Margin Service Terms

By using the Margin Services, you acknowledge that you have read, understood, and accepted all of the terms and conditions in the Margin Service Terms, and you acknowledge and agree that you will be bound by and will comply with the Margin Service Terms. This Isolated Margin Trading Guide does not govern the Margin Services and is provided for your information and convenience only. In the event of any conflict between this Isolated Margin Trading Guide and the Margin Service Terms, the Margin Service Terms shall prevail.

Collateral

In the Isolated Margin mode, each trading pair has a specific Isolated Margin account. The net assets in each Isolated Margin account can only be used as a margin for the specific trading pair. Each Isolated Margin account can only accept the base asset and the quote asset in its specific trading pair as margin.

Assets Borrowing

In the Isolated Margin mode, users can only borrow the two specific digital assets in the relevant trading pair as loan assets. For more details, please refer to the Margin Data page.

Dynamic Interest Rate

Simple interest accrues on an hourly basis. Interest is calculated first at the time of the successful advance of the relevant Margin Loan, which will be counted as the first hour. It will be calculated again at the next full hour (which will be counted as the second hour), and then every following full hour until the Margin Loan is repaid. This means that even if the Margin Loan is outstanding for less than an hour, interest will be charged for one full hour.
Interest is calculated according to the following formula:
Interest = Principal Amount Outstanding * Hourly Interest * Number of Hours the Loan Has Been Outstanding
Example: Assume the hourly interest is 0.001%. User A borrows 1,000 USDC at 13:20 and repays at 14:15.
Interest Rate = 1,000 * 0.001% * 2 hours = 0.02 USDC
User A was charged for two hours because interest is charged once for the borrowing between 13:20 to 13:59 and another from 14:00 to 14:15.
You may repay debts at any time. Repayment shall be deemed payment of interest first, and after interest is fully paid, repayment of the principal of the relevant Margin Loan.
Outstanding loan interest shall be included in the calculation of the Margin Level. Assuming no payments of interest are made for an extended period, the Margin Level of the user's Isolated Margin account may deteriorate, leading to the risk of a margin call or even forced liquidation.
Margin account interest rates are adjusted occasionally to reflect market conditions. You can find the latest interest rate on the Margin Data page.

Margin Level and Risk Controls

Users may only use the net assets in their Isolated Margin account at Binance as the collateral for Margin Loans, and the digital assets in any other accounts are not included in the calculation of Margin for Isolated Margin trading. The table below illustrates the risk controls at different margin levels.

The Margin Level of an Isolated Margin Account is calculated as follows:
Margin = Total Asset Value of an Isolated Margin Account / (Total Liabilities + Outstanding Interest)
where:
Total Asset Value of an Isolated Margin Account = Current Total Market Value of All Digital Assets in the Isolated Margin Account
Total Liabilities = Current Total Market Value of All Outstanding Margin Loans in the Isolated Margin Account
Outstanding Interest = Principal Amount Outstanding * Number of Hours the Loan Has Been Outstanding * Hourly Interest Rate - Interest Paid
Please note that the Initial Risk Ratio, Margin Call Ratio, and Liquidation Ratio vary for different leverage levels. Please refer to Tiered Leverage Function on Isolated Margin for more details. Please note that you won’t be able to update your margin positions during the liquidation process.

Sub-accounts

Sub-accounts for Isolated Margin Accounts can only be enabled after opening a Cross Margin Account. The number of sub-accounts you can open is subject to your master account’s VIP level. You may refer to the ‘Frequently Asked Questions’ tab in this article to find out more.
The maximum loan limit of each sub-account is calculated by taking the highest tier loan limit of a trading pair divided by a denominator as shown in the table below:.
VIP Level0123456789
Denominator1248101010101010
However, the maximum loan limit of each sub-account for a VIP user with custom sub-account limit settings is calculated by taking the highest tier loan limit of a trading pair divided by the number of sub-accounts.
