The Wealth of Nations

The stock which is lent at interest is always considered as a capital by the lender. He expects that in due time it is to be restored to him, and that, in the mean time, the borrower is to pay him a certain annual rent for the use of it. The borrower may use it either as a capital, or as a stock reserved for immediate consumption. If he uses it as a capital, he employs it in the maintenance of productive labourers, who reproduce the value, with a profit. He can, in this case, both restore the capital, and pay the interest, without alienating or encroaching upon any other source of revenue. If he uses it as a stock reserved for immediate consumption, he acts the part of a prodigal, and dissipates, in the maintenance of the idle, what was destined for the support of the industrious. He can, in this case, neither restore the capital nor pay the interest, without either alienating or encroaching upon some other source of revenue, such as the property or the rent of land. The stock which is lent at interest is, no doubt, occasionally employed in both these ways, but in the former much more frequently than in the latter. The man who borrows in order to spend will soon be ruined, and he who lends to him will generally have occasion to repent of his folly. To borrow or to lend for such a purpose, therefore, is, in all cases, where gross usury is out of the question, contrary to the interest of both parties; and though it no doubt happens sometimes, that people do both the one and the other, yet, from the regard that all men have for their own interest, we may be assured, that it cannot happen so very frequently as we are sometimes apt to imagine. Ask any rich man of common prudence, to which of the two sorts of people he has lent the greater part of his stock, to those who he thinks will employ it profitably, or to those who will spend it idly, and he will laugh at you for proposing the question. Even among borrowers, therefore, not the people in the world most famous for frugality, the number of the frugal and industrious surpasses considerably that of the prodigal and idle. The only people to whom stock is commonly lent, without their being expected to make any very profitable use of it, are country gentlemen, who borrow upon mortgage. Even they scarce ever borrow merely to spend. What they borrow, one may say, is commonly spent before they borrow it. They have generally consumed so great a quantity of goods, advanced to them upon credit by shop-keepers and tradesmen, that they find it necessary to borrow at interest, in order to pay the debt. The capital borrowed replaces the capitals of those shop-keepers and tradesmen which the country gentlemen could not have replaced from the rents of their estates. It is not properly borrowed in order to be spent, but in order to replace a capital which had been spent before. Almost all loans at interest are made in money, either of paper, or of gold and silver; but what the borrower really wants, and what the lender readily supplies him with, is not the money, but the money’s worth, or the goods which it can purchase. If he wants it as a stock for immediate consumption, it is those goods only which he can place in that stock. If he wants it as a capital for employing industry, it is from those goods only that the industrious can be furnished with the tools, materials, and maintenance necessary for carrying on their work. By means of the loan, the lender, as it were, assigns to the borrower his right to a certain portion of the annual produce of the land and labour of the country, to be employed as the borrower pleases. The quantity of stock, therefore, or, as it is commonly expressed, of money, which can be lent at interest in any country, is not regulated by the value of the money, whether paper or coin, which serves as the instrument of the different loans made in that country, but by the value of that part of the annual produce, which, as soon as it comes either from the ground, or from the hands of the productive labourers, is destined, not only for replacing a capital, but such a capital as the owner does not care to be at the trouble of employing himself. As such capitals are commonly lent out and paid back in money, they constitute what is called the monied interest. It is distinct, not only from the landed, but from the trading and manufacturing interests, as in these last the owners themselves employ their own capitals. Even in the monied interest, however, the money is, as it were, but the deed of assignment, which conveys from one hand to another those capitals which the owners do not care to employ themselves. Those capitals may be greater, in almost any proportion, than the amount of the money which serves as the instrument of their conveyance; the same pieces of money successively serving for many different loans, as well as for many different purchases. A, for example, lends to W £1000, with which W immediately purchases of B £1000 worth of goods. B having no occasion for the money himself, lends the identical pieces to X, with which X immediately purchases of C another £1000 worth of goods. C, in the same manner, and for the same reason, lends them to Y, who again purchases goods with them of D. In this manner, the same pieces, either of coin or of paper, may, in the course of a few days, serve as the Instrument of three different loans, and of three different purchases, each of which is, in value, equal to the whole amount of those pieces. What the three monied men, A, B, and C, assigned to the three borrowers, W, X, and Y, is the power of making those purchases. In this power consist both the value and the use of the loans. The stock lent by the three monied men is equal to the value of the goods which can be purchased with it, and is three times greater than that of the money with which the purchases are made. Those loans, however, may be all perfectly well secured, the goods purchased by the different debtors being so employed as, in due time, to bring back, with a profit, an equal value either of coin or of paper. And as the same pieces of money can thus serve as the instrument of different loans to three, or, for the same reason, to thirty times their value, so they may likewise successively serve as the instrument of repayment. A capital lent at interest may, in this manner, be considered as an assignment, from the lender to the borrower, of a certain considerable portion of the annual produce, upon condition that the burrower in return shall, during the continuance of the loan, annually assign to the lender a small portion, called the interest; and, at the end of it, a portion equally considerable with that which had originally been assigned to him, called the repayment. Though money, either coin or paper, serves generally as the deed of assignment, both to the smaller and to the more considerable portion, it is itself altogether different from what is assigned by it. In proportion as that share of the annual produce which, as soon as it comes either from the ground, or from the hands of the productive labourers, is destined for replacing a capital, increases in any country, what is called the monied interest naturally increases with it. The increase of those particular capitals from which the owners wish to derive a revenue, without being at the trouble of employing them themselves, naturally accompanies the general increase of capitals; or, in other words, as stock increases, the quantity of stock to be lent at interest grows gradually greater and greater. As the quantity of stock to be lent at interest increases, the interest, or the price which must be paid for the use of that stock, necessarily diminishes, not only from those general causes which make the market price of things commonly diminish as their quantity increases, but from other causes which are peculiar to this particular case. As capitals increase in any country, the profits which can be made by employing them necessarily diminish. It becomes gradually more and more difficult to find within the country a profitable method of employing any new capital. There arises, in consequence, a competition between different capitals, the owner of one endeavouring to get possession of that employment which is occupied by another; but, upon most occasions, he can hope to justle that other out of this employment by no other means but by dealing upon more reasonable terms. He must not only sell what he deals in somewhat cheaper, but, in order to get it to sell, he must sometimes, too, buy it dearer. The demand for productive labour, by the increase of the funds which are destined for maintaining it, grows every day greater and greater. Labourers easily find employment; but the owners of capitals find it difficult to get labourers to employ. Their competition raises the wages of labour, and sinks the profits of stock. But when the profits which can be made by the use of a capital are in this manner diminished, as it were, at both ends, the price which can be paid for the use of it, that is, the rate of interest, must necessarily be diminished with them. Mr Locke, Mr Lawe, and Mr Montesquieu, as well as many other writers, seem to have imagined that the increase of the quantity of gold and silver, in consequence of the discovery of the Spanish West Indies, was the real cause of the lowering of the rate of interest through the greater part of Europe. Those metals, they say, having become of less value themselves, the use of any particular portion of them necessarily became of less value too, and, consequently, the price which could be paid for it. This notion, which at first sight seems so plausible, has been so fully exposed by Mr Hume, that it is, perhaps, unnecessary to say any thing more about it. The following very short and plain argument, however, may serve to explain more distinctly the fallacy which seems to have misled those gentlemen. Before the discovery of the Spanish West Indies, ten per cent. seems to have been the common rate of interest through the greater part of Europe. It has since that time, in different countries, sunk to six, five, four, and three per cent. Let us suppose, that in every particular country the value of silver has sunk precisely in the same proportion as the rate of interest; and that in those countries, for example, where interest has been reduced from ten to five per cent. the same quantity of silver can now purchase just half the quantity of goods which it could have purchased before. This supposition will not, I believe, be found anywhere agreeable to the truth; but it is the most favourable to the opinion which we are going to examine; and, even upon this supposition, it is utterly impossible that the lowering of the value of silver could have the smallest tendency to lower the rate of interest. If £100 are in those countries now of no more value than £50 were then, £10 must now be of no more value than £5 were then. Whatever were the causes which lowered the value of the capital, the same must necessarily have lowered that of the interest, and exactly in the same proportion. The proportion between the value of the capital and that of the interest must have remained the
