What is Auto-Exchange?
Auto-Exchange is a mechanism to ensure that the USDT or USDC balances in the USDⓈ-M Futures Wallet do not fall below a certain threshold.
When Auto-Exchange is triggered, all positive balance assets under the USDⓈ-M Futures Wallet are automatically converted at market price by the Auto-Exchange service engine to cover the corresponding USDC or USDT deficit.
When will Auto-Exchange be triggered in the Multi-Assets Mode?
Under the Multi-Assets Mode, Auto-Exchange will happen under three circumstances:
1. When either the USDT or USDC wallet balance is lower than the autoExchangeThreshold (-10,000 USD), the Auto-Exchange service engine will proportionally convert other assets in the USDⓈ-M Futures Wallet to USDT or USDC to cover the deficit.
2. In case of liquidation, Auto-Exchange will be immediately triggered if the USDC or USDT balance in the USDⓈ-M Futures Wallet is insufficient to cover the deficit.
3. When there is a negative balance in your USDⓈ-M Futures Wallet with no existing positions or open orders, the system will continuously calculate the LTV (Loan-To-Value) ratio and trigger Auto-Exchange when LTV ≥ 0.995.
Note: LTV = abs(∑negative asset WalletBalance in USD value * (1 + Auto-Exchange Haircut)) / ∑positive asset WalletBalance in USD value * (1 - Auto-Exchange Haircut)
When your USDC or USDT balance in the USDⓈ-M Futures Wallet is not negative, and the wallet balance is over -10,000 USD, auto-conversion won’t happen.
Suppose either the USDC or USDT wallet balance is below -10,000 USD. In that case, other assets in the USDⓈ-M Futures Wallet will be converted to USDC or USDT to cover the deficit, deducting the corresponding margin assets amount.
Auto-Exchange can help balance your account and increase the utilization rate of funds in case of losses.
What are the Auto-Exchange haircut rates?
While Auto-Exchange doesn’t charge any fees, the following haircut rates (also referred to as the collateral rate) apply to the Auto-Exchanged assets to mitigate the liquidity risks:
Assets | Auto-Exchange Haircut |
BTC | 2.5% |
ETH | 2.5% |
BNB | 5% |
ADA | 5% |
XRP | 5% |
DOT | 5% |
SOL | 5% |
USDT | 0.01% |
USDC | 0.01% |
TUSD | 0.8% |
USDP | 0.8% |
Examples of Auto-Exchange
Example 1:
You’re trading in the Multi-Assets Mode. Your USDⓈ-M Futures Wallet has a positive BTC balance and a negative USDC balance.
Let’s assume your USDC balance falls to -20,000 USDC, which triggers the Auto-Exchange (below the -10,000 USD threshold), taking into account the 2.5% haircut rate in the process.
Subsequently, 20,000 USDC / 97.5% = 20,513 USDC of your BTC balance will be converted to USDC to cover the negative USDC balance in the USDⓈ-M Futures Wallet.
Example 2:
Under the Multi-Assets Mode, you don’t have any existing position or open order, and the USDⓈ-M Futures Wallet balance is 1 BNB + (-600) USDC
- Suppose BNB/USDC = 700 USD
Your LTV = abs(-600)/(700 * (1 - 5%)) = 0.90 < 0.995, Auto-Exchange will not be triggered;
- Suppose BNB/USDC = 600 USD
Your LTV = abs(-600)/(600 * (1 - 5%)) = 1.05 ≥ 0.995, Auto-Exchange will be triggered. Your BNB will be converted to USDC to clear the negative USDC balance.
To avoid triggering Auto-Exchange, you can convert or transfer margin assets to the USDⓈ-M Futures Wallet to maintain the negative balance below the -10,000 USD threshold. If you don't have any existing positions or open orders and there is a deficit in your USDⓈ-M Futures Wallet, you are advised to convert or transfer sufficient margin assets to the USDⓈ-M Futures Wallet in a timely manner to prevent the account LTV from going above 0.995, which would trigger Auto-Exchange.
To reduce risks, Binance may temporarily adjust the Auto-Exchange threshold and execute the conversion automatically. You may notice that the balance of a certain asset in your USDⓈ-M Futures Wallet is negative. However, this does not necessarily mean the balance of your USDⓈ-M Futures Wallet is at a loss.
