Why Pig Prices Can Swing So Sharply
Pig production runs on a biological timetable, while prices move day by day. A farmer deciding whether to breed more pigs today is betting on what buyers will pay months from now, when those animals are ready for market. The delay makes supply slow to respond—and makes today’s price a poor guide to tomorrow’s.
How High Prices Can Set Up a Slump
When prices rise, many farmers may read the signal the same way: raising more pigs looks profitable. But breeding decisions cannot be quickly reversed, and the extra animals keep growing. By the time they reach market, other farmers’ herds may arrive at the same time, too.
That synchronized increase adds pork to the market all at once. If the amount available grows faster than demand, buyers have less reason to bid aggressively, and prices can drop. Farmers who expanded in response to high prices may then sell their larger batches into a weaker market.
The Farmer Is Betting on a Moving Target
This is a form of a production lag: the time between deciding to make more of something and having it available to sell. It creates a difficult tradeoff. Expanding can capture a future upswing, but it also risks adding supply after the upswing has passed; holding back can avoid a glut, but leave a farmer with fewer animals if strong prices persist.
So the market’s invisible price is really a forecast each farmer must make about what everyone else will produce, and when. The consequence is that a seemingly profitable decision, repeated across many farms, can help bring about the lower prices that make it unprofitable.
