continue that employment. The whole capital of England would no more be diminished by this exportation of gold and silver than by the exportation of an equal value of any other goods. On the contrary, it would in most cases be augmented. No goods are sent abroad but those for which the demand is supposed to be greater abroad than at home, and of which the returns consequently, it is expected, will be of more value at home than the commodities exported. If the tobacco which, in England, is worth only a hundred thousand pounds, when sent to France will purchase wine which is, in England, worth a hundred and ten thousand, this exchange will equally augment the capital of England by ten thousand pounds. If a hundred thousand pounds of English gold, in the same manner, purchase French wine which, in England, is worth a hundred and ten thousand, this exchange will equally augment the capital of England by ten thousand pounds. As a merchant who has a hundred and ten thousand pounds worth of wine in his cellar is a richer man than he who has only a hundred thousand pounds worth of tobacco in his warehouse, so is he likewise a richer man than he who has only a hundred thousand pounds worth of gold in his coffers. He can put into motion a greater quantity of industry, and give revenue, maintenance, and employment to a greater number of people than either of the other two. But the capital of the country is equal to the capitals of all its different inhabitants, and the quantity of industry which can be annually maintained in it is equal to what all those different capitals can maintain. Both the capital of the country, therefore, and the quantity of industry which can be annually maintained in it, must generally be augmented by this exchange. It would, indeed, be more advantageous for England that it could purchase the wines of France with its own hardware and broadcloth than with either the tobacco of Virginia or the gold and silver of Brazil and Peru. A direct foreign trade of consumption is always more advantageous than a round-about one. But a round-about foreign trade of consumption, which is carried on with gold and silver, does not seem to be less advantageous than any other equally round-about one. Neither is a country which has no mines more likely to be exhausted of gold and silver by this annual exportation of those metals than one which does not grow tobacco by the like annual exportation of that plant. As a country which has wherewithal to buy tobacco will never be long in want of it, so neither will one be long in want of gold and silver which has wherewithal to purchase those metals.
