Bitget announced two separate derivatives changes for September 2026. On Sept. 20 at 13:00 UTC, it plans to change GUSDT perpetual futures funding calculations from every four hours to every hour, with published limits of +2.0000% and -2.0000%. On Sept. 22 at 04:00 UTC+0, it plans to revise USDT leverage limits, position-size tiers and maintenance margin rates in its UTA (unified trading account) system. Bitget warned that maintenance margin requirements for USDT-collateralized positions may rise, increasing liquidation risk, and advised users to review funding rates, close or reduce positions, or add margin. The exchange may reschedule the GUSDT change during high market volatility and reserves the right to modify, amend or retract its notices without prior notice.
