Gate will upgrade the funding rate algorithm for perpetual contracts on May 27, optimizing the calculation method of the premium index

Gate News, according to a Gate official announcement on May 27, 2026,

Gate will upgrade and optimize the perpetual contract funding fee rate algorithm on May 27, 2026 at 16:00 (UTC+8). This optimization mainly involves two changes: updating the calculation method of the average premium index from an arithmetic average algorithm to a time-weighted average algorithm, and upgrading the funding fee rate calculation formula to support more flexible settlement cycles.

Under the new algorithm, the funding fee rate formula changes from the previous arithmetic average method based on a daily 0.03% default interest to a calculation method that combines a 0.01% base interest rate with the time-weighted average premium index. At the same time, it introduces the funding fee rate settlement frequency (N) as a variable, making the formula more flexible. Taking the BTCUSDT contract settled every 8 hours as an example, the new formula directly calculates the difference between the average premium index and the base interest rate, while the funding fee rate upper and lower bounds remain at -0.3000% to +0.3000%.
