HYMBSPDR Nuveen Bloomberg High Yield Municipal Bond ETF

Issuer: State Street Global Advisors / NuveenExpense Ratio: 0.35%Benchmark: Bloomberg Municipal High Yield IndexInception: 2009

HYMB provides exposure to high-yield (below-investment-grade) municipal bonds, offering federally tax-exempt income at higher yields than investment-grade munis. The high yield is achieved by holding bonds from municipalities with weaker credit profiles, higher debt loads, or bonds in non-traditional muni sectors. HYMB can be attractive to high-income investors seeking tax-exempt income but requires acceptance of meaningful credit risk beyond standard investment-grade munis.

Strategy

  • Use a small allocation alongside investment-grade munis (MUB) for a yield enhancement
  • Calculate tax-equivalent yield carefully — benefit is most pronounced in 32%+ brackets
  • Maintain limited position size given the credit risk relative to investment-grade munis
  • Monitor closely for credit deterioration among high-yield muni issuers

Best For

  • High-income investors in 32%+ federal tax brackets who want enhanced tax-exempt yield
  • Sophisticated muni bond investors who understand high-yield municipal credit risk
  • Income-focused investors willing to accept below-investment-grade muni credit risk
  • Taxable account investors supplementing investment-grade muni core with higher yield

Key Risks

  • Below-investment-grade credit risk — high-yield munis have elevated default probabilities
  • Lower liquidity than investment-grade muni ETFs, especially during market stress
  • Higher expense ratio (0.35%) than investment-grade muni alternatives
  • AMT risk on some holdings despite the overall fund's federal tax-exempt status

Frequently Asked Questions

What makes HYMB different from MUB?

MUB holds investment-grade municipal bonds (BBB or higher) while HYMB holds high-yield (below-investment-grade) munis. HYMB offers higher yields but with significantly more credit risk and lower liquidity. This is educational content, not financial advice.

Is HYMB income truly tax-exempt?

Most of HYMB's income is exempt from federal income tax, but some holdings may be subject to AMT or state income taxes. The tax treatment of specific bonds varies. Consult a tax advisor. This is educational content, not financial advice.

How does HYMB compare to HYD?

Both hold high-yield municipal bonds at similar expense ratios (~0.35%). They track different high-yield muni indexes and may have slight differences in composition and performance. Both carry meaningful credit risk. This is educational content, not financial advice.

Should HYMB be a core bond holding?

Generally no. HYMB's high-yield credit risk and lower liquidity make it better suited as a small satellite allocation alongside a core investment-grade muni fund. This is educational content, not financial advice.

What are tobacco settlement bonds?

Tobacco settlement bonds are a common component of high-yield muni portfolios. They are bonds backed by payments from tobacco companies to states as part of the 1998 Master Settlement Agreement. Their credit quality depends on tobacco consumption trends. This is educational content, not financial advice.
