Deribit Tick Size Reductions for Nine Altcoin Perpetuals

Summary

The notice describes a scheduled reduction in minimum price increments for nine linear USDC perpetual contracts. It lists each contract’s old and new tick size and says the update applies to both displayed order books and block trades. The stated goal is to improve tradability and support more trading activity.

From the effective time, new orders must use the new increments or they will be rejected. Since each revised increment divides the old one, orders already aligned to the previous tick size remain aligned to the new size. The exchange says the change applies to new and existing orders but does not alter open positions. This is an operational exchange notice, not an analysis of market impact: it provides no evidence on spreads, liquidity, execution quality, or realized volume, and traders are advised to update their systems.

Key ideas

• The update reduces tick sizes for nine linear USDC perpetual contracts.
• The revised increments apply to order books and block trades.
• New orders using invalid price increments will be rejected after the change takes effect.
• Orders conforming to the old increments also conform to the smaller new increments.
• Open positions are unaffected, while order handling and trading systems may need adjustment.
