Binance has announced an update to collateral ratios for PM Pro assets under Portfolio Margin, set to take place on September 16 and 19, 2025. This will be followed by adjustments to leverage and margin tiers for USDⓈ-M Perpetual Contracts. The announcement was made through a press release.
According to the official Binance announcement published on September 11, 2025, the collateral ratio updates took effect on September 16 and September 19 at 6 a.m. UTC, with each update lasting approximately 30 minutes. The changes impacted both “Portfolio Margin” and “PM Pro” tiers, adjusting the base collateral ratio for some assets as well as the tiered collateral ratio, which varies by position size. Traders with affected assets were advised that existing positions would be impacted and should reassess their risk exposure, as collateral requirements may have increased or decreased.
On September 16, assets under Portfolio Margin experienced increases in collateral ratios: WLD’s ratio rose from 50% to 60%, and BIO’s from 20% to 30%. Under PM Pro, collateral tier floors and caps for certain assets like XRP and DOGE were modified. For example, the 100% collateral ratio tier for XRP and DOGE, which previously applied to positions up to one million USDT (United States Dollar Tether), was expanded to cover positions up to three million USDT. Additionally, collateral tiers for larger position sizes saw lower ratios, reducing collateral requirements at higher notional amounts.
On September 19, several assets saw reductions in their collateral ratios under Portfolio Margin: CELO dropped from 45% to 30%, ZIL from 40% to 30%, and DASH, ANKR, and HOT each fell from 35% to 25%. These changes reflected a rebalancing of perceived risk, with assets exhibiting higher volatility or lower liquidity requiring more buffer to ensure safer positions. As with earlier updates, existing positions were affected, prompting traders using these assets for collateral to adjust in order to maintain margin health.
According to Binance’s official profile, Binance was founded in 2017 and has become one of the world’s largest cryptocurrency exchanges by trading volume.
