Update:
Attached is the latest Private banking proposition, if it helps.
As per their latest terms & conditions, Wealth Management is 25L to 50L TRV.
Wealth Select is merged into Private banking. There is no separate Wealth Select segment.
Private banking starts at 50L TRV and within 1-2 years, they expect you to be at 2cr TRV. (Not mandatory though)
Everything under ICICI umbrella is counted under TRV - personal demat with ICICI and direct mutual fund investments included.
