UK regulatory update – implementation of IRRBB under CRDV

  • On 7 May 2021, the Financial Conduct Authority (FCA) published on its website – as did other UK regulators – the third six-monthly “Regulatory Grid” from the Financial Services Regulatory Initiatives Forum
  • Certain items are labelled as “key initiatives in the regulatory landscape” to get further emphasis – that includes the item summarised in this text
  • This Regulatory Grid sets out the regulatory pipeline for the next 24 months and enables firms to plan more accurately for forthcoming initiatives
  • The Regulatory Grid is published twice a year to help manage the operational impact on firms of implementing initiatives from the Forum members
  • This guidance is important for all organisations within UK financial services


  • This particular initiative – implementation of IRRBB (interest rate risk in the banking book) under the Capital Requirements Directive V (CRDV) – is being led by the Prudential Regulation Authority (PRA)
  • CRDV introduced Basel III’s enhanced Pillar 2 approach to the management and control of IRRBB
  • PRA intends to implement the Basel IRRBB standards through a combination of PRA rules and supervisory expectations
