2. An Overview



The purpose of the Basel III Reforms published by the Basel Committee on Banking Supervision (BCBS) in December 2017 – a package of reforms commonly known as ‘Basel IV’ – is to provide confidence in the banking system by improving the comparability of banks’ capital ratios.


From a credit risk perspective, this is primarily to be achieved by the implementation of an output floor – designed to reduce the variation in RWAs across banks resulting from their internal models.


  • Mandatory implementation of revised standardised approach

  • Reduce reliance on external ratings

  • Changes to methodology to remove the option to use A-IRB

  • Application of regulatory minimum input levels (e.g. PD)

  • *The 5-year phase in period, originally due to start in 2022, will be revised following the global COVID-19 pandemic

3. First Steps


  • Calculate a high-level estimate of future capital requirements on an asset class basis to prepare your organisation for future capital needs.

  • Map existing processes and outputs to new regulatory reporting/ QIS formats to automate these processes and reduce reliance on already constraint resources during a period of dual reporting.

  • Perform a gap analysis of data required to implement the revised standardised approach.

  • Initiate data sourcing process for additional elements required under the standardised approach.

  • If a new system is required for the calculation of the standardised approach, gather requirements for the new strategic system and initiate your organisation’s RFP process.

  • Implement a simplified standardised approach calculation using proven technology to facilitate the transition and test the strategic solution

4. Key Challenges



  • Recognising the potential increase in capital requirements as a result of the capital floor

  • Calculating credit RWA using multiple methodologies (e.g. IRB approach and standardised approach)

  • Understanding and mapping regulatory reporting changes

  • Identifying and sourcing new data items required for the standardised approach

  • Implementing the mandatory rule-based standardised calculations, as well as internal variations

  • Designing automated reporting to compare RWA under the IRB and the standardised approach on an asset class level

5. How can Monocle assist



  • Monocle assists institutions with the strategic design of regulatory risk reporting systems, utilising a strong understanding of calculation engine changes, additional data derivations and updated reporting requirements.

  • Monocle has substantial experience in designing, building and implementing standardised credit risk engines under the Basel II guidelines and a sound understanding of the requirements of the Basel IV standardised approach.

  • Monocle has established an extensive data dictionary of attributes required for the standardised approach. This will fast-track the performance of a gap analysis, enabling organisations to source new data early on.

  • Monocle is, at present, involved in multiple ongoing Basel IV implementations and can leverage lessons learnt in these projects.

  • Monocle consultants are equipped with a deep understanding of the subject matter, extensive experience in the finance domain and rigorous technical training. Our team takes a hands-on approach to the management of the organisation’s data and offers pragmatic assistance in solving any challenges.
