BTOT iShares Total USD Fixed Income Market ETF

About this ETF

iShares Total USD Fixed Income Market ETF is an exchange-traded fund that provides broad, index-based exposure to the U.S. dollar-denominated taxable bond market. The fund seeks to track an index designed to capture a comprehensive range of fixed income sectors, including U.S. Treasuries, agency mortgage-backed securities, corporate bonds, securitized credit, and select international U.S. dollar issues. A substantial portion of the portfolio is allocated to obligations of the United States Treasury and U.S. government-sponsored entities, reflecting its role as a diversified core bond holding. By spanning sectors often excluded from traditional aggregate bond benchmarks, such as certain securitized and non-U.S. sovereign exposures, the ETF is structured as a single-fund representation of the modern U.S. bond universe. It serves as a foundational fixed income building block for asset allocators seeking broad market coverage, systematic index methodology, and transparent exposure to the overall U.S. dollar fixed income landscape.
