What Is Cross Margin vs. Isolated Margin in Futures?
Introduction
Margin trading in crypto futures involves using borrowed funds to amplify position sizes. Two primary margin modes, cross margin and isolated margin, determine how your collateral is allocated and managed. Understanding the differences between these modes is crucial for effective risk management and optimizing your trading strategy.
This guide explains cross margin and isolated margin in crypto futures trading, their advantages and disadvantages, and how to choose the right mode for your trades.
What Is Cross Margin?
In cross margin mode, your entire account balance is shared across all open positions of the same trading pair. If one position incurs losses, the system uses the remaining margin from your account to prevent liquidation.
- Key Features**:
1. **Shared Margin**:
- Margin is pooled from your total account balance.
2. **Liquidation Risk**:
- Liquidation occurs only when your entire account balance is depleted.
3. **Flexibility**:
- Reduces the likelihood of liquidation by spreading risk across positions.
- Example**:
- Account balance: $1,000. - Long BTC/USDT position: $500 margin. - If your position nears liquidation, the remaining $500 in your account will be used to cover losses.

What Is Isolated Margin?
In isolated margin mode, only the margin allocated to a specific position is at risk. If the position’s margin is insufficient to cover losses, the position will be liquidated without affecting the rest of your account balance.
- Key Features**:
1. **Independent Margin**:
- Each position’s margin is managed separately.
2. **Controlled Risk**:
- Losses are limited to the allocated margin for the position.
3. **Higher Liquidation Risk**:
- Positions are more vulnerable to liquidation if margin levels are not actively monitored.
- Example**:
- Account balance: $1,000. - Long BTC/USDT position: $500 margin in isolated mode. - If the position reaches its liquidation price, only the $500 margin is lost, preserving the remaining $500 in your account.
