Bank Audit

Banks are the foundation of our economy. They handle a huge amount of deposits and savings of the public, so they have to be closely monitored and reviewed. A bank audit is one important process of this monitoring.

‘Audit’ or ‘Auditing’ refers to an activity that is carried out by any business entity on its own or to fulfil the compulsion laid under any law to evaluate the transactions, accounts and documents of the business and to confirm its accuracy and legitimacy. This examination is conducted by internal or external auditors.


Bank Audit can be divided into three categories viz.

  • Concurrent Audit
  • Internal Audit or Information Systems Audit
  • Statutory Audit

This averts accumulation of irregularities which becomes a big trouble for any branch at the time of end audit. Concurrent Auditors keep a check on daily maximum cash balance adherence, KYC norms, documentation related to disbursement of loan and loan disbursement in consonance with rules & regulations, income leakage etc. Such details are furnished in the ‘concurrent audit report’.
