Submit Your BidGrain basis is the difference between the local elevator cash bid and the nearby CBOT futures contract. For Janesville, Rock County, the basis reflects transportation costs to export terminals, local supply and demand balance, and elevator margin.
A strengthening basis (moving toward zero or positive) means local demand is increasing relative to futures — elevators are bidding more aggressively for your grain. A weakening basis means local supply is ample or export demand has softened.
Factors that affect Janesville area basis include: proximity to river export terminals, local processor demand (ethanol, crush, livestock feeding), seasonal harvest pressure, and freight costs from this location to terminal markets.
| Basis Signal | What It Means | Marketing Implication |
|---|---|---|
| Basis narrows (strengthens) | Local demand exceeding local supply; elevator bidding up | Good time to sell — local pricing is strong relative to futures |
| Basis widens (weakens) | Local supply ample; elevator has less urgency to buy | Consider storing if carry is positive on futures — wait for demand signal |
| Basis vs. 5-yr average | Compare current basis to historical seasonal pattern | If current basis is stronger than average, seasonal advantage may not persist |
