Banking Supervision Track XBRL-based Basel II Reporting System: Experience of Reserve Bank of India A S Ramasastri & P R Ravimohan June 24, 2009
First Three Steps The Basel II Path Fast Track XBRL Future Roadmap
About 20 departments of Reserve Bank of India receive data at about 20 locations from about 200 commercial banks with about 70000 branches Templates for reporting, called returns, which are around 250 as on date Varying degrees of technology levels across banks Attempts to rationalize the returns and to streamline multiple modes of data submission resulted in the origin of Online Return Filing System (ORFS)
An important fortnightly return called Form A has been brought under ORFS It has been designed and developed using XML tags – to be in readiness for adopting XBRL Based on the experience, the system has been extended to another 50 returns To standardize the data elements across returns and to be in line with international practices, XBRL was considered
The Governor formed a High Level Steering Committee with the Deputy Governor as Chairperson to implement XBRL-based data reporting by banks After a pilot study and feasibility analysis, the Committee mandated implementation of the newly introduced Basel II reporting system under XBRL Basel II implementation is a simultaneous journey, going parallel
India has been adopting international best practices in the area of banking regulation in a well calibrated manner which is suitable to requirements of the financial system Reserve Bank of India has emphasized on strengthening of regulation on capital adequacy as a key parameter in promoting financial stability
India adopted Basel I in a phased manner from 1992 onwards India stipulated the capital to risk weighted asset ratio of 9.0 % as against international norms of 8% and a Tier I capital ratio of 6%.
Capital charge for market risk in line with market risk amendment of 1996 to the Basel I accord was adopted in 2005.

Implementation of Basel II in India has been in a phased and calibrated manner All commercial banks in India have migrated to Basel II as on March 31, 2009 To begin with, India has adopted the basic / standardised approaches of Basel II.
RBI has also been preparing simultaneously for introducing advanced approaches for those banks which have sophisticated risk management structure

Pillar 1 Minimum Capital Requirement Pillar 2 Supervisory Review Pillar 3 Market Discipline Capital for Credit Risk ( SA ; FIRB; AIRB) Capital for Market Risk (SMA; SDA ; IMA) ( Capital for Operational Risk BIA ; SA; AMA)
The current global financial turmoil has brought to sharp focus the role of capital regulations in promoting financial stability and mitigating procyclicality Capital should serve as an effective buffer to absorb losses over the cycle, so as to protect both the solvency of financial institutions in the event of losses, and their ability to lend.
The recent London Summit by G 20 has articulated certain action points on capital regulation G20 Leaders should support the progressive adoption of the Basel II capital framework, which will continue to be improved on an ongoing basis, across the G20.
In this context, the BCBS should develop standards to promote the build-up of capital buffers in good times that can be drawn down in periods of stress. The BCBS should also complement risk-based capital measures with simpler indicators to monitor the build-up of leverage. The international standard for the minimum level of capital should remain unchanged until the financial system has recovered.
Underestimation of risk and the consequential underpricing of risk are attributed as major factors for the present crisis.
Since Basel II attempts to build a more risk sensitive framework for capital regulation it is essential that the information flow is designed to be timely and accurate
The implementation of Basel II has thrown up several challenges due to its requirement of timely receipt of information from banks in a standardised and transparent format and at the disaggregated level.
One of the challenges is upgradation of bank-wide information system through better branch connectivity within banks and then integrating this with the regulatory reporting Under Pillar II of Basel II, RBI has to ensure that banks assess accurately all the risks they are exposed to and accurately determine the capital they need to have in commensurate with their risk profile
Under Pillar III (Market Discipline) of Basel II suitable disclosures have to be made by the banks so as to enable the market participants to take informed decisions RBI has been monitoring banks’ exposure to certain sensitive sectors with a view to ensuring prescription of appropriate risk weight RBI has been in a calibrated manner revising risk weights and provisioning relating to sensitive sectors with the objective of ensuring asset growth with minimum volatility.
Basel II implementation thus requires quicker, quantitative and qualitative analysis of financial information by the regulator so that banks can be monitored closely vis-a-vis Basel II guidelines and certain corrective policy measures be taken These requirements of efficient, standardised and transparent reporting system which facilitates accurate and reliable extraction of data led RBI to introduce XBRL reporting system for Basel II reports from banks
The Basel II framework also offers multiple options of increasing sophistication for computing capital requirements for the three major categories of risks.
While for the present, banks are required to adopt the relatively simpler approaches available under the framework, RBI may permit few banks to migrate to advanced approaches A draft time frame for the purpose has been drawn up Implementation of advanced approaches would require tremendous data processing at the bank level and RBI
The requirement of maintaining long time series data, processing it and modelling several variables would throw up several issues of reporting within the banks The requirement of assessing the data quality of the banks and validating the models of the banks will be dependent on real time and seamless information flow between banks and RBI. The XBRL project would be critical in this regard.
High Level Steering Committee Involvement of banks Interaction with international institutions – Europe, Japan, Australia Learning from best practices in other central banks – Bank of Spain Working closely with external consultants Moving the other stakeholders in India
As directed by the High Level Steering Committee, the Capital Adequacy Return (RCA 2), based on the Basel II norms has been taken up first A 2- stage approach An Excel Based Report preparation Tool A web portal for Submission of Returns by the Banks Viewing Bank Returns and MIS Reports by RBI A Dimensional XBRL Taxonomy sits on top of both these applications

At RBI’s end, following facilities/advantages : ◦ generating standard and ad-hoc reports as required ◦ maximum possible automation of processes ◦ more analysis facilitated since less of data related issues expected ◦ ◦ ◦ ◦ ◦ ease of incorporating data for various analytical studies and periodic reports Quicker access to bank analysts and inspection officials Provision for automated signalling of “red flags” in submitted data which would need further analysis Access of the centralized data repository by other departments like banking policy department, monetary policy department, financial markets department etc. as required Use of business intelligence tool for advanced analytics and drill down/roll up facility 31
Phased Approach In Phase I, Basel II reporting implemented International Seminar coinciding with launch Sec 42 Return under ORFS being brought to XBRL standards Taxonomies for Annual Accounts being developed
Institute of Chartered Accountants of India (ICAI) has been working towards ◦ ◦ Formation of XBRL-India jurisdiction Development of Taxonomies Taxonomies for C&I already developed – yet to be implemented Banking taxonomies getting developed RBI and ICAI are working closely
Industry-based classification ◦ ◦ ◦ Commercial and Industrial companies Banking companies Non-Banking Financial companies Core Schema ◦ Exhaustive list of all element declarations ◦ Common elements defined once Distinct extended links for each industry
◦ Designing general banking taxonomy in accordance with the C&I taxonomy ◦ ◦ Based on IFRS 2006 No dimensions RBI can use the banking taxonomy and extend it to include dimensional structure FINREP structure
Release date Modularity Structure Elements Dimension Vs. Tuples IFRS 2006 15 th August 2006 The files (Schema and linkbases) are located in one folder.
There was a common entry point, wherein the users had to select and browse the taxonomy. i) 4100 (approx) ii) Elements outside the IAS and IFRS (common practices and industry specific) are included in the taxonomy Tuples are used in the taxonomy IFRS 2008 24 th June 2008 The files are organized based on the IAS and IFRS. There is a core schema containing all the elements defined, and linkages to the different folders for every IAS and IFRS. The entry point is entity specific and hence has to be created by the user of the taxonomy.
i) 2700 (approx) ii) Elements only from the IAS and IFRS are part of taxonomy Dimensions have been included in the taxonomy
Notes to accounts information is largely tabular and therefore is Multi-dimensional data Data points having similar attributes IFRS 2006 – Does not use dimension IFRS 2008 – Includes dimensions
