Fund profile

As filed in the prospectus · 2026 Q2

Vanguard 0-3 Month Treasury Bill ETF (the Fund) seeks to track the performance of a market-weighted Treasury Index with an ultra-short-term dollar-weighted average maturity.

Strategy · summarised

The fund tracks the Bloomberg U.S. Treasury Bills 0-3 Months Index using a sampling approach, holding a range of Treasury securities with maturities of three months or less that approximate the index's key characteristics. Because the fund samples rather than holds all index constituents, its returns may diverge from the index.

May 2026 and Jun 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.

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.

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.

Where the risk sits on the curve

Share of duration at each point, shortest first. This filer signs its rate and credit disclosures differently; the direction shown follows its interest-rate filing, and a negative reading is the least-supported figure here.
