In 1914 the United States, for all its industrial power, played a limited albeit expanding role in world economic affairs. It remained a debtor nation, dependent on Great Britain in particular as a source of capital. Britain and Germany as well had a greater share of international trade, and the two still dominated the markets of Latin America.

With Americans making few purchases from a war-torn Europe, the United States soon transformed itself from a debtor into a creditor nation, taking up the duties and privileges of lender to the world.
