Dear Binance Users,

We’re announcing key updates to Portfolio Margin collateral ratios and USDⓈ-M Perpetual Contracts leverage tiers, effective 2025-06-13.

1. Portfolio Margin Collateral Ratio Changes

Selected assets (e.g., XLM, ATOM, ALICE, COS) will have adjusted collateral ratios. Example reductions:

XLM: 85% → 80%

COS: 30% → 15%

NEO: 70% → 55%

Action Required: Monitor your Unified Maintenance Margin Ratio (uniMMR) to avoid liquidation risks.

2. USDⓈ-M Perpetual Contracts Updates

Leverage & margin tiers for 16 contracts (e.g., ATOMUSDT,

ALICEUSDT, KAVAUSDT) will be revised. Key changes:

Position size brackets and maintenance margin rates adjusted for higher flexibility.

Example: ATOMUSDT max leverage reduced from 75x to 50x for positions ≤$5,000.

Note: Existing positions will be affected. Futures grid bots may expire—adjust strategies beforehand.
