What's inside
BSV tracks a short-term government and investment-grade bond index, holding 3,115 bonds as of now and maintaining an average effective maturity of 2.8 years. Its top holdings are U.S. Treasury securities, such as United States Treasury Note/Bond 3.63% 12/31/2030 (1.18%), and the fund invests exclusively in cash and other fixed income. There are no notable fund quirks, and the next ex-dividend date is Feb. 2, 2026.
SMB, by contrast, focuses on short-term, tax-exempt municipal bonds, reflected in its 100% allocation to cash and related instruments. Top positions include California Community Choice Financing A (1.68%), State of California (1.10%), and Commonwealth of Massachusetts (1.02%), with a broad portfolio of 334 holdings. Unlike BSV, SMB’s yield is federally tax-free, which may be appealing for taxable accounts.

What this means for investors
In the long run, both funds are solid choices. But the Vanguard Short-Term Bond ETF (BSV) stands out for its costs, returns, and diversification. Its lower expense ratio means that investors will pay roughly half the fees over time as with the VanEck Short Muni ETF (SMB).
The lower cost of BSV is even better given that it has delivered superior total returns to investors. Over the last three years, BSV returned 14.6%, beating SMB by 4.9 percentage points.
While SMB offers tax-free income, BSV’s higher yield and return history still make it an attractive alternative. Even for an investor who pays a high tax rate on income, BSV would still look like the better choice given its large number of bond holdings and lower expense ratio.
