FYI: (This is a follow-up article.)
On May 14, new rules will require brokerage firms to start disclosing some of the fees they charge individuals to buy and sell state and local government debt. Those fees, which firms build into the trades by marking the price up or down, averaged about 1.1 percent on investment-grade bonds in 2016, or $1,100 for a $100,000 bond, according to S&P Global.
Some analysts have speculated the new disclosures could accelerate a shift by individual investors toward mutual funds and other fee-based accounts. On average, long-term municipal bonds funds charged fees of 0.54 percent in 2016, according to the Investment Company Institute.
