Sovereign all-time-high count (0-6)

What it is

Sovereign all-time-high count (0-6) — registry key sovereign_ath_count.

How many of the six long-end sovereigns are at an all-time high on their available history - the strict-extreme synchrony read. 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.

Source

Source module: sovereign_yields
Data source: computed

Derived metric — produced inside the platform (app/sources/sovereign_yields.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

Count over the same six-country set {us_30y, de_30y, ea_30y, uk_20y, ca_long, jp_30y} of how many are at an all-time high on their available macro_series history (the all_time_high flag from years_since_at_or_above -> years_since_window_high: no date strictly before the country’s trailing-one-month window was at or above its window high). NULL when no country in the set has history. See compute_sovereign_panel.

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

Recomputed each cycle from the six-country macro_series look-backs.
