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

Adjustment to Perpetual Contract Funding Fee Settlement Times and Payment Rules

Dear KuCoin Users:

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.

Taking SOLUSDCM as an example, the funding fee settlement rules are as follows:

Funding Fee Payment Time(UTC)	Funding Rate Settlement Rules
2025.06.02 20:00	[Old] Based on premium from 06.02 04:00–12:00
2025.06.03 04:00	[Old] Based on premium from 06.02 12:00–20:00
2025.06.03 08:00	[New] Based on premium from 06.03 04:10–07:59
2025.06.03 16:00	[New] Based on premium from 06.03 08:00–15:59
Subsequent periods follow this pattern…

4. API Update

To help users better understand the funding fee settlement cycle and improve system integration, we will optimize the existing funding rate query API:
GET /api/v1/funding-rate/{symbol}/current

The following two fields have been added:
period（Current Cycle Marker）

Type: Integer（0 or 1）
Description: Indicates whether the current funding fee is charged in this cycle
- 1: indicates will be charged in the current cycle;
- 0：indicates it is a cross-period fee record,not charged in the current cycle.

fundingTime（Next Settlement Time）

Type: Timestamp (milliseconds)
Description: Indicates the next funding fee settlement time pointwhich can be used to synchronize periodic settlement timing.

API Compatibility Reminder:
This updated API is backward compatible. All existing fields remain unchanged, and the new fields will be returned uniformly. Please complete the parsing support as soon as possible.
