How To Pick The Right Muni Bond ETF

April 18, 2016

With volatility in global markets and the challenges of investing in municipal bonds continuing to grow (reduced liquidity, low rates, under-funded pensions, increased political risk, etc.), the interest in professionally managed muni ETFs has gone up.

When selecting municipal bond ETFs, all of the other standard guidelines of a fixed-income portfolio apply, including:

  • Don’t select based only on the highest yield available. Be sure you understand the other risks involved in generating that yield.
  • Don’t reach for yield—when considering high-yield investments, it should be for a portion of the total fixed-income allocation. (ETFs provide an easy way to achieve very broad credit diversification.)
  • Don’t try to time interest rates. (Click here to read my article explaining the difficulty of trying to time rates.) Let your asset allocations be determined by your goals and investment policy. The interest-rate environment can influence how much interest-rate risk you take on, but should not lead you to eliminate or reduce your allocation to bonds. Keep in mind that overweighting your cash allocation at the expense of your fixed-income allocation may not sufficiently diversify your equity exposure and can increase your reinvestment risk.

By understanding how to evaluate duration, dividends, yield to maturity, taxable equivalent yield and credit risk when selecting a muni ETF, investors can be more confident in using ETFs as a liquid and well-diversified way to replace or add to their exposure to the municipal bond market.

  • In the chart, the Generic Muni Triple-A yield curve is based on The Consensus Municipal Bond Triple-A G.O. Par Bond Scale, published by Municipal Market Analytics LLC.
  • The chart (and the table above) exclude BAB and BABS, as those ETFs invest in taxable Build America Bonds. (Build America Bonds share similar creditworthiness as other municipal bonds, but are federally taxable. While they can be an attractive alternative to other taxable bond ETFs, they are outside the scope of this article, which is looking only at federally tax-exempt municipal bond ETFs.) The chart also excludes XMPT, because it invests in leveraged closed-end muni bond funds, and while it has a long duration, a specific duration value was not available.
  • ETF investors not already familiar and comfortable with the municipal bond market may wish to start by visiting the Municipal Securities Rulemaking Board’s Education Center.
  • Experienced municipal bond investors who want to learn more about the ETF wrapper should start with the Bond Channel.
  • Equity investors unfamiliar with bond investing may wish to read my article Bonds Are Not Stocks, which explains what equity investors should know about bond investing.
