Brent–WTI spread

What it is

Brent–WTI spread — registry key brent_wti_spread.

Brent minus WTI front-month spread; curve-structure / global-vs-domestic crude differential proxy.

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: energy
Data source: back_fillable

Fetched directly from app/sources/energy.py; see source code for the upstream API call and any provider-specific handling.

How it’s computed

brent_close − wti_close, rounded to 2dp. See app/sources/energy.py:98.

Where it surfaces

• API field: energy.brent_wti_spread on GET /api/v1/signals/latest
• Surface: daily_signals row (daily-cadence persistence)
• Surface: /signals/sparklines (UI sparklines)
• Surface: change markers in the rendered report

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.
