Optimization of UTA Loan interest rules

To further enhance transparency and fairness, we’re updating the interest calculation rules for UTA Loan.

This update takes effect on Mar 23, 2026, 10AM UTC. Please review the new rules and plan your borrowing and trading accordingly.

What’s changing: Spot liabilities interest calculation

From the effective time, interest on spot-related borrowings will follow the rules below.

First interest calculation

Interest starts immediately after you borrow assets.

The first interest period runs from the borrowing time to the next fixed calculation time, which occurs 5 minutes past each hour.

For interest calculation purposes, any period shorter than 1 minute is counted as 1 minute.

Formula:

First interest = Borrowed amount × hourly rate × (actual minutes ÷ 60)

Example:

If the fixed calculation time is 5 minutes past each hour and you borrow at 14:38:

First interest period: 14:38 – 15:05

Duration: 27 minutes

First interest = Borrowed amount × hourly rate × (27 ÷ 60)

Hourly interest after the first interest period

After the first interest period ends, interest accrues once every hour at each fixed calculation time.

Interest continues to accrue until you fully repay the loan or it reaches maturity.

Using the example above:

After 15:05, the next interest calculation occurs at 16:05, based on a full hour from 15:06 to 16:05.

Scope

Spot liabilities refer to loans generated from:

• Spot margin trading

• Manual borrowing with flexible interest rates

From Mar 23, 2026, 10AM UTC, interest generated on these liabilities will follow the new rules.

This update does not affect derivatives liabilities. They will continue to accrue interest once per hour under the existing mechanism.

Thank you for your continued support.
