According to the official announcement, Binance will implement a tiered negative balance threshold mechanism for portfolio margin accounts starting at 0:00 (UTC) on May 17, 2025. The higher the VIP level, the higher the negative balance threshold that can be held. If the negative balance of the account exceeds the corresponding threshold, the system will charge interest fees at 0:00 (UTC) every day according to the margin lending daily interest rate. Negative balances are only allowed when the unified maintenance margin rate (uniMMR) is higher than the 105% liquidation line, and interest will affect the uniMMR value.
