In the fast-evolving world of cryptocurrency derivatives trading, efficient capital utilization is a key differentiator for traders. As a leading global derivatives exchange, OKX continues to innovate its margin infrastructure to empower users with smarter, more flexible account management tools. The evolution from cross-currency margin mode to the advanced Portfolio Margin Mode 2.0 marks a significant leap in how traders can manage risk and optimize their positions across spot and derivatives markets.
This article provides a detailed, SEO-optimized comparison between cross-currency margin mode and portfolio margin mode, helping both intermediate and advanced traders understand the benefits, eligibility, and real-world impact of each system.
Understanding the Core Concepts
Before diving into the differences, it’s essential to grasp what these margin modes are and how they function within the OKX unified trading account framework.
The unified account structure allows seamless fund allocation across multiple product lines—spot, margin, futures, perpetual swaps, and options—without manual transfers. However, the way collateral is calculated and applied varies significantly depending on the selected margin mode.

Key Differences: Cross-Currency vs. Portfolio Margining
1. Account Mode Overview
| Feature | Cross-Currency Margin Mode | Portfolio Margin Mode 1.0 (Derivatives Hedging) | Portfolio Margin Mode 2.0 (Spot-Derivatives Hedging) |
|---|---|---|---|
| Supported Products | All: Spot, Margin, Futures, Perpetuals, Options | Derivatives only | Full integration of Spot + Derivatives |
| Minimum Net Asset Requirement | > $50,000 | > $100,000 | > $100,000 |
| Eligible Collateral | All assets in the trading account (valued in USD using coin discount rates) + Unrealized P&L from derivatives positions | Same as above, but assessed under portfolio risk models | Includes spot holdings with delta-neutral hedging capabilities |
| Options Valuation | Only short options count toward usable margin; long options are isolated | Both long and short options are evaluated in margin calculation | Full integration of both long and short options |
| Position Margin Calculation | Per-position basis using position tier tables | Risk-based aggregation by risk units under multiple stress scenarios | Same as 1.0, plus spot delta offsets included in risk units |
2. Risk Evaluation Methodology
- Cross-Currency Margin Mode: Each position is evaluated independently. For example, an ETH-USDT perpetual swap has its own isolated maintenance margin based on volatility and leverage.
- Portfolio Margin Modes (1.0 & 2.0): Positions are grouped into risk units (e.g., BTC-denominated or USDT-settled), and their combined exposure is tested under various market stress scenarios. The highest potential loss across these scenarios determines the total required margin.
- Key Innovation in 2.0: Spot assets like BTC or ETH can now be used to offset directional (delta) risk in derivatives positions. For instance, holding 100 BTC spot can reduce margin requirements for short BTC futures if they hedge each other.
Real-World Example: How Portfolio Margining Saves Capital
Let’s consider a practical scenario to illustrate the efficiency gains:
| Parameter | Value |
|---|---|
| Spot Holding | 148 ETH |
| Derivatives Positions | -30,000 contracts ETH-USDT-SWAP (short) +20,000 contracts ETH-USDT-0930 (call option long) |
| Maintenance Margin Under: | |
| • Cross-Currency Mode | 7,947 USD |
| • Portfolio Margin 1.0 | 33,665 USD (higher due to lack of offset mechanisms) |
| • Portfolio Margin 2.0 | 9,618 USD (with 100 ETH spot used for delta hedging) |
| Optimization Gain (1.0 → 2.0) | ~70% reduction in required margin |
Key Takeaways:
- Traders with substantial spot holdings and offsetting derivatives positions benefit most from Portfolio Margin Mode 2.0.
- Despite higher minimum equity requirements, the capital efficiency improvement is dramatic—especially for institutional or semi-institutional traders.
- In some cases, Portfolio Margin 2.0 even outperforms cross-currency mode in terms of lower margin requirements.

Who Should Use Which Mode?
✅ Cross-Currency Margin Mode Is Ideal For:
- Retail traders with smaller portfolios (< $50K)
- Users who primarily trade spot or isolated derivatives
- Those seeking simplicity over advanced optimization
✅ Portfolio Margin Mode 1.0 Suits:
- Professional traders managing complex derivatives books
- Users with offsetting options or futures positions
- Accounts with net asset value exceeding $100K
✅ Portfolio Margin Mode 2.0 Is Best For:
- Institutional traders and hedge funds
- Traders maintaining large spot inventories alongside derivatives
- Strategies involving delta-neutral or market-neutral positioning
Frequently Asked Questions (FAQ)
Q: What is the main advantage of Portfolio Margin Mode 2.0 over earlier models?
A: The key enhancement is the inclusion of spot assets in risk calculation, allowing them to offset delta exposure in derivatives. This reduces redundant margin allocation and improves capital efficiency.
Q: Can I switch between margin modes freely?
A: Yes, users can switch between modes at any time via the account settings page. However, switching to Portfolio Margin requires meeting the $100K net asset threshold.
Q: Are there any risks associated with Portfolio Margin?
A: While it improves efficiency, Portfolio Margin increases interdependence between positions. A sharp market move affecting multiple assets simultaneously could trigger faster liquidations compared to isolated margining.
Q: Does OKX support cross-margin for options trading?
A: In cross-currency mode, only short options contribute to margin; long options are excluded. In Portfolio Margin modes, both long and short options are factored into risk assessment.
Q: How does OKX calculate the discount rate for collateral?
A: Each cryptocurrency has a haircut (discount) applied based on its volatility, liquidity, and market depth. Stablecoins like USDT typically have higher collateral efficiency (lower discounts) than volatile altcoins.
Q: Is there a fee to use Portfolio Margin Mode?
A: No. There are no additional fees for using any margin mode on OKX—the choice is purely functional and based on your trading strategy.
