India should double the limit for bank deposits that are insured, to at least Rs 2 lakh. That would still be short of a rule of thumb, of the ceiling being double the per-capita GDP. The other rule of thumb, as former SBI economist MR Das explained on this page on Tuesday, is that the limit should cover 80% of depositors and at least 20% of the deposits. This is less relevant for India. The Rs 1 lakh limit, estimates Das, cover 92% of depositors, thanks to the huge increase in the number of small account holders, following financial inclusion drives.
