governmental regulatory action is necessary. EU <strong>in</strong>ternal market commissioner Charlie<br />

McCreevy called <strong>the</strong> code of conduct adopted by <strong>the</strong> CRAs a “toothless wonder,” because a<br />

CRA that fails to follow <strong>the</strong> code of conduct faces no significant negative consequences. EU<br />

M<strong>in</strong>isters suggested that CRA self-regulation through codes of conduct is no substitute for EU-<br />

wide registration and a “streng<strong>the</strong>ned oversight regime” to improve disclosure, help prevent<br />

conflicts of <strong>in</strong>terest, and reduce <strong>in</strong>vestor overreliance on rat<strong>in</strong>gs.<br />

B. CRAs Were Implicated <strong>in</strong> <strong>the</strong> Recent <strong>Credit</strong> <strong>Crisis</strong> Due to <strong>the</strong> Influence of Their<br />

<strong>Rat<strong>in</strong>g</strong>s of MBSs, CDOs, and F<strong>in</strong>ancial Institutions<br />

The volume of requests for rat<strong>in</strong>g structured f<strong>in</strong>ance products such as mortgage-backed<br />

securities (MBSs) and collateralized debt obligations (CDOs) <strong>in</strong>creased drastically between 2004<br />

and 2006, as did <strong>the</strong> complexity of <strong>the</strong> rated products. In h<strong>in</strong>dsight, it appears that <strong>the</strong> structured<br />

conditions <strong>in</strong> time, but <strong>the</strong>y played a central role <strong>in</strong> creat<strong>in</strong>g those market conditions. The CRAs<br />

were criticized for worsen<strong>in</strong>g <strong>the</strong> credit crisis by overvalu<strong>in</strong>g complex mortgage-backed<br />

<strong>in</strong>struments, by underestimat<strong>in</strong>g <strong>the</strong> complexity of those <strong>in</strong>struments, and by be<strong>in</strong>g slow to<br />

downgrade <strong>the</strong>m when <strong>the</strong>ir creditworth<strong>in</strong>ess worsened. In addition to <strong>the</strong> CRAs’ faulty<br />

understand<strong>in</strong>g of <strong>the</strong> mortgage-backed <strong>in</strong>struments and <strong>the</strong>ir overoptimistic view of <strong>the</strong> hous<strong>in</strong>g<br />

market, <strong>the</strong> CRA weaknesses expla<strong>in</strong>ed <strong>in</strong> Section III—conflicts of <strong>in</strong>terest, lack of transparency,<br />

and lack of competition among rat<strong>in</strong>g agencies—contributed to <strong>the</strong> overvaluation of many<br />

mortgage-backed <strong>in</strong>struments prior to <strong>the</strong> credit crisis.<br />

In a U.S. House Committee on Oversight and Government Reform <strong>in</strong>vestigation,<br />
