2025-01-28 03:34:24In a Unified Trading Account, all supported collateral assets are valued in USD. This USD value serves as the margin balance, which can be used for trading. Due to varying liquidity conditions of each crypto asset, these assets may be valued at a discounted rate using a "Collateral Value Ratio." This ratio determines the percentage at which an asset is recognized as collateral.
How Collateral Value Ratio Affect Margin Balance
In Cross Margin mode, the Margin Balance is calculated as:
Margin Balance = Wallet Balance + Perp & Future Unrealized Profit/Loss (UPL)
If there are no positions or orders in your account, the margin balance is calculated as:
Total Wallet Balance (in USD) = Sum (Asset 1 × USD Index Price × Collateral Value Ratio + Asset 2 × USD Index Price × Collateral Value Ratio + … + Asset N × USD Index Price × Collateral Value Ratio)
Whereas,
USD Index Price = USDT Perpetual Index Price x USDT Conversion Rate
USDT Conversion Rate = BTCUSD Index Price / BTCUSDT Index Price
Notes:
— If there is no USDT Perpetual Index Price for a particular asset, the Last Traded Price on Bybit Spot Market will be used. For example, the USD Index Price for ETH will be ETHUSDT Index Price × USDT Conversion Rate.
— The Collateral Value Ratio only applies to assets with a positive balance. For assets with a negative balance default to a 100% collateral value ratio.
— Traders can customize which assets to be served as collateral. For more information, please refer here.
Example Calculation
Assume the tiered value rates of BTC and USDT are shown as follows:

Trader A’s Unified Trading Account has the following assets:
|
Coin |
Wallet Balance |
Unrealized PnL |
Total Assets |
Index Price |
Total Margin Balance |
|
BTC |
60 |
20 |
80 |
50,000 |
(10 x 0.98 + 10 x 0.95 + 10 x 0.9 + 10 x 0.85 + 10 x 0.8 ) x 50,000 = 2,240,000 |
|
USDT |
500 |
-10,000 |
-9500 |
1 |
-9500 x 1 = -9,500 （Ratio for negative asset equal to 1） |
Total margin balance = 2,240,000-9,500 ≈ 2,230,500 USD
Therefore, the total amount available as a margin for this account is approximately 2,230,500 USD.
