CHAPTER XVIII
FOREIGN EXCHANGE
The Nature of Foreign Exchange
[103]The bill, or order to pay money in a foreign centre, is the commodity that is actually bought and sold by dealers in foreign exchange, but it is better for the moment to leave bills out of consideration. They are only the tangible expression of the claim for money in another centre, and at this early stage of our inquiry it is better to keep our minds fixed on what is at the back of the bill, namely, the money in a foreign centre to which it gives its holder a claim. The French buyer of a bill on London buys it, as a rule, because by sending it to his English correspondent he can discharge a debt to him in English money. What he really buys with his francs is so many English pounds, and the labyrinth of the foreign exchanges is much easier to thread if, before we complicate the question by talking about bills, we keep our eye on the comparatively simple problem which is the key to the puzzle, namely, the exchange of one country's money for another's.
Thus stripped to its naked simplicity, the problem begins to look as if it were not a problem at all, and a critical inquirer may be excused for thinking that at least in the case of countries that use currencies based on the same metal, there ought to be no need for daily quotations of rates of exchange, because the relative value of their moneys ought to be constant. It is a natural question to ask, why should there be these daily fluctuations, and, since they are evidently there, what is the sense or purport of them? The answer is, that money in France and money in England are two different things, and the relative value of two different things is almost certain to fluctuate. Quite apart from any differences in the fineness of gold coined by two different countries, or the ease or difficulty with which a credit instrument can be turned into gold, mere distance is quite enough to make the difference that will create fluctuation in price. New York and Chicago use exactly the same currencies, but money in New York differs from money in Chicago by being nearly a thousand miles away, and consequently there are frequent variations in their relative value. The English and Australian sovereigns are identical in weight and fineness, but there is constant fluctuation in the buying power of the English sovereign as expressed in its brother that is circulating in the Antipodes.
These fluctuations are based on the same influence that sways the movements in the prices of all goods and services that are bought and sold, that is, the influence of supply and demand. Just as the price of boots, Consols, medical advice, football professionals, or anything else that can be the subject of a bargain, will depend in the end upon the number of people who want to buy them compared with that of those who want to sell them, at or near a certain figure, so the price of English pounds, when expressed in francs, guilders, milreis, or Australian sovereigns, depends on the number of people abroad who have to buy money in England as compared with the number of those who have money in England to sell. People abroad have to buy money in England when they owe money to Englishmen and want to pay it; and they have money in England to sell when Englishmen owe them money.
Jacques Bonhomme in Paris has been selling shiploads of Christmas kickshaws to John Robinson in London, and so has thousands of English pounds due to him by the said Robinson. But English pounds, as such, are not wanted by M. Bonhomme. He wants to sell them, to turn them into francs, the currency of his own country, with which he makes his daily payments at home. On the other hand, there are always plenty of Frenchmen who have imported English goods or have had services rendered by English bankers, or shipowners, or insurance companies, and so want to buy English money wherewith to pay their English creditors. So it follows that the price that M. Bonhomme will get for his English pounds will depend on the value of goods and services that other Frenchmen have been selling to England, so producing English pounds to be sold in Paris, as compared with the value of the claims that have to be met in London, for the satisfaction of which English pounds have to be bought. If the amount of English money on offer is bigger than the amount wanted, down will go the price of the English pound as expressed in francs, and the seller in francs will get less in francs for his pound. If the amount of English money wanted is the bigger, the price will go up, and the seller will get more for his pound. When the price goes down, the exchange is said to move against London, because there is a depreciation in the value of the sovereign as expressed in francs. When it goes up the exchange moves in favour of London, because the buying power of the sovereign is enhanced.
