Micro Gold Futures vs. Gold Futures: MGC vs. GC

CME COMEX's current rulebooks define GC as a 100-troy-ounce Gold futures contract and MGC as a 10-troy-ounce Micro Gold futures contract. The ratio is therefore one MGC contract unit to one tenth of a GC contract unit. That is a useful scale comparison, but it is not a claim that every feature of the two products is automatically one tenth or otherwise identical.

Begin with the exact products, exchange, and month-year. A chart label or a broker's abbreviated symbol can conceal the multiplier, quote convention, listing, and final-process terms that make one contract different from another.

How to read futures contract specifications provides the fields to compare before treating two gold products as a simple size ratio.

Because GC's contract unit is ten times MGC's current contract unit, the same dollars-per-troy-ounce movement has ten times the unit-based dollar effect for one GC contract before considering quantity, fees, and the applicable account or settlement process. That relationship comes from the multiplier, not from a prediction about the direction of gold or the risk of a position.

The minimum price increment and its dollar value should be verified from the current specification for each product. Futures tick value and contract multipliers separates quote movement, multiplier, tick, and number of contracts so a reader does not turn a displayed price into the wrong cash scale.

If a position has more than one contract, calculate the product's multiplier and tick value for each contract first, then multiply by the contract count. Do not call one MGC contract “the same exposure” as one GC contract merely because both reference gold.

The word micro describes the contract unit. It does not guarantee a fixed margin ratio, cap the loss of an open futures position, establish the number of contracts an account may hold, or prove that a quote can be executed at a particular size. Current exchange, clearing, and broker requirements can change, and each account can have its own controls.

Futures margin versus leverage explains why a performance bond is not the contract's price or a maximum-loss figure. Compare current margin, cash movement, and account policy as separate records from the unit ratio.

Both GC and MGC have physical-delivery terms under their current CME COMEX rules, but their delivery mechanisms should not be collapsed into a generic statement that each long receives a bar of the stated contract unit. CME's MGC rulebook describes a clearing-member delivery mechanism using an Accumulated Certificate of Exchange, or ACE, tied to a Gold Futures warrant. The rulebook alone does not establish what a customer account may receive or hold; current broker and account terms remain separate checks.

Product month and lifecycle dates matter before any delivery question. First notice day and last trading day explains why an operational date can matter before a generic idea of expiry. Read each product's current calendar, delivery conditions, clearing procedure, and broker deadline rather than moving a conclusion from GC to MGC or the other way around.

Make one complete record for MGC and another for GC. Include product code, exchange, month-year, troy-ounce multiplier, quote unit, minimum price increment, tick value, contract count, notice and trading dates, final process, price field, timestamp, source, and account controls. Then the scale difference is explicit without turning it into a recommendation.

For readers starting from the commodity itself rather than a product code, what commodity futures are sets out why a commodity name, delivery term, and futures contract are separate parts of one complete record.

This guide compares contract mechanics, not a recommendation to trade gold, hold a micro contract, take delivery, or infer a return. Current CME COMEX rules, clearing, market data, and account policies govern an actual position.
