Banking regulation is inappropriate for MMFS and would end MMFs as we know them at great cost to the millions of investors who value them for their efficiency and safety, and to the financial system as a whole. 

Already subject to a comprehensive regulatory regime, amendments in 2010 to the rules governing money market funds tightened regulation even further to make money funds more resilient to certain short-term market risks, and to provide greater protections for investors in a money market fund threatening to "break the buck."  More recently, however, Federal Reserve officials and some members of the Financial Stability Oversight Council have said money market funds are subject to runs, a source of systemic risk, and part of a shadow banking system that sorely needs even more regulation.  In response, Melanie L. Fein, former senior legal counsel to the Board of Governors of the Federal Reserve System has published a paper describing why further changes to the money market regulatory regime are unwarranted overkill.
