To create a FD at any bank, do you have to compulsorily open a savings a/c first?

Most of the banks allow if it’s high value fd

They have to open FD irrespective of SB a/c.

its better to open an SB acc with linked FD. AMB can be negotiated to zero & dont take debit card & disable sms alerts to avoid fees.

Check your main post office FD schemes as well.
