Many banks offer gold accounts where gold can be instantly bought or sold just like any foreign currency on a fractional reserve basis. Swiss banks offer similar service on a fully allocated basis. Pool accounts, such as those offered by some providers, facilitate highly liquid but unallocated claims on gold owned by the company. Digital gold currency systems operate like pool accounts and additionally allow the direct transfer of fungible gold between members of the service. Other operators, by contrast, allows clients to create a bailment on allocated (non-fungible) gold, which becomes the legal property of the buyer.
