It was expected to submit its report by the end of July 2006.RBI is working on prudent charges for various services amidst concerns from Members of Parliament that foreign banks were practising "hidden" policy of denying credit cards and loans to police, politicians and advocates.Taking note of this, Finance Minister P Chidambaram told the Rajya Sabha recently that the issue will come under RBI scrutiny and strong action will be taken against them for violating the code of banking practice.
