Crane Data's latest monthly Money Fund Portfolio Holdings statistics will be sent out Friday, and we'll be writing our regular monthly update on the new May 31 data for Monday's News. But we also uploaded a separate and broader Portfolio Holdings data set based on the SEC's Form N-MFP filings on Thursday. (We continue to merge the two series, and the N-MFP version is now available via our Portfolio Holdings file listings to Money Fund Wisdom subscribers.) Our new N-MFP summary, with data as of May 31, includes holdings information from 979 money funds (down 8 from last month), representing record assets of $5.859 trillion (up from $5.760 trillion). Prime MMFs now total $1.189 trillion, or 20.3% of the total. We review the new N-MFP data, and we also look at our revised MMF expense data, which shows charged expenses mostly flat but money fund revenues up again in May. (Note: Please join us for our upcoming Money Fund Symposium, which is scheduled for June 21-23, 2023 in Atlanta, Ga.)
Our latest Form N-MFP Summary for All Funds (taxable and tax-exempt) shows Repurchase Agreement (Repo) holdings in money market funds increased to $3.379 trillion (up from $3.270 trillion), or 57.7% of all assets.

In related news, money fund charged expense ratios (Exp%) were mostly flat in May. Our Crane 100 Money Fund Index and Crane Money Fund Average were 0.26% and 0.38%, respectively, as of May 31, 2023. Crane Data revises its monthly expense data and gross yield information after the SEC updates its latest Form N-MFP data the morning of the 6th business day of the new month. (They posted this info Thursday morning, so we revised our monthly MFI XLS spreadsheet and historical craneindexes.xlsx averages file to reflect the latest expenses, gross yields, portfolio composition and maturity breakout, yesterday.) Visit our "Content" page for the latest files.
Our Crane 100 Money Fund Index, a simple average of the 100 largest taxable money funds, shows an average charged expense ratio of 0.26%, down 1 bp from last month's level (but 18 bps higher than 12/31/21's 0.08%). The average is close to back at the level (0.27%) it was on Dec. 31, 2019, so we estimate that funds are charging normal expenses (though they are waiving a minimal amount of fees for competitive purposes). The Crane Money Fund Average, a simple average of all taxable MMFs, showed a charged expense ratio of 0.38% as of May 31, 2023, unchanged from the month prior and now slightly below the 0.40% at year-end 2019.
Prime Inst MFs expense ratios (annualized) average 0.31% (unchanged from last month), Government Inst MFs expenses average 0.26% (unchanged from last month), Treasury Inst MFs expenses average 0.30% (unchanged from last month). Treasury Retail MFs expenses currently sit at 0.52%, (unchanged from last month), Government Retail MFs expenses yield 0.55% (unchanged from last month). Prime Retail MF expenses averaged 0.48% (unchanged from last month). Tax-exempt expenses were also unchanged at 0.40% on average.
Gross 7-day yields rose again during the month ended May 31, 2023. The Crane Money Fund Average, which includes all taxable funds tracked by Crane Data (currently 753), shows a 7-day gross yield of 5.06%, up 24 bps from the prior month. The Crane Money Fund Average was 1.72% at the end of 2019, 0.15% at the end of 2020 and 0.09% at the end of 2021. Our Crane 100's 7-day gross yield was up 24 bps, ending the month at 4.98%.
According to our revised MFI XLS and Crane Index numbers, we now estimate that annualized revenue for all money funds is a record $15.403 billion (as of 5/31/23). Our estimated annualized revenue totals increased from $15.143B last month and are up from $14.927B two months ago. Revenue levels are more than five times larger than May's 2021's record-low $2.927B level. Charged expenses and gross yields are driven by a number of variables, but revenues should continue their climb higher as money funds continue to rake in assets from uninsured bank deposits.
