What it means
A futures contract is an agreement to buy or sell a set quantity of something at a fixed price on a future date. The pork belly contract covered frozen bellies in a standard lot size, and traders used it to lock in prices or to bet on price moves.
Producers, bacon makers and speculators all took part. The contract served a business purpose.
A meat processor worried about rising costs could buy futures to fix its purchase price, while a producer worried about falling prices could sell futures to protect revenue. This is called hedging, which means using a market position to offset a business risk.
Speculators were the other side of the market. They did not want the meat, so they closed their positions before delivery, hoping to profit from price moves.
Because futures are traded with margin (a small deposit that controls a much larger position), small price changes could produce large gains or losses. Prices swung with seasonal demand, cold storage stocks, supply and the weather.
Pork bellies earned a reputation for volatility, and the contract appears often in books and films about trading. The contract was eventually delisted by its exchange, so it is now mostly a historical example, though the same principles apply to other commodity futures.
The lessons remain useful for finance teams. Hedging reduces uncertainty but does not remove it, since basis risk (the gap between the futures price and the price of the actual goods) can leave a business slightly exposed.
Margin calls (demands for more deposit when prices move against a position) can also create sudden cash needs. Understanding this type of contract helps non-specialists read news about commodity markets.
It also shows how a processor's costs can be linked to what happens on a trading screen.
In practice
Real-world examples.
Example
A bacon manufacturer expects to need a large quantity of bellies in three months. It buys futures at a price it finds acceptable, which fixes much of its cost whatever happens in the market. If prices rise, the gain on the futures offsets the higher cost of the meat.
Example
A trader believes cold storage stocks are lower than the market expects and buys a contract. When stocks are reported to be low, the price rises and the trader sells for a gain. The trader never sees or handles any meat.
Example
A food company's finance team reviews its hedging policy. It uses an example of an old pork belly hedge to show how basis risk can leave a gap between the futures result and the cost of the meat actually purchased. The team adds a margin reserve to its hedging policy.
Formula
Calculation
Profit or loss on a futures position = (selling price - buying price) x contract size
Suppose a standard contract covered 40,000 pounds of pork bellies. A trader buys one contract at $0.80 a pound and later sells it at $0.85 a pound.
Profit = (0.85 - 0.80) x 40,000 = 0.05 x 40,000 = $2,000.
If the price had instead fallen to $0.75, the loss would be (0.75 - 0.80) x 40,000 = -0.05 x 40,000 = -$2,000.
The contract's value at $0.80 a pound was 0.80 x 40,000 = $32,000, so a margin deposit of a few thousand dollars controlled a $32,000 position.Case study
Seen in the real world.
Redwood Smokehouse is a fictional bacon maker that needs 400,000 pounds of bellies in a year. Its finance director worries that prices could rise before the purchases. In this illustrative case, she buys ten futures contracts of 40,000 pounds each at $0.80 a pound.
By the time of purchase, the market price has risen to $0.90, so the company pays $0.10 more per pound on the meat. However, the futures contracts have also gained $0.10 a pound, which is 0.10 x 400,000 = $40,000 of profit. The hedge offsets the extra cost.
The company's cost is therefore close to the $0.80 it planned for, apart from small differences between the futures and its actual purchase price. The experience persuades the board to keep a formal hedging policy, with written limits on how much of the expected purchases may be hedged and who may approve each trade.
Watch out
Common mistakes.
- Believing that the buyer must take delivery of the meat. Most traders close their positions before delivery.
- Ignoring margin. A small adverse move can trigger a call for extra funds, and a business that cannot find the cash quickly may be forced to close its position at a loss.
- Assuming a hedge removes all risk. Basis risk and timing differences can leave a gap between the hedge result and the actual cost of the goods.
