Granted that the obligations to each other of any two given countries foot up to the same amount, it is evident that the rate of exchange will remain exactly at the gold par—that in New York, for instance, the price of the sovereign will be simply the mint value of the gold contained in the sovereign. But between no two countries does such a condition exist—take any two, and the amount of the obligation of one to the other changes every day, which causes a continuous fluctuation in the exchange rate—sometimes up from the mint par, sometimes down.
Before going on to discuss the various causes influencing the movement of exchange rates, there is one point which should be very clearly understood. Two countries, at least, are concerned in the fluctuation of every rate. Take, for example, London and New York, and assume that, at New York, exchange on London is falling. That in itself means that, in London, exchange on New York is rising.
For the sake of clearness, in the ensuing discussion of the influences tending to raise and lower exchange rates, New York is chosen as the point at which these influences are operative. Consideration will be given first to the influences which cause exchange to go up. In a general way, it will be noticed, they conform with the sources of demand for exchange given in the previous chapter. They may be classified about as follows:
1. Large imports, calling for large amounts of exchange with which to make the necessary payments.
2. Large purchases of foreign securities by us, or repurchase of our own securities abroad, calling for large amounts of exchange with which to make payment.
3. Coming to maturity of issues of American bonds held abroad.
4. Low money rates here, which result in a demand for exchange with which to send banking capital out of the country.
5. High money rates at some foreign centre which create a great demand for exchange drawn on that centre.
1. Heavy imports are always a potent factor in raising the level of exchange rates. Under whatever financial arrangement or from whatever point merchandise is imported into the United States, payment is almost invariably made by draft on London, Paris, or Berlin. At times when imports run especially heavy, demand from importers for exchange often outweighs every other consideration, forcing rates up to high levels. A practical illustration is to be found in the inpour of merchandise which took place just before the tariff legislation in 1909. Convinced that duties were to be raised, importers rushed millions of dollars' worth of merchandise of every description into the country. The result was that the demand for exchange became so great that in spite of the fact that it was the season when exports normally meant low exchange, rates were pushed up to the gold export point.
2. Heavy purchasing movements of our own or foreign securities, on the other side, are the second great influence making for high exchange. There come times when, for one reason or another, the movement of securities is all one way, and when it happens that for any cause we are the ones who are doing the buying, the exchange market is likely to be sharply influenced upward by the demand for bills with which to make payments. Such movements on a greater or less scale go on all the time and constitute one of the principal factors which exchange managers take into consideration in making their estimate of possible exchange market fluctuations.
