Much of the gold in the vault arrived during and after World War II as many countries wanted to store their gold reserves in a safe location. Holdings in the gold vault continued to increase and peaked in 1973, shortly after the United States suspended convertibility of dollars into gold for foreign governments. At its peak, the vault contained over 12,000 tons of monetary gold. Since that time, gold deposit and withdrawal activity has slowed and the vault has experienced a gradual but steady decline in overall holdings. However, the vault today remains the world’s largest known depository of monetary gold.
As of 2012, the vault housed approximately 530,000 gold bars, with a combined weight of approximately 6,700 tons. The vault is able to support this weight because it rests on the bedrock of Manhattan Island, 80 feet below street level and 50 feet below sea level.
Gold bars are transported by elevator from street level to the vault’s basement location. Once inside the vault the bars become the responsibility of a control group consisting of three representatives: two members of the New York Fed gold vault staff and one member from the New York Fed internal audit staff. These three individuals must be present whenever gold is moved or a compartment is opened in the vault—even to change a light bulb. This helps ensure proper safekeeping and maximum security for the gold.
All bars brought into the vault for deposit are carefully weighed, and the refiner and fineness (purity) markings on the bars are inspected to ensure they agree with the depositor instructions and recorded in the New York Fed’s records. This step is vital because the New York Fed returns the exact bars deposited by the account holder upon withdrawal—gold deposits are not considered fungible.
Following the verification process, the gold is moved to one of the vault’s 122 compartments, where each compartment contains gold held by a single account holder (meaning that gold is not commingled between account holders). In rare cases, small deposits are placed on separately numbered spaces on shelves in a “library” compartment shared by several account holders. Each compartment is secured by a padlock, two combination locks and an auditor’s seal. Compartments are numbered rather than named to maintain confidentiality of the account holders.
The New York Fed charges account holders a handling fee for gold transactions, including when gold enters or leaves the vault or ownership transfers (moves between compartments), but otherwise does not charge fees for gold storage.
