Elements of Foreign Exchange: A Foreign Exchange Primer

"Where can I find a little book from which I can get a clear idea of how foreign exchange works, without going too deeply into it?"--that question, put to the author dozens of times and by many different kinds of people, is responsible for the existence of this little work. There are one or two well-written textbooks on foreign exchange, but never yet has the author come across a book which covered this subject in such a way that the man who knew little or nothing about it could pick up the book and within a few hours get a clear idea of how foreign exchange works,--the causes which bear upon its movement, its influence on the money and security markets, etc.

That is the object of this little book--to cover the ground of foreign exchange, but in such a way as to make the subject interesting and its treatment readable and comprehensible to the man without technical knowledge. Foreign exchange is no easy subject to understand; there are few important subjects which are. But, on the other hand, neither is it the complicated and abstruse subject which so many people seem to consider it--an idea only too often born of a look into some of the textbooks on exchange, with their formidable pages of tabulations, formulas, and calculations of all descriptions. For the average man there is little of interest in these intricacies of the subject. Many of the shrewdest and most successful exchange bankers in New York City, indeed, know less about them than do some of their clerks. What is needed is rather a clear and definite knowledge of the movement of exchange--why it moves as it does, what can be read from its movements, what effects its movements exert on the other markets. It is in the hope that something may be added to the general understanding of these important matters that this little book is offered to the public.

What Foreign Exchange Is and What Brings It Into Existence

Underlying the whole business of foreign exchange is the way in which obligations between creditors in one country and debtors in another have come to be settled--by having the creditor draw a draft directly upon the debtor or upon some bank designated by him. A merchant in New York has sold a bill of goods to a merchant in London, having thus become his creditor, say, for $5,000. To get his money, the merchant in New York will, in the great majority of cases, draw a sterling draft upon the debtor in London for a little over L1,000. This draft his banker will readily enough convert for him into dollars. The buying and selling and discounting of countless such bills of exchange constitute the very foundation of the foreign exchange business.

Not all international obligations are settled by having the creditor draw direct on the debtor. Sometimes gold is actually sent in payment. Sometimes the debtor goes to a banker engaged in selling drafts on the city where the obligation exists, gets such a draft from him and sends that. But in the vast majority of cases payment is effected as stated--by a draft drawn directly on the buyer of the goods. John Smith in London owes me money. I draw on him for L100, take the draft around to my bank and sell it at, say, 4.86, getting for it a check for $486.00. I have my money, and I am out of the transaction.

Obligations continually arising in the course of trade and finance between firms in New York and firms in London, it follows that every day in New York there will be merchants with sterling drafts on London which they are anxious to sell for dollars, and vice versa. The supply of exchange, therefore, varies with the obligations of one country to another. If merchants in New York, for instance, have sold goods in quantity in London, a great many drafts on London will be drawn and offered for sale in the New York exchange market. The supply, it will of course be apparent, varies. Sometimes there are many drafts for sale; sometimes very few. When there are a great many drafts offering, their makers will naturally have to accept a lower rate of exchange than when the supply is light.

The par of exchange between any two countries is the price of the gold unit of one expressed in the money of the other. Take England and the United States. The gold unit of England is the pound sterling. What is the price of as much gold as there is in a new pound sterling, expressed in American money? $4.8665. That amount of dollars and cents at any United States assay office will buy exactly as much gold as there is contained in a new British pound sterling, or sovereign, as the actual coin itself is called. 4.8665 is the mint par of exchange between Great Britain and the United States.

The fact that the gold in a new British sovereign (or pound sterling) is worth $4.8665 in our money by no means proves, however, that drafts payable in pounds in London can always be bought or sold for $4.8665 per pound. To reduce the case to a unit basis, suppose that you owed one pound in London, and that, finding it difficult to buy a draft to send in payment, you elected to send actual gold. The amount of gold necessary to settle your debt would cost $4.8665, in addition to which you would have to pay all the expenses of remitting. It would be cheaper, therefore, to pay considerably more than $4.8665 for a one-pound draft, and you would probably bid up until somebody consented to sell you the draft you wanted.

Which goes to show that the mint par is not what governs the price at which drafts in pounds sterling can be bought, but that demand and supply are the controlling factors. There are exporters who have been shipping merchandise and selling foreign exchange against the shipments all their lives who have never even heard of a mint par of exchange. All they know is, that when exports are running large and bills in great quantity are being offered, bankers are willing to pay them only low rates--$4.83 or $4.84, perhaps, for the commercial bills they want to sell for dollars. Conversely, when exports are running light and bills drawn against shipments are scarce, bankers may be willing to pay 4.87 or 4.88 for them.

For a clear understanding of the mechanics of the exchange market there is necessary a clear understanding of what the various forms of obligations are which bring foreign exchange into existence. Practically all bills originate from one of the following causes:

1. Merchandise has been shipped and the shipper draws his draft on the buyer or on a bank abroad designated by him.

2. Securities have been sold abroad and the seller is drawing on the buyer for the purchase price.

3. Foreign money is being loaned in this market, the operation necessitating the drawing of drafts on the lender.

4. Finance-bills are being drawn, i.e., a banker abroad is allowing a banker here to draw on him in pounds sterling at 60 or 90 days' sight in order that the drawer of the drafts may sell them (for dollars) and use the proceeds until the drafts come due and have to be paid.

1. Looking at these sources of supply in the order in which they are given, it is apparent, first, what a vast amount of foreign exchange originates from the direct export of merchandise from this country. Exports for the period given below have been as follows:

1913 $2,465,884,000 1912 2,204,322,000 1911 2,049,320,000 1910 1,744,984,000 1909 1,663,011,000

Not all of this merchandise is drawn against; in some cases the buyer abroad chooses rather to secure a dollar draft on some American bank and to send that in payment. But in the vast majority of cases the regular course is followed and the seller here draws on the buyer there.

There are times, therefore, when exchange originating from this source is much more plentiful than at others. During the last quarter of each year, for instance, when the cereal and cotton crop exports are at their height, exchange comes flooding into the New York market from all over the country, literally by the hundreds of millions of dollars. The natural effect is to depress rates--sometimes to a point where it becomes possible to use the cheaply obtainable exchange to buy gold on the other side.

In a following chapter a more detailed description of the New York exchange market is given, but in passing, it is well to note how the whole country's supply of commercial exchange, with certain exceptions, is focussed on New York. Chicago, Philadelphia, and one or two other large cities carry on a pretty large business in exchange, independent of New York, but by far the greater part of the commercial exchange originating throughout the country finds its way to the metropolis. For in New York are situated so many banks and bankers dealing in bills of exchange that a close market is always assured. The cotton exporter in Memphis can send the bills he has drawn on London or Liverpool to his broker in New York with the fullest assurance that they will be sold to the bankers at the highest possible rate of exchange anywhere obtainable.
