Isolated and cross margin are two different margin modes in futures trading that directly determine how you control risk and the consequences of liquidation. Choosing the wrong mode can lead to unnecessarily large losses. This article compares both modes in detail. Visit Binance and use the Binance Official App (Apple users, refer to the iOS Installation Guide) to find the margin mode toggle in the actual trading interface.
What Is Isolated Margin?
Isolated margin means each position uses its own separate margin, independent from others. When opening a position, you allocate a specific amount of margin, and that position's maximum loss is limited to that allocated margin.
Example: You have 1,000 USDT in your futures account. You open a BTC long with 200 USDT margin (isolated mode). If this position is liquidated, you only lose 200 USDT — the remaining 800 USDT is completely unaffected.
What Is Cross Margin?
Cross margin means all available funds in your account serve as shared margin for all positions. The system automatically draws from your account balance to prevent liquidation.
Same example: You have 1,000 USDT and open a BTC long in cross margin mode. If the position loses, the system automatically supplements margin from your account balance. In extreme cases, you could lose the entire 1,000 USDT.
Core Differences
Risk Isolation
- Isolated: Each position's risk is independent; one liquidation doesn't affect others
- Cross: All positions share margin; one position's large loss can drag down the entire account
Liquidation Price
- Isolated: Liquidation price is closer (only that position's margin supports it)
- Cross: Liquidation price is further (entire account balance acts as buffer)
Capital Efficiency
- Isolated: Capital spread across positions, relatively lower efficiency
- Cross: Unified capital usage, higher efficiency, can open more positions
When to Use Isolated vs Cross
Use isolated when:
- You're new to futures trading
- You want strict control over maximum loss per trade
- You're trading multiple tokens and want risk isolation
- You're using higher leverage
Use cross when:
- You have extensive futures trading experience
- You only trade 1–2 tokens
- You're using lower leverage
- You have hedging strategies requiring coordinated positions
Practical Advice
- Beginners: always use isolated — protect your capital until consistently profitable
- Check mode before each trade — some exchanges may default to undesired mode
- Allocate margin wisely in isolated — don't over-allocate to a single position
- Control total exposure in cross — ensure total risk across all positions is manageable
FAQ
Can I switch between isolated and cross?
Without open positions, switch freely. With open positions, some exchanges allow switching, but it changes liquidation prices — proceed carefully.
Can I add margin to an isolated position?
Yes. Find the position in your portfolio and click the add-margin button. Adding margin pushes the liquidation price further away.
In cross mode, does one liquidation affect others?
Yes. Since all positions share margin, one position's large loss depletes account balance, potentially pushing other positions toward liquidation.
Which mode has lower fees?
Fees are unrelated to margin mode — they depend only on order type (market/limit) and your VIP level.
Safety Tips
- Beginners are strongly advised to use isolated margin to prevent one trade from wiping out all funds
- Ensure adequate risk management skills before using cross margin
- Monitor margin ratio and liquidation price via the Binance Official App
- Always set stop-loss regardless of mode
- Regularly verify your margin mode settings to avoid accidental misconfiguration
