Two popular U.S. investment-grade corporate bond ETFs, VCIT and IEI, offer distinct trade-offs: VCIT targets higher yield with greater duration exposure, while IEI emphasizes stability through shorter maturities. Investors must balance income potential against interest rate sensitivity.
- VCIT offers a 5.2% yield with a 5.8-year duration, focused on investment-grade corporate bonds.
- IEI yields 4.6% with an 8.3-year duration, investing in U.S. Treasury notes with 7–10 year maturities.
- VCIT's 12-month total return was 6.9%, outperforming IEI's 5.1% over the same period.
- IEI exhibits lower volatility, with a 12-month standard deviation of 2.7% versus VCIT’s 3.9%.
- Both ETFs have over $18 billion in AUM, with VCIT exceeding $25 billion as of early 2026.
- Higher duration in IEI increases sensitivity to rate changes, though the Treasury backing reduces credit risk.
The choice between Vanguard Intermediate-Term Corporate Bond ETF (VCIT) and iShares 7-10 Year Treasury ETF (IEI) reflects a fundamental decision in fixed income investing—seeking enhanced income or prioritizing capital preservation. VCIT, with an average duration of approximately 5.8 years and a current yield of 5.2%, focuses on corporate bonds issued by investment-grade firms. In contrast, IEI, with a duration of 8.3 years and a yield of 4.6%, holds U.S. Treasury notes maturing between 7 and 10 years, offering a benchmark of safety with slightly lower returns. VCIT’s higher yield stems from its exposure to corporate credit, which compensates investors for default risk. However, this also increases sensitivity to interest rate fluctuations. With a modified duration of 5.8, a 1% rise in rates could lead to an estimated 5.8% decline in the fund’s net asset value. IEI, despite its longer duration, benefits from the perceived risk-free nature of U.S. Treasuries, making it a common haven during market volatility. Over the past 12 months, VCIT has delivered a total return of 6.9%, outperforming IEI’s 5.1% return, driven by both higher income and modest capital appreciation. However, IEI has shown lower volatility, with a 12-month standard deviation of 2.7% compared to VCIT’s 3.9%, underscoring its defensive profile. For income-focused investors, VCIT may be preferable, particularly in a rising-rate environment where credit spreads may tighten. Conversely, conservative portfolios or those seeking stability during rate uncertainty may favor IEI, despite its lower yield. Both funds remain significant tools in balanced fixed income strategies, with total assets under management exceeding $25 billion for VCIT and $18 billion for IEI as of early 2026.
