to open a HSBC Premier (卓越理財) account, you should have $1,000,000 asset in HSBC, can be in your MPF & investment account.
after you opened the account and you fail to maintain the balance of $1,000,000, there will be monthly service fee of $40. if you fail to maintain the balance of $500,000, then monthly service fee will become $340
I have a 運籌理財 account with HSBC, the altogether balance is about 600,000. They send me an invitation to change it to 卓越理財戶口, but since below 1mil you have to pay fee, so I did not change it.
