Meanwhile, the 1,119 taxable reporting funds saw a generous $3.58 billion increase in cash, which drove assets up to $2.319 trillion in the week ended Oct. 18.

The inflows were a marked improvement from the previous week, when the funds had just $848.4 million of inflows and total net assets settled at $2.315 trillion.

The average seven-day simple yield for the taxable funds remained at 0.02% for the 12th week straight, while the average maturity increased by one day to 41.
