How Grain Futures Markets Support Physical Hedging
Grain futures markets support physical hedging by allowing businesses that own grain, expect to produce it or need to buy it later to take an opposing position in the futures market. An adverse price move in the physical market can then be partly offset by a gain on the futures position. A farmer holding a crop sells futures to protect against falling prices; a mill or feed manufacturer that will need grain buys futures to protect against rising prices. In both cases, the aim is to replace outright price risk with basis risk, which if often smaller and less volatile depending on the local cash market dynamics. This article explains how short and long hedges work, how basis and convergence affect the result, when cross-hedging is used, and what businesses need to consider after placing a hedge.

The core hedging mechanism: an opposite position
Hedging involves taking a futures position that is opposite to the physical, or cash, exposure. Cash and futures prices for the same grain tend to move broadly in the same direction because they respond to many of the same supply and demand factors. This allows a gain in one market to offset at least part of a loss in the other.
Physical exposure | Main price risk | Futures hedge | Hedge normally closed when |
|---|---|---|---|
Producer or elevator holding or expecting to sell grain | Prices fall | Short hedge: sell futures | The physical grain is priced or sold |
Processor, feedlot or importer expecting to buy grain | Prices rise | Long hedge: buy futures | The physical grain is priced or purchased |
The rule of thumb: if your eventual action is to sell in the cash market, hedge today by selling futures; if your eventual action is to buy in the cash market, hedge today by buying futures.
The short hedge, worked through
Say it's March and a wheat producer plans to sell to the local elevator in mid-June. July wheat futures are trading at $6.50 per bushel, and the cash price in the producer's area in mid-June is normally about 35 cents under the July futures price, a basis of −$0.35. The producer sells July futures now, aiming for an approximate price of $6.15 per bushel ($6.50 futures minus the 35-cent basis).
If the producer expects to sell 10,000 bushels, the hedge would represent two standard 5,000 bushel CBOT Chicago Wheat futures contracts.
If futures fall to $6.00 by June and the basis holds at 35 cents under, the producer sells cash wheat at $5.65 and buys back the futures position for a 50 cent gain. The net selling price is $6.15 before transaction costs, matching the original target because the basis was unchanged. Once the quantity and timing of the futures hedge are aligned with the physical sale, the main source of difference from the target is basis:
Final basis | Cash price when futures are $6.00 | Futures gain | Net selling price |
|---|---|---|---|
$0.30 under | $5.70 | $0.50 | $6.20 |
$0.35 under | $5.65 | $0.50 | $6.15 |
$0.40 under | $5.60 | $0.50 | $6.10 |
The long hedge, worked through
A commodities buyer uses the same mechanism in reverse. Take a corn importer expecting to buy in June. In March, CBOT July corn futures are trading at $3.93 per bushel. The importer buys July futures to protect the futures component of the eventual purchase price.
By June 14, assume for simplicity that both the local cash price and July futures have fallen to $3.63. The importer buys the physical corn at the lower cash price but closes the long futures position at a loss of $0.30 per bushel. Before transaction costs, the futures loss offsets the reduction in the cash price, producing a net purchase cost of $3.93. If both prices had risen by the same amount, the higher cash cost would have been offset by a futures gain. A hedge is intended to make the commercial result more predictable, not to produce a windfall. In practice, the final cost will also reflect basis and execution costs.
Grain futures hedging example: a 5,000-tonne wheat position
This anonymised example took place in June 2026, leading into harvest for the 2026/27 marketing year. A grain trader had an opportunity to sell 5,000 tonnes of feed wheat FCA Ravenna at €218 per tonne. The Ravenna cash price had fallen from more than €225 per tonne during the previous two weeks, but the trader did not want to lose the customer.
Because the wheat still needed to be purchased, the sale left the trader exposed to a recovery in physical prices. To manage that risk, the trader bought December Euronext Milling Wheat futures at €213.93 per tonne. With the Ravenna cash price at €218, the starting basis was €4.07 over futures.
Each futures contract represented 50 tonnes, so the trader bought 100 contracts to cover the 5,000-tonne physical position.
Futures fell through June and into July. As the position was marked to market, the trader had to lodge additional funds to maintain it. Prices later rose as the market responded to smaller-than-expected European crops and concerns about Russian and Ukrainian wheat supplies in the export market.
When the hedge was closed, the Ravenna cash price had risen to €230 per tonne and December futures had reached €235.38.
Position | Entry | Exit | Result |
Physical wheat | Sold at €218/t | Purchased at €230/t | −€60,000 |
December wheat futures | Bought at €213.93/t | Sold at €235.38/t | +€107,250 |
Basis | +€4.07/t | −€5.38/t | Weakened by €9.45/t |
Combined physical and futures result | +€47,250 before fees | ||
Trading, clearing and exchange fees | −€1,000 | ||
Result after fees | +€46,250 |

The fees were equivalent to €0.20 per tonne. The hedge produced a positive result because the basis weakened by €9.45 per tonne: the futures gain was greater than the increase in the cost of purchasing the physical wheat.
The example also shows why margin planning matters. Although the hedge ultimately generated a gain, the trader still needed additional cash when futures fell through June and into July.
