iShares MBS ETF

iShares MBS ETF is an exchange-traded fund that seeks to track the investment results of the Bloomberg U.S. MBS Index, composed of investment-grade mortgage-backed pass-through securities issued by U.S. government agencies. It primarily invests in fixed-rate securities backed by pools of mortgages from entities such as the Federal National Mortgage Association, Federal Home Loan Mortgage Corporation, and Government National Mortgage Association, providing exposure to a diversified portfolio of over 11,000 holdings in the mortgage-backed securities sector. The fund offers investors access to the U.S. agency MBS market, which generates income from regular principal and interest payments on underlying home loans, contributing to liquidity in the housing finance system. With a low expense ratio and monthly distributions, iShares MBS ETF serves as a key vehicle in the fixed income market for those seeking broad, investment-grade mortgage exposure with characteristics like an effective duration around 5 years and a weighted average maturity of approximately 6 years. Launched in 2007 and managed by BlackRock, it remains a prominent option for retail and institutional portfolios focused on stable income within the bond market.
