Binance announced on its website that it updated collateral ratios for PM Pro under Portfolio Margin on October 28 and October 31, 2025. The company also revised leverage and maintenance-margin tiers for selected USDⓈ-M Perpetual Contracts, impacting existing positions.
According to Binance Support, the company adjusted collateral parameters for specific assets under Portfolio Margin and PM Pro in two phases, with each change window completing in approximately 30 minutes. Binance Support emphasized that these updates are part of ongoing risk controls and advised users to monitor their Unified Maintenance Margin Ratio (uniMMR) to avoid liquidation. It was noted that existing positions opened before the futures tier changes would be affected, advising users to adjust in advance.
On October 28, 2025, at 06:00 UTC, according to a Binance Support announcement, ZEC’s collateral ratio under Portfolio Margin increased from 20% to 30%, while FIL and ALGO fell from 70% to 50% and 60% to 50%, respectively. Further reductions were observed: A from 65% to 45%, RUNE and AR from 55% to 35%, and LUNC and THETA from 50% to 30%. Additional assets such as ICP, NEO, PNUT, SPK, CHZ, and NOT each declined by 20 percentage points (for example, ICP from 45% to 25%), reflecting differentiated haircuts across the basket.
On October 31, at the same time of day, Binance Support reported that PM Pro tiers were reprofiled with rank, floor, and cap bands. For instance, ZEC will have a collateral of 100% for notional amounts of $0–50,000. This steps down to lower percentages as the notional amount increases. The same schedule applies to RUNE and a grouped set of assets (A, LUNC, AR, CHZ), with requirements tightening as notional size grows. Additionally, Binance revised leverage and maintenance-margin tiers for several USDⓈ-M Perpetual Contracts by reducing certain high-leverage bands for smaller notionals and increasing maintenance-margin rates.
According to Binance’s official About page, the company describes itself as a leading blockchain ecosystem with a product suite that includes one of the world’s largest digital asset exchanges by trading volume. It provides spot, margin, and derivatives trading alongside research, education, and charitable initiatives for a global user base. Its mission highlights building infrastructure for the crypto economy while maintaining platform risk controls such as collateral, leverage, and margin frameworks.
