Almost all Hong Kong bank accounts are multi-currency, with only a few exceptions. This means that you can view separate balances for each currency when you access your account via Internet banking, even though you have just one account number.
For instance, you can hold a variety of currencies such as HK dollars, Singapore dollars, US dollars, Euros, and also the Chinese Yuan Renminbi, as well as virtual ounces of gold in your multi-currency HK bank account.
