Binance announced it adjusted the tick size for selected USDⓈ-M perpetual futures contracts, including AVNTUSDT and SUIUSDC, at 07:00 UTC on September 19, 2025. The aim is to enhance market liquidity and improve the trading experience.
According to Binance’s official press release, the adjustment of tick sizes is part of an initiative to refine the trading environment and provide a smoother experience for futures traders. Tick size defines the minimum increment at which a contract price can move and directly impacts liquidity, price discovery, and execution efficiency. Binance emphasized that these adjustments will not disrupt ongoing trading activity, as existing orders will continue to be matched based on their original tick size settings.
The specific changes apply to two perpetual contracts: AVNTUSDT and SUIUSDC, which will both see their tick size adjusted from 0.00001 to 0.0001. By broadening the minimum unit price change, Binance aims to reduce market fragmentation caused by excessively granular pricing. API users will also see these modifications reflected automatically in the GET /fapi/v1/exchangeInfo endpoint, ensuring uniformity across all trading platforms and integrations.
