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.
