Fund profile
As filed in the prospectus · 2026 Q2
The iShares 1-3 Year Treasury Bond ETF (the Fund ) seeks to track the investment results of an index composed of U.S. Treasury bonds with remaining maturities between one and three years.
The fund tracks the ICE U.S. Treasury 1-3 Year Bond Index using representative sampling, holding a sample of Treasury securities with one to three years remaining maturity that collectively mirrors the index's characteristics rather than holding all constituents. Because the fund samples the index rather than replicating it fully, its returns may diverge from the index. The fund may lend securities representing up to one-third of its assets.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026
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 | 6.0% |
| 1-3y | 94.0% |
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
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 | 100% |
| Credit spreads | 0% |
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 | +0.00 yr |
Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
| 3 mo | 0.01 yr | 0% |
| 1 yr | 1.29 yr | 69% |
| 5 yr | 0.58 yr | 31% |
| 3 mo | 0.00 yr | 100% |
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.
