(17)Delays in the implementation of the new market risk framework in jurisdictions with internationally active banks mean that those Union credit institutions that have sophisticated trading activities and more complex portfolios would face an unlevel playing field, should the implementation of the Basel III standards be delayed beyond 1 January 2027 or the requirements be implemented in a more flexible manner in other jurisdictions. Monitoring of the implementation of the Basel III standards in other major jurisdictions has demonstrated that it is highly unlikely that major non-Union banks would have to implement the FRTB rules in their home jurisdictions from 1 January 2027. At the same time, to ensure that specific aspects of the new market risk framework, in particular in relation to the alternative internal model approach, are not excessively complex or too conservative, and hence do not lead to unjustified operationally complexity or outsized capital requirements, it is necessary to reassess (and potentially recalibrate) those specific aspects. In that context, and to limit potential competitive disadvantages that would have negative impacts on the competitiveness of the Union banking sector in that area and on the financing of the Union economy, credit institutions that are adversely impacted by the implementation of the new market risk rules, after applying the targeted amendments introduced by this Regulation, should be allowed to limit that capital impact for the three-year duration of this Regulation.
