Chart 1: The Four-Product Dashboard
The chart below shows the four Snowtrail products during the 2021-22 winter squeeze, illustrating how weather risk, storage stress, and cross-basin LNG competition aligned during the crisis.
Key Insight
During the winter of 2021-22, both basins drew storage simultaneously while Russian pipeline flows declined. GLMI competition intensity moved into the Extreme regime as the US and Europe competed for the same LNG cargoes.
The chart below shows the four Snowtrail products during the 2021-22 winter squeeze, illustrating how weather risk, storage stress, and cross-basin LNG competition aligned during the crisis.
When both basins are stressed simultaneously, GLMI competition intensifies. This scatter plot shows the relationship between US and EU stress levels, coloured by GLMI competition intensity.
The table below shows the peak readings from each product during the Winter 2021-22 squeeze.
| Product | Metric | Peak Score | Peak Date | Peak Regime | Interpretation |
|---|---|---|---|---|---|
| WRSI | Forecast Uncertainty | 64.9 | 2022-01-01 | TRANSITION | Cold forecast with high model disagreement |
| GBSI-US | US Gas Stress | 81.0 | 2022-02-04 | HIGHLY_STRESSED | US storage draws accelerating |
| GBSI-EU | EU Gas Stress | 75.3 | 2021-12-05 | TIGHT | EU draws + Russian pipeline decline |
| GLMI | Basin Competition | 0.19 | 2022-01-01 | LOOSE_BALANCED | Both basins bidding for limited LNG |
The dual-basin scatter showed the relationship visually. Now we validate with bootstrap 95% CIs. If US and EU stress are genuinely correlated during the squeeze, the CI on the correlation coefficient should exclude zero.
| Basin | N | Mean Competition | Max Competition | Dominant Regime | Peak Intensity | Min Flexibility |
|---|---|---|---|---|---|---|
| AFRICA | 7 | 0.065 | 0.254 | LOOSE_BALANCED | LOW | 50.0 |
| ASIA_PAC | 7 | 0.065 | 0.254 | LOOSE_BALANCED | LOW | 50.0 |
| EU | 7 | 0.065 | 0.254 | LOOSE_BALANCED | LOW | 43.4 |
| LNG | 7 | 0.065 | 0.254 | LOOSE_BALANCED | LOW | 50.0 |
| MENA | 7 | 0.065 | 0.254 | LOOSE_BALANCED | LOW | 50.0 |
| US | 7 | 0.065 | 0.254 | LOOSE_BALANCED | LOW | 51.7 |
Regime labels show the current level of market stress, while the direction signal indicates whether conditions are tightening or easing. If both GBSI-US and GBSI-EU were in TIGHTENING direction simultaneously, that's the highest-conviction signal for cross-basin stress. Combined with GLMI competition escalation, it creates a three-signal confluence.
| Product | Direction | N | % of Peak Winter | Avg Score |
|---|---|---|---|---|
| GBSI-US | TIGHTENING | 3 | 23% | 76.4 |
| GBSI-US | STABLE | 4 | 31% | 67.8 |
| GBSI-US | LOOSENING | 6 | 46% | 56.9 |
| GBSI-EU | TIGHTENING | 4 | 4% | 61.6 |
| GBSI-EU | STABLE | 67 | 74% | 63.7 |
| GBSI-EU | LOOSENING | 19 | 21% | 62.6 |
The winter squeeze was the first event where all four Snowtrail products fired in concert. Here is what each told you that price alone could not:
| Product | Signal State | What It Meant |
|---|---|---|
| WRSI | TRANSITION with persistent cold tails | Demand shock incoming. Models disagreed on severity, creating forecast uncertainty |
| GBSI-US | TIGHTENING direction, elevated score | US storage draws accelerating. Domestic supply under pressure independent of EU dynamics |
| GBSI-EU | TIGHTENING direction, sustained TIGHT regime | EU storage draws compounded by declining Russian pipeline flows. This reflected a structural shortage rather than a temporary weather spike |
| GLMI | Competition EXTREME, flexibility collapsing | Both basins bidding for marginal LNG cargoes. Zero-sum game with no slack in the system |
The critical insight is simultaneous tightening across basins. When both GBSI-US and GBSI-EU show TIGHTENING direction at the same time, GLMI competition becomes the binding constraint. This is the signal combination that distinguishes a regional cold snap (one basin tightens, the other absorbs) from a global squeeze (both tighten, LNG cannot arbitrage the difference).
Without this cross-product view, a US gas trader would have seen domestic tightening but missed that the EU was also pulling LNG supply. An EU trader would have seen TTF rising but not understood why LNG relief was not arriving. Snowtrail connects both sides.
This signal combination historically corresponds to:
The key signal to monitor is GLMI competition intensity. When this moves into the Extreme regime while both GBSI-US and GBSI-EU tighten simultaneously, historical episodes show price dislocations across global LNG benchmarks. Dual-basin TIGHTENING with EXTREME competition has occurred in only one episode, making it the highest-conviction regime combination in the dataset.
Winter 2021-22 was the first test of the post-Russia global gas market. Both the US and EU were drawing storage simultaneously while Russian pipeline flows to Europe were declining. LNG became a zero-sum game. Every cargo that went to Europe didn't go to Asia, and vice versa.
The direction analysis reveals whether stress was building or already priced in during the squeeze. When both basins show TIGHTENING direction simultaneously, that's the highest-conviction signal for cross-basin competition.
Global Macro PM / Hedge Fund: - Dual-basin TIGHTENING = highest-conviction trade: long EU gas, long US gas, short LNG shipping (supply becomes constrained for both) - GLMI competition at EXTREME = spread trades collapse. Go flat on JKM-TTF arb - When one basin shows LOOSENING while the other is TIGHTENING = relative value trade between HH and TTF - Position sizing: use the US-EU correlation to size the cross-basin hedge
LNG Portfolio Manager: - GLMI EXTREME = every cargo is contested. Maximize spot optionality, defer fixed commitments - Dual-basin TIGHTENING = cargo diversions from Asia to EU accelerate. Re-optimize shipping routes immediately - WRSI TRANSITION + dual-basin stress = weather multiplier incoming. Pre-position
Risk Manager / Utility Procurement: - Dual-basin TIGHTENING = procurement costs rising globally. Accelerate forward hedging across both HH and TTF - GLMI competition HIGH/EXTREME = LNG delivery reliability drops. Activate contingency supply agreements - When LOOSENING appears in either basin = procurement window opening. Execute
When both hemispheres are cold simultaneously, LNG becomes a zero-sum game. Snowtrail tracked stress building in both basins through the direction signal and showed the competition for marginal supply in real-time through GLMI. No other product provides this connected, cross-basin view.
