Where Private bank is genuinely good

  • One relationship for banking, lending and investing
  • A named adviser and a physical branch
  • Everything administered for you, including reporting

Where it costs you

  • The most expensive option in this comparison by a wide margin
  • Fees are charged on the whole portfolio every single year
  • In-house products are often recommended and carry their own fees

My take

The most reassuring account on the list and by far the most expensive: USD 45,000 against USD 614 for the very same portfolio.

Both accounts are legitimate and both are regulated. The question is what you are paying for. If you want a hand-held experience in your own language and time zone, Private bank does that. If you want to keep as much of your return as possible, Interactive Brokers is the cheaper account and the extra paperwork takes about half an hour a year.
