Schwab US Aggregate Bond ETF (SCHZ) seeks to track the Bloomberg US Aggregate Bond Index, which measures the performance of the entire U.S. investment-grade bond market including government, corporate, mortgage-backed, and asset-backed securities with maturities over one year.
How It Works
SCHZ uses a passively managed, market-value-weighted approach that mirrors its benchmark index composition. The fund holds bonds in proportion to their outstanding market value, maintaining exposure across government treasuries, corporate bonds, and securitized debt. Rebalancing occurs monthly to reflect index changes and new bond issuances. With thousands of individual bond holdings, the ETF provides broad diversification across issuers, sectors, and maturity dates while maintaining an intermediate duration profile of approximately 6-7 years.
Key Features
- Zero expense ratio makes it one of the lowest-cost bond ETFs available, keeping more yield for investors
- Comprehensive U.S. bond market exposure including treasuries, corporates, and mortgage-backed securities in single fund
- Intermediate duration profile provides balanced sensitivity to interest rate changes compared to short or long-term alternatives
Risks
- This ETF loses value when interest rates rise, with each 1% rate increase potentially causing 6-7% price decline due to duration risk
- Credit risk exists from corporate bond holdings, which could default during economic downturns though investment-grade focus limits exposure
- Inflation erodes purchasing power of fixed bond payments, making real returns negative during high inflation periods like 2021-2022
Who Should Own This
Best suited as a core fixed-income holding (20-40% of total portfolio) for conservative investors with 3+ year time horizons seeking steady income and portfolio diversification. Low-to-medium risk tolerance required for interest rate volatility. Ideal for retirees needing current income or younger investors balancing equity risk in long-term portfolios.
