Binance will update the mortgage ratio and leverage rating of portfolio margin and futures contracts

The mortgage rate and ladder mortgage rate under the portfolio margin and PM Pro model will be significantly updated. These changes will take effect on September 23, 2025 and September 26, 2025, and the adjustments are expected to be completed within about 30 minutes. On September 23, 2025, the mortgage ratio of assets such as PUMP, LINEA and KMNO under the portfolio margin model will be raised from 10% to 30%. In PM Pro mode, the lower limit, upper limit and mortgage ratio of assets such as TRX, ONDO and PUMP will be adjusted severally. For example, TRX's mortgage ratio will be adjusted from 100% to 80% of the $200,000 to $400,000 positions, and higher-level positions will be further adjusted.

In addition, the Binance Contract Trading Platform will update the leverage and margin levels of multiple USD-M perpetual contracts starting from September 20, 2025.

It is recommended that users adjust their positions accordingly to avoid potential liquidation or losses caused by these changes. This update will affect different levels of leverage range, position limit and maintenance margin ratio. Binance stressed the importance of closely following the unified maintenance margin ratio (uniMMR) to reduce the risks associated with these updates.
