<h1>Basic Savings Bank Deposit accounts must provide prescribed minimum facilities free and may be converted only on written request.</h1> Reserve Bank of India mandates that Basic Savings Bank Deposit (BSBD) accounts must provide specified basic facilities free of charge without any minimum balance requirement, including cash deposits, electronic credits, government cheque collections, unrestricted deposits, at least four withdrawals monthly and an ATM or ATM cum Debit Card. Banks may offer optional value added services with non discriminatory pricing and disclosure, but such services cannot be made conditional on maintaining a minimum balance nor change the BSBD status. Conversion to a regular savings account requires the customer's written request, and RBI may penalise banks for non-compliance under the Banking Regulation Act.
