Read original Treasury real yields

1. Understand what this real yield measures

This view uses the US Treasury’s original real par constant-maturity yields derived from Treasury Inflation-Protected Securities, or TIPS. Treasury estimates its real curve from indicative secondary-market quotations and reports values at fixed maturities. A constant-maturity point need not equal the yield of one identified bond with exactly that remaining lifetime.

Datisto does not calculate this real yield by subtracting today’s CPI rate from a nominal Treasury yield. The source value is not breakeven inflation, a forecast of prices or the realised purchasing-power return of your own bond investment. Nominal and real series retain different units and source identities.

2. Compare the five reported maturities on an exact day

The real source reports 5Y, 7Y, 10Y, 20Y and 30Y. The prepared result loads automatically; select the exact source day for the cross-section. There is no reported short real maturity in this selection to substitute for a nominal one-month or one-year point. A line connecting the five visible points helps read their shape; Datisto supplies no new yield between those maturities.

The initial real capture contains 198 source days, 2 January–15 October 2026, and 990 original values. The earlier retained nominal capture ends on 14 October. Their different coverage is explicit: the latest real day cannot be paired with the previous nominal day as though both came from the same date. This view performs no such pairing or breakeven calculation.

3. Read real bond-equivalent percent and keep gaps

The unit is real par bond-equivalent percent, quoted on the source’s simple annualized convention for semiannual coupons. It is not a compounded APY, a bond price or a guaranteed annual return. Original two-place decimal strings remain available through Passport and the downloads; display rounding does not change the captured source value.

Only reported source dates are present. An absent weekend or holiday does not silently reuse the previous business day. A source missing marker stays unavailable rather than becoming zero or an interpolated value. The parser can preserve a genuinely reported negative or zero; the initial 990 actual cells are all positive, so this capture is not evidence of actual negative or zero observations.

4. Separate the source day, update and capture clocks

The printed source day identifies which day a yield belongs to. Its midnight UTC chart coordinate does not establish an intraday market measurement. Feed and entry update timestamps describe source metadata, while Datisto’s separate capture clock records when the full response was received. Neither proves an individual point’s first publication time.

Per-value publication, provider revision, period end and finality remain unknown in this source contract. A later capture may contain corrected history. Check capture and freshness separately from the selected source day; selecting a newer-looking day does not refresh the data or turn a stored estimate into a current executable quote.

5. Inspect a point and preserve the complete original

Open Value Passport from a maturity or an original historical point to inspect its exact value, real-yield unit, source field and evidence. Curve, history chart and table share one verified result. Switching the day, paging the table or hiding a legend series changes presentation, not the original query scope or the provenance of another point.
