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

by Adam Smith; M. Garnier

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 given 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 in 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 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 wore 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 an equal 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, &c. foreign bills of exchange are paid in what they call bank money; while in others, as at London, Lisbon, Antwerp, Leghorn, &c. 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 by 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.

Digression concerning Banks of Deposit, particularly concerning that of Amsterdam.

The currency of a great state, such as France or England, generally consists almost entirely of its own coin. Should this currency, therefore, be at any time worn, clipt, or otherwise degraded below its standard value, the state, by a reformation of its coin, can effectually re-establish its currency. But the currency of a small state, such as Genoa or Hamburg, can seldom consist altogether in its own coin, but must be made up, in a great measure, of the coins of all the neighbouring states with which its inhabitants have a continual intercourse. Such a state, therefore, by reforming its coin, will not always be able to reform its currency. If foreign bills of exchange are paid in this currency, the uncertain value of any sum, of what is in its own nature so uncertain, must render the exchange always very much against such a state, its currency being in all foreign states necessarily valued even below what it is worth.

In order to remedy the inconvenience to which this disadvantageous exchange must have subjected their merchants, such small states, when they began to attend to the interest of trade, have frequently enacted, that foreign bills of exchange of a certain value should be paid, not in common currency, but by an order upon, or by a transfer in the books of a certain bank, established upon the credit, and under the protection of the state, this bank being always obliged to pay, in good and true money, exactly according to the standard of the state. The banks of Venice, Genoa, Amsterdam, Hamburg, and Nuremberg, seem to have been all originally established with this view, though some of them may have afterwards been made subservient to other purposes. The money of such banks, being better than the common currency of the country, necessarily bore an agio, which was greater or smaller, according as the currency was supposed to be more or less degraded below the standard of the state. The agio of the bank of Hamburg, for example, which is said to be commonly about fourteen per cent. is the supposed difference between the good standard money of the state, and the clipt, worn, and diminished currency, poured into it from all the neighbouring states.

Before 1609, the great quantity of clipt and worn foreign coin which the extensive trade of Amsterdam brought from all parts of Europe, reduced the value of its currency about nine per cent. below that of good money fresh from the mint. Such money no sooner appeared, than it was melted down or carried away, as it always is in such circumstances. The merchants, with plenty of currency, could not always find a sufficient quantity of good money to pay their bills of exchange; and the value of those bills, in spite of several regulations which were made to prevent it, became in a great measure uncertain.

In order to remedy these inconveniences, a bank was established in 1609, under the guarantee of the city. This bank received both foreign coin, and the light and worn coin of the country, at its real intrinsic value in the good standard money of the country, deducting only so much as was necessary for defraying the expense of coinage and the other necessary expense of management. For the value which remained after this small deduction was made, it gave a credit in its books. This credit was called bank money, which, as it represented money exactly according to the standard of the mint, was always of the same real value, and intrinsically worth more than current money. It was at the same time enacted, that all bills drawn upon or negociated at Amsterdam, of the value of 600 guilders and upwards, should be paid in bank money, which at once took away all uncertainty in the value of those bills. Every merchant, in consequence of this regulation, was obliged to keep an account with the bank, in order to pay his foreign bills of exchange, which necessarily occasioned a certain demand for bank money.

Bank money, over and above both its intrinsic superiority to currency, and the additional value which this demand necessarily gives it, has likewise some other advantages. It is secure from fire, robbery, and other accidents; the city of Amsterdam is bound for it; it can be paid away by a simple transfer, without the trouble of counting, or the risk of transporting it from one place to another. In consequence of those different advantages, it seems from the beginning to have borne an agio; and it is generally believed that all the money originally deposited in the bank, was allowed to remain there, nobody caring to demand payment of a debt which he could sell for a premium in the market. By demanding payment of the bank, the owner of a bank credit would lose this premium. As a shilling fresh from the mint will buy no more goods in the market than one of our common worn shillings, so the good and true money which might be brought from the coffers of the bank into those of a private person, being mixed and confounded with the common currency of the country, would be of no more value than that currency, from which it could no longer be readily distinguished. While it remained in the coffers of the bank, its superiority was known and ascertained. When it had come into those of a private person, its superiority could not well be ascertained without more trouble than perhaps the difference was worth. By being brought from the coffers of the bank, besides, it lost all the other advantages of bank money; its security, its easy and safe transferability, its use in paying foreign bills of exchange. Over and above all this, it could not be brought from those coffers, as will appear by and by, without previously paying for the keeping.
