In today's dynamic digital asset landscape, efficient risk management and capital utilization are paramount. One powerful mechanism enabling both is multi-currency collateral mode with cross margin trading. This advanced feature allows traders to maximize their trading potential by using a diversified portfolio of assets as collateral across multiple financial instruments — all while maintaining a unified risk profile measured in USD.
Whether you're engaging in spot trading, futures, perpetual contracts, or options, multi-currency cross margin streamlines your strategy and enhances flexibility. Let’s dive into how it works, its core rules, risk evaluation mechanisms, and practical implications for traders.
How Multi-Currency Collateral Works
In multi-currency collateral mode, users deposit various digital assets into a unified margin account. These assets — such as BTC, ETH, USDT, or even lesser-known tokens like ZRX — are automatically converted into USD-equivalent value based on real-time market prices and liquidity-adjusted discount rates. This USD-denominated value serves as the basis for margin requirements when opening or maintaining positions.
The system calculates your total adjusted equity — the net worth of your account after applying discount factors to each asset — which determines whether your positions remain secure or face liquidation.

Key Benefits:
- Unified collateral pool: Use BTC, ETH, stablecoins, and more as joint security.
- Cross-product access: Trade spot, futures, perpetuals, and options under one integrated margin framework.
- USD-based risk tracking: All risks and margin levels are evaluated in USD for consistency.
- Flexible borrowing options: Enable automatic borrowing to open trades even when specific coin balances are low.
Understanding Discount Rates and Asset Valuation
Not all cryptocurrencies offer the same level of liquidity or stability. To account for this, platforms apply currency discount rates — also known as haircut percentages — to reflect the relative risk of each asset.
These discount rates reduce the effective USD value of deposited assets based on their market depth, volatility, and reliability. Higher liquidity assets (e.g., BTC, ETH) typically have lower haircuts (or none), while less-traded tokens face steeper reductions.
Example: Calculating Adjusted Equity
Suppose your account holds:
- 1 BTC (index price: $50,000; discount rate: 100%)
- 50,000 ZRX (ZRX/BTC pair available; discount rate: 0%)
Since ZRX has no direct USD index but trades against BTC:
- Convert ZRX to BTC first via current spot rate
- Then multiply by BTC/USD index
- Apply ZRX’s 0% discount rate → full value retained only if highly liquid
Thus:
Adjusted equity = (1 × $50,000 × 1.0) + (value of ZRX in USD × 0) = $50,000
This means only BTC contributes usable margin, highlighting how low-discount or zero-discount assets may not bolster your position strength.
Another scenario:
You hold 11 million USDT, where:
- First 5M USDT: 100% discount rate
- Next 5M USDT: 97.5%
- Final 1M USDT: 97.5%
Adjusted equity = (5M × $1 × 1) + (6M × $1 × 0.975) = $10.85 million
This tiered structure ensures risk control at scale.
Trading Rules in Multi-Currency Cross Margin Mode
Users can choose between cross margin (shared collateral) or isolated margin (dedicated per-position collateral). Within cross margin mode, two key settings govern trading behavior:
1. Automatic Borrowing Enabled
When enabled:
- You can sell an asset or trade derivatives even if your balance of that currency is insufficient.
- If your equity in a specific coin drops below zero due to overselling or losses, the system creates a negative balance (debt).
- Interest accrues only on actual debt amounts.
- The platform uses your overall adjusted equity to meet initial margin requirements for potential loans.
For example:
- You attempt to short 20 DASH at $5 each, but only have 10 DASH.
- System allows the trade if total adjusted equity covers the $100 notional + required initial margin (e.g., 10% → $10).
- A potential loan of 10 DASH is created, secured by your available equity.
Initial margin for potential loan = Loan amount × Initial margin rate × Spot price
2. No-Borrow Mode (Manual Control)
If automatic borrowing is disabled:
- You can only trade using available balances.
- However, losses in one currency can still be covered by surplus equity in others, provided total adjusted equity remains sufficient.
- If liability exceeds the interest-free threshold, a TWAP (Time-Weighted Average Price) forced repayment is triggered.
- The system sells positive-balance assets into USDT and repays the debt automatically.
This protects solvency without immediate liquidation.

Risk Assessment: Pre-Liquidation & Order Cancellation Checks
To prevent sudden account collapse, the system employs a two-tier risk evaluation framework:
Tier 1: Order Cancellation Check
Before executing new orders, the platform verifies:
Adjusted Equity ≥ Maintenance Margin + Initial Margin for Pending Orders + Estimated Fees
If this condition fails:
- All pending futures, perpetuals, and options orders are canceled.
- In "no-borrow" mode: If usable balance < 0, isolated position openings, call options buys, and spot sells are canceled.
- In "auto-borrow" mode: If debt exceeds max borrow limit, any order increasing debt is canceled.
This early intervention prevents over-leveraging.
Tier 2: Pre-Liquidation Evaluation
Liquidation risk is assessed via the margin ratio, defined as:
Margin Ratio = Adjusted Equity / Required Maintenance Margin
Triggers:
- ≤ 300%: Early warning issued (adjustable by platform)
- ≤ 100%: Liquidation process begins after canceling pending orders
If post-cancellation margin ratio remains ≤ 100%, partial liquidation starts.
Partial Liquidation Process (Three Stages)
To minimize impact and preserve capital where possible, liquidation occurs in stages:
Stage 1: Offset Opposite Positions
The system first closes opposing positions within the same contract (e.g., long and short futures on BTCUSD).
Stage 2: Delta-Neutral Risk Reduction
If risk persists, the platform reduces offsetting positions with opposite Delta values (Delta reflects sensitivity to underlying price changes). It prioritizes closing positions with higher maintenance margins.
Example: Long futures vs. short call options on BTC — both hedge each other. System closes the costlier-to-maintain side first.
Stage 3: Non-Hedged Position Reduction
When no internal hedges exist, the system targets positions contributing most to net risk. Each is partially closed incrementally until safety is restored.
Note: Long options positions are not subject to partial liquidation due to limited downside.
If liquidation results in negative equity, the insurance fund covers the shortfall, and a bankruptcy loss invoice is generated.
Frequently Asked Questions (FAQ)
Q1: What is multi-currency collateral mode?
It’s a trading setup where multiple cryptocurrencies serve as joint collateral for leveraged positions across spot, futures, and options markets. All values are converted to USD equivalents using liquidity-based discount rates.
Q2: How does automatic borrowing work?
When enabled, you can trade beyond your current coin balance. The system creates a temporary loan if your adjusted equity supports it. Interest applies only when actual debt occurs.
Q3: Why are discount rates applied to certain coins?
Discounts reflect market liquidity and volatility. Less-tradable assets pose higher risk during downturns, so their contribution to margin capacity is reduced accordingly.
Q4: Can I lose more than I deposit?
No. Losses beyond your equity are absorbed by the insurance fund. You cannot incur personal debt beyond your deposited capital.
Q5: What triggers forced repayment (TWAP)?
When your liability in a currency exceeds its interest-free threshold in no-borrow mode, the system initiates automated repayment by selling other assets into USDT.
Q6: Are long options ever liquidated?
No. Since long options have capped downside (premium paid), they are excluded from partial liquidation processes.
Final Thoughts
Multi-currency cross margin trading offers unparalleled flexibility for experienced traders seeking efficient capital allocation. By leveraging diverse assets as unified collateral and enabling smart borrowing mechanisms, it removes friction between different product types and enhances strategic agility.
However, with greater power comes increased complexity. Understanding discount rates, margin ratios, and liquidation logic is essential to avoid unexpected outcomes.
