SBI and HDFC Bank which are the 2 of the largest banks in the country have protested against the RBI proposal to free up the interest rate given on savings account in India.Note RBI fixes the rate at which money deposited in saings account earns interest currently for all banks in India.The current rate is 3.5% which is way below the near double digit inflation rate being experienced in India.Most Indians deposit their savings in bank saving and fixed deposit accounts as there is no widespread equity or debt investment culture in the country.This allows banks with a large retail depositer base to earn supernormal profits by paying pathetic interest rates on savings account and lending that money at 12-13%.While the public sector banks have to serve a lot of priority sectors private banks have no such concerns.This leads to high NIM for private banks leading to huge profit growth each year.This has made investing in top banks in India such an attractive proposition.
