Bitget said it will revise position tiers, maximum leverage and maintenance margin rates for TENCENTUSDT, POPMARTUSDT, PANWUSDT, NBISUSDT, EWYUSDT, EWJUSDT, CATUSDT, BRKBUSDT and ASTSUSDT perpetual futures at 12:00 UTC on Aug. 13, 2026. New positions in those contracts will use the updated standards immediately, while existing positions will switch to the new framework at the effective time. The exchange warned that the changes may push some positions' maintenance margin rates above 100%, increasing liquidation risk unless users top up margin or reduce positions in advance. Bitget also said trading bots with positions or leverage above the revised limits may be terminated.
