🛢️ Natural Gas Price
Overview
Daily spot prices for three U.S. natural gas hubs: Henry Hub, SoCal Citygate, and Chicago Citygate, from 2019–2022.
Data Structure
| Metric | Value |
|---|---|
| Hubs | Henry Hub, SoCal Citygate, Chicago Citygate |
| Granularity | Daily spot prices |
| Time Period | 2019–2022 |
| Flagship Event | February 2021 Texas freeze (prices spiked 100× at some hubs) |
Causal Reasoning Model
Three diagnostic pathways trace price anomalies to their root causes:
1. Weather Extremes: polar vortex → heating demand surge → price spike 2. Pipeline Constraints: hub spread divergence reveals supply bottlenecks 3. Supply Disruption: production freeze-offs during extreme cold
The Texas Freeze
The February 2021 event is the flagship diagnostic case: extreme cold knocked out gas production across Texas, demand for heating surged simultaneously, and prices spiked 100× at some hubs, a perfect storm traced through all three causal pathways.
