1) although as per your agreement bank can charge prepayment charges it is contrary to RBI circular which prohibits levy of any prepayment charges
2)
Master Circular on Customer Service in Banks, issued by Reserve Bank of India. There is a specific provision made in the said circular in para 6 which deals with levy of service charges. Para 6.1 of the circular reads as follows:--
"6.1 Fixing service charges by banks The practice of IBA fixing the benchmark service charges on behalf of member banks has been done away with and the decision to prescribe service charges has been left to individual banks. While fixing service charges for various types of services like charges for cheque collection, etc., banks should ensure that the charges are reasonable and are not out of line with the average cost of providing these services. Banks should also take care to ensure that customers with low volume of activities are not penalised.
Banks should make arrangements for working out charges with prior approval of their Boards of Directors as recommended above and operationalise them in their branches as early as possible."
As per para 6.4 of the Circular, which deals with levy of foreclosure charges/ pre-payment penalty on floating rate term loans, it has been laid that banks will not be permitted to charge foreclosure charges/ pre- payment penalties on all floating rate term loans sanctioned to individual borrowers. In para 6.6 of the Circular, an advice has been given to the bank to follow a uniform, fair and transparent pricing policy and not discriminate between their customers at home branch and non-home branches.
