How to use the "Portfolio Margin" feature on Binance? (Capital Efficiency)

Understanding Portfolio Margin Mechanics

1. Portfolio Margin calculates margin requirements based on the overall risk exposure of a user’s entire derivatives position set, rather than applying isolated margin rules per contract.

2. It aggregates long and short positions across multiple underlying assets and maturities to compute net risk using real-time volatility and correlation data.

3. The system applies stress-scenario simulations—such as 3% price shocks or implied volatility spikes—to determine worst-case loss thresholds.

4. Users must maintain a minimum portfolio margin ratio of 100%, calculated as (Total Equity) / (Required Margin), with automatic liquidation triggered below 75%.

5. Cross-margin functionality allows unrealized PnL from profitable positions to offset margin deficits in losing ones, provided both reside within the same portfolio margin account.

Eligibility and Account Setup

1. Applicants must complete Binance’s Advanced Derivatives Trading Certification and pass a knowledge assessment covering margin mechanics and liquidation logic.

2. A minimum 30-day trading history on Binance Futures is required, including at least 10 executed trades with non-zero position sizes.

3. Users must hold at least 5 BTC equivalent in total equity across spot, margin, and futures wallets before enabling Portfolio Margin.

4. KYC Level 2 verification is mandatory, and applicants residing in jurisdictions where portfolio margin is prohibited—including the United States, Canada, and Singapore—are automatically excluded.

5. Activation requires explicit consent to the Portfolio Margin Terms & Conditions document, which outlines liability for cross-position contagion during extreme market events.

API Integration for Automated Management

1. Developers use @binance/derivatives-trading-portfolio-margin to access REST endpoints under the /papi/v1/ namespace for real-time margin status retrieval.

2. The accountInformation() method returns granular breakdowns: total margin balance, used margin, available margin, and individual position margin contributions.

3. WebSocket streams via papi/depth and papi/account deliver sub-100ms updates on margin ratio fluctuations and forced liquidation triggers.

4. Custom timeout and proxy configurations are supported to ensure reliability during high-latency network conditions or institutional firewall environments.

5. All API calls require HMAC-SHA256 authentication signed with the user’s API secret, and rate limits apply strictly per IP and API key pair.

Risk Parameter Customization

1. Traders may adjust the “Risk Sensitivity Multiplier” between 0.8 and 1.5 to tighten or relax margin calculations based on personal risk tolerance.

2. Volatility floors can be manually set per underlying asset—for example, enforcing a minimum 25% annualized volatility assumption for BTCUSD perpetuals regardless of market conditions.

3. Correlation coefficients between pairs like ETHUSD and SOLUSD can be overridden to reflect proprietary macro views, altering net delta and gamma exposure assessments.

4. Users may exclude specific instruments from portfolio aggregation—such as options contracts—forcing them to be margined separately under standard SPAN rules.

5. Margin buffer thresholds for warning notifications are configurable in percentage points, with default alerts issued at 110%, 105%, and 101% margin ratio levels.

Frequently Asked Questions

Q: Can I transfer funds between my Portfolio Margin account and my Unified Trading Account?Yes. Internal transfers are supported via the /papi/v1/transfer endpoint or the web interface, with settlement occurring instantly and no fees applied.

Q: Does Portfolio Margin support coin-margined and USDT-margined contracts simultaneously?Yes. Both contract types coexist within the same portfolio, and their risk exposures are converted into a unified quote currency—USDT—for consolidated margin computation.

Q: What happens to open orders during a forced liquidation event?All unfilled limit and stop-market orders tied to positions under liquidation are automatically canceled before the liquidation engine executes market sells or buys.

Q: Are interest accruals applied to borrowed margin in Portfolio Margin accounts?No. Portfolio Margin does not involve borrowing; it reallocates existing equity across positions. Interest charges only apply in isolated margin or cross-margin modes outside this framework.
