According to CoinMeta, Binance has announced that it will update the settlement price rules for commodity options to align them with the calculation methods of crypto options. The new rules will take effect at the end of the US trading session on November 23, 2026, and will apply to all commodity options that expire after that time. The new rules stipulate that the settlement price will be the arithmetic average of the Binance Futures Index price within 0.5 hours before expiration. The affected contracts will determine whether to use the new rules or the old rules based on their expiration time.
