It is to be noted, however, that money rates are a great factor influencing foreign exchange. Whenever money is cheap at any given centre, and borrowers are bidding only low rates for its use, lenders seek a more profitable field for the employment of their capital.

Money rates in the New York market are not often less attractive than those in London, so that American floating capital is not generally employed in the English market, but it does occasionally come about that rates become abnormally low here and that bankers send away their balances to be loaned out at other points. Such a time was the long period of stagnant money conditions following the 1907 panic. Trust companies and banks who were paying interest on large deposits at that time sent very large amounts of money to the other side and kept big balances running with their correspondents at such points as Amsterdam, Copenhagen, St. Petersburg, etc.—anywhere, in fact, where some little demand for money actually existed. Demand for exchange with which to send this money abroad was a big factor in keeping exchange rates at their high level during all that long period.

High money rates at some given foreign point as a factor in elevating exchange rates on that point might almost be considered as a corollary of low money here, but special considerations often govern such a condition and make it worth while to note its effect. Suppose, for instance, that at a time when money market conditions all over the world are about normal, rates, for any given reason, begin to rise at some point, say London. Instantly a flow of capital begins in that direction. In New York, Paris, Berlin, and other centres it is realized that London is bidding better rates for money than are obtainable locally, and bankers forthwith make preparations to increase the sterling balances they are employing in London. Exchange on that particular point being in such demand, rates begin to rise, and continue to rise, according to the urgency of the demand.

The international money markets are a most decidedly complex proposition, and there is literally never a time when several influences tending to put exchange rates up are not conflicting with several influences tending to put rates down. The actual movement of the rate represents the relative strength of the two sets of influences. To be able to "size up" the influences present and to gauge what movement of rates they will result in, is an operation requiring, first, knowledge, then judgment. The former qualification can perhaps be derived, in small degree, from study of the foregoing pages. The latter is a matter of mental calibre and experience.

Methods of Financing Imports and Exports[107]

The foreign trade of the United States has increased during the last forty years about 370 per cent.... This increase ... reflected not alone our own marvellous development, but as well the wonderful growth of trade throughout the world. The United States stands third among the countries of the world, its foreign trade being exceeded only by that of the United Kingdom ... and Germany....

Our imports and exports[108] are being financed more and more by means of what are known as commercial letters of credit.... An explanation of the operation of the commercial letter of credit will ... disclose the methods and conditions under which our imports are financed.

The commercial letter of credit is an authorization, say of an American bank to its London correspondent, to honor drafts for its account drawn at various tenors by foreign shippers or others against shipments of merchandise to this country. These credits are of two kinds, documentary and clean. Under the documentary credit the London bank is authorized to accept drafts for the account of the American bank only when the bill of exchange is accompanied by certain documents described in the letter of credit. These documents may be the bills of lading for the goods, consular invoices, insurance certificates and possibly other papers. Probably a large proportion of such credits requires that drafts be drawn at sixty or ninety days' sight. So many elements of danger are involved in financing commodities under commercial letters of credit, even where the control of the goods is given to the bank issuing the credit or its agents, that the financial standing of those asking for credits must be the first consideration in their issuance. Dishonesty on the part of the shipper, resulting in a drawing under the credit against forged documents or against shipments of inferior merchandise, is always possible, and the financial responsibility of the buyer of the credit is all that stands between the banker issuing the credit and a loss in such cases.

In order to obtain a clear understanding of the working of a commercial letter of credit, we will take a concrete example and follow its every transaction. An importer of coffee (A) in New York purchases a certain number of bags of coffee from an exporter (B) in Brazil. A agrees to furnish B with a commercial letter of credit. B is not in position, we will say, to await the arrival of the coffee in New York and the return of a remittance before receiving his pay. A on the other hand is unable to remit B for the coffee before its receipt and sale to his customers. A goes to his banker in New York and requests him to authorize B to draw upon the New York banker's London correspondent at ninety days' sight with bills of lading for coffee to the amount of the purchase attached to the draft, consular invoice and insurance certificate, if B is to furnish insurance. If A's banker is willing to extend the credit he writes a letter (or uses a printed form), requesting his London banker to accept B's drafts upon presentation under the conditions already mentioned and others of minor importance. This letter is issued in duplicate, one copy going to the London banker, the other being delivered to A. A then mails the copy received by him to B. B thereupon arranges to ship the coffee, obtains the bill of lading, invoice, etc., and takes them with the copy of the credit to his banker in Brazil. A draft is then drawn on the London bank under the terms of the credit at ninety days' sight and is discounted by the Brazilian banker, the proceeds being placed to the credit of B's account or given to him in the form of a check or cash. The Brazilian banker then forwards the draft and documents, except such documents as the instructions may require to be forwarded direct to New York, to his London banker. He may secure discount of the bill at once by cable or await its arrival in London before doing so, or he may request his London banker to have the bill accepted and hold it for maturity. If the bill is discounted the Brazilian banker may draw against it immediately and thus put himself in funds to purchase other coffee bills. Upon receipt of the bill by the London correspondent it is presented to the London banker on whom it is drawn for acceptance. The acceptor bank examines the documents and if they are drawn according to the terms of the credit accepts the draft and returns it to the correspondent of the Brazilian bank, retaining the documents, which it then forwards to the New York bank which opened the credit. In accepting the draft the London bank has in effect agreed to pay it at the end of ninety days, or, figuring grace, ninety-three days. Upon maturity payment is made and the amount is charged to the account of the issuing New York bank. Upon receipt of the documents the New York bank delivers them to its customer under a trust receipt or against collateral, and the latter is then in position to obtain the goods. Ten days before the bill of exchange is due in London the New York bank collects the amount from A, together with the commission agreed upon when the credit was opened, and remits the amount to its London banker to meet the draft. On all such transactions the London banker, while not himself advancing any money, is extending a credit for which he charges the New York bank a commission. The result is that we are paying tribute to European bankers amounting to an immense sum annually for the purpose of financing our imports.

The fact that London exchange is more marketable generally throughout the world than New York exchange is one of the principal reasons why it is necessary for us to issue credits upon London instead of upon New York.
