The dollar glut is a term for the accumulation of American dollars outside of the United States as a reserve currency, contrasted with the dollar gap, which led to the creation of the Marshall Plan following World War II. The eventual shift to a dollar glut forced the end of the gold standard in the United States and led to the collapse of the Bretton Woods system.
