What Is Binance's Unified Margin Mode?
Binance's Unified Margin Mode expands the types of margin available for USDⓈ-Margin contracts, allowing users to trade USDⓈ-Margin contracts across multiple margin assets.
Currently, Binance offers two types of USDⓈ-Margin contracts: USDT contracts and BUSD contracts. With the Unified Margin Mode, users can share margin between USDT and BUSD contracts.
Key Features:
- All margin assets are converted to USD valuation.
- USDT and BUSD assets in the USDⓈ-Margin account serve as shared collateral.
- Profits and losses between USDT and BUSD positions offset each other, improving capital efficiency.
⚠️ Note:
- This feature currently only supports Cross Margin Mode.
- You cannot enable/disable Unified Margin if you have open positions or pending orders.
- If you prefer using a single margin asset, select Single-Asset Mode.
How to Switch Between Single-Asset and Unified Margin Mode
- Go to Binance's USDⓈ-Margin trading page.
- Click Preferences (⚙️) > Margin Mode.
- Select Single-Asset Mode or Unified Margin Mode.
🔹 Default Mode: Single-Asset Mode (no margin sharing between assets).
🔹 Unified Margin Mode applies only to USDⓈ-Margin contracts.
Restrictions:
❌ You cannot change the margin mode if you have:
- Open positions
- Pending orders
- Active grid trading bots
💡 Tip: Before activating Unified Margin, carefully read Binance’s risk warning—this mode increases capital efficiency but also amplifies risk.
How to Check Your Current Margin Mode
If Unified Margin is active, a "Unified Margin" label will appear in the top-right corner of the Margin Risk Ratio page.
Margin Ratio Formula:
Margin Ratio = Account Maintenance Margin / Account Equity - Account Maintenance Margin: Sum of maintenance margins for all positions.
- Account Equity: Total USD value of all margin assets.
⚠️ Risk Alert:
- If your Margin Ratio reaches 100%, all positions will be liquidated.
How to View Asset Balances
Navigate to the Assets tab in the trading interface (next to "Funds Flow"). This section displays:
✅ Available margin assets
✅ Wallet balances
✅ Unrealized P&L
✅ Usable margin
Calculating Margin Ratio in Unified Margin Mode
Example Scenario:
| Asset | Wallet Balance | Mark Price | Unrealized P&L | Equity |
|--------|----------------|------------|-----------------|--------|
| USDT | 200 | 0.99 | -500 | -300 |
| BUSD | 220 | 1.00 | +400 | 620 |
- Account Equity = (-300 × 0.99495) + (620 × 1.00) = 321.515 USD
Maintenance Margin = (Position Size × Mark Price × Maintenance Rate × Ask Rate)
- BTCUSDT:
0.5 × 19,000 × 0.008 × 0.99495 = 75.62 - ETHBUSD:
20 × 620 × 0.01 × 1.00 = 124.00 - Total = 199.62 USD
- BTCUSDT:
- Margin Ratio =
199.62 / 321.515 = 62.08%
👉 Takeaway: Unified Margin dynamically adjusts available balance based on cross-position risk.
Automatic Conversion Mechanism
If an asset balance falls below a threshold, Binance automatically converts other USDⓈ-Margin assets to cover the shortfall.
🔹 Conversions occur at fixed intervals.
🔹 Excess funds are exchanged to replenish the deficit.
Maximum Withdrawable Amount
When no margin is used:
Max Withdrawal = Wallet Balance - Maintenance Margin - Borrowed Amounts When Unified Margin is active:
- Calculate virtual USD value.
- Convert to margin asset(s) based on exchange rates.
- Compare against wallet balance and net equity.
💡 Pro Tip: Monitor your Margin Ratio closely to avoid liquidation.
