Dimensional Global Sustainability Fixed Income ETF (DFSB) is an actively managed exchange-traded fund that provides exposure to a diversified portfolio of investment-grade fixed income securities from developed markets worldwide, with a focus on sustainability factors. The ETF invests primarily in USD-hedged government bonds, corporate bonds rated BBB or above by S&P/Fitch or Baa3 or above by Moody's, mortgage-backed securities, and agency debt; its portfolio includes non-U.S. bonds (58.50%), U.S. bonds (38.65%), and cash equivalents (2.79%), with top holdings such as United Kingdom of Great Britain and Northern Ireland 1.125%, Federal National Mortgage Association securities, and Government National Mortgage Association bonds. Managed by Dimensional Fund Advisors LP (co-managed by Dimensional Fund Advisors Ltd. and DFA Australia Limited), the fund targets mid-credit quality and moderate interest-rate sensitivity, benchmarking against the Bloomberg Global Aggregate Bond Index (USD-hedged), with an expense ratio of 0.24% and approximately $500-600 million in assets under management.
Launched on November 15, 2022, as part of Dimensional ETF Trust and domiciled in the United States, DFSB operates globally with emphasis on developed markets and serves institutional and retail investors seeking sustainable fixed income exposure. Dimensional Fund Advisors, the ETF's sponsor, founded in 1981 and headquartered in Austin, Texas, manages the fund through a team including David Plecha, Joseph Kolerich, and Lacey Huebel, leveraging systematic strategies informed by academic research across its 15 offices in the U.S., Canada, U.K., Germany, Netherlands, Australia, Singapore, and Japan.
In recent developments, Dimensional Fund Advisors expanded its ETF suite with seven new funds in 2023, including fixed income offerings, growing its ETF assets to over $200 billion across more than 40 funds; in 2025, the firm announced plans to launch UCITS ETFs in Europe by year-end, supported by a partnership with State Street for the initial Global Core Equity UCITS ETF and Targeted Value UCITS ETF listings in Ireland. These expansions reflect ongoing strategic growth in ETFs and global fixed income capabilities, complementing DFSB's sustainability-focused mandate without direct changes to the fund itself.
