I have been a HSBC Premier customer for just under 2 years and overall have been quite satisfied. Here are the positives as I see them:

1. Got a Kindle for signing up and depositing $50K
2. Opened a brokerage account and was able to buy US corporate bonds at a lower price than I could at either Schwab or TD Ameritrade
3. I save transaction fees every month since I do regular transfers to a foreign bank account
4. While traveling abroad, I am able to use the HSBC Premier Credit card with no foreign exchange charges
5. I opened a business account recently and have been able to do international wire transfers for a fee of $15 (compared to $30-$50 at other banks)
6. The Rewards program is decent with a $400 ticket available for 24000 points (approx. 1.67 cents per dollar spent). Of course, you can get value of up to 2 cents per dollar spent with the Capital One Venture card - but I was OK with this.

Overall, I find it convenient to do business with a global bank that is present internationally in most (if not all) of the countries that I travel to and do business in.

Would love to get other opinions.
