Fund profile
As filed in the prospectus · 2026 Q2
Vanguard Extended Duration Treasury ETF, an exchange-traded share class of Vanguard Extended Duration Treasury Index Fund (the Fund), seeks to track the performance of an index of extended-duration zero-coupon U.S. Treasury securities.
The fund tracks the Bloomberg U.S. Treasury STRIPS 2030 Year Equal Par Bond Index through sampling, holding a range of zero-coupon Treasury securities with maturities between 20 and 30 years that approximate the index's key risk factors. Because the fund samples rather than holds all index constituents, its performance may diverge from the target 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 |
|---|---|---|---|---|---|
| -2.45% | -19.61% | -41.07% | 14.04% | -27.87% | |
| -2.49% | -14.07% | -36.98% | 14.04% | -27.84% | |
| -2.44% | -19.58% | -41.05% | 14.04% | -27.83% |
These classes hold the same portfolio, so the 4.09pp spread over 5 years is the cost difference between them — roughly 0.82pp 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.
| Zero-coupon or unclassified | 100.0% |
Share of the fund's debt value in each maturity band, shortest first.
| 10y+ | 100.0% |
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.
