Portfolio Margin Mode represents a sophisticated, risk-based margin framework designed for advanced traders seeking capital efficiency across multiple financial instruments. By consolidating positions in spot, margin, perpetual futures, futures, and options trading under a single account, this system dynamically evaluates risk exposure and reduces overall margin requirements. It allows traders to leverage their entire portfolio’s value—calculated in USD equivalents—for greater flexibility and optimized capital allocation.
This comprehensive guide breaks down how Portfolio Margin Mode works, its core mechanics, risk modeling, liquidation protocols, and practical usage strategies—all while maintaining compliance with strict risk management standards.
Understanding Portfolio Margin Mode
Portfolio Margin Mode operates on a unified risk model that aggregates all trading activities across different markets. Instead of treating each instrument in isolation, it combines spot holdings, derivative positions, and open orders into consolidated risk units based on underlying assets (e.g., BTC, ETH). This consolidation enables cross-margin functionality—where gains or hedges in one area can offset risks in another—leading to lower required margin and improved capital utilization.
All asset values are converted into USD equivalents using real-time index prices, ensuring consistent valuation across diverse cryptocurrencies and trading pairs.

Eligibility Requirements
To access Portfolio Margin Mode, users must meet two key criteria:
- Maintain a minimum net portfolio value of $10,000 USD.
- Confirm understanding of the mode’s risk implications through an educational acknowledgment process.
These requirements ensure only experienced traders with sufficient capital engage in this advanced trading environment.
Risk Unit Consolidation Explained
A cornerstone of Portfolio Margin Mode is risk unit consolidation, where all derivatives and spot positions tied to the same base asset are grouped together for margin calculation.
For example, in an ETH risk unit:
- Spot ETH/USDT and ETH/USDC trades
- Perpetual futures ETH-USDT, ETH-USDC
- Quarterly futures ETH-USD
- ETH options contracts
…are all combined into a single risk bucket. This integration allows the system to recognize hedging relationships—such as holding spot ETH while shorting ETH futures—and apply reduced margin requirements accordingly.
Automatic Inclusion of Spot Assets
Spot positions are now automatically included in the relevant risk unit. If a trader holds both spot assets and offsetting derivatives (e.g., long spot ETH and short ETH futures), the system recognizes this hedge and lowers the total margin demand proportionally.
How Portfolio Margin Is Calculated
The margin requirement in Portfolio Margin Mode is determined by evaluating the Maximum Maximum Risk (MMR) across various market stress scenarios. MMR represents the worst-case loss within predefined market shocks for each risk unit. These individual MMRs are summed up and converted into USD to derive the total portfolio MMR.
From there, the Initial Margin Requirement (IMR) is calculated as:
IMR = 1.3 × MMR_derivatives + IMR_loans
Key Components of Portfolio Margin
- Derivatives MMR
Computed by simulating extreme market conditions across six primary risk factors (MR1–MR6), plus minimum fees (MR7) and stablecoin depeg risk (MR9). - Loan MMR (MR8)
Accounts for potential borrowing needs when available balance in a specific currency is insufficient. - Consolidated MMR
Final portfolio margin = Derivatives MMR + Loan MMR
Core Risk Metrics (MR1–MR9)
Each risk metric models a different type of market stress:
MR1: Spot Price Shock
Simulates price moves (±4% to ±25% depending on asset) combined with volatility changes. Evaluates 21 scenarios (7 price shocks × 3 volatility shifts) and takes the maximum loss.
| Asset Group | Max Price Move |
|---|---|
| BTC, ETH | ±12% |
| Mid-tier (SOL, XRP, etc.) | ±18% |
| Others | ±25% |
MR2: Theta Risk (Options Only)
Measures time decay over 24 hours assuming no price or volatility change.
MR3: Vega Term Structure Risk (Options Only)
Captures differences in implied volatility impact across options with varying expiries.
MR4: Basis Risk
Models divergence between spot and futures prices. Incorporates time-to-expiry and expected volatility.
Basis = Futures Price – Spot Price
Greater time to expiry increases basis volatility, raising hedging uncertainty.
MR5: Interest Rate Risk (Options Only)
Uses Principal Component Analysis (PCA) to simulate yield curve shifts (parallel and slope changes) affecting option pricing.
MR6: Extreme Market Movement
Applies double the largest spot shock from MR1 (e.g., ±24% for BTC), capturing black-swan events.
MR7: Minimum Fee Charge
Covers slippage and taker fees during liquidation. Scales with position size via a scaling factor that increases with larger base fees.
MR8: Loan Margin Requirement
Calculates margin needed for potential currency deficits due to:
- Margin loans
- Derivative PnL losses
- Estimated trading fees
- Isolated margin orders
Two modes: Auto-loan (allows borrowing if total USD capital suffices) and No-loan (restricts trading to available balances).
MR9: Stablecoin Depeg Risk
Evaluates cross-currency hedging exposure between USDT, USDC, and USD. Applies tiered rate tables based on:
- Cross-hedging volume
- Index price deviation (e.g., USDT/USD < 0.99)
Higher depeg levels trigger exponentially increasing margin charges—up to 40% at severe depegs (<0.8).
Portfolio Margin Level Calculation
The Portfolio Margin Ratio determines account health:
Margin Level (%) = (Portfolio Value in USD) / (Total MMR in USD)
- Warning Level: Below 300%
- Liquidation Trigger: At or below 100%
- Safe Zone: Above 110%
Liquidation proceeds step-by-step until safety is restored or all positions are closed.
Liquidation Process in Portfolio Margin Mode
When margin levels fall below 100%, the system initiates a structured liquidation sequence:
Step 1: Dynamic Delta Hedging (DDH1)
Activates when MR9 (stablecoin depeg risk) dominates. Adjusts perpetual or futures positions to hedge against depeg shocks.
Step 2: General Dynamic Hedging (DDH2)
Used when spot shock risk (MR1) is highest (e.g., BTC drops 15%). Modifies futures exposure to reduce delta.
Step 3: Basis Risk Hedging
Reduces basis risk (MR4) by closing expiring futures contracts across different maturities simultaneously.
Step 4: Position Reduction
If prior steps fail, the system begins closing high-risk positions—prioritizing those that most effectively reduce MMR—until the account returns to a safe state (>110%).
Practical Tools for Testing and Monitoring
Traders can simulate margin impact before placing trades using:

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of Portfolio Margin Mode?
It significantly improves capital efficiency by recognizing offsetting positions across spot and derivatives, reducing required margin through intelligent risk aggregation.
Q2: Can I use stablecoins like USDT and USDC interchangeably in hedging?
Yes, but cross-margin hedging introduces depeg risk (MR9). Large hedges between USDT and USD will incur higher margin charges if depeg risk rises.
Q3: How does auto-loan work?
In auto-loan mode, you can trade even if your balance in a specific currency is zero—provided your total portfolio value supports it. The system creates a "potential loan," which becomes real debt if your balance goes negative.
Q4: What happens if a stablecoin depegs?
The system increases margin requirements via MR9 calculations. Severe depegs (e.g., USDT = $0.85) could trigger large margin calls or liquidations if not hedged properly.
Q5: Are options fully supported?
Yes. Options are integrated into risk units and evaluated for theta, vega, interest rate, and volatility risks—making this one of the most comprehensive options-friendly margin systems available.
Q6: How often are risk parameters updated?
Risk models adapt dynamically based on market conditions. Parameters like volatility assumptions, discount rates, and depeg thresholds may be adjusted in real time.
Final Thoughts
Portfolio Margin Mode offers unparalleled capital efficiency for sophisticated traders managing complex multi-market strategies. By unifying spot, futures, and options under a single risk engine—and intelligently recognizing hedges—it reduces redundancy in margin allocation and supports more aggressive yet controlled positioning.
However, its complexity demands deep understanding of derivatives pricing, delta hedging, and systemic risks like stablecoin depegs.
