Money market funds had net new cash flows of $102.78 billion in January, and all-time record, according to the Investment Company Institute of Washington, D.C. That represents 75 percent of the total net cash flow into U.S. mutual funds in January and follows flows of only $16.42 billion into money market funds in December, according to the ICI.

Eighty percent of the flows into money market funds last month were from corporations reacting to the falling interest rates of alternative investments, according to the ICI. Specifically, when interest rates of direct money market investments fall, it can be advantageous for corporations to move money into money market funds since the decline will affect the funds more slowly, according to John Collins, a spokesperson for the ICI.
