**[Announcement Regarding Adjustment of Leverage Tier Levels and Discount Rate Levels by OKX]** Dear OKX Users, To further enhance market liquidity and mitigate market risks, OKX plans to adjust certain leverage tier level rules on September 30, 2025, from 2:00 PM to 6:00 PM (UTC+8). **Specific adjustment details are as follows:** For isolated margin and single-currency margin modes, the cross-margin leverage will be adjusted according to the tier levels outlined in the table above. For multi-currency margin mode and portfolio margin mode, the cross-margin leverage will be adjusted based on the trading currency rules for USDT pairs as specified in the table above. For more details, please refer to: **Position Tier Level Explanation** **Discount Rate Levels for Currencies:** The discount rate levels for currencies will be synchronously adjusted based on the tier levels for USDT pairs outlined in the table above. The adjustment method is illustrated in the following example: Suppose the maximum borrowing amount for the first tier of ENJ/USDT trading currency is adjusted to 100,000 ENJ. Accordingly, the maximum collateral amount for the first tier of ENJ's discount rate level will also be adjusted to 100,000 ENJ. Calculations for other tiers will follow this principle. For more details, please refer to: **Currency Discount Rate Explanation** **Risk Warning** Due to recent significant market fluctuations, the maintenance margin rate for user positions may increase after the tier level rule adjustments. To prevent forced liquidation caused by these adjustments, please promptly manage your risk by closing positions, reducing positions, or adding margin to lower the actual leverage ratio. OKX will continue to provide you with superior products and high-quality services! **OKX Team** September 26, 2025
