Schwab Treasury Inflation Protected Securities Index Fund
U.S. bond index fund · tracks Bloomberg US Treasury Inflation-Linked Bond Index (Series-L)
As of its 2026 Q2 report, Schwab Treasury Inflation Protected Securities Index Fund held 49 positions with $3.13B in net assets. Its ten largest holdings made up 36.0% of the fund. The SWRSX share class costs 0.05% a year. Over the 12 months to May 2026, SWRSX returned 4.8%, with dividends reinvested. In 2026 Q2 it added 2 new positions and exited 1.
The funds goal is to track as closely as possible, before fees and expenses, the total return of an index composed of inflation-protected U.S. Treasury securities.
The fund tracks the Bloomberg US Treasury Inflation-Linked Bond Index (Series-L), which comprises publicly issued Treasury Inflation-Protected Securities with at least one year to maturity, investment-grade ratings, and at least $500 million in outstanding face value. The fund generally holds the same securities as the index with the same weightings, though it may deviate to avoid odd-lot purchases, for tax efficiency, or to address liquidity constraints. The investment adviser may use sampling techniques, investing in a subset of index securities expected to perform similarly to the index as a whole based on interest rate, yield curve, and maturity risk factors. Up to 10% of assets may be invested outside the index in high-quality liquid government securities, anticipated index additions, or investment companies to minimize tracking differences.

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.
| 1-3y | 27.2% |
| 3-5y | 22.8% |
| 5-10y | 35.4% |
| 10y+ | 14.5% |
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 | 0.00 yr | 0% |
| 1 yr | 0.61 yr | 10% |
| 5 yr | 2.03 yr | 32% |
| 10 yr | 2.38 yr | 37% |
| 30 yr | 1.41 yr | 22% |
| 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.
