Bondbloxx Bloomberg Seven Year Target Duration US Treasury ETF (XSVN) is an exchange-traded fund that seeks to track the investment results of an index composed of U.S. Treasury securities with an average duration of approximately seven years; it invests at least 80% of its assets in such securities, including U.S. Treasury notes with maturities typically between five and nine years, such as top holdings like US Treas NTS 4.625% due 02/15/35, US Treas NTS 4.25% due 08/15/35, and US Treas NTS 4.25% due 11/15/34. The ETF, part of the BondBloxx suite of fixed income products managed by BondBloxx Investment Management Corporation, a firm focused exclusively on bond ETFs offering exposures to U.S. Treasuries, investment grade corporates, high yield, tax-aware strategies, and emerging markets bonds, trades on the NYSE Arca exchange with monthly distributions and an expense ratio of 0.05%. Launched on September 13, 2022, and domiciled in the United States with headquarters in Larkspur, California, XSVN targets fixed income investors seeking moderate interest-rate sensitivity and high credit quality in the long government bond segment, with total net assets exceeding $189 million as of late 2025. In October 2024, BondBloxx, the ETF's sponsor, raised $27 million in a funding round led by Macquarie Asset Management, which maintains a minority stake and will sub-advise a forthcoming private credit CLO ETF; this capital supports expansion of the firm's lineup now spanning over 24 bond funds with more than $3.4 billion in assets, alongside recent launches like tax-aware fixed income ETFs with IR+M and the first ETF providing direct exposure to private credit. The firm continues to grow amid strong inflows into fixed income ETFs, positioning XSVN within a category leader's innovative portfolio amid evolving market dynamics.
