IUSB

The iShares Core Universal USD Bond ETF (IUSB) invests in a broad spectrum of U.S.‑dollar‑denominated taxable bonds, including Treasury, agency, corporate, mortgage‑backed, asset‑backed and high‑yield securities, with exposure to both investment‑grade and lower‑rated issuers across the United States and other dollar‑denominated issuers abroad. Its strategy is to passively track the Bloomberg U.S. Universal Index, holding at least 80 % of the index constituents and using representative sampling to mirror the index’s sector and credit composition. This approach provides diversified fixed‑income exposure in a single fund, making it suitable for investors seeking a core bond holding for income, portfolio diversification or a foundational component of a balanced investment strategy.
