DHHNGSP). Waha / TTF / JKM as of Uranium — production geography (the locality lens)
Uranium is the cleanest specific-access commodity in the Energy pillar — only 16 countries produce it commercially, and the geography map onto the multi-polar fracture line directly. Western utilities cannot build their fuel cycle from one-side-only sources for long.
Methodology
The Energy Regime Index operationalizes the Kilian (2009, AER) decomposition of oil-market shocks into three distinct channels — supply, aggregate demand, and precautionary (forward-looking) demand. Each component is a free-data proxy for one channel:
| Component | Proxy | Channel |
|---|---|---|
| Brent – WTI spread | BZ=F − CL=F monthly close |
Oil-specific supply / geopolitical stress — wider spreads reflect Mideast and logistics risk premia over US shale |
| Copper / Gold YoY | HG=F / GC=F monthly ratio, 12-month % change |
Aggregate demand — industrial metal vs. safe haven isolates the demand component from monetary effects |
| OVX | ^OVX monthly close |
Precautionary uncertainty — the options market's ex-ante distribution of crude prices |
Z-score convention. Each component is standardized with an expanding-window mean/std (minimum 24 months). The z at date $T$ uses only data through $T$ — same discipline as the BCI scorer. No look-ahead contamination.
Sign alignment. All three components are oriented so higher z = more stress: Brent–WTI wider (+), Copper/Gold YoY weaker (–, sign flipped), OVX higher (+).
Composite: $z^{\text{stress}}_t = \tfrac{1}{3}(z^{BW}_t - z^{CG}_t + z^{OVX}_t)$ — equal-weight. (Equal weights are a deliberate choice against overfitting factor loadings on a 3-component sample; when a larger data feed lands, a DFM-style loading estimation becomes viable.)
Phase classification.
- $z < -0.5$ → CALM
- $-0.5 \le z < 0.5$ → NORMAL
- $0.5 \le z < 1.5$ → ELEVATED
- $z \ge 1.5$ → STRESS
What's in v1, what's in v2
The originally scoped 7-component composite (adding TTF natural gas, Baltic Dry Index, Brent term structure, oil-producer GPR country detail, and Urals/WCS regional discounts) is deferred. Reason: the missing components are subscription-gated (Platts, ICE) or involve more complex data plumbing (full futures curve, GPR country microdata) — shipping them half-sourced would contaminate the index. The v1 composite lives on data that is free, robust, and directly maps to Kilian's decomposition.
Revisit once revenue supports a real commodity-data subscription; the v2 upgrade should land as one coordinated release with methodology-change notes, not drip-fed additions.
Canon
Kilian (2009, AER) — oil supply/demand/precautionary decomposition; Hamilton (2003, J. Econometrics) — oil-price nonlinearity and recession identification; Stock & Watson (2002, JBES) for expanding-window z-score discipline inherited from the BCI.
Inflation pipeline
Energy is the first stage of the producer-price → consumer-price inflation pipeline. WTI YoY enters PPI within ~1 month and feeds CPI YoY at ~3-6 months. The downstream nowcast lives on the Inflation Nowcast page — a 2-input composite (PPI + core PCE 6m annualized) calibrated by 60-month rolling-origin OLS at +0.88 OOS correlation. When Energy stress is elevated, the inflation nowcast tends to move higher 3-6 months later.
