Tools that split the decision
The grain trade built contracts specifically to separate the two halves. A hedge-to-arrive contract locks futures and leaves basis open; use it when futures look good but basis is weak, typically in summer for harvest delivery. A basis contract does the reverse, locking basis and leaving futures open; use it at harvest when basis is historically wide but you think the board will recover. Delayed price contracts hand over the grain with nothing set, which is pure speculation in work clothes. None of these are free; each embeds a cost or a risk. But used deliberately, they let you sell each half of your price at its own best time.
The two halves of your price
Every cash grain price has two parts: the futures price and the basis. You can lock the futures part with a hedge or a forward contract that references futures, but until you set the basis, your final price is still open. Basis is quoted as over or under the relevant futures month, like 20 under December.
Basis is local. It reflects how much grain is available near you, what the freight cost is to the nearest demand point, how hard local elevators and processors are bidding, and how full the bins are. Two producers fifty miles apart can face very different basis on the same day.
What moves basis
- Harvest pressure. Basis typically weakens, meaning goes more negative, when everyone delivers at once and storage fills up.
- Transportation. Freight rates, river levels, rail costs, and fuel prices all feed into local basis.
- Local demand. A new ethanol plant, crusher, or export terminal tightens basis for miles around.
- Farmer selling. When producers hold grain, buyers bid basis up to pry it loose. When producers sell heavily, basis slips.
Managing the basis half
Basis has its own calendar. It is usually weakest at harvest and strongest in spring and summer when supplies tighten. That is why selling futures at harvest and setting basis later, or using basis contracts and hedge-to-arrive contracts to separate the two decisions, can add real money over time. Know your local basis history, not just the futures chart. Multi-year basis records from your elevator are some of the most valuable marketing data you can collect.
