Fund profile

As filed in the prospectus · 2026 Q1

Fidelity SAI Inflation-Protected Bond Index Fund seeks to provide investment results that correspond to the total return of the inflation-protected sector of the United States Treasury market.

Strategy · summarised

The fund tracks the Bloomberg U.S. Treasury Inflation-Protected Securities Index using statistical sampling techniques across duration, maturity, and security structure to replicate returns with a smaller portfolio. Because the fund samples rather than holds all index constituents, its returns may diverge from the index. The fund may use derivatives including swaps and futures to adjust risk exposure.

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

More of this fund’s sensitivity sits in credit spreads than in interest rates — a rate rally that comes with a credit selloff works against it.

Interest-rate duration
6.47 yr
approx. move per 100bp
Credit-spread duration
6.53 yr
approx. move per 100bp
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.

≈ -13.0%
of value
Credit spreads50%
Interest rates50%

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.

Credit risk by quality

Share of the fund's spread duration carried by each credit tier.

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.

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.

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.
