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

by Adam Smith

Those arguments were partly solid and partly sophistical. They were solid, so far as they asserted that the exportation of gold and silver in trade might frequently be advantageous to the country. They were solid, too, in asserting that no prohibition could prevent their exportation, when private people found any advantage in exporting them. But they were sophistical, in supposing, that either to preserve or to augment the quantity of those metals required more the attention of government, than to preserve or to augment the quantity of any other useful commodities, which the freedom of trade, without any such attention, never fails to supply in the proper quantity. They were sophistical, too, perhaps, in asserting that the high price of exchange necessarily increased what they called the unfavourable balance of trade, or occasioned the exportation of a greater quantity of gold and silver. That high price, indeed, was extremely disadvantageous to the merchants who had any money to pay in foreign countries. They paid so much dearer for the bills which their bankers granted them upon those countries. But though the risk arising from the prohibition might occasion some extraordinary expense to the bankers, it would not necessarily carry any more money out of the country. This expense would generally be all laid out in the country, in smuggling the money out of it, and could seldom occasion the exportation of a single sixpence beyond the precise sum drawn for. The high price of exchange, too, would naturally dispose the merchants to endeavour to make their exports nearly balance their imports, in order that they might have this high exchange to pay upon as small a sum as possible. The high price of exchange, besides, must necessarily have operated as a tax, in raising the price of foreign goods, and thereby diminishing their consumption. It would tend, therefore, not to increase, but to diminish, what they called the unfavourable balance of trade, and consequently the exportation of gold and silver.

Such as they were, however, those arguments convinced the people to whom they were addressed. They were addressed by merchants to parliaments and to the councils of princes, to nobles, and to country gentlemen; by those who were supposed to understand trade, to those who were conscious to them selves that they knew nothing about the matter. That foreign trade enriched the country, experience demonstrated to the nobles and country gentlemen, as well as to the merchants; but how, or in what manner, none of them well knew. The merchants knew perfectly in what manner it enriched themselves, it was their business to know it. But to know in what manner it enriched the country, was no part of their business. The subject never came into their consideration, but when they had occasion to apply to their country for some change in the laws relating to foreign trade. It then became necessary to say something about the beneficial effects of foreign trade, and the manner in which those effects were obstructed by the laws as they then stood. To the judges who were to decide the business, it appeared a most satisfactory account of the matter, when they were told that foreign trade brought money into the country, but that the laws in question hindered it from bringing so much as it otherwise would do. Those arguments, therefore, produced the wished-for effect. The prohibition of exporting gold and silver was, in France and England, confined to the coin of those respective countries. The exportation of foreign coin and of bullion was made free. In Holland, and in some other places, this liberty was extended even to the coin of the country. The attention of government was turned away from guarding against the exportation of gold and silver, to watch over the balance of trade, as the only cause which could occasion any augmentation or diminution of those metals. From one fruitless care, it was turned away to another care much more intricate, much more embarrassing, and just equally fruitless. The title of Mun’s book, England’s Treasure in Foreign Trade, became a fundamental maxim in the political economy, not of England only, but of all other commercial countries. The inland or home trade, the most important of all, the trade in which an equal capital affords the greatest revenue, and creates the greatest employment to the people of the country, was considered as subsidiary only to foreign trade. It neither brought money into the country, it was said, nor carried any out of it. The country, therefore, could never become either richer or poorer by means of it, except so far as its prosperity or decay might indirectly influence the state of foreign trade.

A country that has no mines of its own, must undoubtedly draw its gold and silver from foreign countries, in the same manner as one that has no vineyards of its own must draw its wines. It does not seem necessary, however, that the attention of government should be more turned towards the one than towards the other object. A country that has wherewithal to buy wine, will always get the wine which it has occasion for; and a country that has wherewithal to buy gold and silver, will never be in want of those metals. They are to be bought for a certain price, like all other commodities; and as they are the price of all other commodities, so all other commodities are the price of those metals. We trust, with perfect security, that the freedom of trade, without any attention of government, will always supply us with the wine which we have occasion for; and we may trust, with equal security, that it will always supply us with all the gold and silver which we can afford to purchase or to employ, either in circulating our commodities or in other uses.

The quantity of every commodity which human industry can either purchase or produce, naturally regulates itself in every country according to the effectual demand, or according to the demand of those who are willing to pay the whole rent, labour, and profits, which must be paid in order to prepare and bring it to market. But no commodities regulate themselves more easily or more exactly, according to this effectual demand, than gold and silver; because, on account of the small bulk and great value of those metals, no commodities can be more easily transported from one place to another; from the places where they are cheap, to those where they are dear; from the places where they exceed, to those where they fall short of this effectual demand. If there were in England, for example, an effectual demand for an additional quantity of gold, a packet-boat could bring from Lisbon, or from wherever else it was to be had, fifty tons of gold, which could be coined into more than five millions of guineas. But if there were an effectual demand for grain to the same value, to import it would require, at five guineas a-ton, a million of tons of shipping, or a thousand ships of a thousand tons each. The navy of England would not be sufficient.

When the quantity of gold and silver imported into any country exceeds the effectual demand, no vigilance of government can prevent their exportation. All the sanguinary laws of Spain and Portugal are not able to keep their gold and silver at home. The continual importations from Peru and Brazil exceed the effectual demand of those countries, and sink the price of those metals there below that in the neighbouring countries. If, on the contrary, in any particular country, their quantity fell short of the effectual demand, so as to raise their price above that of the neighbouring countries, the government would have no occasion to take any pains to import them. If it were even to take pains to prevent their importation, it would not be able to effectuate it. Those metals, when the Spartans had got wherewithal to purchase them, broke through all the barriers which the laws of Lycurgus opposed to their entrance into Lacedaemon. All the sanguinary laws of the customs are not able to prevent the importation of the teas of the Dutch and Gottenburg East India companies; because somewhat cheaper than those of the British company. A pound of tea, however, is about a hundred times the bulk of one of the highest prices, sixteen shillings, that is commonly paid for it in silver, and more than two thousand times the bulk of the same price in gold, and, consequently, just so many times more difficult to smuggle.

It is partly owing to the easy transportation of gold and silver, from the places where they abound to those where they are wanted, that the price of those metals does not fluctuate continually, like that of the greater part of other commodities, which are hindered by their bulk from shifting their situation, when the market happens to be either over or under-stocked with them. The price of those metals, indeed, is not altogether exempted from variation; but the changes to which it is liable are generally slow, gradual, and uniform. In Europe, for example, it is supposed, without much foundation, perhaps, that during the course of the present and preceding century, they have been constantly, but gradually, sinking in their value, on account of the continual importations from the Spanish West Indies. But to make any sudden change in the price of gold and silver, so as to raise or lower at once, sensibly and remarkably, the money price of all other commodities, requires such a revolution in commerce as that occasioned by the discovery of America.

If, not withstanding all this, gold and silver should at any time fall short in a country which has wherewithal to purchase them, there are more expedients for supplying their place, than that of almost any other commodity. If the materials of manufacture are wanted, industry must stop. If provisions are wanted, the people must starve. But if money is wanted, barter will supply its place, though with a good deal of inconveniency. Buying and selling upon credit, and the different dealers compensating their credits with one another, once a-month, or once a-year, will supply it with less inconveniency. A well-regulated paper-money will supply it not only without any inconveniency, but, in some cases, with some advantages. Upon every account, therefore, the attention of government never was so unnecessarily employed, as when directed to watch over the preservation or increase of the quantity of money in any country.

No complaint, however, is more common than that of a scarcity of money. Money, like wine, must always be scarce with those who have neither wherewithal to buy it, nor credit to borrow it. Those who have either, will seldom be in want either of the money, or of the wine which they have occasion for. This complaint, however, of the scarcity of money, is not always confined to improvident spendthrifts. It is sometimes general through a whole mercantile town and the country in its neighbourhood. Over-trading is the common cause of it. Sober men, whose projects have been disproportioned to their capitals, are as likely to have neither wherewithal to buy money, nor credit to borrow it, as prodigals, whose expense has been disproportioned to their revenue. Before their projects can be brought to bear, their stock is gone, and their credit with it. They run about everywhere to borrow money, and everybody tells them that they have none to lend. Even such general complaints of the scarcity of money do not always prove that the usual number of gold and silver pieces are not circulating in the country, but that many people want those pieces who have nothing to give for them. When the profits of trade happen to be greater than ordinary over-trading becomes a general error, both among great and small dealers. They do not always send more money abroad than usual, but they buy upon credit, both at home and abroad, an unusual quantity of goods, which they send to some distant market, in hopes that the returns will come in before the demand for payment. The demand comes before the returns, and they have nothing at hand with which they can either purchase money or give solid security for borrowing. It is not any scarcity of gold and silver, but the difficulty which such people find in borrowing, and which their creditor find in getting payment, that occasions the general complaint of the scarcity of money.

It would be too ridiculous to go about seriously to prove, that wealth does not consist in money, or in gold and silver; but in what money purchases, and is valuable only for purchasing. Money, no doubt, makes always a part of the national capital; but it has already been shown that it generally makes but a small part, and always the most unprofitable part of it.

It is not because wealth consists more essentially in money than in goods, that the merchant finds it generally more easy to buy goods with money, than to buy money with goods; but because money is the known and established instrument of commerce, for which every thing is readily given in exchange, but which is not always with equal readiness to be got in exchange for every thing. The greater part of goods, besides, are more perishable than money, and he may frequently sustain a much greater loss by keeping them. When his goods are upon hand, too, he is more liable to such demands for money as he may not be able to answer, than when he has got their price in his coffers. Over and above all this, his profit arises more directly from selling than from buying; and he is, upon all these accounts, generally much more anxious to exchange his goods for money than his money for goods. But though a particular merchant, with abundance of goods in his warehouse, may sometimes be ruined by not being able to sell them in time, a nation or country is not liable to the same accident, The whole capital of a merchant frequently consists in perishable goods destined for purchasing money. But it is but a very small part of the annual produce of the land and labour of a country, which can ever be destined for purchasing gold and silver from their neighbours. The far greater part is circulated and consumed among themselves; and even of the surplus which is sent abroad, the greater part is generally destined for the purchase of other foreign goods. Though gold and silver, therefore, could not be had in exchange for the goods destined to purchase them, the nation would not be ruined. It might, indeed, suffer some loss and inconveniency, and be forced upon some of those expedients which are necessary for supplying the place of money. The annual produce of its land and labour, however, would be the same, or very nearly the same as usual; because the same, or very nearly the same consumable capital would be employed in maintaining it. And though goods do not always draw money so readily as money draws goods, in the long-run they draw it more necessarily than even it draws them. Goods can serve many other purposes besides purchasing money, but money can serve no other purpose besides purchasing goods. Money, therefore, necessarily runs after goods, but goods do not always or necessarily run after money. The man who buys, does not always mean to sell again, but frequently to use or to consume; whereas he who sells always means to buy again. The one may frequently have done the whole, but the other can never have done more than the one half of his business. It is not for its own sake that men desire money, but for the sake of what they can purchase with it.
