Underlying the whole business of foreign exchange is the way in which obligations between creditors in one country and debtors in another have come to be settled—by having the creditor draw a draft directly upon the debtor or upon some bank designated by him. A merchant in New York has sold a bill of goods to a merchant in London, having thus become his creditor, say, for $5,000. To get his money, the merchant in New York will, in the great majority of cases, draw a sterling draft upon the debtor in London for a little over £1,000.
