Overview
This lecture reviews the functions and economic significance of grain elevators in agricultural markets, explaining their role in storage, logistics, and price discovery.
Purpose and Role of Grain Elevators
- Grain elevators are facilities for the storage and handling of grain crops after harvest.
- They serve as the first point of sale for many grain producers.
- Elevators aggregate grain from multiple farmers, enabling efficient transport to processors or export markets.
- They maintain grain quality through conditioning, cleaning, and drying.
Grain Elevator Operations
- Elevators buy grain from farmers at current market prices called “cash prices.”
- They may offer forward contracts, allowing farmers to lock in prices for future delivery.
- Grain is graded upon delivery to determine quality and price adjustments.
- Elevators must manage inventory risk due to fluctuating market prices.
Grain Marketing and Price Discovery
- Elevators use hedging in futures markets to manage price risk between buying from farmers and selling to end users.
- Basis is the difference between local cash price and the futures price; it reflects storage, transport, and local supply/demand.
- Basis can fluctuate seasonally and with local market conditions.
Economic Importance
- Elevators facilitate market liquidity by enabling year-round sales, not just at harvest.
- Their logistics support efficient movement from farm to global markets.
- By aggregating shipments, elevators help reduce per-unit transportation costs.
Key Terms & Definitions
