Starting from 2025-05-17 00:00 (UTC), Binance Portfolio Margin will introduce a tiered negative balance threshold for different assets based on users’ VIP levels. If a user’s negative balance in the Portfolio Margin Account exceeds the negative balance threshold, the user will be charged an interest fee based on the negative balance in the Portfolio Margin Account at 00:00 (UTC) daily. The interest fee is calculated based on Binance Margin Borrow Daily Interest Rate.
The interest fee calculation formula is as follows:
Interest Fee = abs(NegativeBalance) * dailyInterestRateNote: NegativeBalance = min(totalAssetBalanceAcrossPMAccounts + negative_threshold, 0)
Example 1:
User A is a VIP 9 user with a negative balance of 10,050 in USDT assets in their Portfolio Margin Accounts.
Based on the tiered negative balance thresholds, VIP 9 users can hold up 10,000 negative balance threshold for their USDT assets. Assume that the Binance Margin borrow daily interest rate for USDT assets is 0.1%, the interest fee charged will be calculated as follows:
Interest Fee = abs(-50*) * 0.1% = 0.05 USDT*NegativeBalance = min(-10,050 + 10,000, 0) = -50
Example 2:
User B is a VIP 9 user with a negative balance of 10,050 in USDT assets in their Portfolio Margin Account at 20:00 (UTC). User B then deposits 2,000 USDT assets to their Portfolio Margin Account and the negative balance becomes 8,050 USDT at 00:00 (UTC).
Based on the tiered negative balance thresholds, VIP 9 users can hold up 10,000 negative balance threshold for USDT assets and the interest fee is calculated based on the negative balance at 00:00 (UTC) daily. Thus, no interest fee will be charged to User B.
