Futures Contracts: Leverage & Margin Tier Adjustment Notice

Effective Date: October 27, 2025

Overview

To better maintain a high-quality trading market and adapt to dynamic risk management protocols, Koinbay is updating the leverage and margin tiers for several USDT-margined perpetual contracts, namely:

• ETH/USDT

• BNB/USDT

• XRP/USDT

Users with open positions in these contracts will be affected. Please review your margin ratio and position size to avoid potential forced liquidations.
