But if you have both Premier accounts in Canada and Hong Kong, you can transfer at no cost and no commissions between the accounts. Once your CDN in Hong Kong was transferred to Canada, you can get CDN from your Canadian account without worrying the commission and exchange rate.
Let's do the arithmetic. How many Hong Kong to Canada transfers would you do in a year? Two max? Without Premier you would pay about $150 per year in transfer fees, so Premier would save you $150.
After the transfer to Canada, though, you don't need the advantage of commission-free ATM withdrawals that Premier gives you around the world, since you're using your local HSBC account in Canada.
So far, Premier appears to have saved you $150 per year, yet you're forced to meet the minimum balance of (say) $100,000 CDN in both your Canada and Hong Kong Premier accounts. This means that $200,000 CDN of you money cannot be invested elsewhere to greater advantage (HSBC's does not have a stock trading department).
If you earned (say) 5% on your stock trading elsewhere, less capital gains tax, you'd keep about $7500. If you invested the $200,000 in your two Premier accounts in a flexible bond (that allows redemptions for those bank transfers we talked about), you'd get maybe 3%, although probably less. But let's say 3%. Less taxes, you'd keep about $3,000.
So, you'd be sacrificing stock-investment income of $7500 in order to have Premier, and therefore have to accept bond income of $3,000. With the Premier option, you're behind by $3500 ($7500 - $3000).
And if you were to fall below the Premier minimum balance, the penalty is about $50 per month!!
All this to save about $150 in bank transfer fees. Doesn't make financial sense to me.
