Investors comparing two popular intermediate-duration bond exchange-traded funds—Vanguard Intermediate-Term Corporate Bond ETF and iShares 3-7 Year Treasury Bond ETF—are weighing income potential against credit risk and long-run volatility. The Vanguard fund, which holds investment-grade corporate debt, carries a meaningfully higher trailing distribution yield than the iShares Treasury-focused ETF, while the iShares fund has historically shown a smaller maximum drawdown and lower price sensitivity.
Key takeaways
- Expense and income: Vanguard Intermediate-Term Corporate Bond ETF charges 0.03% versus 0.15% for iShares 3-7 Year Treasury Bond ETF, and it also shows a higher trailing-12-month dividend yield of 4.80% versus 3.60% (data as of June 17, 2026).
- Different credit exposure: iShares focuses on U.S. Treasuries, while Vanguard holds investment-grade corporate bonds, introducing more credit risk even though its holdings are rated investment grade.
- Risk profile: Over five years, the reported maximum drawdown is (20.50%) for Vanguard versus (13.90%) for iShares, reflecting the corporate credit component.
- Investor implication: Income-seeking investors may prefer Vanguard’s higher yield and lower fees, while more conservative investors may favor iShares for stability and Treasuries’ capital-preservation characteristics.
What’s driving the difference
At the portfolio level, the ETFs target different segments of the fixed-income market. The iShares fund is designed to track an index of U.S. Treasury securities with remaining maturities between three and seven years. That structure typically supports steadier pricing because it excludes corporate default risk and relies on government backing.
The Vanguard fund aims to provide higher income by investing in investment-grade corporate debt. It targets securities with dollar-weighted average maturities of five to 10 years, which generally means it can be more sensitive to interest-rate moves than a shorter-dated Treasury strategy. The corporate credit exposure is the key trade-off: returns depend not only on interest rates but also on the financial health of issuers.
Cost, yield, and volatility trade-offs
According to the article data, the Vanguard ETF is the lower-cost option with an expense ratio of 0.03% compared with 0.15% for iShares. Over time, the fee gap matters for compounding—particularly in a segment where returns can be sensitive to interest-rate cycles.
On income, the Vanguard fund’s trailing-12-month dividend yield is listed at 4.80%, about 1.15 percentage points higher than the iShares yield of 3.60% (both as of June 17, 2026). For investors allocating to bonds for cash flow, the higher distribution rate is a direct differentiator.
Risk measures in the provided comparison also favor the Treasury-focused ETF. The article cites a beta of 0.33 for Vanguard and 0.14 for iShares, indicating that the Vanguard fund has historically exhibited greater price volatility relative to the S&P 500 than the iShares fund. The five-year maximum drawdown figures—(20.50%) for Vanguard and (13.90%) for iShares—are consistent with that pattern and reflect the added uncertainty from corporate credit.
How the bond holdings shape outcomes
The iShares 3-7 Year Treasury Bond ETF has 82 holdings in the article’s description, with largest positions listed as Treasury Notes maturing in 2030 and 2031. Because Treasuries remove company-specific credit risk, investors generally focus on the interest-rate environment when evaluating this ETF.
The Vanguard Intermediate-Term Corporate Bond ETF holds 343 holdings, with the article noting that the portfolio is diversified and that no single position exceeds 0.31%. However, credit quality distribution still matters: the article states that 47% of the fund is in BBB-rated bonds. That rating bucket can be more sensitive to economic deterioration than higher-quality credits, which helps explain why the fund’s drawdown and volatility measures are weaker than those of the Treasury ETF.
The article also reports the funds’ reported trailing distributions: the iShares ETF paid $4.26 per share over the trailing 12 months, while Vanguard’s trailing-12-month dividend is listed as $3.95 per share. It additionally notes that the iShares ETF was launched in 2007 and Vanguard’s in 2009.
Market reaction and what investors may watch next
While the provided article centers on structural differences rather than a near-term catalyst, the implications for investor positioning are clear: changes in Treasury yields tend to affect both ETFs, but corporate spreads—how much investors demand to be paid for credit risk—can widen or tighten based on economic conditions and investor risk appetite. In periods where credit spreads move against corporate issuers, the Vanguard fund’s higher income can come with increased total-return variability.
For the next decision point, investors should monitor the broader rate outlook and the credit cycle. Upcoming Federal Reserve communication and inflation data can influence Treasury yields, while economic indicators and default-risk perceptions can shape corporate spread behavior. Investors also may want to reassess how much of their fixed-income allocation is intended to serve as a stability anchor versus a higher-yield sleeve that tolerates drawdowns.
