Bitget said it will revise leverage limits, position tiers and maintenance margin rates for eight perpetual futures pairs at 10:00 UTC on June 18, 2026. The changes cover TRUSTUSDT, THEUSDT, SANTOSUSDT, RESOLVUSDT, ORDIUSDT, ORDIUSDC, MAVUSDT and DIAUSDT. New positions will use the updated tier standards immediately, while existing positions opened before the adjustment will shift to the new standards at 10:00 UTC on June 21. Bitget warned that the changes may raise maintenance margin requirements, potentially pushing displayed maintenance margin rates above 100%, and said users should add margin or reduce positions to avoid liquidation. The exchange also said trading bots with positions or leverage above the revised limits may be terminated if they are not adjusted in advance.
