The document discusses the role of credit rating agencies in the financial crisis. It provides context on how the agencies are meant to assess risk but gave high ratings to many subprime investments. This led to increased profits for the agencies but also contributed to the crisis. As the housing bubble burst, the agencies were forced to mass downgrades but only after misleading investors and failing to properly acknowledge the growing risks despite internal warnings. Their conflicting business models and cozy relationships with Wall Street compromised their ratings and exacerbated the crisis.
