Money-market funds are regulated by the SEC. If the agency doesn't pass additional rules, the Financial Stability Oversight Council, a panel created by 2010's Dodd-Frank Act, could subject them to direct oversight by the Fed. Charged with identifying threats to the financial stability of the U.S., the FSOC is headed by the Secretary of the Treasury and its nine other voting members include the Fed chairman and heads of the SEC and Federal Deposit Insurance Corp.
