i was able to open the account without any initial funding ( i have 3 ICICI CCs with 4L limit )
The thing is that , the RM that was assigned to me and that helped opened the account said that they can open this for free however for their target and help they wanted me to transfer 1L and hold it for approx 5 days.
I agreed to help and removed the entire amount after 5 days.
No issues whatsoever.
The RM kept trying for investments and for me to put funds in the account and i flat out refused citing its a 0 balance account and not to ask me this again. Never heard from him regarding this again.
All in all, it is possible to open with absolute 0 investment but you will have to find the right person at the branch willing to do it.
