CP9/26 – Basel 3.1: Adjustments to the internal model approach (IMA) for market risk

What Changed

• - The PRA is consulting on a targeted set of adjustments to the market risk IMA rules and related policy materials that were finalized in PS1/26.
• The proposals include replacing the existing partial caps on IMA capital with a permission-based cap on IMA capital at the full ASA level.
• The PRA proposes to adjust the treatment of collective investment undertakings (CIUs) by introducing a 90% de minimis look-through threshold for IMA inclusion.
• The PRA proposes to extend the ASA treatment of index-tracking funds to IMA.
• The PRA proposes to update reporting and disclosure obligations so they align with the revised IMA framework.
• The PRA proposes additional minor adjustments and clarifications to improve risk sensitivity and remove ambiguity in the IMA framework.

Suggested Considerations

• Review the proposed IMA amendments in CP9/26 against current Basel 3.1 implementation plans and identify where trading desk, model, and capital calculations would change.
• Assess whether any current or planned IMA portfolios would be affected by the proposed permission-based cap at the full ASA level.
• Recalculate the implications of the proposed 90% CIU de minimis look-through threshold for portfolio classification and capital treatment.
• Check whether index-tracking fund positions should be re-mapped under the proposed extension of ASA treatment to IMA.
• Update reporting and disclosure implementation workstreams to reflect the PRA’s proposed alignment changes.
• Validate whether any reduced-risk-factor modelling strategy can satisfy the proposed 75% variability coverage expectation and whether PRA notification would be required.
