Binance tightens market making rules after October crash criticism
Binance, the world’s largest crypto exchange, said it is tightening market making rules for token issuers and liquidity providers after criticism of market practices during October’s crash. In a new blog post, Binance said crypto projects must not use revenue-sharing models with market makers. It also said market makers cannot work with projects in ways that manipulate prices or distort token liquidity.
Binance warned it will take “swift, decisive action” against any misconduct, including blacklisting market makers. For traders, this move targets the structure of liquidity provision and seeks to reduce conflicts of interest that can worsen volatility during drawdowns.
Binance market making rules now appear likely to change how liquidity is sourced across affected tokens, potentially tightening spreads for some pairs, while also increasing short-term uncertainty around liquidity depth as market makers adapt.

该消息对市场的方向性影响偏“中性”。一方面，币安市场做市商规则重点打击“收益分成”与“操纵价格/扭曲流动性”的潜在利益冲突。此类合规升级通常有助于提升市场诚信，长期可能降低极端行情下的流动性崩坏概率，从而对波动形成结构性缓冲——类似于交易所在重大风控事件后加强做市/对手方约束的历史做法。
另一方面，规则可能在短期引发流动性再配置：部分做市商可能因黑名单风险或合规成本上升而调整覆盖范围，导致个别代币的深度与点差在过渡期波动。这种“流动性阶段性收缩”在以往的市场整顿周期里并不少见，短期可能增加部分交易对的滑点和波动。
对交易者的直接含义：关注币安相关公告后，受影响代币的成交量、挂单深度、点差以及波动率变化；若出现流动性下降但价格未同步下跌，可能带来“价差/滑点”交易机会；若监管或违规事件引发市场恐慌，则可能短期偏向风险规避。
