The first and most elementary form of activity is, of course, the buying of demand bills at a certain price and the selling of the banker's own demand drafts against them at a higher price. A banker finds, for instance, that he can buy John Smith & Co.'s sight draft for £1,000, on London, at the rate of 4.86, and that he can sell his own draft for £1,000 on his London banking correspondent at 4.87. All he has to do, therefore, is to buy John Smith's draft for $4,860, send it to London for credit of his account there, and then draw his own draft for £1,000 on the newly created balance, selling it for $4,870. It cost him $4,860 to buy the commercial draft, and he has sold his own draft against it for $4,870. His gross profit on the transaction, therefore, is $10.
As may be imagined, not very much money is made in transactions exactly of this kind—the one cited is taken only because it illustrates the principle. For whether the banker sends over in every mail a bewildering assortment of every conceivable form of foreign exchange to be credited to his account abroad, or whether he confines himself to remittances of the simplest kind of bills, the idea remains exactly the same—he is depositing money to the credit of his account in order that he may have a balance on which he can draw. That is, indeed, the sum and substance of the exchange business of the foreign department of most banking houses—the maintaining of deposit accounts in banks at foreign centres on which deposit account the bank here is in a position to draw according to the wants and needs of its customers.
II. SELLING CABLES AGAINST DEMAND EXCHANGE
A "cable," so-called, differs from a sight draft only in that the banker abroad who is to pay out the money is advised to do so by means of a telegraphic message instead of by a bit of paper instructing him to "pay to the order of so and so."
Under ordinary circumstances foreign exchange dealers who engage in the business of selling cables carry adequate balances on the other side, balances which they keep replenishing by continuous remittances of demand exchange.
III. SELLING "DEMAND" BILLS AGAINST REMITTANCES OF LONG BILLS
If there is a stock operation in the conduct of a foreign exchange business it is the selling by bankers of their demand bills of exchange against remittances of commercial and bankers' long paper. Bills of the latter class make up the bulk of foreign exchange traded in, and its disposal naturally is the most important phase of foreign exchange business. What the foreign exchange business really is grounded on is the existence of commercial bills called into existence by exports of merchandise.
Buying and remitting commercial long bills is no pastime for an inexperienced man. Entirely aside from the question of rate, and profit on the exchange end of the transaction, there must be taken into consideration the matter of the credit of the drawer and the drawee, the salability of the merchandise specified in the bill of lading, and a number of other important points.
Where documents accompany the draft and the merchandise is formally hypothecated to the buyer of the draft, it might not be thought that the standing of the drawer would be of such great importance. Possession of the merchandise, it is true, gives the banker a certain form of security in case acceptance of the bill is refused by the parties on whom it is drawn or in case they refuse to pay it when it comes due, but the disposal of such collateral is a burdensome and often expensive operation. The banker in New York who buys a sixty-day draft drawn against a shipment of butter is presumably not an expert on the butter market and if he should be forced to sell the butter, might not be able to do so to the fullest possible advantage. Employment of an expert agent is an expensive operation, and, moreover, there is always the danger of legal complication arising out of the banker's having sold the collateral. It is desirable in every way that if there is to be any trouble about the acceptance or payment of a draft, the banker should keep himself out of it.
The successive steps in an actual transaction are as follows:
