How Exchange Collateral Haircuts Work
In Unified Margin and Cross-Margin systems, exchanges allow you to deposit assets like BTC, ETH, and SOL as collateral to trade perpetual contracts. To protect themselves from price drops in your collateral, exchanges apply a 'haircut' discount when valuing your account equity.
The Haircut Calculation:
If you deposit $10,000 worth of SOL with a 30% haircut, the exchange recognizes only $7,000 as effective margin collateral.
The Danger of Double-Sided Liquidation
If you hold altcoin collateral and use it to open long perpetual positions, you face double-sided drawdown: as the market drops, your long position loses money while your collateral value declines simultaneously. When exchange risk engines increase haircut tiers during high volatility, positions can liquidate prematurely.
Best Practices for Collateral Management
- Keep your account Initial Margin Ratio (IMR) below 50% of total available collateral.
- Always post primary collateral in fiat-backed stablecoins (USDC) rather than volatile altcoins.
- Set automated email and webhook alerts when account Maintenance Margin usage exceeds 65%.
