Grain prices whipsawed all July - and a farmer's hardest call is when to sell
December corn futures ran from $5.06 to $4.26 and back near $4.92 in ten weeks, while soybeans slid and wheat climbed on Black Sea shipping risks. The swings show why a grower's real gamble is not the harvest but the price it fetches.
Key takeaways
- December corn futures swung about 80 cents a bushel in ten weeks - from $5.06 down to $4.26 and back near $4.92 - as heat, drought and rain forecasts fought over the size of this year's crop.
- Wheat rose while corn and soybeans fell, because Black Sea shipping disruptions tightened the global grain pool even as US supply looked ample.
- The swings are landing at the till as "burgerflation" and shrinking packets, while grain-trading middlemen like Bunge profit from the very volatility that unsettles farmers.
The grain markets could not sit still
American grain futures spent July lurching in both directions, and the calendar tells the story. The December 2026 corn contract is the price locked in now for corn delivered this fall. It peaked at $5.06 a bushel on May 13, then slid to $4.26 by June 30
A futures price is simply the price agreed today for a crop delivered on a set future date. It lets buyers and sellers trade a harvest that does not yet exist. By late July the market had swung roughly 80 cents a bushel in ten weeks. That is about a sixth of the crop’s value, and not a single ear of corn changed hands
Soybeans told a harsher version of the same story. On July 27, November soybean futures opened down about 41 cents at roughly $12.12 a bushel, corn near $4.74, and September wheat near $6.73
Wheat went the other way - because of a war
While corn and soybeans sagged, US wheat rose late in the month on disruptions around the Black Sea
The split makes the point that grain is a commodity - a bulk good priced as one interchangeable pool worldwide, so a shortage anywhere moves the price everywhere. A US wheat farmer in Kansas can watch the price of a crop already in the field jump because of drones over a port five thousand miles away. Nobody in that chain chose the swing; it simply arrived.
The squeeze reaches the plate
The volatility upstream is landing at the till. In the UK, the cost of a barbecue has been dubbed “burgerflation”: beef, buns and bagged salad have all risen sharply since last summer. Yet cattle farmers say they are not the ones cashing in
The big food names are passing costs on. Unilever, maker of Marmite and Dove, warned of price rises as its own costs climb
Not every trader is losing. Bunge is one of the giant middlemen that buy, ship, crush and sell the world’s grain and oilseeds. It beat second-quarter estimates on strong crush margins and raised its 2026 outlook
The quiet story: the weather that sets it all
Underneath the price charts sits the thing no contract controls. More than half of England is now officially in drought
That uncertainty is the whole game. A farmer plants in spring, spends all summer at the mercy of the sky, and cannot know in July what the crop will be worth in November. The futures market exists precisely because that not-knowing is unbearable to plan around - and someone, somewhere, is willing to take the other side of the bet.
02 · Lesson · why it matters
The trade a farmer makes to stop guessing
A futures contract lets a grower swap an unknown future price for a certain one - handing the swing's risk to someone who wants it.
A crop worth eighty cents less by lunchtime
A corn farmer in Iowa planted in April. The crop will not come off the field until October. In between sits a summer of weather no one controls. And in between sits a price that moved about eighty cents a bushel in ten weeks. It ran up to $5.06 in May, down to $4.26 in June, back near $4.92 in July, then down again on a rain forecast.
The farmer’s real gamble is not whether the corn grows. It is what the corn will be worth when it does. A good harvest at a bad price can pay less than a poor harvest at a good one. And the price is set far from the field - by a heatwave in Europe, drones over a Black Sea port, a rain cloud over the wrong part of the Midwest.
That is an unbearable thing to plan a business around. So a market grew up to fix it.
The price you agree to before the thing exists
A futures contract is a promise made today to buy or sell a set amount of a crop, at a set price, on a set future date. The corn does not exist yet. The price does.
That small trick changes everything. In May, with December corn at $5.06, the farmer could sell a futures contract - promise to deliver corn in December at that price - and lock it in. When the price then fell to $4.26, it did not matter. The farmer had already agreed to $5.06. The swing happened to someone else.
This is the whole point of the market, and it is why it is not gambling. The farmer is doing the opposite of gambling. A grower faces a risk they never chose - the price swing - and pays to get rid of it. They trade an uncertain number for a certain one, on purpose, to be able to sleep.
Risk does not vanish - it moves
Here is the part that is easy to miss. When the farmer locks in $5.06, the risk of the price falling does not disappear. It cannot. It moves to whoever took the other side of the contract.
That other side might be a cereal company that needs corn in December and fears the price rising. Two people with opposite fears, each glad to be rid of their own. Or it might be a speculator: someone with no field and no factory, who simply wants the swing. They bet the price will move their way, and are paid, in effect, to carry a risk the farmer wanted gone.
We tend to hear “speculator” as a villain. But look at what they actually do here. They stand ready to take the risk the farmer is desperate to shed. Without someone willing to hold the swing, the farmer would have no one to sell certainty to. The gambler and the person avoiding a gamble need each other.
The lock cuts both ways
Certainty has a price, and it is not money - it is the upside. The farmer who locked in $5.06 in May was protected when corn fell to $4.26. But if corn had instead run to $6.00, that farmer would still deliver at $5.06 and watch the extra dollar go to the other side.
A hedge is not a way to win. It is a way to stop the outcome from depending on luck. You give up the best case to be rid of the worst. The neighbour who did not hedge kept the chance of $6.00 corn - and kept the chance of $4.26 corn too. One of them traded the range for a point. The other kept the whole range, good and bad.
There is no free version. Whoever holds the swing - farmer, cereal maker, or speculator - is exposed to it. The contract only decides who.
Everyone is quietly on one side of a lock
This is not a farmer’s problem. It is the shape of every choice made against an unknown price, and most of us are on one side of it without a contract to show for it.
The household on a fixed-rate mortgage has locked its housing cost and handed the interest-rate swing to the bank. The one on a variable rate kept the swing - and the chance of paying less, and the chance of paying more. A salaried worker traded the upside of a good year for a steady wage; the person on commission kept the swing. A long supermarket contract that steadies the price of bread is a hedge you eat.
The grain market just makes visible a bargain we strike everywhere. Certainty is worth paying for; the payment is the upside you give up; and the risk you shed does not die, it lands on someone who wanted it. Seen whole, the farmer sweating the July forecast, the trader betting against them, and the shopper at the till are not three separate stories. They are three seats around the same swinging price, and no seat can see the others’ fear.

Lock It or Ride It
Rehearse hedging a crop: lock in a futures price to shed the swing, and feel the upside you give up and who takes the risk.
04 · Hope · carry this
Long before anyone could tame the weather, farmers found a way to share its risk with strangers who were glad to carry it. The uncertainty never went away - but we got better at helping each other bear it.
