Announcement from Ouyi on the Consolidation of Rate Currency Pair Grouping Dear Ouyi users, in order to further simplify the fee structure and reduce transaction costs, we are about to group and merge the transaction pairs of spot and contract fees. Starting from 15:00-17:00 (UTC+8) on August 14, 2026: Trading pairs in spot group 2/group 3 and contract group 2 will be merged with their corresponding group 1, and the rate for group 1 of each product line will apply. This adjustment does not change the rules for determining your VIP level and transaction fee level. Before the product adjustment, the spot market after adjustment applies different rate related transactions according to the spot group 1/group 2/group 3. For the unified application of the original spot market group 1, the rate contract applies different rate related transactions according to the contract group 1/group 2. For the unified application of the original contract group 1, the rate denominated in French currency (such as TRY/BRL/AED/AUD/SGD) and the zero rate, stable currency and other groups maintain the existing rules, which are not within the scope of this adjustment. Please note that not all trading pairs are available in all jurisdictions, and the availability of trading pairs is subject to applicable laws and regulations, which vary by jurisdiction. Due to the fact that trading pairs are constantly being added, removed, and updated, this trading pair is for reference only. If you need to know the latest applicable rates for trading pairs, please refer to OpenAPI or the www.(okx.com)/feet page. 1、 After the adjustment of the spot rate table from 15:00 to 17:00 (UTC+8) on August 14, 2026, the following table shows the uniformly applicable rates for spot trading: the asset threshold is determined at the account level and consistent with the contract; The 30 day trading volume threshold is determined separately by product line.
