# SunX to Update Funding Rate Calculation Formula for USDT-M Futures Dear SunX Users, To enhance your trading experience, SunX will adopt a new formula to calculate funding rates in USDT-margined futures trading, starting on **Jan 30 at 06:00 (UTC), 2026**. See adjustment details below: **Before Update** Funding rate = clamp \[Average premium index + clamp (Comprehensive interest rate - Average premium index, Premium deviation cap, Premium deviation floor), Funding rate cap, Funding rate floor] **After Update** Funding rate = clamp {\[Average premium index + clamp (0.01% - Average premium index, Premium deviation cap, Premium deviation floor)] / (8/N), Funding rate cap, Funding rate floor} Where: * N is the funding interval, taking a positive integer from 1 to 8. For example, if a certain cryptocurrency has a funding interval of 4 hours, then N will be 4. * The funding interval is dynamically adjusted and will take effect immediately after the adjustment. For instance, if the current time is 12:30 and the funding interval for a certain cryptocurrency is adjusted from 8 hours to 1 hour, the next funding settlement time will immediately change from 16:00 to 13:00. Thank you for your continued support and trust in SunX. SunX Team Jan 28, 2026 Find us on Twitter: Telegram: Linktreeļ¼š\
