Demystifying Revised Credit Risk Standardized Approach

Credit Risk is one of the major traditional risk that is actively managed by Banks across geographies .With Changing times the Credit Risk Regulations too have undergone tremendous changes .Regulations such as Basel I bought in some standardization in which credit risk was measured and reported, as times progressed and the framework matured regulations such as Basel II and Basel III saw a more risk sensitive approach towards measuring credit Risk. Post the Financial Crisis, Global regulators started issuing many regulations to contain and control various risk types. As the regulatory agenda has nearly firmed we see a focused rigor from regulatory bodies  to ensure standardization and comparability across numbers that are reported by Banks for various risk types ,in line with the thought process we are a seeing many new regulations and also enhancements to existing frameworks which are trying to attempt this .In 2015 ,Bank for international settlement (BIS)  came up with a revised standardized approach for credit risk as a successor to existing Basel III Credit Risk framework .Since then through various consultations this standard has undergone numerous changes and is finally zeroing in on an  implementation date of Jan 2022.

If we were to get in to basics of credit Risk, It emanates when bank accepts deposits from its depositors and lends the same to its customers who can be sovereigns, corporates or retail customers. This activity creates an exposure for the Banks which can result in a potential loss if the borrower is unable to repay the debt in full or in part.

The image below provides a summarized view of how the Basel Risk Framework has evolved till date


The revised Standardized approach for credit risk was introduced with the following main objectives

  • Reduced Dependency on external ratings agencies – External Rating agency plays a critical role in determining credit risk of the counterparty. Mechanical reliance on external ratings without any due diligence will lead to non- prudent risk management. By introducing the due diligence process bank has reduced dependency on External rating agencies
  • Increased comparability across banks and jurisdictions:Though there are several implementation options at regulator’s discretion, the new standards will considerably aid in comparability between Banks and Jurisdictions.
  • More focus on risk sensitivity& granularity – The revisions introduce newer asset classes and additional credit risk assessment within the framework, which will help in arriving at more prudent estimates of RWA and regulatory capital
  • Dynamic Risk Weights –The Risk Weights as prescribed in current standardized approach are in line with the current economic conditions.

This approach sees introduction of two approaches namely

  • External Credit Risk Assessment Approach (ECRA) – ECRA is applicable for rated exposures of banks in jurisdiction that allow use of External Ratings for regulatory purposes. Banks adopting this approach will also have to set up a Due Diligence framework to assess the rating applicability
  • Standardized Credit Risk Assessment Approach (SCRA) – SCRA is applicable for countries where external ratings are not permitted, banks would classify exposures into three buckets (A, B and C) based on assessment of borrowers’ ability to pay and derive RWA accordingly 

In terms of implementation, the Revised approach will have an impact on the below dimensions

  • Capital requirements- likely to increase for banks of varying sizes due to additional due diligence requirements and conservatism. 
  • Data and Reporting– The revised guide line will require Additional data elements to be sourced and newer Data interfaces to be established along with adequate Quality Controls for computational as well as reporting needs. Due Diligence requirements will also require vast amount of Data for Banks which are following the ECRA approach. 
  • Computations – Rules for RWA computation would depend on the approach followed in each country rather than directly external rating. The below table provides a summary of impact of
Exposure ClassCurrent Standardized Approach


Revised Standardized Approach
SovereignsMapping to external agency ratings and Export Credit Agency (ECA) scores and assign RWNo Change. current Approach is continued
Public Sector EntitiesMapping to external agency ratings and Export Credit Agency (ECA) scores and assign RWOne category less favorable risk bucket than sovereigns. Mapping to external agency ratings and Export Credit Agency (ECA) scores and assign RW
Multilateral Development Banks (MDBs)Basic differentiation between the MDBs that have high-quality long term issuer ratings and other short term issuer ratingDue diligence of MDB counterparty is required along with existing approach


One category less favorable risk bucket than sovereigns (long-term and short-term claim distinction) or credit assessment of banksIntroduced 2 approaches:

ECRA: where national supervisor allows banks to use External ratings.

SCRA: for rest of the banks and for unrated exposures. Grade Based on Minimum Capital requirement along with Buffer capital.

Banks to carry out Due diligence of the customer credit worthiness. Outcome of due diligence factor should be considered while applying RW

CorporatesMapping to external rating agency and assign RW. Also at  national  discretion,  supervisory  authorities  may  permit   corporate  claims  to receive  100%  Risk Weights without  regard  to  external  rating.Bank has two options:

Ø  Where national supervisor allows banks to use External ratings, apply base RW based on rating

Ø  Else apply 100% RW if corporate is not Investment grade or Corp

Specialized LendingNo separate treatment from the corporate exposuresExposure is Classified into 3 categories

1.      Project Finance

2.      Object Finance

3.      Commodity finance

Where national supervisor allows banks to use issue specific external ratings, apply base RW based on rating

Else apply 100% RW for Object and commodity finance and 130% for Project Finance during pre-operational period and 100% during operation period

Subordinated Debt, Equity and Capital InstrumentsInvestments  in  equity  or  regulatory  capital instruments issued by banks or securities firms is risk weighted at 100%Ø  For speculative unlisted company RW 400%

Ø  For Other Equity holding RW = 250%

Ø  For subordinated debt and capital instruments other than equities RW 150%

Retail ExposuresRisk-weighted at 75%, except for pastduesDifferentiation between the

Regulatory Retail (75% Risk Weight)

and Other Retail (100% Risk Weight) exposures

Residential Real Estate35% Risk WeightLTV Ratios and the characteristics of repayment (if materially dependent on cash flows generated by property) are considered for deriving RW.
Commercial Real Estate100% Risk Weight as per BaselLTV Ratios and the characteristics of repayment (if materially dependent on cash flows generated by property) are considered for deriving RW.

 Challenges in implementing Revised Standards:The revised standards will also bring in below challenges for the Banks –

  • Complexity and granularity of regulation requirement will increase extensive implementation effort
  • Revised approach involves extensive data requirement such as data on residential and commercial real estate collateral etc.,
  • Banks and financial institutions applying the ECRA approach have to introduce new due-diligence framework for assessing the counterparty credit worthiness independent of using external rating agency data.
  • Need to re-align the business model and strategies as the revised approach will potentially result in an increase in RWA and capital requirements

The Revised standards will also have Cross Program impacts especially with initiatives around Default Management and Pillar III disclosures. Also many Banks have already started initiatives to focus on the revised standards so that they are better prepared to comply with the Jan 22 deadline and are also using Traditional Technologies as well as newer Digital technologies (like AI,ML & RPA etc.)   to overcome the implementation challenges.
