According to the announcement from Binance, significant updates are scheduled for collateral ratios and tiered collateral ratios under Portfolio Margin and PM Pro. These changes will take effect on 2025-09-23 and 2025-09-26, with adjustments expected to be completed within approximately 30 minutes. On 2025-09-23, assets such as PUMP, LINEA, and KMNO will see their collateral ratios increase from 10% to 30% under Portfolio Margin. For PM Pro, assets like TRX, ONDO, and PUMP will undergo various adjustments in rank floor, cap, and collateral ratios. For instance, TRX's collateral ratio will change from 100% to 80% for positions between 200,000 and 400,000 USD, and further adjustments will be made for higher tiers. Similarly, ONDO and PUMP will experience changes across different rank floors and caps, impacting their collateral ratios significantly.

Further updates on 2025-09-26 will affect assets such as RVN, BAT, AUDIO, and KNC under Portfolio Margin, with collateral ratios decreasing to 25% or 20%. PM Pro assets like ORDI, SATS, and BOME will also see adjustments in rank floor, cap, and collateral ratios. Additionally, Binance Futures will update leverage and margin tiers for several USD-M Perpetual Contracts starting from 2025-09-20. Contracts such as ETHFIUSDT, ATHUSDT, and others will have revised leverage and margin tiers, affecting existing positions. Users are advised to adjust their positions accordingly to avoid potential liquidation or losses due to these changes. The updates will impact leverage ranges, position limits, and maintenance margin rates across various tiers. Binance emphasizes the importance of monitoring the Unified Maintenance Margin Ratio (uniMMR) closely to mitigate risks associated with these updates.
