The Wall Street Journal's weekly asset and yield update says, "Investors to money-market funds contributed $54 billion in the week ended Tuesday, bringing total net assets to $3.460 trillion, according to the Money Fund Report, published by iMoneyNet Inc." See also Reuters' story.
Crane Data's separate (and less comprehensive) daily series shows assets increasing by $69 billion in the week, with yields declining by 37 bps for our Crane 100 and declining by 46 bps for our broader Crane Money Fund Average. We expect this afternoon's ICI numbers to verify that we're seeing one of the largest weekly increases ever for money funds.
