When trading futures on Binance, you will find two margin modes to choose from: Cross and Isolated. Many beginners do not know the difference between the two and just pick one randomly to start trading, which may result in losing more money due to using the wrong mode. Switching between cross and isolated margin is very convenient on the official Binance website, but you need to understand their differences first. We recommend downloading the official Binance App to operate and adjust at any time. Apple phone users should first refer to the iOS installation guide to install the App.
What is Cross Margin Mode
Cross Margin mode means that all available balances in your futures account will be shared as margin. All positions share a single margin pool.
For example: You have 1000 USDT in your futures account, and you use 200 USDT as margin to open a BTC long position. In cross margin mode, the remaining 800 USDT will automatically serve as a backup margin for this position. If BTC drops and causes your position to lose more than 200 USDT, the system will automatically supplement the margin from the remaining 800 USDT to maintain the position.
The advantage of cross margin mode is that positions are less likely to be liquidated, because the entire account balance acts as a buffer. The disadvantage is that once liquidation occurs, you might lose all the money in your account.
What is Isolated Margin Mode
Isolated Margin mode means that the margin for each position is independent and isolated. Whatever amount of margin you allocate when opening a position is the maximum that position can use.
Using the same example: You have 1000 USDT in your futures account, and you use 200 USDT as margin to open a BTC long position. In isolated margin mode, the margin for this position is strictly 200 USDT, and the remaining 800 USDT has nothing to do with it. If BTC drops and causes a loss of more than 200 USDT, the position will be liquidated, but you only lose 200 USDT, and the remaining 800 USDT remains safe.
The advantage of isolated margin mode is that risks are controllable, and the loss of a single position will not affect other funds. The disadvantage is that the position is more likely to be liquidated because the available margin is limited.
Detailed Comparison of Cross and Isolated Margin
How Margin is Used
Cross Margin mode: All positions share the entire account balance as margin. Unrealized profits from one position can help maintain the margin for another position. Isolated Margin mode: Each position has an independent margin and they do not affect each other. A profitable position will not help another losing position.
Liquidation Risk
Cross Margin mode: Because the margin pool is large, the probability of a single position being liquidated is relatively low. However, once liquidated, you may lose the entire account balance. Isolated Margin mode: Margin is limited, making a single position more likely to be liquidated. But the maximum loss is strictly the margin of that position, and it will not affect other funds.
Suitable Scenarios
Cross Margin mode is suitable for hedging trades. For example, if you are long on BTC and short on ETH at the same time, the profit and loss of the two positions can partially offset each other, making them more efficient when sharing margin in cross mode. Cross margin is also suitable for trades where you have high confidence and want to give the position the maximum buffer room.
Isolated Margin mode is suitable for traders with strong risk management awareness. You can precisely control the maximum loss for each position. It is also suitable for simultaneously opening multiple uncorrelated positions, managing risks independently for each.
Margin Efficiency
Cross Margin mode has higher margin efficiency. Because the funds in the account are shared, you do not need to reserve margin separately for each position. With the same amount of funds, you can open more positions under cross margin mode.
Isolated Margin mode has lower margin efficiency. The margin for each position is locked and cannot be used by other positions. However, this exactly serves as a risk control measure.
How to Switch Between Cross and Isolated Margin on Binance
On the Binance futures trading page, there is a button above the order placement area displaying "Cross" or "Isolated". You can click it to switch.
Keep a few points in mind: You can only switch margin modes when you have no open positions for the corresponding trading pair. If you already have a cross margin BTCUSDT position and want to switch to isolated margin, you must close that position first. Different trading pairs can have different margin modes. You can use cross margin for BTC and isolated margin for ETH, and they will not affect each other.
Switching steps: Find the current margin mode display (Cross/Isolated) on the futures trading page and click it. Select the mode you want to switch to in the pop-up window. Confirm the switch.
How to Add Margin in Isolated Margin Mode
In isolated margin mode, if your position is close to being liquidated, you can manually add margin to reduce the risk.
How to do it: Find the position that needs additional margin in the position list, and click the edit button next to the margin amount (usually a plus sign or a pencil icon). Enter the amount of margin you want to add. Confirm the addition.
After adding margin, your liquidation price will move further away, making the position safer. But it also means you have invested more funds into this position. If it eventually gets liquidated anyway, the loss will be larger.
So think carefully before adding margin: is it because you are still confident in the direction and it is just a temporary loss, or are you just stubbornly holding a losing trade? If it is the latter, it might be better to cut your losses and exit.
Practical Scenario Analysis
Scenario 1: Beginner Single Position Trading
Xiao Ming is a beginner in futures trading. He has 500 USDT in his account and wants to use 100 USDT as margin to open a 5x leverage BTC long position.
If using Cross Margin mode: When BTC drops, the system will automatically use the remaining 400 USDT to maintain the position. In the worst-case scenario, Xiao Ming could lose the entire 500 USDT.
If using Isolated Margin mode: When BTC drops, only the 100 USDT margin is at risk. In the worst-case scenario, Xiao Ming only loses 100 USDT, and the remaining 400 USDT is safe.
For beginners, isolated margin mode is obviously safer and can help you control your losses.
Scenario 2: Multi-Position Hedging
Lao Wang is an experienced trader who goes long on BTC and short on ETH simultaneously for a hedge.
If using Cross Margin mode: The BTC and ETH positions share the margin. If both BTC and ETH rise (the short position loses money), the profit from BTC can subsidize the margin of the ETH position, making it less likely to be liquidated.
If using Isolated Margin mode: The two positions are independent. The loss of the ETH short cannot receive a margin subsidy from the profit of the BTC long, making it more likely to be liquidated.
For hedging trades, cross margin mode is more efficient.
Scenario 3: Holding Multiple Speculative Positions Simultaneously
Xiao Hong simultaneously goes long on 5 different altcoins, using high leverage for each.
If using Cross Margin mode: If just one of them crashes, it might drag down the entire account, affecting all positions.
If using Isolated Margin mode: Each position is independent. A crash in one only loses the margin of that specific position, leaving the others unaffected.
In this case, the advantage of isolated margin mode is very clear.
Practical Advice
For most traders, the following advice can be used as a reference:
Beginners should always use isolated margin mode. While you are still in the learning phase, isolated margin mode effectively protects your funds. Even if you make a mistake, the losses are controllable.
Consider cross margin mode when making hedging trades. If there is a hedging relationship between your long and short positions, cross margin mode can improve margin efficiency.
It is recommended to use isolated margin for high-leverage trades. High leverage inherently carries a huge risk of liquidation. Using isolated margin mode limits the maximum loss of a single trade.
Do not open too many uncorrelated positions in cross margin mode. Under cross margin mode, the loss of one position will affect the margin of others. If multiple positions lose money simultaneously, it could trigger a chain liquidation.
Regularly check your margin mode. When switching trading pairs, pay attention to whether it is currently cross or isolated to avoid using the wrong one.
Frequently Asked Questions
Can I switch between cross and isolated margin at any time?
Yes, provided that there are no open positions for the current trading pair. If you have an open position, you must close it before you can switch. Margin mode settings between different trading pairs do not affect each other.
Will a liquidation in isolated margin mode affect other positions?
No. In isolated margin mode, each position is independent. The liquidation of one position will only result in the loss of its own margin, and will not affect other positions or your available balance.
Can I control my maximum loss in cross margin mode?
You can control it by setting a stop-loss. Although theoretically you could lose your entire account balance in cross margin mode, if you have properly set a stop-loss, the position will automatically close when the stop price is triggered, preventing you from reaching the point of liquidation.
Which mode is more suitable for long-term holding?
If you are holding a single coin long-term, cross margin mode is more suitable because the margin buffer is large, making it less likely to be liquidated by short-term fluctuations. But you must also set a stop-loss to protect against extreme market conditions.
Can I add margin in isolated margin mode?
Yes. Find the corresponding position in the position list and click the button to add margin to manually increase it. After adding, the liquidation price will move further away, but it also means the risk exposure of that position has increased.
