About IUSB
iShares Core Universal USD Bond ETF is an exchange-traded fund that seeks to track the investment results of an index composed of U.S. dollar-denominated bonds issued by governments, corporations, and securitized issuers. It provides broad exposure to the U.S. bond market, including U.S. Treasury securities, mortgage-backed securities from agencies like Federal National Mortgage Association and Federal Home Loan Mortgage Corporation, investment-grade corporate bonds from major issuers such as JPMorgan Chase and Bank of America, and other fixed income instruments. The fund holds a diversified portfolio with thousands of holdings across government bonds, corporate bonds, securitized bonds, and minimal allocations to cash equivalents and municipal bonds. Designed as a core fixed income holding, it offers investors a low-cost way to access a representative cross-section of the taxable USD bond universe, emphasizing market value weighting for comprehensive coverage. Managed by BlackRock with a focus on tracking the Bloomberg U.S. Universal Index, the ETF distributes income monthly and maintains characteristics like intermediate duration and a blend of coupons and maturities typical of the broader market.
