The world’s big banks haven’t done enough to bolster operational risk management, which could leave them vulnerable to substantial losses and may generate systemic risk, warn global regulators.

In a report examining compliance with its principles for managing operational risk, the Basel Committee on Banking Supervision concludes that “insufficient progress” has been made in implementing the principles that were updated in 2011 to reflect lessons from the financial crisis. The review covered 60 systemically important banks (SIBs) in 20 jurisdictions, including Canada, and is based on a self-assessment survey. It says that progress in implementing the principles varies significantly across banks; but that, overall, more work is needed to achieve full implementation.

The report notes that some systemically important banks haven’t implemented all of the principles and don’t deploy the full range of operational risk management tools. “Therefore, these banks may not be adequately identifying and managing their operational risk exposures,” it warns. “Failure to fully implement appropriate operational risk identification and management practices may result in direct and material financial losses, or reputational and consequential losses, and could lead to a systemic impact on other banks, customers, counterparties and the financial system.”

Four principles are highlighted in the report as being the least thoroughly implemented, including: operational risk identification and assessment; change management; operational risk appetite and tolerance; and, disclosure.

The committee calls on banking regulators to work with the banks under their supervision to improve compliance. And, it makes several recommendations for the banks, including that they improve the implementation of the operational risk identification and assessment tools; enhance the implementation of change management programs and processes and ensure their effective monitoring; strengthen the implementation of the three-lines of defence (business line management, independent corporate operational risk management, and an independent review), especially by refining the assignment of roles and responsibilities; and, improve board and senior management oversight, articulation of operational risk appetite and tolerance statements, and risk disclosures.

At the same time as it published its review, the Basel Committee also released a revised standardized approach for measuring operational risk capital for consultation, which aims to streamline and enhance the framework that sets out different approaches that banks can use to calculate their operational risk capital requirement. Comments on the consultation are due by Jan. 6, 2015.
