After borrowing, your assets cannot be transferred out directly. The amount "locked" in your account is larger than you might think. Once you borrow on margin, your assets are already pledged as collateral in your Margin Account. There are thresholds for transferring out — you cannot withdraw as much as you see in your balance.

First, understand where your money is
The logic of margin borrowing is to use your own assets as collateral and borrow additional funds for trading. Both the borrowed funds and your collateral are locked in your Margin Account, not in your Spot Account.
To transfer assets to your Spot Account and then withdraw them, you must first meet one condition: your Transfer Risk Rate (Transfer ML) must be above the threshold. Binance's official documentation clearly states that the Transfer Risk Rate determines the maximum amount you can transfer out of your Cross Margin Account.
Why transfers are restricted
The key indicator is the Risk Rate, which measures the relationship between your collateral value and your liabilities. If the Risk Rate is not high enough, the system considers the account riskier and directly restricts transfers.
The formula is: Transfer Risk Rate = Collateral Value / (Total Liabilities + Unpaid Interest).
Collateral value is not simply the sum of all your assets. Each coin has its own Collateral Ratio (haircut). For example, Bitcoin may have a collateral ratio of 95%, while some smaller altcoins may only be 60%-70% or even lower.
So you may see 10,000 USDT in your account, but only 6,000 USDT can be transferred out — the remaining 4,000 USDT is locked by the system as a "collateral haircut".
Risk warning: On January 21, 2026, Binance adjusted the collateral ratio parameters for Cross Margin Accounts, splitting the unified collateral ratio into three independent indicators: "Borrow Collateral Ratio, Transfer Collateral Ratio, and Liquidation Collateral Ratio". This means "how much you can borrow" and "how much you can transfer out" are now two separate standards, and the transfer threshold may be stricter than the borrowing threshold.

How to do it: First check how much you can transfer
Step 1: Check the maximum transferable amount
On the Margin Account page, find the indicator related to "Maximum Transferable" or "Transfer Risk Rate". You can only transfer funds out when the Transfer Risk Rate is above the threshold (e.g., >2 or >1.5, depending on your leverage level).
Step 2: Transfer to Spot Account before withdrawing
If the Transfer Risk Rate meets the requirement, first transfer the assets from your Margin Account to your Spot Account, then withdraw from your Spot Account. Binance's margin transfer rules clearly state: the actual maximum transferable amount is determined by the smaller of the Risk Unit Maximum Transferable Amount and the Collateral Account Maximum Transferable Amount.
Step 3: If the Transfer Risk Rate is insufficient
You can only add more collateral to your Margin Account, or repay part of your loan first to reduce total liabilities and bring the Risk Rate back up to a transferable level. There is no shortcut.
How to verify after completing the operation: On the Margin Account page, find the "Maximum Transferable" value. If it shows 0 or is lower than the amount you want to transfer, it means you cannot transfer at the moment. Only when this value is greater than 0 can you transfer assets to your Spot Account through the transfer function.
