BitMEX to Cut Minimum Price Increments on SOL, ADA, BCH and SEI Perpetuals
BitMEX announced that on 23 Jun 2026 04:00 UTC it will reduce the Minimum Price Increments (tick size) for several perpetual swap contracts. The Minimum Price Increments for SOLUSDT will fall from 0.01 to 0.001; ADAUSDT from 0.0001 to 0.00001; and BCHUSDT/BCHUSD from 0.05 to 0.01. SEIUSDT will also be reduced from 0.0001 to 0.00001. BitMEX notes that smaller Minimum Price Increments can help narrow bid-offer spreads for price takers. This is scheduled as a product update (listing/contract change notice), with traders able to contact Support for questions.

This is a venue microstructure change, not a protocol or macro catalyst. Cutting tick size (Minimum Price Increments) usually makes order book steps smaller, which can slightly improve liquidity presentation and reduce bid-offer spreads for takers. However, it does not directly change underlying fundamentals or margin/position leverage mechanics, so the overall market impact is typically limited.
In the short term, traders may react by adjusting limit-order placement and execution expectations around 23 Jun 2026 04:00 UTC, especially for SOL/ADA/BCH/SEI perpetuals where tick size becomes finer. This can increase quoting activity and reduce effective spread costs, but it is unlikely to create sustained directional moves by itself.
In the long term, if tighter tick sizing consistently improves depth and execution quality, it can marginally enhance trading efficiency and attract higher-frequency liquidity on BitMEX. Still, since spreads and liquidity are also driven by broader market volatility and participation, the expected impact remains neutral overall.
