The Core Playbook
Most farm hedges with corn options come down to a short list. The protective put is the simplest: buy a put, pay the premium, and hold a floor under your unpriced bushels. The fence adds a sold call above the market to bring in premium and lower the net cost, but it caps your gain and can create margin requirements on the short call.
- Protective put sets a floor, keeps all upside, costs the most.
- Fence (collar) cuts the cost, caps the upside, may require margin.
- Combinations with different strikes or months can tailor the floor to your cash flow and storage plans.
There are fancier structures, but most of them are these two ideas with the strikes moved around. If someone pitches you something you cannot diagram on one line, ask what problem it solves that a put or a fence does not.
Matching the Strategy to Your Situation
Start with the question you are actually trying to answer. If you have sold nothing and cannot afford a price break, a put gives you a floor with no delivery obligation. If premium expense is the obstacle, a fence lowers the out-of-pocket cost but obligates you at the call strike if corn rallies hard. Your basis, storage costs, and the share of the crop already priced all shape which structure fits.
Each corn contract covers 5,000 bushels, so the number of puts should roughly track your unprotected bushels, not your whole bin.
Timing is part of the choice as well. Puts bought in late winter, before weather risk enters the market, usually carry lower implied volatility and more time value than puts bought in July with a drought underway. The trade-off is paying for more time. A broker who works with farm hedgers can walk through current premiums and help you compare structures on equal footing.
Where Option Hedges Go Wrong
The most common mistakes are buying protection too late, after volatility has already driven premiums up, and treating a sold call as free money when it carries real margin risk. Another is over-hedging: buying puts on more bushels than you can reasonably produce turns insurance into speculation.
Futures and options trading involves substantial risk of loss and is not suitable for all investors. No strategy guarantees a profitable result, and a broker can help you size a hedge honestly against your expected production.
