On 27 November 2023, the Basel Committee on Banking Supervision (Basel Committee) published a supervisory newsletter on the adoption of the Principles for Operational Resilience (POR) and the revised Principles for the Sound Management of Operational Risk (PSMOR). The newsletter reports on the Basel Committee’s evaluation of the POR and the PSMOR in early 2023 noting their effectiveness and maturity of adoption varies between banks. For example, while banks’ operational risk management governance (PSMOR) is well established, board members’ roles and responsibilities and capabilities for operational resilience were still under development (POR). Therefore, despite progress in adopting the POR and the PSMOR further effort is needed by banks to enhance practices and in some jurisdictions full adoption of the POR and the PSMOR may take until at least 2025.
