Private client isn’t private bank. They name is like that so you think it is though. :) private banking services start around $10 to $15M with higher tiers as you go.
(Not trying to diminish private client services. But they’re night and day different services.)
The non retail banks that have a good reputation are even higher.
They don’t outwardly advertise their minimums because “it depends.” For example if you’re an up and comer in your field where it seems like you’re LIKELY to one day hit the mins, they’ll start the relationship early.
Private banking is basically the bank providing family office services. They generally give you one contact person, that makes your money annoyances non-annoyances. You need a loan for something, they just go sweet talk everyone involved to make the loan happen for you.
They also invite you to all the bank's private events, so you can schmooze with other high net worth people. Banks are always sponsoring fancy events everywhere, and private banking clients generally get free invites.
