According to Crane Data's separate Money Fund Intelligence Daily series, money fund assets have rose by $50.2 billion in May (through 5/8) to $6.432 trillion. (A month prior, they were a record $6.538 trillion on 4/2.) Assets fell $15.8 billion in April and $68.8 billion in March. But they rose $72.1 billion in February, $93.9 billion in January, $32.7 billion in December and $226.4 billion in November. MMF totals fell by $31.9 billion in October. They rose $93.9 billion in September, $98.3 billion in August and $34.7 billion in July. Note that ICI's asset totals don't include a number of funds tracked by the SEC and Crane Data, so they're over $400 billion lower than Crane's asset series.
