Forward contracts explained: fixed price, basis, pool, and options

The decision of when to sell grain gets most of the attention. The decision of how to sell it, which contract structure to use, gets far less, and it matters more than most farmers realise.

Different contract types allocate risk between you and the buyer in different proportions. Choosing the right structure is not about being clever; it is about understanding which risks you can manage and which ones you cannot, and pricing accordingly.

Fixed price contracts

A fixed price contract (sometimes called a flat price or outright contract) sets a specific AUD per tonne price for a specific quantity and delivery window. You agree today; you deliver grain at that price later.

What you lock in: everything, the futures price component, the basis component, the AUD/USD currency component.

What you give up: any upside if the market rises after you sign.

When it makes sense:

• You have a clear cost of production and the bid exceeds your breakeven by a margin you are comfortable with
• You have forward capital commitments (machinery, debt service) that require certainty
• The seasonal outlook is bearish, with La Niña driving expectations of a large national crop or the WASDE showing rising global stocks, and you expect prices to soften through harvest

GTA standard: Grain Trade Australia (GTA) Contract Standards cover fixed price grain contracts under their standard terms. Always ensure your contract references GTA standards or equivalent; a verbal or loosely-worded contract creates dispute risk.

Basis contracts

A basis contract splits the pricing decision into two separate actions. You lock the basis component today (the local cash price differential to futures) while leaving the futures component unpriced until you choose to fix it.

Cash price = futures price (fixed later) + basis (fixed today)

What you lock in: the local margin, your silo's delivered price relative to the global benchmark.

What you leave open: the futures price. If Chicago wheat rises after you sign the basis contract, you benefit from the full gain. If it falls, you bear the full loss.

When it makes sense:

• Local basis is historically firm and you want to capture it before it widens again at harvest
• You expect futures markets to strengthen (tightening WASDE balance, El Niño drought risk in major producing regions)
• You want to price in two steps, managing each component separately

Execution: You fix the futures component (called "pricing off") by nominating a specific futures contract month and instructing your buyer to price at market. Most buyers allow you to price off in tranches. The window to price off is specified in the contract.

AEGIC's grain marketing research highlights that basis contracts are most valuable when local basis is firm relative to historical norms. Capturing a strong local margin early, while leaving the global futures component open, is a disciplined approach to splitting a decision that is actually two separate risks.

Pool contracts

A pool or accumulation contract aggregates grain from multiple growers and prices it progressively over a defined window, often 12 months, to achieve an average price. Pool managers may use futures, options, and physical forward sales to construct the average.

What you lock in: participation in an averaging strategy. You receive the pool's weighted average price, less management fees.

What you give up: price certainty, and any ability to time your own sales. You also pay a management margin.

When it makes sense:

• You do not want to manage grain marketing decisions actively
• You have a large volume and want to avoid the execution risk of placing it all at one time
• The pool's historical average competes with or exceeds your flat price average; check this with data before committing

Watch the fee structure. Pool fees typically range from $2-6/tonne depending on the operator. In a year where the pool manager adds significant value through hedging, fees are well justified. In a flat, trending-down market, fees come directly out of your return with no corresponding benefit. Ask any pool operator for audited historical returns net of fees before committing tonnage.

Options (price floor contracts)

Some buyers and commodity trading houses offer price floor contracts, effectively allowing you to buy a put option on your grain. You pay a premium upfront (typically $3-8/tonne) and receive:

• A minimum floor price guaranteed regardless of how far the market falls
• Full participation in any upside above the floor

What you lock in: a worst-case price. If the market falls below the floor, you are protected. If it rises, you capture the move.

What you pay: the option premium. This is the cost of the insurance.

When it makes sense:

• You have significant production uncertainty (early in the season, before yield is established)
• You want to price inputs and plan cash flow against a floor without forfeiting upside
• The option premium is competitive relative to the value of the protection

Comparing costs: A $5/tonne option premium on 1,000 tonnes is $5,000. If the market falls $20/tonne below your floor, the option saved you $20,000. If the market rises $30/tonne, you captured that in full. The question is always whether the cost of the premium is worth the protection, given your risk tolerance and financial position.

How to think about combining structures

Professional grain marketing is rarely one contract type used exclusively. A structured approach might look like:

1. Pre-season: price 20-30% of expected production on flat price contracts when the bid covers cost of production plus a margin. This locks base revenue and removes existential risk.

2. Mid-season: use basis contracts for another 20-30% when basis is firm, leaving futures unpriced if the seasonal outlook is neutral or bullish.

3. Harvest: price the bulk of remaining grain flat or into the pool, accepting the harvest average on the portion that was not forward-priced.

4. Storage portion: if storing, use carry analysis (cost of carry vs. expected basis improvement) to decide when to sell, executing via flat price or basis as conditions warrant.

Research by the Grains Research and Development Corporation (GRDC) consistently shows that farmers who split their marketing across multiple price points achieve more consistent returns over time than those who wait for a single ideal price. The variance is lower even if the peak is not always captured.
