Binance Updates Margin and Leverage Rules: Multi-Asset Collateral Ratio Lowered, Multi-Coin Futures Leverage Synced Adjustment

**Binance to Update Portfolio Margin, Adjust USDⓈ-M Perpetual Leverage & Margin Tiers Starting June 19, 2026** Binance announced on June 17 that the platform will roll out updates to its Portfolio Margin cross-asset rate effective June 19, 2026, alongside revisions to the leverage and margin tier structure for multiple USDⓈ-M perpetual contracts. The entire adjustment is projected to take 30 to 60 minutes to complete. On the Portfolio Margin front, collateral rates for assets ADA and FDUSD are being reduced. ADA’s collateral rate will drop from 90% to 85%, while FDUSD’s collateral ratios across different position tiers will also be cut. The exchange noted this change will impact the Unified Maintenance Margin Rate (uniMMR), urging users to monitor evolving risks to avoid potential liquidations. For USDⓈ-M perpetual contracts, leverage and margin tiers for trading pairs including SIREN, VELVET, RESOLV, TRUST, THE, MAV, SANTOS, ORDI, DIA, and INX are being updated simultaneously. For most of these coins, Binance is compressing their high-leverage range—either by increasing maintenance margin rates or lowering maximum leverage multiples—to mitigate the platform’s risk exposure during extreme market volatility. The update will go into effect at 06:30 UTC on June 19. System modifications may affect existing positions and grid trading strategy operations, with some strategies requiring manual adjustments from users in advance. Binance stated the overhaul is designed to refine its risk control framework and boost overall market stability.
