The bills sold by Smith & Jones find their way to London by the first steamer, are accepted and discounted. Ninety days later they will come due and have to be paid, and ten days prior to their maturity the New York Bank will be expecting Smith & Jones to send in a _demand_ draft for £100,000, plus three-eighths per cent. commission, making £375 additional. This £100,375, less its commission for having handled the loan, the New York Bank will send to London, where it will arrive a couple of days before the £100,000 of ninety days' sight bills originally drawn on the London Bank, Ltd., mature. What each of the bankers concerned makes out of the transaction is plain enough. As to what Smith & Jones' ninety-day loan cost them, in addition to the flat three-eighths per cent. they had to pay, that depends upon what they realize from the sale of the ninety days' sight bills in the first place and secondly on what rate they had to pay for the demand bill for £100,000. Exchange may have gone up during the life of the loan, making the loan expensive, or it may have gone down, making the cost very little. Plainly stated, unless they secured themselves by buying a "future" for the delivery of a £100,000 demand bill in ninety days at a fixed rate, Messrs. Smith & Jones have been making a mild speculation in foreign exchange. If the same loan had been made on the other basis, the New York Bank would have turned over to Smith & Jones not a _sterling bill_ for £100,000, but the _dollar proceeds_ of such a bill, say a check for $484,000. At the end of ninety days Smith & Jones would have had to pay back $484,000, plus ninety days' interest at six per cent, $7,260, all of which cash, less commission, the New York Bank would have invested in a demand bill of exchange and sent over to the London Bank, Ltd. Whatever more than the £100,000 needed to pay off the maturing nineties such a demand draft amounted to, would be the London Bank, Ltd.'s, profit. From all of which it is plainly to be seen that when the London bankers are willing to lend money here and figure that the exchange market is on the down track, they will insist upon doing their lending on the "currency loan" basis--taking the risk of exchange themselves. Conversely, when loaning operations seem profitable but rates seem to be on the upturn, lenders will do their best to put their money out in the form of "sterling loans." Bankers are not always right in their views, by any means, but as a general principle it can be said that when big amounts of foreign money offered in this market are all offered on the "sterling loan" basis, a rising exchange market is to be expected.
