Binance is introducing tiered negative balance thresholds for its Portfolio Margin accounts, starting May 17, 2025. This change affects how interest fees are calculated for users with negative balances. The new system will categorize users based on their VIP level and implement different thresholds for various assets. A daily interest fee will be charged at 00:00 (UTC) if the user’s negative balance exceeds the threshold. The calculation is based on the Binance Margin Borrow Daily Interest Rate and uses the formula: `Interest Fee = abs(NegativeBalance) * dailyInterestRate` . For example, a VIP 9 user with a negative balance of 10,050 USDT might face a fee of only 0.05 USDT if the daily interest rate for USDT is 0.1%. The threshold calculation follows: `NegativeBalance = min(totalAssetBalanceAcrossPMAccounts + negative_threshold, 0)`. Users with a negative balance need to ensure their Unified Maintenance Margin Ratio (uniMMR) exceeds the liquidation threshold of 105% to allow for these balances. 24-hour notice should be given before any potential interest accrual on Cross Margin Account for Auto Repay users.
