The Board of Governors of the Federal Reserve discontinued the Money Market Mutual Fund Assets Report (FR 2051a; OMB No. 7100-0012) in April 2010. However, the Investment Company Institute (ICI) will continue to collect the data for its own purposes and share it with the Federal Reserve.
The ICI conducts a weekly survey and provides the Federal Reserve with the net value of total shares outstanding (total assets less expenses and management fees) of money market mutual funds (MMMFs).
The Federal Reserve uses the MMMF data to construct the M2 monetary aggregate and to analyze current money market conditions. The monetary aggregates are published in the weekly H.6 Money Stock and Debt Measures statistical release (http://www.federalreserve.gov/econresdata/releases/statisticsdata.htm) and in the Federal Reserve Bulletin. Retail and institutional MMMF data, along with IRA/Keogh balances at MMMFs, also are published as separate items on the H.6 release.
