Such is the nature of foreign exchange business that bankers engaged in it are continually drawing their sixty and ninety days' sight bills in response to their own and their customers' needs. One example which might be cited is that of the importer who has a payment to make on the other side, sixty days from now, but who, having the money on hand, wants to make it at once. Under some circumstances such an importer might remit a demand draft on the basis of receiving a rebate of interest for the unexpired sixty days, but more likely he would go to a banker and buy from him a sixty days' sight draft for the exact amount of pounds he owed. The cost of such a draft—‌which would mature at the time the debt became due—‌would be less than the cost of a demand draft, the importer getting his rebate of interest out of the cheaper price he pays for the pounds he needs. Prepayments of this sort are responsible every day for very large drawings of bankers' long bills.

B. Long Bills Issued in the Operation of Lending Foreign Money

Bills of this kind represent by far the greater proportion of bankers' long bills sold in the exchange market. European bankers keep an enormous amount of floating capital loaned out in this market, in the making and renewing of which loans long bills are created as follows:

A banker on the other side decides to loan out, say, £100,000 in the New York market. Arrangements having been made, he cables his New York representative to draw ninety days' sight drafts on him for £100,000, the proceeds of which drafts are then loaned out for account of the foreign house. The matter of collateral, risk of exchange and, indeed, all the other detail, will be fully described in the succeeding chapters on how bankers make money out of exchange. For the time being it is merely necessary to note that every time a loan of foreign capital is made here—‌and there are days when millions of pounds are so loaned out—‌bankers' long bills for the full amount of the loans are created and find their way into the exchange market.

C. Bankers' Long Bills Drawn for the Purpose of Raising Money

Finance bills constitute the third kind of bankers' long exchange. In this case, again, detailed discussion must be put off until the chapter on foreign-exchange-bankers' operations, but the fact that bills of this kind constitute so important a part of the bankers' long bills to be had in the market, necessitates their classification in this place. Every time a banker here starts to use his credit abroad for the purpose of raising money—‌and there are times when the privilege is pretty freely availed of—‌he does it by drawing sixty or ninety days' sight drafts on his correspondents abroad. Finance bills, it may be said without question, are one of the most interesting forms of foreign exchange banking—‌at the same time one of the most useful and one of the most abused of privileges coming to the domestic banker by reason of his having strong banking connections abroad.
