Its top positions are Treasury Notes with varying maturities, and the fund’s thirteen-year track record means it has weathered several interest rate cycles.SCHO, by contrast, is more concentrated, with just ninety-seven holdings and a focus on U.S. Treasury securities. Its largest positions are Treasury Notes and a small money market holding. While both funds avoid major quirks or leverage, SCHO’s portfolio is simpler and more directly tied to government debt.For more guidance on ETF investing, check out the full guide at this link.What this means for investorsShort-term bond allocations are usually meant to protect capital, but the kind of bonds you pick affects how much credit risk you take on. This consideration is central to the comparison between the Schwab Short-Term U.S. Treasury ETF and the iShares Core 1-5 Year USD Bond ETF.SCHO invests almost exclusively in U.S. Treasury securities with maturities of one to three years. These bonds carry minimal credit risk due to government backing, and returns depend mainly on short-term Treasury yields. In contrast, ISTB combines Treasuries with investment-grade corporate bonds and securitized assets, such as mortgage and asset-backed securities, with maturities between one and five years. This broader mix increases exposure to corporate credit conditions, resulting in a modestly higher yield.For investors, the distinction comes down to what role short-duration bonds should play in your portfolio. SCHO provides straightforward exposure to Treasury debt and tends to closely track movements in government yields. ISTB offers a broader slice of the short-maturity bond market, where additional income comes from exposure to corporate and securitized debt rather than U.S. government bonds alone.Read NextMar 3, 2026 •By Sara AppinoVCSH or ISTB?
