Binance has announced updates to collateral and tiered collateral ratios for PM Pro and Portfolio Margin assets, as well as adjustments to leverage and margin tiers for selected USDⓈ-M Perpetual Contracts. These changes are scheduled to occur between October 11 and 17, 2025.
According to Binance’s support announcement, the exchange will revise collateral ratios on assets under Portfolio Margin and PM Pro starting October 14, 2025, at 06:00 UTC. The updates are expected to be completed in about 30 minutes. The platform aims to dynamically manage risk and capital efficiency amid evolving market conditions. Binance warns users that existing positions may be impacted by these revisions, especially when adjustments to leverage and margin tiers are executed.
The announcement indicates that for the asset XPL under Portfolio Margin, its collateral ratio is being raised from 10% to 30%, suggesting a higher required margin buffer. Under PM Pro, tiered collateral ratios for XPL are also restructured across multiple rank brackets, with caps and floors set for USD ranges and new ratios assigned for each tier. The revised structure includes tiers giving a 100% collateral ratio for certain lower brackets, then dropping to 80%, 50%, and 20%, before a floor of 10% for large exposures.
Binance said that starting October 17, 2025, collateral ratios under Portfolio Margin will be reduced—from 40% to 25% for MASK, and from 30% to 15% for MOVR, HEI, and COTI. PM Pro structures will also be updated, including ALGO’s recalibrated collateral tiers with a full ratio for smaller exposures and lower ratios for higher ones. The notice adds that leverage and maintenance margin tiers for several USDⓈ-M Perpetual Contracts (such as COAIUSDT) will be adjusted on October 11 and October 14 with about an hour of implementation time. Binance cautions users that open positions before these changes may be affected and grid strategies could expire.
