Big challenges still lie ahead for many debt-stricken municipalities, including Detroit, Stockton and Puerto Rico.
But overall, the municipal bond market, $3.7 trillion and counting, managed to outperform nearly all other asset classes in 2014, including U.S. equities, treasuries, investment-grade and high-yield corporate bonds.
So what lies ahead after last year's stellar performance?
According to Peter Hayes, head of the $116 billion municipal bond group at BlackRock, the outlook remains bright, provided you rein in expectations.
Hayes told CNBC's "Power Lunch" Thursday "Those outsize returns of 2014 are a thing of the past, particularly in a rising rate environment. It is simply not in the cards. We'll get just fraction of the returns we saw last year
Investors shouldn't expect smooth sailing either. "While the road ahead looks positive," said Hayes, "I anticipate quite a bit of volatility along the way. "
