Borrowing, Interest, and Repayment in Unified Accounts

Última atualização: 10/12/2025

In the multi-currency margin mode of Unified Trading Accounts, users can borrow assets to facilitate margin trading (coming soon) or futures trading. This article will guide you through the borrowing rules, interest calculation, and repayment steps within the Unified Account.

I. Borrowing Mechanism

Auto-Borrow

If your balance in a certain asset is insufficient during trading, the system will automatically borrow the required asset for you based on your available margin, resulting in borrowing liabilities.
Borrowing Limit
The borrowing limit is determined by your account’s net asset value, margin conversion rate, and risk level.

Borrowing limits vary by currency.
Use Cases
Margin trading (coming soon): If your balance is insufficient when using leverage in spot trading, the system will borrow the asset for you automatically.
Futures trading: Borrowing doesn’t occur when opening a position. However, if unrealized P&L causes a negative balance in a specific asset, the system will automatically borrow the required amount. KuCoin provides an interest-free borrowing limit, where no interest will be charged on borrowing due to unrealized P&L within that limit.

II. Interest Calculation

How Interest Is Calculated

Interest is charged every hour, based on the liability amount at the top of the hour.

For futures unrealized P&L-generated liability, if it falls within the interest-free limit, no interest will be charged.
Interest Rates
Rates vary by coin and will be adjusted dynamically based on market conditions.

For the latest rates, refer to the “Borrowing/Lending Rate Table” in classic margin trading. During the grayscale test period, the borrowing rate is set to the highest VIP level by default.
Interest Deduction
The system will first deduct interest from your available account balance.

If the balance is insufficient, interest will be added to your borrowing liabilities.

Example: Maintenance Margin Rate for Futures

Assume the USDT interest-free allowance is 2,000 USDT, and the hourly interest rate is 0.01%. User A currently has 10,000 USDT in unrealized PNL-generated liabilities.

Interest-Free Amount
In cross margin mode under the multi-currency margin account, any unrealized PNL from futures positions comes with an interest-free allowance. Liabilities generated from unrealized losses within this amount will not incur interest.

III. Repayment Rules

Automatic or Manual Repayment

When you deposit, transfer in, or buy a liability asset, repayment will be automatically triggered.
Forced Repayment

The system checks the borrowing limits every 5 minutes:
If your borrowing exceeds your personal limit, the excess will be automatically swapped and repaid.
If the platform’s total borrowing limit is surpassed, users with excessive borrowings will be selected for automatic repayment.
If account risk ratio is too high, forced liquidation may occur, and the system will automatically sell assets to repay the borrowed amount.

IV. Reminders

It is recommended to regularly monitor borrowing conditions and interest rate fluctuations to prevent excessive interest accumulation.
Proper use of the borrowing feature can enhance capital efficiency, but be mindful of the risks involved.
It is advisable to maintain adequate margin during volatile market conditions to prevent forced repayment.
