The muni market seems healthy. Other than the cases where budgets are exploding, the market as a whole has characteristically low yields and looks stable, especially because of excess investor demand from the recent tax changes. However, there are structural concerns about the market. Nuveen and Vanguard have come to dominate the market through their funds, sucking up to two-thirds of all the Dollars flowing into the market in the last decade. This is because investors have been increasingly buying muni funds, not individual securities. However, according to UBS, this is a big risk. “When everyone runs for the exit at the same time…no one wants to be the buyer of last resort … The concentration in large municipal asset managers will have ramifications during volatile times in that it will make the swings greater one way or another”.
FINSUM: Everyone has been warning about big runs on fixed income funds in a market downturn, but evidence of such has yet to materialize.
