Fund profile

As filed in the prospectus · 2025 Q4

The State Street SPDR Bloomberg 1-3 Month T-Bill ETF (the Fund) seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of an index that tracks the 1-3 month sector of the United States Treasury Bill market.

Strategy · summarised

The fund tracks the Bloomberg 1-3 Month U.S. Treasury Bill Index using a sampling strategy, holding a subset of the index's securities selected to replicate its risk and return characteristics. The fund invests at least 80% of assets in index constituents and may hold cash equivalents or money market instruments for cash management. Because the fund samples rather than holds all index securities, its performance may diverge from the index.

of net assets
Cash & short-term105.09%

These positions come to 105.09% of the fund's net assets. This counts only what the fund reported holding — the holdings disclosure covers assets, not liabilities such as borrowings — so it is not expected to reconcile to 100%.

Cumulative return· Jul 2023 – Apr 2026

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.

Credit-spread duration

If rates and spreads both rise 100bp

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 rates100%

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. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
