Futures Options: Rights, Obligations, and Exercise Outcomes
What you own after exercise
An option on a futures contract gives the buyer the right, but not the obligation, to establish a long (call) or short (put) futures position at the strike price. Exercise does not deliver the cash commodity; it creates a futures position that carries its own margin requirement. Buyers pay the premium in full and can lose only that premium. Writers (grantors) collect the premium, post margin, and accept assignment risk; a naked call writer faces theoretically unlimited risk.
Core vocabulary: strike price, premium, intrinsic value, time value, in/out/at the money, American versus European exercise, expiration, assignment, and delta. Most futures options in the U.S. are American style, exercisable any business day before expiration, and assignment is allocated through the clearinghouse, so a writer can be assigned early.
Traps that appear in questions
- Confusing premium with margin. The buyer pays the premium in full; it is not a performance bond.
- Forgetting that exercise produces a futures position with a new margin obligation, not a delivered commodity.
- Assuming an in-the-money short option simply disappears at expiration: it is typically exercised automatically unless the holder instructs otherwise.
- Mixing up offset (closing the option) with exercise; most options are offset rather than exercised.
Worked example
Buy a call at a premium of 3.50 points, strike 450, contract multiplier $250. Premium paid = 3.50 x $250 = $875. At expiration the futures settle at 460, so intrinsic value is 10 points = $2,500. Net profit = $2,500 minus $875 = $1,625. Breakeven at expiration = strike plus premium = 453.50.
