As a risk control measure and to prevent users from forced liquidation or losses, Binance Margin trading has launched a maximum collateral limit rule for each Margin asset.

This rule sets a maximum amount of collateral for each token in all Binance Margin accounts. When the total amount of assets falls below the upper limit, users can transfer in or “top up” assets as collateral. When the total amount of a specific token reaches the set percentage of the upper limit, users can only transfer a fixed amount of assets as collateral (this number is set by Binance, such as 50,000 USDT equivalent). When the total amount of assets exceeds the upper limit, assets cannot be transferred in.


Max Collateral Rule for Margin Assets

Upper Limit / Ratio* of current total amount of assetsTransfer-in limit per tokenNote
< 80%Transfer in up to 80%* upper limit
80% - 90%50,000 USDT equivalent valueThe amount can be updated according to account’s risk status
90% - 100%Only transfer in up to the upper limit with the max capped at 50,000 USDT equivalent value
> 100%Transfer in blocked

*The ratio applies to the total amount of assets held by all Margin accounts (excluding Isolated Margin), not just one specific user account.

Please note:

  • The rule is only applicable to assets with the number of 7, 8, 9, 10 to set the upper limit according to the Cross Margin Collateral Ratio.
  • The rule is only applicable to the following Margin accounts: Cross Margin Classic, Cross Margin Pro, and Portfolio Margin.
  • Isolated Margin accounts are excluded from this rule.


Examples of collateral rules applied

The following examples illustrate the transfer limitations in the case of different asset totals across applicable Margin accounts.

Example 1: Upper limit / ratio of < 80%

The upper limit of Asset 1 is 1,000,000. User 1 transferred 500,000 into his Margin account and User 2 can continue to transfer in the max of 300,000 Asset 1 (1,000,000 * 80% - 500,000).

Under such circumstances, User 3 can only transfer up to 50,000 USDT equivalent value of Asset 1 into his Margin account because the limit ratio reaches 80%.

Example 2: Upper limit / ratio of > 80%

The upper limit of Asset 2 is 2,000,000. User 1 transferred 1,700,000 into his Margin account. The ratio of total assets / upper limit is 85%, which is greater than 80%. Therefore User 2 can only transfer up to 50,000 value of Asset 2 into his Margin account.

Example 3: Upper limit / ratio of > 100%

The upper limit of Asset 3 is 3,000,000. If the total amount of Asset 3 across all Margin accounts reaches 2,990,000 and User 1 wants to transfer another 50,000 value of Asset 3 into any of his Margin accounts, he will be notified that “Asset 3 has reached platform max pledged collateral amount. The max transfer-in quantity is 10,000. Please reduce the quantity or try with other tokens”.


Frequently Asked Questions

1. If I want to transfer in stablecoins, BTC or ETH into my Margin account as collateral , will these assets be affected by the max collateral limit rule?

The rule is only applicable to the assets with the number of 7, 8, 9, 10 (refer to the Cross Margin Collateral Ratio) and the other tiered assets, including stablecoins, BTC and ETH, will not be affected.

2. Can I transfer assets valued above 50,000USDT-equivalent to my Margin account?

You can keep transferring the asset into your margin account until the maximum cap (upper limit) is reached.

3. Can I transfer assets even after the upper limit has been reached, as collateral to prevent liquidation since the risk ratio is low to the liquidation ratio?

If the asset total cap reaches the upper limit, users will not be allowed to transfer in any more as collateral to the Margin account. You will have to transfer other assets into your Margin account as collateral.

4. Does the max collateral limit rule affect the auto-transfer function?

Yes. This rule can affect the auto-transfer function in the case an upper limit is reached. Then, the user will have to opt for other assets to be transferred into the account as collateral.
