What You Own After a COMEX Gold Option Is Exercised

Identify the contract behind the strike

COMEX Rulebook Chapter 115 defines its standard Gold Option in terms of an underlying Gold futures position. The contract month printed on the option maps to a futures month under the published schedule. For example, the January and February monthly options both map to the February future. Looking up the front-month spot gold chart would give you a different reference.

The standard monthly option is American style, allowing exercise before expiry on eligible business days. Exercising a long call creates a long futures position at the strike. Assignment gives its writer the opposite futures position. A long put exercised into futures produces a short futures position and its assigned writer takes the long side. Specify the product when using these rules because other gold-linked options can have different terms.

Separate intrinsic value from the premium paid

Take a hypothetical standard call with a $3,000 strike, bought for $15 per ounce. Use a 100-troy-ounce underlying futures contract. If the relevant futures reference at expiry is $3,008, the call has $8 per ounce of intrinsic value, or $800. The premium paid was $1,500. Measured at that reference, the option’s intrinsic value less the original premium is negative $700 before commissions or other costs.

The same calculation gives a $3,015 premium break-even at expiry before costs. That is a different threshold from the $3,000 strike that determines whether the call has intrinsic value. A reader who uses the higher number as the exercise cutoff can misunderstand why the account received an assignment or a futures position. The example assumes hypothetical prices and does not describe an actual expiry.

Account for the position on the next line

Suppose the buyer now carries the resulting long future. A subsequent $2-per-ounce decline in that future changes the position value by another $200 for one standard contract. The option premium has already been accounted for. Charging it again in the futures ledger would overstate the loss, while ignoring the futures position would hide continuing exposure. An open future can also introduce margin obligations.

If the intent was to limit exposure to the period before expiry, the useful question is what the broker’s confirmed position shows after processing. An option disappearing from the open-options list does not establish that the whole account is flat. Record the futures month, direction and quantity alongside the option’s final status.

Make the calendar specific to the ticket

I would place the exchange expiration, the broker’s instruction deadline and the time assignment reports become available on three separate lines. Chapter 115 gives the monthly expiration rule and exceptions for certain weekdays and holidays. The broker’s earlier customer cutoff, where applicable, needs its own confirmation. Before carrying risk overnight, reconcile the resulting position and the funds required for it against the clearing or broker statement.
