Binance Shifts Commodity Options to 30-Minute Settlement

By Tom Whitfield

Binance will settle commodity options using a 30-minute average of the Binance Futures Index Price, beginning with contracts expiring at 5 p.m. ET on Nov. 23. The exchange will use the same calculation for later expirations, aligning commodity options with the settlement method already used for Binance crypto options.

What changes on Nov. 23?

The first affected contracts will replace one reference point—the underlying market's closing price at 5 p.m. ET on the expiration date—with an average taken immediately before expiration. For contracts expiring at 5 p.m. ET on Nov. 23, the measurement window runs from 4:30 p.m. to 5 p.m. ET.

Binance's announcement describes the settlement price as the "arithmetic mean" of the Binance Futures Index Price during the half-hour before expiration. That calculation aggregates index-price values across the defined window rather than fixing the benchmark to one closing level. The resulting single figure becomes the contract's settlement price under the revised rule.

The methodology change does not alter the surrounding contract schedule. Binance is keeping expiration times, trading sessions and contract specifications unchanged. Participants therefore face a new calculation for the final settlement figure, not a new expiration time, trading session or set of contract terms.

How do the old and new methods differ?

The existing method anchors settlement to the underlying market's closing price at 5 p.m. ET on the expiration date. The revised method uses a 30-minute period before expiry and the Binance Futures Index Price as its reference series.

That changes how the benchmark responds to price movements around expiry. Under the old approach, the closing level carries the full weight of the reference. Under the new approach, the arithmetic mean distributes that weight across the half-hour window, so the settlement figure is less dependent on any single index-price reading.

The distinction is mechanical rather than a change in the underlying commodity contracts. Binance is not changing the moment at which the affected contracts expire or the sessions in which they trade. It is changing the price used to complete settlement once the existing expiration schedule reaches the applicable expiry.

Why does the change matter?

Binance has put both commodity options and crypto options on the same averaging framework. That reduces a methodological difference between the two categories, while the exchange's retention of existing times, sessions and specifications keeps the change limited to settlement.

For traders and market makers, the operational implication is confined to the expiry calculation. A commodity-options contract expiring under the new rule will settle from the average futures-index level over its pre-expiry half-hour, rather than from the underlying market's 5 p.m. ET close on the expiration date.

The final reference can therefore differ from the prior method even though the contract's listed schedule has not changed. No broader changes to trading hours or contract design are part of the announcement. The exchange has identified one variable—the settlement-price calculation—and left the other stated operating terms intact.

The announcement identifies a single changed variable: the expiration benchmark. It does not revise the stated contract specifications.

When does the new method take effect?

The Nov. 23 expiry is the first scheduled event under the revised method. Contracts expiring at 5 p.m. ET that day fall within the new 30-minute window, and Binance says later expirations will use the same formula.

Expiration time determines which method applies, while Binance keeps expiration times, trading sessions and contract specifications unchanged. For settlement desks and traders, the practical focus is therefore the final half-hour before each applicable expiry. The implementation deadline is the Nov. 23 expiry at 5 p.m. ET, after which each subsequent expiration follows the same futures-index averaging calculation.
