iShares Core Global Aggregate Bond UCITS ETF is an exchange-traded fund that seeks to track the Bloomberg Global Aggregate Bond index, providing diversified exposure to global investment grade bonds. It invests directly in a broad portfolio of government, government-related, corporate, and securitized bonds issued in developed and emerging markets worldwide, covering all maturities. The ETF employs a physical sampling technique to replicate the index's performance, accumulating interest income from coupons and reinvesting it to support long-term growth. Key holdings include securities from major issuers such as United States Treasury, Japan Government, China Peoples Republic of Government, and various mortgage-backed securities from entities like Federal Home Loan Mortgage Corporation and Federal National Mortgage Association. Domiciled in Ireland and launched in 2024, this UCITS-compliant fund offers investors unhedged currency exposure in USD, playing a core role in fixed income portfolios by delivering comprehensive access to the international bond market's investment grade segment.
