Crane Data's latest monthly Money Fund Portfolio Holdings statistics will be published Tuesday, June 11, and we'll be writing our normal monthly update on the May 31 data for Friday's News. But we also generate a separate and broader Portfolio Holdings data set based on the SEC's Form N-MFP filings. (We continue to merge the two series, and the N-MFP version is now available via Holdings file listings to Money Fund Wisdom subscribers.) Our new N-MFP summary, with data as of May 31, 2019, includes holdings information from 1,178 money funds (nine fewer than last month), representing assets of $3.585 trillion (up from $3.502 trillion). We review the latest data, which shows that total money fund assets remained above $3.5 trillion and Prime MMF assets remained above $1.0 trillion in May. Our latest Form N-MFP Summary for All Funds (taxable and tax-exempt) shows Repurchase Agreement (Repo) holdings in money market funds totaling $1,178 billion (up from $1,120 billion on April 30), or 32.9% of all assets.
