What is the list of all private banks in Hong Kong please?

Private banks are banks that are not incorporated. A non-incorporated bank is owned by either an individual or a general partner(s) with limited partner(s). In any such case, the creditors can look to both the "entirety of the bank's assets" as well as the entirety of the sole-proprietor's/general-partners' assets.

Some private banks in HK:
BNP Paribas Private Bank
EFG Private Bank SA
HSBC Private Bank (Suisse) SA

Local representative office:
