@BIGGYBULL I have a Kotak saving account (zero balance allowed).
I have kept funds upto 1 hni in saving account and rest funds are part of (manually created) F. Once FD is created, I link the FD with my Saving account. The funds of linked FD can be used for applying IPO and other reason as well. This is also called Sweep-in facility.
Suppose there is a debit transaction of 60k via cheque or UPI transaction and your balance is less than 60k then the last created FD breaks automatically.
Regarding Active Money, you can finds details at https://www.kotak.com/en/stories-in-focus/accounts-deposits/savings-account/activmoney-savings-account-vs-traditional-savings-accounts-which-is-right-for-you.html#:~:text=Kotak%20ActivMoney%20vs%20Traditional%20Savings%20Accounts&text=The%20Kotak%20ActivMoney%20account%20is,work%20earning%20FD%2Dlevel%20interest.
Hope this helps
🙏
