The Bank of France is not compelled to give gold in exchange for its circulating notes; it may at its option give silver. Thus, when it is inconvenient to give gold, the bank can refuse, or, if it prefers, it can exact a premium. This power has been very moderately and very wisely used by the bank to modify foreign demands on the one hand, and, on the other, to keep interest rates low for the requirements of internal trade. Of course, when a premium is exacted, the French gold import point drops accordingly.
Between the gold export point and the gold import point, exchange fluctuates under the sway of conflicting currents and tendencies—I had almost said emotions, for these currents and tendencies have their rise in emotions, needs, and passions as varied as life itself, whether they be hunger as expressed in the grain bill, or love of elegance in the importation of silk, or forethought in the profitable investment of capital.
This brief review will have made clear what is meant by a free gold market—a market in which current money can at all times be exchanged for gold without delay and without premium. Such a market has great commercial advantages; its stability draws business to it. London is such a market, and its commercial and financial pre-eminence is in great measure due to that fact. Paris is not such a market and does not pretend to be; Berlin pretends to be, but cannot always be counted on; New York was believed to be before our recent panic.
I have spoken of the exchange market as an economical mechanism, automatically making delicate international adjustments. In justification of that observation, let me direct attention to the manner in which gold, in moving from financial centre to financial centre, always travels by the most direct route, and that, too, not because some public official is charged with the duty of preventing waste, but because a private trader is trying to make a profit, and is incidentally serving the community; serving it perhaps better than if he had consciously determined to serve it.
Useful acts springing from self-interest have one very comforting aspect—we need have no misgivings as to their continuance. Charity may grow weary or disgusted, but self-interest, once enlisted, may be counted on to continue in operation, whether it be the business man's self-interest in a profit or the professional man's self-interest in advancement and fame. Of course, both the business man and the professional man, in addition to seeking the direct rewards of their labor, take an interest in their work as work and make it yield them pleasure.
It is therefore satisfactory to know that, so long as the banker looks after his profits, gold will move by the most direct route. Let us suppose the United States to be exporting a large quantity of cotton to England at a time when little merchandise is being imported here from England, but when much is being imported from France. If the volume of exports to England and of imports from France were large enough, we might conceivably be importing gold from England in payment of our produce, and exporting it to France in payment for her luxuries; but, in practice, gold does not move that way. Every morning, the New York exchange banker learns by cable the Paris market rate for demand bills on London. When, therefore, he finds a large volume of bills on London offered for sale, and little demand for such bills, while there is large demand for bills on Paris and little supply, he determines, instead of drawing from New York against his purchases of London bills, to let his Paris agent draw against these purchases, placing the proceeds to his credit in Paris; against this credit in Paris, the New York banker draws his bill in francs, having thus supplied via London the New York demand for bills on Paris. He knows how many dollars each pound sterling costs him in New York, and the Paris rate for bills on London tells him how many francs each pound sterling will net him in Paris, and so he can calculate how many cents each franc will cost him. Moreover, he is not the only banker in New York that receives cable quotations; and so with a large volume of London bills offered and little direct demand for such bills, and large demand for Paris bills with little direct supply, we get a situation where New York bankers, competing with each other to buy the London bills for use via Paris, prevent the price of sterling from falling to the gold import point; and then, as a result, these same bankers, competing with each other to supply the demand for Paris bills, by their competition prevent the Paris rate from rising to gold export point. Lastly, they compete with each other in Paris, where all are sellers of bills on London against their New York purchases of London bills, and by that competition they reduce the rate for London bills in Paris to the point, at which, other things being equal, gold will go from London to Paris. What has happened, therefore, is that instead of our importing gold from London, and then exporting it to Paris, it has gone direct from London to Paris.
COMPLICATIONS IN THE DETERMINATION OF GOLD POINTS
[118]It is safe to assert that when the exchanges go down to the point at which it pays better to ship gold from London than to buy a bill, gold will go. But in the first place, experts always differ as to where that point begins; and in the second, gold often leaves London long before there is any question of its being the more profitable form of remittance. In fact, it may be asserted that the foreign exchanges very seldom go down to the export gold point, because gold begins to go before they can get there.
It has often happened to me, when I was a financial journalist and had to try to find out the how and why of gold movements, to ask several of the most experienced and well-informed cambists in the city whether a gold shipment which had taken place had been made as a genuine exchange transaction or was done for some other reason, and to hear from one that there was a reasonable exchange profit on it, from another that there might be just a shade of a turn to be got out of it if you scraped it very hard with a knife, and from another that you could not find a particle of profit in it if you put it under a microscope for a week. So many complications have to be considered that the most eminent doctors may be pardoned for disagreeing.
