All United States gold is kept at Fort Knox, at the New York Assay Office, or at the various mints; the gold deposited at the Federal Reserve Bank belongs to some seventy other countries—the largest depositors being European—which find it convenient to store a good part of their gold reserves there. Originally, most of them put gold there for safekeeping during the Second World War. After the war, the European nations—with the exception of France—not only left it in New York but greatly increased its quantity as their economies recovered.
