UK 20Y long yield

What it is

UK 20Y long yield — registry key uk20y_yield.

UK 20-year long par yield (Bank of England IADB IUDLNPY) - the UK long end. There is no clean free daily UK 30Y, so the 20Y long par series is the reported UK long end. 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 UK 20Y long par yield read back from the macro_series uk_20y series (Bank of England IADB IUDLNPY, _iadb-fromshowcolumns.asp CSV export), rounded to 2dp. 20Y is the UK long end (no clean free daily 30Y). 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
