Turning now to consideration of the various sources from which springs the demand for foreign exchange, it appears that they can be divided about as follows:

1. The need for exchange with which to pay for imports of merchandise.

2. The need for exchange with which to pay for securities (American or foreign) purchased by us in Europe.

3. The necessity of remitting abroad the interest and dividends on the huge sums of foreign capital invested here, and the money which foreigners domiciled in this country are continually sending home.

4. The necessity of remitting abroad freight and insurance money earned here by foreign companies.

5. Money to cover American tourists' disbursements and expenses of wealthy Americans living abroad.

6. The need for exchange with which to pay off maturing foreign short-loans and finance-bills.

1. Payment for merchandise imported constitutes probably the most important source of demand for foreign exchange. Merchandise brought into the country for the period given herewith has been valued as follows:

1913 $1,813,008,000
1912 1,653,264,000
1911 1,527,226,000
1910 1,556,947,000
1909 1,311,920,000

Practically the whole amount of these huge importations has had to be paid for with bills of exchange. Whether the merchandise in question is cutlery manufactured in England or coffee grown in Brazil, the chances are it will be paid for (under a system to be described hereafter) by a bill of exchange drawn on London or some other great European financial center. From one year's end to the other there is constantly this demand for bills with which to pay for merchandise brought into the country. As in the case of exports, which are largest in the Fall, there is much more of a demand for exchange with which to pay for imports at certain times of the year than at others, but at all times merchandise in quantity is coming into the country and must be paid for with bills of exchange.

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. We are not yet a people, as are the English or the French, who invest a large proportion of their accumulated savings outside of their own country, but as our investment surplus has increased in size, it has come about that American investors have been going in more and more extensively for foreign bonds. There have been times, indeed, as when the Japanese loans were being floated, when very large amounts of foreign exchange were required to pay for the bonds taken by American individuals and syndicates.

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 stocks 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, but they are apt to be, nevertheless, on a scale which requires large amounts of exchange to pay for what we have had to buy back.

The same thing is true with stocks, though in that case the selling movements are more frequent and less important. Europe is always interested heavily in American stocks, there being, as in the case of bonds, a big fixed investment of capital, beside a continually fluctuating "floating-investment." In other words, aside from their fixed investments in our stocks, the foreigners are continually speculating in them and continually changing their position as buyers and sellers. Selling movements such as these do not materially affect Europe's set position on our stocks, but they do result at times in very large amounts of our stocks being dumped back upon us—‌sometimes when we are ready for them, sometimes when the operation is decidedly painful, as in the Fall of 1907. In any case, when Europe sells, we buy. And when we buy, and at the rate of millions of dollars' worth a day, there is a big demand for exchange with which to pay for what we have bought.
