ICI's latest weekly "Money Market Mutual Fund Assets" report shows assets dipping below the $2.8 trillion level. The release says, "Total money market mutual fund assets decreased by $9.28 billion to $2.788 trillion for the week ended Tuesday, December 21, the Investment Company Institute reported today. Taxable government funds decreased by $5.89 billion, taxable non-government funds decreased by $4.13 billion, and tax-exempt funds increased by $740 million." According to Crane Data's calculations based on ICI's weekly numbers, money fund assets have declined by $505 billion, or 15.3% YTD in 2010.

Money funds assets have dipped just below the $2.8 trillion level on several occassions in the second half of 2010, but they've managed to hold around this level since June of this year.
