In 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

Assuming Trader A currently has 1,000 USDT, 1,000 USDC, and 0.1 BTC in their Unified Trading Account.

Total Margin Balance = 995.20 + 1,000 + 1,580.78 ≈ 3,575.98 USD

Thus, the total amount that can be used as margin in this account is approximately 3,575.98 USD.

How to View The Collateral Value Ratio

Bybit will review and update the collateral value ratio periodically based on market conditions.
