The fact that the gold in a new British sovereign (or pound sterling) is worth $4.8665 in our money by no means proves, however, that drafts payable in pounds in London can always be bought or sold for $4.8665 per pound. To reduce the case to a unit basis, suppose that you owed one pound in London, and that, finding it difficult to buy a draft to send in payment, you elected to send actual gold. The amount of gold necessary to settle your debt would cost $4.8665, in addition to which you would have to pay all the expenses of remitting. It would be cheaper, therefore, to pay considerably more than $4.8665 for a one-pound draft, and you would probably bid up until somebody consented to sell you the draft you wanted. Which goes to show that the mint par is not what governs the price at which drafts in pounds sterling can be bought, but that demand and supply are the controlling factors. There are exporters who have been shipping merchandise and selling foreign exchange against the shipments all their lives who have never even heard of a mint par of exchange. All they know is, that when exports are running large and bills in great quantity are being offered, bankers are willing to pay them only low rates--$4.83 or $4.84, perhaps, for the commercial bills they want to sell for dollars. Conversely, when exports are running light and bills drawn against shipments are scarce, bankers may be willing to pay 4.87 or 4.88 for them. For a clear understanding of the mechanics of the exchange market there is necessary a clear understanding of what the various forms of obligations are which bring foreign exchange into existence. Practically all bills originate from one of the following causes: 1. Merchandise has been shipped and the shipper draws his draft on the buyer or on a bank abroad designated by him. 2. Securities have been sold abroad and the seller is drawing on the buyer for the purchase price. 3. Foreign money is being loaned in this market, the operation necessitating the drawing of drafts on the lender. 4. Finance-bills are being drawn, _i.e._, a banker abroad is allowing a banker here to draw on him in pounds sterling at 60 or 90 days' sight in order that the drawer of the drafts may sell them (for dollars) and use the proceeds until the drafts come due and have to be paid. 1. Looking at these sources of supply in the order in which they are given, it is apparent, first, what a vast amount of foreign exchange originates from the direct export of merchandise from this country. Exports for the period given below have been as follows: 1913 $2,465,884,000 1912 2,204,322,000 1911 2,049,320,000 1910 1,744,984,000 1909 1,663,011,000
