In a strategic move to strengthen market stability, improve liquidity, and optimize user trading conditions, OKX has announced upcoming adjustments to key portfolio margin parameters. These updates—targeting MR1 (spot shock), MR4 (basis risk), MR6 (extreme move), MR7 (minimum charge), and MR9 (stablecoin depegging risk)—are designed to better reflect current market dynamics while safeguarding traders against volatility and systemic risks.
The changes will be rolled out in phases throughout January 2025, with most taking effect during scheduled maintenance windows. Below is a comprehensive breakdown of what’s changing, why it matters, and how it impacts your trading strategy.
Understanding Portfolio Margin Parameters
Portfolio margining allows traders to use their entire account balance as collateral across multiple positions, increasing capital efficiency. However, this flexibility requires robust risk modeling. That’s where margin parameters like MR1 through MR9 come into play—they simulate worst-case market scenarios to ensure sufficient collateral is held.
By fine-tuning these parameters, OKX aims to balance risk control, capital efficiency, and trading flexibility in increasingly volatile crypto markets.

MR1: Spot Shock Adjustment – Smoother Volatility Modeling
The MR1 parameter models potential spot price shocks across different asset classes. The updated thresholds reflect a more conservative approach, particularly for major cryptocurrencies.
Before vs. After: MR1 Changes
BTC & ETH
- Old: ±0%, 5%, 10%, 15%
- New: ±0%, 4%, 8%, 12% → 20% reduction in maximum simulated shock
Mid-Cap Assets (LTC, XRP, ADA, etc.)
- Old: ±0%, 7%, 14%, 20%
- New: ±0%, 6%, 12%, 18% → 10–15% lower stress levels
Other Tokens
- Unchanged: ±0%, 8%, 16%, 25%

This recalibration suggests that OKX expects relatively lower near-term volatility for blue-chip assets, potentially improving margin efficiency for BTC and ETH positions.
MR6: Extreme Move Thresholds Reduced
MR6 defines the largest single-period price drop or spike assumed in stress tests. Lower values mean less aggressive worst-case assumptions, which could free up margin capital.
Key Updates
| Asset Group | Previous | New | Change |
|---|---|---|---|
| BTC, ETH | ±30% | ±24% | ↓ 20% |
| SOL, BNB, DOGE, XRP, etc. | ±40% | ±36% | ↓ 10% |
| Others | ±50% | ±50% | No change |
While still substantial, these reductions acknowledge improved market resilience and deeper liquidity in top-tier altcoins. Traders may see slight improvements in available buying power under portfolio margin.
MR4: Basis Risk Cut Across the Board
Basis risk refers to the divergence between spot and futures prices. MR4 quantifies annualized volatility used in cross-market risk calculations.
New Annualized Move Risk Levels
| Asset Group | Previous | New | Impact |
|---|---|---|---|
| BTC, ETH | 7.50% | 5.00% | ↓ 33% |
| SOL, XRP, ADA, DOGE, etc. | 22.50% | 15.00% | ↓ 33% |
| Others | 45.00% | 30.00% | ↓ 33% |
This uniform 33% reduction signals increased confidence in derivatives market efficiency. Lower basis risk assumptions can reduce margin requirements on futures and options positions—especially beneficial for arbitrage and hedging strategies.
MR7: Minimum Charge Thresholds Raised Significantly
The MR7 parameter applies multipliers to large positions to discourage excessive concentration risk. The revised tiers dramatically increase the thresholds before higher multipliers kick in.
Before (Old Tier Structure)
- Tier 1: $0–$10k → ×1
- Tier 7: >$700k → ×12
After (New Tier Structure)
- Tier 1: $0–$250k → ×1
- Tier 7: >$4M → ×12
This means traders can now hold positions up to **$250,000** before any multiplier applies—compared to just $10,000 previously. The change greatly enhances scalability for institutional and high-volume traders using portfolio margin.
MR9: Stablecoin Depegging Risk – Expanded Tier Capacity
Stablecoin reliability is critical in leveraged trading. MR9 measures risk when USDT or USDC deviates from $1. The new structure maintains the same percentage penalties but significantly expands tier thresholds.
Major Improvements
- Tier 4: From $10M–$20M → Now $10M–$30M
- Tier 5: Up to $50M (was $30M)
- Tier 8 (largest): Starts at $120M (was $50M)
This adjustment accommodates growing stablecoin usage in large-scale trading operations without triggering excessive margin calls during minor depegs.
For example:
- A $75M cross-currency hedge now falls under Tier 6 instead of Tier 8
- Penalty drops from flat 30–40% to tiered rates starting at 4%
Such changes support macro hedging strategies and reduce over-collateralization risks.
Why These Changes Matter
These parameter updates are not isolated tweaks—they represent a broader shift toward smarter risk modeling and greater capital efficiency on OKX.
By aligning stress-test assumptions with real-world market behavior, OKX enables traders to:
- Hold more diversified portfolios
- Reduce unnecessary margin buffers
- Execute complex strategies with improved leverage utilization
Moreover, the adjustments indicate maturing crypto markets—where extreme moves are becoming less frequent and stablecoins are proving resilient under pressure.
Frequently Asked Questions (FAQ)
Q: When will the changes take effect?
A:
- MR1 and MR6 updates go live between 8:00 AM – 10:00 AM UTC on January 6, 2025
- MR7 adjustments apply during the same window on January 15, 2025
- MR4 and MR9 changes are effective immediately upon announcement
Q: How do these changes affect my current positions?
A: If you're using portfolio margin, your margin requirements may decrease slightly—especially for BTC/ETH spots and futures. No action is required; adjustments are automatic.
Q: Are these changes increasing or decreasing risk?
A: They reflect reduced perceived risk based on historical data and improved market depth. Risk controls remain strong, but assumptions are now more calibrated to actual conditions.
Q: Will smaller traders benefit from these updates?
A: Yes—especially from the MR7 changes. Even if you don’t hit high tiers, the overall system becomes more efficient, leading to tighter margin calculations across the board.
Q: What happens if a stablecoin drops below $0.95?
A: The MR9 framework ensures escalating penalties based on exposure size. For instance, a $40M position facing a severe depeg would face a 27–30% charge—designed to cover potential losses without collapsing the system.
