"Rating Agencies' Game Worse Than Madoff's Scheme"

Another vote for my preferred major cause of our financial problems: the failure of the ratings agencies which, in turn, was at least partly government-induced.

By law, certain investors must rely on the ratings of a handful of Securities and Exchange Commission designated “Nationally Recognized Statistical Rating Organizations” (NRSROs). For example, most state insurance regulators require that only assets rated in the top four ratings categories by NRSROs are eligible investments. Similarly, money market funds can only invest in securities with the highest NRSRO ratings. In fact, innumerable institutions – public and private, and domestic and international – mandate asset quality levels predicated on the major rating agencies’ due diligence.
