Crane Data's latest monthly Money Fund Portfolio Holdings statistics will be sent out Wednesday, and we'll be writing our regular monthly update on the new September data for Thursday's News. But we also already uploaded a separate and broader Portfolio Holdings data set based on the SEC's Form N-MFP filings on Tuesday. (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 August 31, includes holdings information from 988 money funds (down 1 from last month), representing assets of $7.701 trillion (up from $7.530 trillion a month ago). Prime MMFs rose to $1.193 trillion (up from $1.182 trillion), or 15.5% of the total. We review the new N-MFP data and we also look at our revised MMF expense data, which shows charged expenses were mostly flat and money fund revenues rose to $20.1 billion (annualized) in August.
