Although this business is still in its infancy, it has reached important proportions and there is an active market for them in New York City. A number of brokers have taken up the business of buying and selling acceptances. Every morning they make the rounds of the various banks with the list of the acceptances they have for sale and the rates at which they are willing to sell them. Incidentally, they also learn whether the banks have any acceptances for sale and at what rates. As the credit risk is practically eliminated, acceptances are a very attractive form of secondary reserve; they are, as a London banker once expressed it, a means of enabling the banker to eat his cake and have it too--the banker by investing his money in acceptances earns the discount and at the same time he knows that his money is instantly available in case of need, so that they are almost as available as cash. This explains why the discount rate on acceptances ranges so low. Ninety days' sight acceptances sold in New York City at one time as low as 2 per cent. per annum and to-day prime acceptances command the excellent rate of 2-3/8 per cent. THE ECONOMIES AND ADVANTAGES OF "DOLLAR CREDITS"[113] Many radical changes in the mechanism of international finance have occurred during the past fifteen months, since the beginning of the European war. Not the least important among these changes, viewed from the standpoint of the American importer, is the evolution in the methods of financing our importations. Our imports in the way of commodities such as hides, coffee, rubber, wool, etc., etc., run into hundreds of millions of dollars annually, and these are financed generally through the medium of commercial credits established by the purchaser in favor of the vendor of the merchandise. Commercial credits, so called, are in effect a bank guarantee to the seller that his drafts covering certain merchandise, when drawn in accordance with the conditions prescribed in the credit, will meet with due honor on presentation to the accepting bank named in the credit instrument. In order merely to gain an idea as to the importance and volume of such transactions, it is only necessary to glance at the totals of a few of our principal imports. In the year 1914 we imported, among other commodities, the following: Hides and skins $120,289,781.00 Coffee 110,725,392.00 Rubber 131,995,742.00 Wool (unmanufactured) 53,190,767.00 Prior to the outbreak of the war in Europe, it is safe to assume that fully 95 per cent. of the credits issued to cover these importations were passed through London in the form of sterling credits; that is to say, credits available by drafts drawn in pounds sterling on London. Requests for the issuance of credits available by drafts drawn in United States dollars on New York were extremely rare, and they were issued only in exceptional cases.
