Cross Margin vs Isolated Margin on Binance Futures – What's the Difference?

Cross or Isolated — which margin mode should you use when opening a futures position? This choice directly determines your liquidation rules and risk exposure. Getting it wrong could mean losing more than expected. This article uses concrete examples to clarify. If you don't have a Binance account yet, sign up for Binance first.

One-Line Summary

• Isolated: Each position uses its own margin. If it's gone, it's gone — other funds untouched
• Cross: All positions share your entire futures account balance as margin. Harder to liquidate, but losses can be much larger

Isolated Mode Explained

How It Works

When you open an isolated position, the margin you assign is locked to that position. This margin is your maximum possible loss.

Example

Futures account balance: 1,000 USDT

You use 100 USDT margin, 10x leverage, long BTC:

• Position value: 1,000 USDT
• Margin: 100 USDT
• Remaining available: 900 USDT

If BTC drops 10%:

• Loss = 1,000 x 10% = 100 USDT
• 100 USDT margin fully consumed → Liquidated
• Your 900 USDT balance is unaffected
• Total loss: 100 USDT

Isolated Characteristics

• Maximum loss = assigned margin
• Liquidation doesn't affect other funds
• Liquidation price is fixed and predictable
• You can manually add margin to delay liquidation

Cross Mode Explained

How It Works

In Cross mode, your entire futures account balance automatically serves as margin for all positions. Even a small position is backed by your full balance.

Example

Futures account balance: 1,000 USDT

You use 100 USDT margin, 10x leverage, long BTC (Cross mode):

• Position value: 1,000 USDT
• Initial margin: 100 USDT
• Effective margin: 1,000 USDT (entire balance)

If BTC drops 10%:

• Loss = 1,000 x 10% = 100 USDT
• Cross mode auto-replenishes margin from the balance
• Not liquidated — balance drops to 900 USDT

If BTC keeps falling until all 1,000 USDT is consumed → liquidation with 1,000 USDT total loss.

Side-by-Side Comparison

1,000 USDT account, 100 USDT margin, 10x leverage, long BTC:

When to Use Isolated

1. Beginners

Risk is controllable — you can only lose the assigned margin. Protects most of your capital while learning.

2. High Leverage Trading

With 20x+ leverage, use Isolated for safety. Small moves can liquidate, but losses are capped.

3. Clear Risk Management

You know exactly your maximum loss at entry, making position sizing straightforward.

4. Multiple Positions

Running long BTC and long ETH simultaneously? Isolated prevents one liquidation from destroying the other.

When to Use Cross

1. Longer-Term Positions

If you're holding a directional position with conviction, Cross mode prevents short-term volatility from knocking you out.

2. Low Leverage

At 1–3x leverage, Cross mode liquidation risk is very low, and capital efficiency is better.

3. Hedging

When running opposing positions (one long, one short), Cross mode lets gains and losses offset each other.

4. Experienced Traders

After understanding Cross risks, experienced traders can leverage the improved capital efficiency.

How to Switch

1. Open the futures trading page
2. Tap the "Isolated" or "Cross" label next to the margin mode
3. Select the mode you want
4. Confirm

Note: You can't switch modes on a pair with open positions — close positions first.

Recommendations by Trader Type

When in doubt, default to Isolated. It liquidates more easily, but the damage is limited to what you chose upfront. Once you deeply understand futures, experiment with Cross as needed.
