30Y Breakeven Inflation

What it is

30Y Breakeven Inflation — registry key breakeven_30y.

30-year breakeven inflation (nominal 30y minus 30y TIPS real). long-end supply-stress carrier, Phase 1 of improvements/long-end-stress.md; scoring deferred to a pre-registered study.

Data-pyramid tier

T1 — Signal. This metric sits at the signal layer of the platform’s six-tier data pyramid (T0 raw inputs → T5 actionable read). The tier reflects how far the value is from a raw measurement — not how strongly it is validated. Abstraction and validation are separate axes: a higher tier is not a claim of stronger evidence.

Horizon & validation

No validated skill horizon is on file for this metric — read it as context / a data carrier, not a validated edge. Stamps are added only when a gated research verdict lands.

Source

Source module: fred_macro
Data source: computed

Derived metric — produced inside the platform (app/sources/fred_macro.py or equivalent) rather than fetched as a raw upstream value. See the How it's computed section below for the formula.

How it’s computed

30-year breakeven inflation = DGS30 (nominal 30y) - DFII30 (30y TIPS real), in percentage points, both FRED same-day. NULL when either leg is missing (never 0). See app/sources/fred_macro.py (_collect_long_end / _spread).

Where it surfaces

Health-score / alignment role

Data carrier — no implication, no health-score contribution.

Persisted for downstream consumers (sparklines, base-rate matcher, calibration substrate) but does not classify into BULLISH / NEUTRAL / BEARISH and does not contribute to the 0-100 health score.

Release cadence

Derived same-day from FRED H.15 / TIPS par yields (lag 1).
