Bloomberg writes, "Muni money funds show signs of life," which tells us, "If 2017 was the year the municipal money market funds stopped bleeding assets, 2018 is the year they've started growing again. Tax-exempt money market fund assets have increased by almost $7 billion since the beginning of the year, seven times as much as all last year, according to Investment Company Institute data.... Yields on municipal securities that reset weekly rose to 1.71% at the end of December, the highest since October 2008, after the Federal Reserve raised interest rates for the third time in 2017. Since then, yields have dropped to 0.98%." The article explains, "Tax-exempt money market funds are growing again after tepid growth in 2017 and the hemorrhaging of more than $100 billion in the first 10 months of 2016, a reaction to Securities and Exchange Commission rules aimed at reducing the risk of runs on the pools. The rules required municipal money market funds to adopt floating net-asset values and imposed liquidity fees and redemption suspensions under certain conditions." They quote "You had the double whammy of zero yields and regulatory changes," said Peter Crane, president of Westborough, Mass.-based Crane Data." Bloomberg adds, "Municipal money market fund assets have grown to $138.1 billion as of Feb. 7 from $131.2 billion on Dec. 27, ICI said."
