How did trade and economics contribute to americas entry into world war 1

Until April 6th, 1917, America was still a declared neutral state and she had tried to keep out of World War 1. However, she had economic relationships with nations involved in the war such as loans and financial support. American Secretary of State William Jennings opposed this financial support of warring nations, arguing that refusing to loan to any Allied nations in Europe would help to accelerate the end of the war. Even though President Wilson agreed at first, he retreated this when France argued that if it was not legal to take out credits from America, then it was not legal to buy American goods as well.  

Regarding this, the American steel industry had faced declining profits during the Recession of 1913–1914. And when the war began in Europe, the increased demand for tools of war began a period of intensified productivity that relieved many U.S. industrial companies.
