An Inquiry into the Nature and Causes of the Wealth of Nations

by Adam Smith

It has been celebrated, however, as a masterpiece of the commercial policy of England. Portugal receives annually from the Brazils a greater quantity of gold than can be employed in its domestic commerce, whether in the shape of coin or of plate. The surplus is too valuable to be allowed to lie idle and locked up in coffers; and as it can find no advantageous market at home, it must, notwithstanding; any prohibition, be sent abroad, and exchanged for something for which there is a more advantageous market at home. A large share of it comes annually to England, in return either for English goods, or for those of other European nations that receive their returns through England. Mr Barretti was informed, that the weekly packet-boat from Lisbon brings, one week with another, more than £50,000 in gold to England. The sum had probably been exaggerated. It would amount to more than £2,600,000 a year, which is more than the Brazils are supposed to afford.

Our merchants were, some years ago, out of humour with the crown of Portugal. Some privileges which had been granted them, not by treaty, but by the free grace of that crown, at the solicitation, indeed, it is probable, and in return for much greater favours, defence and protection from the crown of Great Britain, had been either infringed or revoked. The people, therefore, usually most interested in celebrating the Portugal trade, were then rather disposed to represent it as less advantageous than it had commonly been imagined. The far greater part, almost the whole, they pretended, of this annual importation of gold, was not on account of Great Britain, but of other European nations; the fruits and wines of Portugal annually imported into Great Britain nearly compensating the value of the British goods sent thither.

Let us suppose, however, that the whole was on account of Great Britain, and that it amounted to a still greater sum than Mr Barretti seems to imagine; this trade would not, upon that account, be more advantageous than any other, in which, for the same value sent out, we received an equal value of consumable goods in return.

It is but a very small part of this importation which, it can be supposed, is employed as an annual addition, either to the plate or to the coin of the kingdom. The rest must all be sent abroad, and exchanged for consumable goods of some kind or other. But if those consumable goods were purchased directly with the produce of English industry, it would be more for the advantage of England, than first to purchase with that produce the gold of Portugal, and afterwards to purchase with that gold those consumable goods. A direct foreign trade of consumption is always more advantageous than a round-about one; and to bring the same value of foreign goods to the home market requires a much smaller capital in the one way than in the ether. If a smaller share of its industry, therefore, had been employed in producing goods fit for the Portugal market, and a greater in producing those lit for the other markets, where those consumable goods for which there is a demand in Great Britain are to be had, it would have been more for the advantage of England. To procure both the gold which it wants for its own use, and the consumable goods, would, in this way, employ a much smaller capital than at present. There would be a spare capital, therefore, to be employed for other purposes, in exciting an additional quantity of industry, and in raising a greater annual produce.

Though Britain were entirely excluded from the Portugal trade, it could find very little difficulty in procuring all the annual supplies of gold which it wants, either for the purposes of plate, or of coin, or of foreign trade. Gold, like every other commodity, is always somewhere or another to be got for its value by those who have that value to give for it. The annual surplus of gold in Portugal, besides, would still be sent abroad, and though not carried away by Great Britain, would be carried away by some other nation, which would be glad to sell it again for its price, in the same manner as Great Britain does at present. In buying gold of Portugal, indeed, we buy it at the first hand; whereas, in buying it of any other nation, except Spain, we should buy it at the second, and might pay somewhat dearer. This difference, however, would surely be too insignificant to deserve the public attention.

Almost all our gold, it is said, comes from Portugal. With other nations, the balance of trade is either against as, or not much in our favour. But we should remember, that the more gold we import from one country, the less we must necessarily import from all others. The effectual demand for gold, like that for every other commodity, is in every country limited to a certain quantity. If nine-tenths of this quantity are imported from one country, there remains a tenth only to be imported from all others. The more gold, besides, that is annually imported from some particular countries, over and above what is requisite for plate and for coin, the more must necessarily be exported to some others: and the more that most insignificant object of modern policy, the balance of trade, appears to be in our favour with some particular countries, the more it must necessarily appear to be against us with many others.

It was upon this silly notion, however, that England could not subsist without the Portugal trade, that, towards the end of the late war, France and Spain, without pretending either offence or provocation, required the king of Portugal to exclude all British ships from his ports, and, for the security of this exclusion, to receive into them French or Spanish garrisons. Had the king of Portugal submitted to those ignominious terms which his brother-in-law the king of Spain proposed to him, Britain would have been freed from a much greater inconveniency than the loss of the Portugal trade, the burden of supporting a very weak ally, so unprovided of every thing for his own defence, that the whole power of England, had it been directed to that single purpose, could scarce, perhaps, have defended him for another campaign. The loss of the Portugal trade would, no doubt, have occasioned a considerable embarrassment to the merchants at that time engaged in it, who might not, perhaps, have found out, for a year or two, any other equally advantageous method of employing their capitals; and in this would probably have consisted all the inconveniency which England could have suffered from this notable piece of commercial policy.

The great annual importation of gold and silver is neither for the purpose of plate nor of coin, but of foreign trade. A round-about foreign trade of consumption can be carried on more advantageously by means of these metals than of almost any other goods. As they are the universal instruments of commerce, they are more readily received in return for all commodities than any other goods; and, on account of their small bulk and great value, it costs less to transport them backward and forward from one place to another than almost any other sort of merchandize, and they lose less of their value by being so transported. Of all the commodities, therefore, which are bought in one foreign country, for no other purpose but to be sold or exchanged again for some other goods in another, there are none so convenient as gold and silver. In facilitating all the different round-about foreign trades of consumption which are carried on in Great Britain, consists the principal advantage of the Portugal trade; and though it is not a capital advantage, it is, no doubt, a considerable one.

That any annual addition which, it can reasonably be supposed, is made either to the plate or to the coin of the kingdom, could require but a very small annual importation of gold and silver, seems evident enough; and though we had no direct trade with Portugal, this small quantity could always, somewhere or another, be very easily got.

Though the goldsmiths trade be very considerable in Great Britain, the far greater part of the new plate which they annually sell, is made from other old plate melted down; so that the addition annually made to the whole plate of the kingdom cannot be very great, and could require but a very small annual importation.
