Which looks like the better buy
Vanguard Total Bond Market ETF and iShares 3-7 Year Treasury Bond ETF are both designed to provide diversified fixed-income exposure and regular monthly distributions. Each holds investment-grade bonds, carries interest rate risk, and may lose value when market yields rise. Which one is a better buy depends, in part, on what you're looking for.
BND may be a better buy if
- You're looking for a lower expense ratio: At 0.03%, BND's expense ratio is one-fifth that of IEI's.
- You need broader diversification: BND provides broad exposure to U.S. investment-grade bonds, including Treasuries, mortgage-backed securities, agencies, and corporate bonds. IEI is limited to intermediate-term Treasuries.
- Income potential is important to you: Corporate and mortgage-backed holdings may offer higher long-term yield than Treasury-only holdings.
IEI may be a better buy if
- You're concerned about credit risk: IEI holds only U.S. Treasuries, eliminating exposure to corporate defaults -- unlike BND's inclusion of corporate bonds.
- You want a fund that offers simplicity and transparency: A pure Treasury portfolio is easier to evaluate than BND's mix of sectors.
- You want an ETF that holds steady during market volatility: While there's no guarantee, Treasuries often outperform corporate holdings during market turmoil.
If you're looking for a low expense ratio, broad diversification, and steady income potential, the Vanguard Total Bond Market ETF may be right for you. However, if your portfolio can use a simple, transparent ETF likely to hold steady during market downturns, IEI is worth a closer look.
