Good morning, Farm Nation, and Hello Truck City. This is FarmTale's Unplugged Daily Farm Brief with a special weekend bonus edition brought to you by World TradeX, empowering farmers. I'm Rick Fortanova. Our daily show brings you farm news, current events, egg tech, markets, and a visit to the old farmer's almanac. Today we're slowing down a little and spending the whole show on one subject: understanding the grain market. We'll start with a farmer who has corn to sell and somebody who needs to buy it. We'll follow their decisions one step at a time. And if you enjoy this show, would you give us a follow, a like, or a share? That would be fantastic. So grab your coffee and fire up whatever you're driving, and let's learn about the grain market. Why do we need a grain market? Imagine a farmer named Sam. He's our made-up farmer for the day, and all our prices are examples. Sam grows corn. A livestock farmer needs corn to feed her animals, an ethanol plant needs corn to make fuel. They need to find a way to find each other and agree on a price. That's what the market does. A market can be people dealing directly with each other or buyers and sellers meeting through a computer system. Suppose Sam has a load of corn and three buyers want it. One buyer might offer a little more to get that load. Now, suppose lots of farmers have corn to sell and the buyers already have nearly everything they need. Those buyers may offer less. The price comes from those offers and the deals people actually agree to. Nobody at the exchange simply decides what every farmer's corn should be worth. An exchange is an organized marketplace. It provides the trading system and the rules. So what makes prices go up and down? You'll hear people talk about supply and demand. Supply means how much corn is available. Demand means how much corn buyers want and are willing to pay for. If drought damages a large part of the crop, there may be less corn to go around. Buyers competing for that smaller supply can push prices up. If growing conditions are good and farmers harvest a huge crop, there may be more corn than buyers urgently need. That can push prices down. Buying can change too. An ethanol plant might increase production and need more corn. Livestock producers might need more feed. Customers overseas might place bigger orders. Those purchases can help support prices. If customers buy less, prices can come under pressure. And it's a worldwide business. A big crop in another country gives buyers another place to shop. People also act on what they think is about to happen. A forecast for damaging heat can move prices before the heat arrives. If rain later improves the outlook, prices may move back down. That helps explain why prices can change while Sam's corn is still standing in the same field. The market is responding to new information about how much grain people expect to have and need. Now, this is why Sam needs to think ahead. Sam plants in spring and expects to harvest in fall. He pays for seed, fertilizer, and other expenses long before he sells the crop. Suppose he figures that a selling price around $4.70 a bushel would work for his business. A bushel is a unit for measuring grain. Think of corn priced by the bushel the way gasoline is priced by the gallon. Sam's worry is that by harvest the price might be much lower. The livestock farmer has the opposite worry. She needs corn later and she's concerned the price might rise. Both want a way to make plans before the corn changes hands. Futures contracts give them one way to manage that uncertainty. So, what is a futures contract? A contract is an agreement that carries obligations. A corn futures contract is an agreement to buy or sell a set amount of corn for a specified delivery month at an agreed price today. The exchange sets standard rules, including the amount of corn and the quality. One standard corn contract covers 5,000 bushels. For our example, Sam sells one December corn futures contract at $5 a bushel. He is the seller side of that agreement. Somebody else takes the buyer's side. The word December identifies the contract's delivery month. It does not mean $5 is a prediction guaranteed to come true in December. It means $5 is the price agreed upon when Sam makes this trade. And Sam does not receive payment for $5,000 bushels of corn that day. He still has his crop. The futures agreement is recorded in a separate trading account. What does the delivery month mean? Because this is a contract involving real corn, it has rules for completing a grain delivery. If a seller keeps the contract into that process, the seller must be prepared to meet the exchange's delivery requirements. A buyer who keeps the contract can be required to pay for and accept delivery under those same rules. This is a formal process using approved grain facilities and documents giving the buyer rights to the grain. It isn't simply Sam choosing any elevator and dropping off a truckload. But Sam wants to sell his harvested corn to his usual local elevator. He uses futures to protect against a falling price. He doesn't want to deliver through the exchange. The rules give him a way to end his futures obligation before the delivery process begins. And here's how exactly that works. Sam originally sold one December corn contract. To end that trade, he buys one December corn contract for the same year, covering the same 5,000 bushels in the same trading account. The contracts must match. Buying a week contract or a contract for another month would not end this corn agreement. Why does buying a matching contract work? Because the trading system matches his agreement to sell with an equal agreement to buy. Under the exchange's rules, those opposite agreements cancel his remaining delivery obligation. He no longer has to supply corn through that contract, and he doesn't have to receive corn through it either. But any money he gained or lost while that price changed still counts, that does not disappear. He doesn't have to find the original buyer and ask permission. His broker, the firm handling his trades, arranges the matching purchase through the market. Suppose Sam harvests and sells his real corn in October. He can make that matching futures purchase in October, well before the December delivery process. He doesn't have to wait until December. There are specific deadlines, including deadlines before the delivery month starts. His broker tells him when his trade must be ended to avoid delivery. That's what closing the trade before delivery means. Making the matching purchase in time to remove the obligation to deliver grain. It does not mean ignoring the contract or walking away from money owed. Why the local corn prices can be different. Before we put dollars to this, there's one more piece. The futures price is a common reference price. Sam's local elevator may offer a different amount for his actual corn. An elevator is a business that buys, stores, and handles grain. Its offer depends on things such as local supplies, nearby buyers, and the cost of moving the corn. Suppose futures are $5, but the elevator offers Sam $4.70. That local offer is 30 cents below futures. The difference is called basis. People would describe that as 30 cents under. Basis can change, and some buyers offer more than the futures price. For our example, we'll keep the elevator's offer 30 cents below futures the whole time. That lets us follow the money without changing everything at once. So what happens if corn prices fall? Remember, Sam sold his futures contract at $5. Now it's October. He has harvested his corn, and that same December futures contract is trading at $4. His local elevator offers $3.70. Sam sells 5,000 bushels of actual corn to the elevator for $370 a bushel. At about the same time, he buys the matching futures contract at $4 to end his futures trade. He sold the contract at $5 and bought it back at $4. That leaves him with a futures gain of $1 for each of the $5,000 bushels covered. That's $5,000 gained in his trading account before trading costs. Meanwhile, the elevator pays him $370 a bushel for the grain. Put those together, $370 from the corn plus $1 from the futures. His combined result is $470 a bushel before fees and other costs. The elevator still paid only $370. The extra dollar came from his separate futures trade. That is how futures help protect him when corn prices fell. What happens if prices rise instead? Let's go back and imagine a different October. This time, December futures rise to $6 with the same 30 cent difference. The elevator offers $5.70. Sam gets $5.70 a bushel for his actual corn, but he originally sold his future contract at $5. Now he must buy the matching contract at $6 to end that trade. That creates a $1 loss per bushel in his trading account. $570 from selling the corn minus $1 futures loss leaves $470 before costs. Sam received more for the grain but lost money on the futures. In the earlier example, he received less for the grain but gained money on the futures. Using futures this way is called hedging. Sam is using one transaction to help balance the price risk in another. He gains some predictability but gives up the benefit of rising futures prices on those bushels. And remember, we held that 30 cent local difference steady. In real life, it can change, so his final result can change too. But here's why Sam still needs money available. The money in the futures account is adjusted daily as prices move. Sam must keep a deposit there to help cover losses. That deposit is called a margin. If his trade loses money, the broker may require him to add more. That request is called a margin call. In our rising price example, Sam's corn became more valuable, but he was losing money on the futures. He may have to pay those futures losses before the crop is harvested and sold. So even a hedge that protects his overall selling price can create a need for cash along the way. The original deposit is not the most he can lose, and futures don't protect him from everything. If his crop fails, his futures obligations still exist. If his production costs are too high, a protected selling price may still leave him losing money. And that's why Sam has to consider his crop, his cost, and his available cash together.
