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.
