iShares U.S. MBS USD Accumulating ETF

The iShares U.S. MBS USD Accumulating ETF is a passively managed exchange-traded fund designed to provide exposure to the U.S. mortgage-backed securities market. This fund primarily invests in investment-grade mortgage-backed pass-through securities issued by U.S. government agencies, such as Ginnie Mae, Fannie Mae, and Freddie Mac. Its central aim is to track the performance of a benchmark index—typically the Bloomberg US Mortgage Backed Securities Index—thus offering diversified exposure to the U.S. agency MBS sector. The fund utilizes physical replication, acquiring a representative sample of the underlying securities to closely mirror the index's risk and return profile. Interest income generated by the portfolio is accumulated rather than distributed, allowing for compounding over time. This ETF is notable for its relatively low expense ratio and significant assets under management, reflecting strong investor interest in accessing the income and diversification benefits of the U.S. mortgage market through a single, regulated vehicle. As such, the iShares U.S. MBS USD Accumulating ETF serves a crucial role for investors seeking exposure to the U.S. government-backed bond market, often as a component of broader fixed-income portfolios.
