Market regulators on Wednesday proposed to reduce money market mutual funds' reliance on credit-ratings.

The proposal by the Securities and Exchange Commission would remove a regulatory requirement for money market funds to invest in highly-rated securities.

As required under current regulations, however, the funds' board of directors would still need to demonstrate that the underlying securities are of a high quality and pose little credit risk.
