Deposit rate on savings accounts: To deregulate or not?

The interest rate on savings bank deposits in India has been at 3.5% since March 2003, before which it was at 4%). In April 2010, the Reserve Bank of India (RBI) had changed the methodology of interest calculation on savings deposits to an average daily basis. For banks, this has effectively increased the savings deposit cost by 50-100 basis points (bps) and overall deposit cost by 10-25 bps. While interest calculation on average daily basis has led to higher earnings on savings deposits for deposit holders, the inflation-adjusted return continues to be negative. Against the 3.5% rate on savings deposits, the average inflation rate in India has been around 5.3% in the last decade, around 5.5% over financial years 2005-10 and around 6.5% over fiscal 2008-11. On multiple occasions, the RBI has expressed its intention to deregulate the savings bank deposit rate and is likely to float a discussion paper on this topic.
