According to Crane Data's separate Money Fund Intelligence Daily series, money fund assets have risen by $5.4 billion in June (through 6/5) to $6.479 trillion. (They hit a record $6.538 trillion on 4/2.) Assets rose by $91.4 billion in May, 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.
