On 31 August 2026 at 08:30 UTC, BitMEX set two contracts, XAUTUSDT and SUIUSDT, to Reduce Only mode. When Reduce Only mode is set, traders are no longer able to increase the size of their positions, open positions can only be reduced and no new positions cannot be opened. There is an exception that allows designated market makers to increase their positions so they can continue to provide liquidity.
