The Reserve Bank of India gave too long a rope to the Yes Bank promoters and management. It finally acted with a totally avoidable blunt tool of moratorium on withdrawals by hapless depositors and created a mayhem in the banking and financial sector. The biggest casualty has been the trust of depositors in the country's banking system. The impact of this mistrust would be felt most by the small private sector banks while the public sector lenders have this umbrella of ''government'' behind them, although legally speaking, there is no protection for depositors except the deposit insurance up to Rs 5 lakh per account.
