According to Crane Data's separate Money Fund Intelligence Daily series, money fund assets have risen by $47.7 billion in July (through 7/17) to $6.537 trillion. They hit a record $6.559 trillion on 7/11 but have since eased off a bit. Assets rose by $15.7 billion in June and $91.4 billion in May, but they fell $15.8 billion in April and $68.8 billion in March. 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 and $98.3 billion in August. 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.
