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

1. Spreads have lower risk but can still lose money
2. Use stop losses on the spread value, not individual legs
3. Position size based on the spread's volatility, not individual contract volatility
4. Monitor both legs for unusual behavior
5. Be aware of liquidity differences between legs

Key Takeaways

1. Spread trading reduces directional risk significantly
2. Professional commodity traders primarily trade spreads
3. Calendar, inter-commodity, and processing spreads each have unique characteristics
4. Spread relationships are more predictable than outright prices
5. Lower margin and lower risk make spreads ideal for developing traders
