Commodity Spread Trading
Spread trading involves simultaneously buying one commodity contract and selling a related one. This strategy reduces directional risk while profiting from changing price relationships.
Types of Commodity Spreads
Intra-Commodity (Calendar) Spreads
- Buy one month, sell another month of the SAME commodity
- Example: Buy July Corn, Sell December Corn
- Profit from changes in the term structure
- Lower margin requirements than outright positions
- Reduced directional risk
Inter-Commodity Spreads
- Buy one commodity, sell a related one
- Example: Buy Soybeans, Sell Corn (Soy-Corn ratio)
- Based on substitution or production relationships
- Profit from one outperforming the other
Location Spreads
- Same commodity, different delivery locations
- Example: WTI vs Brent Crude Oil
- Profit from regional supply/demand imbalances
- Transportation cost changes
Processing Spreads
- Raw material vs finished product
- Crack Spread: Crude oil vs gasoline and heating oil
- Crush Spread: Soybeans vs soybean oil and meal
- Spark Spread: Natural gas vs electricity
Why Trade Spreads
Risk Reduction
- Both legs move with the overall market
- Only profit or lose on the DIFFERENCE
- Significantly lower volatility than outright positions
- Margin requirements are often 50-80% lower
More Predictable
- Spread relationships tend to revert to mean values
- Seasonal patterns in spreads are more reliable
- Less affected by sudden geopolitical events
- Fundamentals drive spreads more than speculation
Professional Approach
- Most professional commodity traders are spread traders
- Hedge funds and commercial traders primarily trade spreads
- Higher Sharpe ratios than directional trading
- More consistent returns over time
Key Spread Relationships
Crack Spread (Energy)
- 3:2:1 Crack: 3 barrels crude = 2 barrels gasoline + 1 barrel heating oil
- Widens when refining demand is high (summer)
- Narrows when crude supply is tight
- Major refiners hedge using this spread
Crush Spread (Agriculture)
- Soybeans vs soybean oil and soybean meal
- Profit margin for soybean processors
- Widens when processing demand exceeds supply
- Key indicator of agricultural market health
Gold-Silver Ratio
- Number of silver ounces to buy one ounce of gold
- Historical mean: approximately 65
- Above 80: Silver is cheap relative to gold
- Below 50: Silver is expensive relative to gold
- Trade the reversion to mean
Risk Management for Spreads
- Spreads have lower risk but can still lose money
- Use stop losses on the spread value, not individual legs
- Position size based on the spread's volatility, not individual contract volatility
- Monitor both legs for unusual behavior
- Be aware of liquidity differences between legs
Key Takeaways
- Spread trading reduces directional risk significantly
- Professional commodity traders primarily trade spreads
- Calendar, inter-commodity, and processing spreads each have unique characteristics
- Spread relationships are more predictable than outright prices
- Lower margin and lower risk make spreads ideal for developing traders
