Many types of gold "accounts" are available. Different accounts impose varying types of intermediation between the client and their gold. One of the most important differences between accounts is whether the gold is held on an allocated (fully reserved) or unallocated (pooled) basis. Unallocated gold accounts are a form of fractional reserve banking and do not guarantee an equal exchange for metal in the event of a run on the issuer's gold on deposit. Another major difference is the strength of the account holder's claim on the gold, in the event that the account administrator faces gold-denominated liabilities (due to a short or naked short position in gold for example), asset forfeiture, or bankruptcy.
