The Federal Reserve released its latest quarterly "Z.1 Financial Accounts of the United States" statistical survey (a.k.a. "Flow of Funds") late last week. Among the 4 tables it includes on money market mutual funds, the First Quarter 2023 edition shows that Total MMF Assets increased by $470 billion to $5.693 trillion in Q1'23. The Household Sector, by far the largest investor segment with $3.366 trillion, saw the biggest asset increase in Q1, followed by Nonfinancial Corporate Businesses. The Fed's latest Z.1 numbers, which contain one of the few looks at money fund investor segments available, also showed noticeable increases for the Other Financial Business (formerly Funding Corps), the Rest of World and the Mutual Fund categories in Q1 2023.
Private Pension Funds, State & Local Governments, Life Insurance Companies, Exchange-traded funds and the Nonfinancial Noncorporate Business categories saw small asset increases in Q1. The State & Local Govt Retirement and Property-Casualty Insurance categories were the only ones that saw assets decrease last quarter. Over the past 12 months, the Household Sector, Nonfinancial Corporate Business, Private Pension Funds, Rest of World and State & Local Governments categories showed the biggest asset increases, while Other Financial Business, Mutual Funds and State & Local Govt Retirement saw the biggest asset decreases.
The Fed's "Table L.206," "Money Market Mutual Fund Shares," shows that total assets increased by $470 billion, or 9.0%, in the first quarter to $5.693 trillion. The largest segment, the Household sector, totals $3.366 trillion, or 59.1% of assets. The Household Sector increased by $300 billion, or 9.8%, in the quarter. Over the past 12 months through March 31, 2023, Household assets were up $600 billion, or 21.7%.

Assets here increased by $71 billion in the quarter, or 9.5%, and they've increased by $44 billion, or 5.7%, over the past year. Other Financial Business was the third-largest investor segment with $435 billion, or 7.6% of money fund shares. This category jumped $53 billion, or 13.8%, in the latest quarter. Other Financial Business, which we believe includes Securities Lending, has decreased by $79 billion, or -15.4%, over the previous 12 months.

Mutual Funds (a recent addition to the tables), was the 5th largest category with 4.3% of money fund assets ($237 billion); it was up by $11 billion (4.8%) for the quarter and down $62 billion, or -20.8% over the last 12 months.

The Federal Reserve made changes to the Z.1 tables five quarters ago. Describing a "Money market funds sector data source change," the report says, "The money market mutual funds (MMF) sector (tables F.121 and L.121) has been revised beginning 2010:Q4 to reflect a change in data source to Securities and Exchange Commission Form NMFP. The level of assets and shares outstanding of the sector have increased due to the inclusion of private placement MMFs in the source data. Changes in the level due to changes in the data source in 2010:Q4 are recorded as other volume changes in the Financial Accounts."
On "Mutual funds sector holdings of money market funds," Z.1 tells us, "The mutual funds sector (tables F.122 and L.122) has been revised beginning 2010:Q4 to reflect holdings of money market funds not previously reported on the tables. In addition, holdings of repurchase agreements, commercial paper, corporate bonds, and miscellaneous assets have been revised. Additional and revised holdings are estimated using data from Morningstar and Investment Company Institute.... The exchange-traded funds sector (tables F.124 and L.124) has been revised beginning 2010:Q4 to reflect holdings of money market funds not previously reported on the tables."
