This document discusses the causes of the 2008 world financial crisis from a risk management perspective. It describes the key events of the crisis and its global impact. Some of the main factors that contributed to the crisis included deregulation of the financial sector, speculation in the housing market, extensive sub-prime lending and securitization of risky mortgage-backed assets. A lack of oversight of the shadow banking system and conflicts of interest in the credit ratings agencies also exacerbated risk-taking behavior in the financial system.
