Important: Update to the Isolated Margin Calculation Formula

To provide a better futures trading experience, we will upgrade the margin calculation formula under isolated margin mode from 03:00 to 04:00 (UTC) on May 22, 2025.

This upgrade will adjust the formulas for maintenance margin and liquidation fees to make liquidation assessments more aligned with real-time risk. It will also reduce the capital freeze pressure when opening positions, further improving capital efficiency and risk control in futures trading. During the upgrade, futures trading and related features will not be affected. After the upgrade, all isolated margin positions will be assessed and calculated using the new formula.

Details are as follows:

I. Upgrade Time
Upgrade Time: May 22, 2025, 03:00–04:00 (UTC)
Estimated Completion Time: May 22, 2025, 04:00 (UTC)

II. Upgrade Details
We will adjust the margin calculation formula for isolated margin mode
Before Adjustment:
Margin Rate = Maintenance Margin / Total Position Margin
Maintenance Margin = Position Maintenance Margin + Bankruptcy Fee + Estimated Funding Fee = Average Entry Price × Position Size × Contract Multiplier × (Maintenance Margin Rate + (1 + 1/Leverage) × Taker Fee Rate + Funding Rate)
Total Position Margin = Initial Margin + Additional Margin + Funding Fee + Bankruptcy Fee + Unrealized PNL

After Adjustment:
Bankruptcy Fee Freeze Removed: Bankruptcy fees will no longer be frozen when opening a position.
Introduction of Liquidation Fee:
Liquidation Fee = Mark Price × Position Size × Contract Multiplier × Liquidation Fee Rate
Liquidation fee will be calculated in real time and only charged when liquidation occurs.
Maintenance Margin Optimization:
Entry Price is replaced with Mark Price for maintenance margin calculation.
Optimized Margin Rate = Maintenance Margin / Total Position Margin
Where: Maintenance Margin = Position Maintenance Margin + Liquidation Fee + Estimated Funding Fee = Mark Price × Position Size × Contract Multiplier × (Maintenance Margin Rate + Liquidation Fee Rate + Funding Rate)
Total Position Margin = Initial Margin + Additional Margin + Funding Fee + Unrealized PNL

Important: Adjustment to Perpetual Contract Funding Fee Settlement Times and Payment Rules

To provide a more professional trading service and enhance your trading experience, KuCoin will be updating the funding fee payment rules for perpetual contracts in phases. Funding fees will switch from a cross-period payment model to a current-period payment model. The settlement times will also be adjusted. Below are the details of these changes:

1. Funding Fee Settlement Time
Before the Update: For an 8-hour cycle, funding fee settlement times (UTC) were 04:00, 12:00, and 20:00.
After the Update: For an 8-hour cycle, funding fee settlement times (UTC) will be 00:00, 08:00, and 16:00.
2. Funding Fee Payment Rules
Before the Update: Funding fees were calculated based on the funding rate from the previous settlement time—this is known as cross-period payment. Example: For an 8-hour cycle, at 20:00 each day, the system would calculate the funding fee using the rate derived from the premium index between 04:00 and 12:00. As a result, the funding rate for the period between 12:00 and 20:00 would remain fixed.
After the Update: Funding fees will now be calculated using the funding rate at the current settlement time—this is known as current-period payment. Please note that the settlement time of funding fees has been changed. #Example: At 16:00 each day, the system will calculate the funding fee using the funding rate based on the premium index between 08:00 and 16:00, and the fee will be settled at 16:00. Please note that the funding rate may fluctuate up until settlement time, so you can manage your positions accordingly.
Special Notice: According to the update schedule below, all contracts will be charged the funding fee for the previous cycle at 04:00 (UTC) on the update date, and charged again for the current cycle 4 hours later at 08:00 (UTC).

After this update, funding fees will be settled based on the new timing and cycle rules. Please pay close attention to your contract positions.

KuCoin’s Supplemental Notice on the Optimization of the Isolated Margin Calculation Formula

KuCoin recently announced updates to the isolated margin calculation formula, along with adjustments to the funding fee settlement time and payment rules for perpetual contracts.

Please note that after the adjustments to funding fee, the isolated margin formula will no longer include funding fees in the maintenance margin calculation.The expected funding fee will be zero. Please review your contract positions carefully, as they will be impacted by the following adjustments:

Adjusted Margin Rate = Maintenance Margin / Total Position Margin
Where: Maintenance Margin = Position Maintenance Margin + Liquidation Fee + Estimated Funding Fee = Mark Price × Position Size × Contract Multiplier × (Maintenance Margin Rate + Liquidation Fee Rate + Funding Rate)
Total Position Margin = Initial Margin + Additional Margin + Funding Fee + Unrealized PNL

Note: Prior to the adjustment, contract funding fees still include the aforementioned fees. Please refer to the announcement below for the adjustment schedule.
