Macquarie National High-Yield Municipal Bond ETF (HTAX) is an actively managed exchange-traded fund that seeks to provide a high level of current income exempt from federal income tax through investment primarily in a diversified portfolio of high-yield municipal bonds issued by U.S. state and local governments, territories, and possessions; these bonds encompass medium- and lower-grade obligations with varying maturities, emphasizing yield-focused strategies backed by bottom-up research and risk management to optimize tax-advantaged returns while mitigating volatility compared to equities or other fixed-income alternatives. The ETF targets investors seeking federal tax-exempt income from high-yield (below investment grade) municipal debt securities, which carry heightened credit, interest rate, liquidity, and prepayment risks but offer potential for competitive risk-adjusted performance; its portfolio typically holds around 100 securities, with substantially all income derived from tax-exempt sources, though some may be subject to state/local taxes or the federal alternative minimum tax. Launched on March 5, 2025, by Macquarie Asset Management (MAM), a division of Macquarie Group founded in 1969 and headquartered in Sydney, Australia, with significant U.S. fixed-income operations including an award-winning municipal bond team managing $11.8 billion in assets, HTAX operates on the NYSE Arca exchange and lists among MAM's growing suite of active ETFs distributed by Foreside Financial Services, LLC. In a major recent development, MAM expanded its active ETF platform with the March 2025 launch of HTAX, marking its second municipal bond ETF following the Macquarie Tax-Free USA Short Term ETF (STAX) and part of over a dozen active ETF introductions in the U.S. and Australia since November 2023; this initiative leverages MAM's flagship high-yield municipal bond mutual fund strategy, which has earned 5-star Morningstar ratings across multiple funds on its platform. The ETF maintains an expense ratio of 0.49%, assets under management of approximately $25.62 million, monthly dividend distributions yielding around 1.37% (trailing twelve months), and no reported acquisitions, partnerships, or reorganizations since inception as of late 2025.
