Binance has announced major changes coming to the collateral ratios and leverage tiers for various assets under its Portfolio Margin (PM) and PM Pro platforms, starting on October 21st, 2025. These updates will be implemented in two phases: first, on October 21st, assets such as PAXG, GALA, VET, GMT, QNT, XTZ, EGLD, FLOW, IOTX, KAVA, and IOTA will see their collateral ratios adjusted downward, impacting several assets’ existing margin requirements. On October 24th, further adjustments will be made to PM Pro assets like ORDI, FIL, NOT, GALA, GMT, EGLD, THETA, and XTZ, incorporating both rank floor and cap adjustments alongside changes in collateral ratios. Additionally, Binance Futures will update leverage and margin tiers for several USD-M Perpetual Contracts at 06:30 (UTC) on the same day. Users are advised to review their Unified Maintenance Margin Ratio (uniMMR) closely to mitigate risks from these updates.
