Binance has announced modifications to collateral ratios for certain assets under Portfolio Margin and PM Pro, alongside updated leverage and margin tiers for SOLUSD and XRPUSD COIN-M Perpetual Contracts. These changes will take effect on September 2 and September 5, 2025, as detailed in a press release.
According to Binance, these updates are part of its ongoing risk management strategy. The adjustments aim to align margin requirements with market dynamics while protecting users from volatility. Changes to collateral ratios affect the Unified Maintenance Margin Ratio (uniMMR), which determines users’ liquidation thresholds. Binance describes these changes as proactive measures to enhance platform stability and resilience in dynamic market conditions.
On September 2, 2025, at 06:00 UTC, Binance increased collateral ratios for assets under Portfolio Margin such as BERA, RAY, and ONDO from 30% to 50%, CATI and EIGEN from 20% to 30%, and floored allocations like NMR, STG, BICO, WCT, and RED from 10% to 30%. On September 5, the ratios for KAVA, IOTA, 1INCH, TWT, SFP, and SNX were reduced—from 50% down to between 25–40%, depending on the asset—reflecting a nuanced calibration of asset leverage profiles. Additionally, Binance’s PM Pro Tier structure for UNI and TON was realigned: Tier allocation was elevated from Rank 9 to Rank 7.
