Dear OKX Users,

Details of the adjustment are as follows:
Please note that due to market conditions, the adjustment time for certain tokens may change or be postponed. Please refer to the *Position Tier Description* to confirm whether the adjustments for relevant tokens have been successfully implemented.
**Risk Reminder**
Due to recent significant market fluctuations, the maintenance margin rate for user positions may increase after the tiered margin rule adjustment. To prevent forced liquidation caused by the rule changes, 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 better products and higher-quality services!
