An unallocated bullion account is a bank account opened not in a currency but in a bullion. As a rule, unallocated bullion accounts (UBAs) are opened in gold, silver, platinum or palladium, and display the amount of bullions belonging to the account holder in grams without individual signs – samples, forms, number of bullions, etc. (BML Markets)
