Seasonality is fundamental to agricultural commodity trading. Understanding crop cycles and their price impacts provides trading opportunities throughout the year.
What is Agricultural Seasonality?
Definition
Concept:
- Recurring patterns based on crop cycles
- Weather-related price movements
- Demand fluctuations
- Predictable tendencies
Why It Matters
Trading Implications:
- Historical patterns repeat
- Positioning opportunities
- Risk awareness
- Strategic planning
The Agricultural Calendar
Northern Hemisphere
Key Periods:
- Spring: Planting season
- Summer: Growing season
- Fall: Harvest season
- Winter: Storage/marketing
Southern Hemisphere
Opposite Timing:
- September-November: Planting
- December-February: Growing
- March-May: Harvest
- June-August: Marketing
Grain Seasonality
Planting Season (Spring)
Characteristics:
- Uncertainty premium
- Weather concerns
- Acreage decisions
- Price volatility
Trading Implications:
- Prices often rise pre-planting
- Weather delays add premium
- Planting progress matters
Growing Season (Summer)
Characteristics:
- Weather premium peak
- Critical development stages
- Drought/flood concerns
- Maximum uncertainty
Trading Implications:
- July-August most volatile
- Weather forecasts critical
- Position for conditions
Harvest Season (Fall)
Characteristics:
- Supply becomes known
- Harvest pressure
- Prices typically fall
- Yield clarity
Trading Implications:
- Harvest pressure shorts
- Basis weakens
- Volume increases
Post-Harvest (Winter)
Characteristics:
- Storage period
- Demand focus
- Export activity
- Carry costs
Trading Implications:
- Supply known
- Demand drivers matter
- Export competition

- Nearby vs deferred
- Seasonal carry patterns
- Lower risk strategy
Inter-Commodity Spreads
Examples:
- Corn vs soybeans
- Wheat vs corn
- Seasonal ratio changes
- Acreage competition
Limitations of Seasonality
Not Guaranteed
Reality:
- Patterns don't always repeat
- Fundamentals can override
- Unexpected events occur
- Use as guide, not rule
Current Conditions Matter
Consider:
- This year's supply/demand
- Weather conditions
- Policy factors
- Global events
Practical Application

Steps:
- Study each commodity
- Note key dates
- Track historical patterns
- Monitor current year
Calendar Creation
Mark:
- Planting windows
- Critical growth stages
- Harvest periods
- Report dates
Position Management
Approach:
- Enter with seasonal tendency
- Confirm with fundamentals
- Use stops appropriately
- Exit when pattern completes
