An option on futures references a specified futures contract or other exchange-defined futures exposure. Its exercise and settlement rules come from that option's contract specifications.
Exercise and settlement
For an option that delivers one futures position, exercising a call creates a long future for the holder and a short future for the assigned seller. Exercising a put creates a short future for the holder and a long future for the assigned seller. Some options instead settle in cash. Do not assume that exercising delivers the physical commodity directly.
Expiration dates and exercise style
Futures options may be American-style or European-style. Expiration can be monthly, weekly or another schedule; it is not universally the Friday before a delivery month. Check the exact option series, last trading time, exercise cutoff, underlying futures month and settlement method.
Premiums, margin and price risk
Premium quotations, multipliers and margining conventions differ across contracts. A resulting futures position carries variation-margin and potential delivery obligations. Losses can exceed the margin deposit. Some futures can trade below zero, so stock-option payoff assumptions based on a zero price floor are not universal futures risk limits.
Our stock/ETF expiration calculators do not model futures margin, settlement or negative underlying prices. Read the futures margin guide and the relevant exchange specifications.
