2. The second great source of demand originates out of the necessity of making payment for securities purchased abroad. So far as the American participation in foreign bond issues is concerned, the past few years have seen very great developments.
Security operations involving a demand for foreign exchange are, however, by no means confined to American participation in foreign bond issues. Accumulated during the course of the past half century, there is a perfectly immense amount of American securities held all over Europe. The greater part of this investment is in bonds and remains untouched for years at a stretch. But then there come times when, for one reason or another, waves of selling pass over the European holdings of "Americans," and we are required to take back millions of dollars' worth of our stock and bonds. Such selling movements do not really get very far below the surface—they do not, for instance, disturb the great blocks of American bonds in which so large a proportion of many of the big foreign fortunes are invested. The same thing is true with stocks, though in that case the selling movements are more frequent and less important.
3. So great is the foreign investment of capital in this country that the necessity of remitting the interest and dividends alone means another continuous demand for very large amounts of foreign exchange. Estimates of how much European money is invested here are little better than guesses. The only sure thing about it is that the figures run well up into the billions and that several hundred millions of dollars' worth of interest and dividends must be sent across the water each year. At the interest periods at the beginning and middle of each year it becomes apparent how large a proportion of our bonds are held in Europe and how great is the demand for exchange with which to make the remittances of accrued interest. At such times the incoming mails of the international banking houses bulge with great quantities of coupons sent over here for collection. For several weeks on either side of the two important interest periods, the exchange market feels the stimulus of the demand for exchange with which the proceeds of these masses of coupons are to be sent abroad.
4. Freights and insurance are responsible for a fourth important source of demand for foreign exchange. A walk along William Street in New York is all that is necessary to give a good idea of the number and importance of the foreign companies doing business in the United States. In some form or other all the premiums paid have to be sent to the other side. Times come, of course, like the year of the Baltimore fire, when losses by these foreign companies greatly outbalance premiums received, the business they do thus resulting in the actual creation of great amounts of foreign exchange, but in the long run—year in, year out—the remitting abroad of the premiums earned means a steady demand for exchange.
With freights it is the same proposition, except that the proportion of American shipping business done by foreign companies is much greater than the proportion of insurance business done by foreign companies. An estimate that the yearly freight bill amounts to $150,000,000 is probably not too high. That means that in the course of every year there is a demand for that amount of exchange with which to remit back what has been earned from us.
5. Tourists' expenditures abroad are responsible for a further heavy demand for exchange. The sums spent by American tourists in foreign lands annually aggregate a very large amount—possibly as much as $175,000,000—all of which has eventually to be covered by remittances of exchange from this side.
Then again there must be considered the expenditures of wealthy Americans who either live abroad entirely or else spend a large part of their time on the other side. By these expatriates money is spent extremely freely, their drafts on London and Paris requiring the frequent replenishment, by remittances of exchange from this side, of their bank balances at those points. Furthermore, there must be considered the great amounts of American capital transferred abroad by the marriage of wealthy American women with titled foreigners. Such alliances mean not only the transfer of large amounts of capital en bloc, but mean as well, usually, an annual remittance of a very large sum of money. No account of the money drained out of the country in this way is kept, of course, but it is an item which certainly runs up into the tens of millions.
6. Lastly, there is the demand for exchange originating from the paying off of the short-term loans which European bankers so continuously make in the American market.
These loaning operations, it must be understood, both originate exchange and create a demand for it. They were mentioned as one of the sources from which exchange originates, and now as one of the sources from which, during the course of every year, springs a demand for a very great quantity of exchange.
In a general way, it may be pointed out, the sources of demand for exchange conform with influences which cause exchange to go up, and the sources of supply of exchange constitute causes which make for low rates.
