@Ashish KS Presently, there is no single account (savings/FD/any other) that caters to the entire family for IPO purposes, that I know of.
Who knows, in future we will have !
And as for terms like too much, too little, more, less, ots of money ... these are all relative and subjective. For a family of four, if 4 bHNI applications are to be put, one needs at least Rs 40L and many a times there are multiple issues simultaneously !
@CASuraj You are right about interest portion, such banks do have their t&c applied statements. But, even if effective interest rate is say 5 to 6%, it is way better. Besides, it is also true that earning interest is not the prime aim - if one has IPOs to apply for .
Anyways, not promoting any banks or their policises here - one should study and choose what suits best !
