Dear Sir,
Implementation of the Advanced Measurement Approach (AMA)
for Calculation of Capital Charge for Operational Risk
Please refer to our circular DBOD.No.BP.BC.23/21.06.001/2009-10 dated July 7,
2009, inter alia advising banks that they can apply for migrating to Advanced
Measurement Approach (AMA) for calculation of capital charge for Operational
Risk from April 1, 2012 onwards.
- The Basel II Framework presents three methods for calculating operational
risk capital charge in a continuum of increasing sophistication and risk
sensitivity:
- the Basic Indicator Approach (BIA);
- the Standardised Approach (TSA)/ Alternative Standardised Approach (ASA); and
- Advanced Measurement Approaches (AMA).
- The guidelines for calculating operational risk capital charge for BIA and
TSA/ASA have been issued separately. The guidelines on AMA for computing capital
charge for operational risk are annexed. The various aspects of the guidance vis-a-vis the form in which they find place in Basel II Framework, have been
elaborated upon in order to provide a comprehensive background to important
concepts used in measurement and management of operational risk.
- This guidance is in addition to that contained in 'Guidance Note on
Management of Operational Risk' issued by RBI vide its circular
DBOD.No.BP.BC.39/21.04.118/2004-05 dated October 14, 2005 and wherever there is
conflict between the two, the guidance contained in this circular would prevail.
- Banks intending to migrate to AMA for computing capital charge for
operational risk are advised to assess their preparedness with reference to
these guidelines. As and when they are ready for introduction of AMA, they may
first give Reserve Bank of India (RBI) (Chief General Manager-in-Charge, Reserve
Bank of India, Department of Banking Operations & Development, Central Office,
12th Floor, Shahid Bhagat Singh Road, Mumbai - 400001), a notice of intention.
RBI will first make a preliminary assessment of the bank’s risk management
system and its modeling process. If the result of this preliminary assessment is
satisfactory, RBI will allow the bank to make a formal application for migrating
to AMA. RBI will then perform a detailed analysis of the bank's risk management
system and proposed model prior to according approval.
- It may be reiterated that banks would have the discretion to adopt AMA, while
continuing with simpler approaches for computation of capital for credit and
market risks. Further, a bank following BIA can switch over to the AMA directly.
However, as banks are aware, all the qualitative requirements relating to
operational risk management applicable to TSA form part of the qualitative
requirements for AMA. Therefore, a bank may also consider moving to TSA first so
that the work done in the implementation of TSA could be used to meet part of
the requirements for AMA as and when the bank considers switching over to that
approach.
Yours faithfully,
(B. Mahapatra)
Chief General Manager-in-Charge
