The Federal Reserve Bank of New York is one of the 12 Federal Reserve Banks of the United States. responsible for the Second District of the Federal Reserve System, which encompasses New York state, the 12 northern counties of New Jersey, Fairfield County in Connecticut, Puerto Rico, and the U.S. Virgin Islands. A public competition for design of the building was held and the architectural firm of York and Sawyer submitted the winning design. The bank moved to its current location in 1924. The Federal Reserve Bank of New York maintains a vault that lies 80 feet (24 m) below street level and 50 feet (15 m) below sea level, resting on Manhattan bedrock. By 1927, the vault contained 10% of the world's official gold reserves. Currently, it is reputedly the largest gold repository in the world (though this cannot be confirmed as Swiss banks do not report their gold stocks) and holds approximately 7,000 tonnes (7,700 short tons) of gold bullion ($415 billion as of October 2011), more than Fort Knox.
