The financial crisis of 2007-2008 was caused by a real estate market bubble fueled by subprime mortgages and a poor regulatory framework that trusted banks to self-regulate. Risk management failed in three key areas: a lack of a clear capital allocation strategy, a disaggregated view of risks across business lines, and an inappropriate risk governance structure where the role of risk managers was marginal. Moving forward, banks need to define their risk appetite framework, implement enterprise risk management to monitor all risks holistically, and strengthen their risk governance structure with independent oversight of risk at the board level.
