Energy Market Correlations and Spreads
Energy markets are interconnected. Understanding the relationships between crude oil, natural gas, gasoline, and heating oil unlocks spread trading opportunities.
Key Energy Spreads
The Crack Spread
- Difference between crude oil price and refined product prices
- Measures refinery profitability
- 3:2:1 ratio: 3 barrels crude = 2 barrels gasoline + 1 barrel heating oil
- Widening crack spread = strong product demand (bullish for refiners)
- Narrowing crack spread = weak demand or oversupplied products
WTI-Brent Spread
- Difference between US and international crude benchmarks
- Normally Brent trades at premium to WTI
- Spread widens when US has excess supply
- Spread narrows when US exports increase
- Reflects transportation and quality differences
Calendar Spreads
- Price difference between different delivery months
- Contango: Future months more expensive (normal, storage cost)
- Backwardation: Near months more expensive (supply tightness)
- Backwardation signals very tight market conditions
Cross-Commodity Correlations
Oil and Natural Gas
- Historically correlated (both energy sources)
- Correlation has weakened in recent years
- US shale revolution disconnected the two
- Gas-to-oil ratio historically around 6:1
- When ratio diverges significantly, mean reversion trades emerge
Oil and the US Dollar
- Strong inverse correlation (oil priced in USD)
- Dollar strength = headwind for oil prices
- Dollar weakness = tailwind for oil prices
- Trade: Use DXY direction as a filter for oil trades
Oil and Equity Markets
- Positive correlation with energy stocks (XLE, OIH)
- Oil often leads energy stocks by 1-2 days
- Extreme oil moves affect broader market sentiment
- Oil crash = risk-off; Oil rally = risk-on (usually)
Oil and Commodity Currencies
- CAD (Canada), NOK (Norway), RUB (Russia)
- USD/CAD inversely correlates with oil
- Oil rally = CAD strength = USD/CAD decline
- Trade oil through USD/CAD for lower volatility exposure
Spread Trading Strategies
Seasonal Crack Spread
- Gasoline crack widens March-June (pre-driving season)
- Heating oil crack widens September-December (pre-winter)
- Trade the seasonal pattern with spread positions
- Lower risk than outright directional trades
Contango/Backwardation Trades
- When market shifts from contango to backwardation = bullish signal
- When backwardation collapses to contango = bearish signal
- Trade the front month in the direction of the structure change
- Use calendar spread shape as a leading indicator
Cross-Commodity Pairs
- Oil/Gas ratio mean reversion
- Gold/Oil ratio (normally 15-25 barrels of oil per oz of gold)
- Copper/Oil ratio (economic growth indicator)
- Extreme divergences tend to correct
Real-World Application
Daily Checklist for Energy Traders
- Check crude oil inventories (EIA Wednesday)
- Check natural gas storage (EIA Thursday)
- Monitor DXY for dollar influence
- Review refinery utilization data
- Check OPEC compliance and production data
- Review tanker rates for shipping demand
- Monitor geopolitical headlines (Middle East, Russia)
Position Management
- Energy correlations break down during crises
- Reduce position sizes during OPEC meetings
- Be aware of expiration and rollover for futures
- Spread positions have lower margin requirements
Key Takeaways
- Energy markets are deeply interconnected through supply chains
- Crack spreads measure refinery profitability and product demand
- Backwardation vs contango reveals market tightness
- USD/CAD is a lower-volatility way to trade oil
- Spread trading reduces risk compared to outright positions
