The Wealth of Nations_ Books 4-5 - Adam Smith [99]
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 everything 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 merchandise, 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.
It is the same case with the coin. Nobody imagines, I believe, that even the greater part of the annual coinage, amounting, for ten years together, before the late reformation of the gold coin, to upwards of eight hundred thousand pounds a year in gold, was an annual addition to the money before current in the kingdom. In a country where the expense of the coinage is defrayed by the government, the value of the coin, even when it contains its full standard weight of gold and silver, can never be much greater than that of an equal quantity of those metals uncoined; because it requires only the trouble of going to the mint, and the delay perhaps of a few weeks, to procure for any quantity of uncoined gold and silver an equal quantity of those metals in coin. But, in every country, the greater part of the current coin is almost always more or less worn, or otherwise degenerated from its standard. In Great Britain it was, before the late reformation, a good deal so, the gold being more than two per cent. and the silver more than eight per cent. below
