Banks should also not levy penal charges if the minimum balance is not kept in any inoperative account, he added.
State Bank of India does not levy any charge for non-maintenance of a minimum balance in basic savings account.
Customers of ICICI Bank and HDFC Bank are charged Rs 750 per quarter if they don't maintain a minimum average quarterly balance of Rs 10,000 in urban centres and Rs 5,000 in semi-urban areas.
The liability of customers should be limited in electronic banking transactions in cases where banks are not able to prove customer negligence, he added.
Highlighting that consumer protection is an integral aspect of financial inclusion, Rajan said the RBI proposes to frame comprehensive consumer protection regulations based on domestic experiences and global best practices.
"In the interest of their consumers, banks should consider allowing their borrowers the possibility of prepaying floating rate term loans without any penalty," he added.
