Japan 30Y JGB yield

What it is

Japan 30Y JGB yield — registry key jp30y_yield.

Japan 30-year JGB yield (Japan MoF interest-rate CSV). Published on Tokyo time, so it lags the ET grid by about a day. long-end supply-stress carrier, Phase 2 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.

How it’s computed

Latest Japan 30Y JGB yield read back from the macro_series jp_30y series (Japan MoF JGB CSV, 30Y column; missing - dropped, CP932 footer skipped), rounded to 2dp. data_only carrier. See app/sources/sovereign_yields.py.

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

Japan MoF, business daily (Tokyo market); lags the ET grid by ~1 day.
