"The 2007—8 banking crisis in the advanced economies has exposed deficiencies in risk management and prudential regulation approaches that rely too heavily on mechanical, albeit sophisticated, risk management models.

Policymakers and bankers need to recognise the limitations of rules-based regulation and restore a more discretionary and holistic approach to risk management."
