According to Crane Data's separate Money Fund Intelligence Daily series, money fund assets have increased by $55.5 billion in August (through 8/6/25) to $7.526 trillion. Assets broke above $7.5 trillion on August 4, hit a new record high of $7.532 trillion on August 5, but have since inched lower. Assets increased by $63.7 billion in July, $6.7 billion in June and jumped by $100.9 billion in May. They fell by $24.4 billion in April, but rose $2.8 trillion in March, $94.2 billion in February and $52.8 billion in January. They jumped $110.9 billion in December, $200.5 trillion in November, $97.5 billion in October, $149.8 billion in September and $109.7 billion last August. Note that ICI's asset totals don't include a number of funds tracked by the SEC and Crane Data, so they're almost $400 billion lower than Crane's asset series.
