Vanguard Short-Term Treasury Fund (the Fund) seeks to provide current income while maintaining limited price volatility.
The fund actively manages a portfolio weighted toward U.S. Treasury securities with a dollar-weighted average maturity of 1 to 4 years, supplemented by agency bonds and mortgage-backed securities to enhance yield. The fund may also use derivatives and TBA transactions as part of its management approach. Because the fund's returns depend on the manager's security selection and positioning decisions within its maturity band, performance will diverge from any passive benchmark.

What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| Bonds | 83.84% |
| Securitized | 15.71% |
| Cash & short-term | 0.89% |
| Derivatives | -0.01% |
The outer band is exposure held short — written against the portfolio rather than part of it, which is why it sits outside the ring and why the two are never netted into one figure.
Derivatives are shown at market value, not notional exposure.
How it has done
VFISX share class · total returns with dividends reinvested
Volatility over the last 12 months: 1.49%. Past returns are a record, not a forecast.
Jun 2026 and Jul 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
The 2 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.20% | +3.36% | +12.38% | +7.26% | -0.87% | |
| 0.10% | +3.46% | +12.71% | +7.80% | -0.86% |
These classes hold the same portfolio, so the 0.54pp spread over 5 years is the cost difference between them — roughly 0.11pp a year — not a difference in what they own.

Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-04-30
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 | 91.4% |
| Floating rate | 5.9% |
| Zero-coupon or unclassified | 2.7% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 0.0% |
| 1-3y | 63.0% |
| 3-5y | 27.0% |
| 5-10y | 0.7% |
| 10y+ | 9.3% |
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
Most of this fund’s sensitivity is to interest rates, with credit spreads carrying a small fraction as much.
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 | 82% |
| Credit spreads | 18% |
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 the fund's spread duration carried by each credit tier.
| Investment grade | +0.51 yr |
Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
| 1 yr | 1.28 yr | 55% |
| 5 yr | 0.93 yr | 40% |
| 10 yr | 0.08 yr | 3% |
| 30 yr | 0.03 yr | 1% |
3 mo is NEGATIVE (-0.01 yr) — a deliberate hedge at that point on the curve, so it is not part of the band above.
| 3 mo | 0.01 yr | 1% |
| 1 yr | 0.15 yr | 29% |
| 5 yr | 0.25 yr | 49% |
| 10 yr | 0.09 yr | 18% |
| 30 yr | 0.01 yr | 3% |
The two bands measure the same positions against different shocks and do not add — a Treasury carries rate duration and no spread duration, a floating-rate credit the reverse. Rate tenors are also summed across every currency the fund discloses.
