Fund profile
As filed in the prospectus · 2026 Q2
Vanguard Short-Term Treasury Index Fund (the Fund) seeks to track the performance of a market-weighted Treasury index with a short-term dollar-weighted average maturity.
The fund tracks the Bloomberg U.S. Treasury 1-3 Year Index using a sampling approach, holding a range of Treasury securities maturing between 1 and 3 years that approximate the full index in key risk factors. Because the fund samples rather than holds all index constituents, its returns may diverge from the index.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026
| Share class | 1-year | 3-year | 5-year | Vol | Worst fall |
|---|---|---|---|---|---|
| +3.08% | +12.37% | +9.27% | 1.26% | -0.86% | |
| +3.12% | +12.43% | +9.39% | 1.30% | -0.86% | |
| +3.12% | +12.45% | +9.46% | 1.27% | -0.88% |
These classes hold the same portfolio, so the 0.19pp spread over 5 years is the cost difference between them — roughly 0.04pp a year — not a difference in what they own.
May 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-05-31
Share of the fund's debt by how its coupon behaves — the fact that decides whether a rate move reaches this portfolio at all.
| Fixed rate | 100.0% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 5.1% |
| 1-3y | 94.9% |
Based on what filers reported; a filer that never reported a flag also reads as none.
Risk profile
Interest-rate and credit-spread sensitivity, both in years · as of 2026Q2
This fund filed the credit-spread disclosure and reported no sensitivity — measured, and the answer is none.
Where the loss would come from. The two shocks are the same size, so this is the balance of the fund's two sensitivities rather than a bet on one moving more.
| Interest rates | 100% |
Filers report the impact of a 0.01% move only, so the total is our own scaling of that one number and overstates the loss on most bonds — read it as approximate, never as precise. The two sensitivities overlap rather than add up: they measure the same positions against different shocks, which is why the durations above are shown side by side and never summed.
Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
